Gene flow and climate-associated genetic variation in a vagile habitat specialist
<p>Previous work in landscape genetics suggests that geographic isolation is of greater importance to genetic divergence than variation in environmental conditions. This is intuitive when configurations of suitable habitat are the dominant factor limiting dispersal and gene flow, but has not been thoroughly examined for habitat specialists with strong dispersal capability. Here, we evaluate the effects of geographic and environmental isolation on genetic divergence in a vagile invertebrate with high habitat specificity and a discrete dispersal life stage: Dod's Old World swallowtail butterfly, <i>Papilio machaon dodi</i>. In Canada, <i>P. m. dodi </i>are generally restricted to eroding habitat along major river valleys where their larval host plant occurs. A series of causal and linear mixed effects models indicate that divergence of genome-wide single nucleotide polymorphisms is best explained by a combination of environmental isolation (variation in summer temperatures) and geographic isolation (Euclidean distance). Interestingly, least-cost path and circuit distances through a resistance surface parameterized as the inverse of habitat suitability were not supported. This suggests that, although habitat associations of many butterflies are specific due to reproductive requirements, habitat suitability and landscape permeability are not equivalent concepts due to considerable adult vagility. We infer that divergent selection related to variation in summer temperatures has produced two genetic clusters within <i>P. m. dodi</i>, differing in voltinism and diapause propensity. Within the next century, temperatures are predicted to rise by amounts greater than the present-day difference between regions of genetic clusters, potentially affecting the persistence of the northern cluster under continued climate change.</p>
Data from: Climate-dependent variation in cold tolerance of weedy rice and rice mediated by OsICE1 promoter methylation
<div class="WordSection1"> <p><span><span><span><span>The mechanisms by which weedy rice (<i>Oryza sativa</i> f. <i>spontanea</i>) has adapted to endure low-temperature stress in northern latitudes remain unresolved. In this study, we assessed cold tolerance of 100 rice varieties and 100 co-occurring weedy rice populations, which were sampled across a broad range of climates in China. A parallel pattern of latitude-dependent variation in cold tolerance was detected in cultivated rice and weedy rice. At the molecular level, differential cold tolerance was strongly correlated with relative expression levels of <i>CBF</i> cold response pathway genes and with methylation levels in the promoter region of <i>OsICE1</i>, a regulator of this pathway. Among all methylated cytosine sites of the <i>OsICE1</i> promoter, levels of CHG and CHH methylation were found to be significantly correlated with cold tolerance among accessions. Furthermore, within many of the collection locales, weedy rice shared identical or near-identical <i>OsICE1 </i>methylation patterns with co-occurring cultivated rice. These findings provide new insights on the possible roles that methylation variation in the <i>OsICE1</i> promoter may play in cold tolerance, and they suggest that weedy rice can rapidly acquire cold tolerance via methylation patterns that are shared with co-occurring rice cultivars. </span></span></span></span></p> </div> <p> </p>
