While some samples still had relatively small percentages of reads mapping to the baboon reference genome, these generally also exhibited the highest fold increases. MBD binding may in principle select for genomic regions with relatively high CpG-methylation density, leading to dropout of other loci. Assessment of the concordance between blood- and feces-derived reads from the same individual was complicated by the correlation in ddRADseq between total reads and expected RADtags recovered and thereby SNPs discovered: a given RADtag is sequenced at a frequency inversely proportional to the deviation of its length from the mean of the size selection.
Thus, we had to discern between dropout due to coverage-related stochasticity inherent in ddRADseq 27 and that due to MBD enrichment. To perform this comparison, we computed the proportion of unique alleles between blood- and feces-derived RADtags from the same individual.
For this test, we controlled for variation in sequencing coverage by randomly sampling reads as necessary in order to equalize total coverage among same-individual samples. Allelic dropout due to MBD enrichment would result in a higher proportion of alleles unique to blood-derived libraries relative to feces-derived libraries.
Figure 3 Concordance between blood- and feces-derived genotyping data from the same individuals. Colors symbolize the six captive individuals included in our study. Within these individuals, we did not find significant differences in A the proportion of unique alleles or B inbreeding coefficients from blood- and feces-derived libraries. Distances between feces- and blood-derived sets of genotypes from the same individual are minimal, indicating that noise added by the enrichment method is dwarfed by the population structure signal in this baboon population dataset.
Full size image Dropout of entire RADtags is easily detectable given a reference genome or sufficient samples for comparison; dropout of a single allele at heterozygous sites is a more insidious potential bias. Inbreeding coefficients F computed from same-individual RADtags exhibited in some cases higher values for feces-derived samples Fig.
For this test, we also controlled for variation in sequencing coverage as described above. Stringent filtration of SNP sets, as would be implemented in a standard population genetic study, reduced the apparent biases attributable to fecal enrichment, measured both as total SNPs with a significant association with sample type unfiltered: 25, out of ,, or 4.
Though more work is needed to quantify more exactly the extent and causal factors that lead to missingness, many population genetic analyses are robust to the low level of dropout our analyses reveal in addition to that which is inherent in the RADseq family of techniques Discussion Our methylation-based capture method achieves substantial enrichment of host DNA from fecal samples.
Using our revised protocol developed through experimentation, we produced a mean fold enrichment on our final library consisting entirely of fecal DNA obtained noninvasively under remote field conditions, with most samples nearly a decade old. A mean Using fecal and blood DNA obtained from captive animals, we further demonstrate that feces-derived genotyping data following our method are concordant with corresponding data obtained from blood. Feces are among the most readily accessible sources of information on wild animals 1 , and are particularly useful for population-level studies or studies of endangered or elusive species for which obtaining high-quality samples is difficult or undesirable.
By exploiting methylation differences rather than sequence differences between host and bacterial DNA, FecalSeq is an enrichment strategy that requires neither prior genome sequence knowledge nor the use of high-quality DNA for preparation of capture baits. This results in enrichment which is both inexpensive and replicable. The enrichment procedure is also relatively rapid and uncomplicated.
Using a well plate, we performed two sequential rounds of enrichment on all forty samples in our final library within a day see Supplemental Protocol. Compared to comparable experiments using high-quality DNA samples such as blood, our enrichment method introduces extremely low added costs. After excluding shared costs such as DNA extraction, library preparation, and sequencing, major costs associated with our method are qPCR reagents for initial quality assessment of fecal DNA samples and enrichment reagents for capturing the host genome.
For our enrichment protocol, the amount of reagents used will vary based on the starting proportion of host DNA in the sample see Supplemental Protocol. Assuming fecal DNA samples on average contain 2. Based on our experience, most fecal DNA samples contain less than 2.
These costs represent a substantial decrease relative to enrichment methods based on oligonucleotide-based sequence capture 5 , 6 , which at present represents the only other published strategy for enriching fecal DNA. Snyder-Mackler et al. Overall, our strategy therefore decreases the cost of enrichment by about one order of magnitude. Importantly, FecalSeq is to our knowledge the first genomic-scale fecal DNA enrichment method that is compatible with most downstream library preparation methods for massively parallel sequencing.
Through our use of ddRADseq, we demonstrate that our method facilitates low-cost high-capacity genotyping of wild populations without introducing significant bias.
Further, because ddRADseq is customizable 27 , there is substantial flexibility for researchers to optimize the number of samples and the fraction of the genome sequenced for particular research questions. This is not possible for libraries prepared using targeted sequence capture, which are therefore currently limited mainly to low-coverage analyses at the population level 6.
Transcription of sequence capture baits from reduced-representation libraries may potentially help address this problem 14 , 15 , 16 , but its efficacy for fecal DNA has yet to be demonstrated. Although ideally suited to taxa with a reference genome, genotyping via double-digest RADseq is possible for species that lack a closely related reference genome. We aligned our sequencing reads to the baboon reference genome for this study, but our approach is likely also applicable to species without a reference genome.
A reference genome from a more phylogenetically distant species can be used, although reads from divergent regions will fail to map. If a nearby genome is not available, an additional pre-screening step would be necessary, in which exogenous reads are filtered out through comparison to the nearest available genome, before proceeding to clustering and variant identification as per normal reference-free ddRADseq methods. Although these caveats will be mitigated as more genomes become available, the proximity of study individuals to an available reference genome is an important consideration when deciding if ddRADseq methods, including ddRADseq following our enrichment method, are suitable to address the research goals.
We robustly found that sequencing efficiency percentage of reads assigned to target genome of MBD-enriched fecal DNA libraries correlates strongly with starting proportions of host DNA, echoing findings using other capture methods 6.
Future attention should therefore be directed towards fecal sample collection, storage, and extraction methods that maximize the selective recovery of host nuclear DNA We found that, for unknown reasons, starting host DNA concentration for fecal samples collected in captive conditions was higher than that of fecal samples collected from the wild, despite consistent sample collection and processing protocols.
We speculate that these differences may be due to either the freshness of samples collected in captivity or to dietary differences between captivity and the wild.
Because our wild fecal samples were collected under common biological field conditions e. Low starting proportions of host DNA present a challenge not only because they result in lower sequencing efficiency, but also because they correlate with low absolute quantities of DNA belonging to the host organism.
In some cases, particularly in samples collected from wild animals under field conditions, starting proportions of host DNA were so low that only approximately 0. Given the large genome sizes of baboons approximately 3 Gb and many other vertebrates, substantial allelic dropout is expected in these cases. Significantly, this challenge cannot be fully addressed by this or any other enrichment method and remains an important consideration for researchers working with feces.
It can be minimized, however, by optimizing the enrichment procedures to maximize the recovery of target DNA present in a fecal DNA sample, as well as by increasing the total amount of starting fecal DNA.
While this may be undesirable for studies requiring the matrilineally inherited marker, it also precludes the disproportionately high representation of mitochondrial DNA that is typical in libraries prepared using the targeted sequence capture approach 5 , 6 , 9 , FecalSeq may, however, co-enrich nuclear DNA from exogenous eukaryotes such as from plant or animal digesta.
Care should therefore be taken to minimize the presence of exogenous eukaryotic tissues or cells, although the degree to which this is a problem in practice is currently unknown. As cell-wall-bound plant cells may be more likely to pass through the digestive tract intact, extraction methods that minimize lysis of cell walls should be preferred.
While our comparisons of inbreeding coefficients, unique alleles, and locus-by-locus statistical tests from matched blood and fecal samples revealed no significant effect of sample type and therefore enrichment, our small sample size limits our power to detect differences with small effect size. Subsequent studies with larger sample sizes may detect a significant effect of enrichment, but one which may be negligible or correctable for some applications. Since PCR amplification of DNA from feces was first achieved in the s 3 , 34 , 35 , noninvasive genetic studies have revolutionized our understanding of the evolution, ecology, and behavior of nonmodel organisms.
By facilitating low-cost genomic-scale sequencing from feces, our method connects a community of field researchers with the benefits of massively parallel sequencing, ushering noninvasive organism studies into the genomic age.
The individuals were of either P. In separate sedation events, blood and feces were collected from the same individual who was isolated for the duration of the sedation. In addition, we collected or obtained fecal samples from 46 wild baboons in Zambia. In contrast to the SNPRC samples, however, these samples were collected noninvasively from unhabituated animals in remote field conditions.
Samples therefore could not be attributed to particular animals, although samples were selected to avoid duplication using either field observations or geographic distance. All procedures involving live animals were carried out in accordance with relevant guidelines and regulations. Sedation and blood draws were performed under the supervision of a veterinarian and animals were returned immediately to their enclosures following recovery. Sample collection in Zambia was conducted with approval by the Animal Studies Committee of Washington University assurance A—01 and following local laws and regulations in Zambia.
In some cases, multiple DNA extractions from the same individuals were necessary when DNA was depleted over the course of this study. Amplification was conducted using universal mammalian MYCBP primers 36 and evaluated against a standard curve constructed from the liver DNA of an individual baboon.
Samples and standards were run in duplicate alongside positive and negative controls see Supplemental Protocol for full details. After combining beads and DNA, we incubated the mixture at room temperature with rotation for 15 min. For samples in library B, we conducted three expanded wash steps to maximize the removal of unbound DNA.
The eluted DNA was then separated by magnet, purified with 1. Our pilot sequencing results from libraries A and B revealed large variation in the percentage of reads mapping to the baboon genome, with mapping percentages ranging from 1. The resulting post-enrichment proportion of baboon and E. Based on these capture optimization experiments, we prepared subsequent libraries using a version of the protocol incorporating modifications demonstrated to improve enrichment.
We therefore aimed to minimize both the absolute and relative amount of nonmethylated DNA binding to the bead complex. Because the amount of CpG-methylated host DNA in feces is extremely low, this modification also greatly decreased the cost of the reagents. Through our optimization experiments, we found that incorporating an additional wash step reduced the amount of contaminating nonmethylated DNA captured.
Finally, we developed a method for serial enrichment of the samples repeating the enrichment protocol , which substantially improved results. There was no question in my mind. His hands were everywhere and I felt shaky all over from excitement.
Breaking the kiss his hands started tugging on my shorts.
I stood up nervous but so incredibly excited I couldn't keep from trembling. I wasn't sure if he wanted everything off. I don't want our first time to be on this couch and if you take those off I'm a goner. I'd just had the absolute best week of my life and now I had to end it with a family dinner. One where my father would be present. I wished I hadn't promised my mom I'd bring Will ow.
This was the last thing I wanted her to witness. Will ow came up behind me and wrapped her arms around my shoulders and leaned down to kiss my cheek. My University of Alabama t-shirt looked good on her. She no longer wore Cage's shirts around the apartment. I wanted her in mine. Maybe it was a little caveman but I didn't care. We can work out your reward for a job well done later. You've given my fantasies some fuel. Shaking my head to clear the images of Will ow straddling me and crying out my name I studied the screen in front of me again.
She was right. I needed to finish this. Like yesterday. But I'd spent every spare minute I had with Will ow and I wouldn't have had it any other way. The apartment door opened and in walked Cage followed by Preston. They'd been at baseball practice. Both of them were dirty and sweaty. He'd been "paying" smart chics to do his homework since middle school.
However, his paying normally didn't involve cash. Preston's eyes shifted between the two of us. I could see the curious questions in his eyes. How were we getting along? Did we ever fight? Wasn't it uncomfortable? And the truth was no. Cage was rarely here. The shower cut off and I jumped up. Both guys stared at me like I was crazy. The idea of Low walking out in her towel thinking it was just me here scared the shit out of me.
I ignored them and made my way to the door.
They're on the bed. I didn't look back at either of them but I could feel their eyes boring into me. No doubt Preston was amused and Cage was pissed off.
A pair of pink silk panties that consisted of very little materiel and a matching bra lay on top of that brown sundress that reminded me of chocolate. Picking them all up I headed back to the bathroom making sure to keep her underclothes hidden from prying eyes. She cracked the door and reached out and took them from my hands.
Smiling bashfully up at me I wanted to push my way inside but kept my cool. Preston started up first, "A little possessive there aren't ya bud. Afraid I'm gonna get a peek at Miss Low in her towel. I turned and glared at him. He was leaning against the counter looking so damn sure of himself. Always has been. Just ignore him. It was just as big as I had pictured in my head. The pale yellow color of the house was set off by large white hurricane shutters. It was beach front and the main part of the house started on the second floor.
The bottom was all garage.
Which made sense for the Mercedes King of the Gulf Coast to have a large garage. Something was bothering him but I was almost afraid to ask.
Instead of walking around to get my door he slammed his door shut and stood glaring up at those large glass paned doors as if he wanted to rip them off their hinges. As quietly as I could, I opened my door and made my way around the front of his truck.
Maybe he was having second thoughts. I knew he was back home due to family issues.
But this was much more intense than I'd expected from the perfect family I pictured him to have. Especially after meeting his bubbly sweet gorgeous sister. He jerked his head toward me when I stopped beside him and the angry scowl melted and he frowned.
He's not. Missing family meals must really rank high on the shit list around here. She was excited," he let out a sigh and reached down to clasp my hand in his. Nothing that happens tonight has anything to do with your presence. Total 26 Pages: Create a free website or blog at WordPress.
Because of Low Sea Breeze 2 17 Author: Abbi Glines What? Standing up I closed the distance she'd been afraid to bridge. You have me. I took her face in my hands and held her gaze. I was going to stay here tonight anyway. Let's go play," I replied. My stomach rumbled and I looked at Larissa. You can sit beside me and eat too. Turning to Will ow for a translation, Larissa proceeded to chant, "Martus bite bites" "Bite bites is what she likes to call eating," Will ow explained.
Willow The television ill uminated the dark apartment when I stepped inside. Raising my eyes I looked at him and he shook his head. Chapter Seventeen Marcus I'd just had the absolute best week of my life and now I had to end it with a family dinner. And neither did she. I was almost positive she liked it. She smirked and shook her head no. I've distracted you all week.
