Data from: Rapid, parallel evolution of field mustard (Brassica rapa) under experimental drought
<p>Climate change is driving evolutionary and plastic responses in populations, but predicting these responses remains challenging. Studies that combine experimental evolution with ancestor-descendant comparisons allow assessment of the causes, parallelism, and adaptive nature of evolutionary responses, although such studies remain rare, particularly in a climate change context. Here, we created experimental populations of Brassica rapa derived from the same natural population and exposed these replicated populations to experimental drought or watered conditions for four generations. We then grew ancestors and descendants concurrently, following the resurrection approach. Experimental populations under drought showed rapid evolution of earlier flowering time and increased specific leaf area, consistent with a drought escape strategy and observations in natural populations. Evolutionary shifts followed the direction of selection and increased fitness under drought, indicative of adaptive evolution. Evolution to drought also occurred largely in parallel among replicate populations. Further, traits showed phenotypic plasticity to drought, but the direction and effect size of plasticity varied. Our results demonstrate parallel evolution to experimental drought, suggesting that evolution to strong, consistent selection may be predictable. Broadly, our study demonstrates the utility of combining experimental evolution with the resurrection approach to investigate responses to climate change.</p>
[Data from:] Genetic Analysis Reveals Three Novel QTLs Underpinning a Butterfly Egg-Induced Hypersensitive Response-Like Cell Death in Brassica Rapa
<p><strong>Background</strong></p> <p>Cabbage white butterflies (<em>Pieris</em> spp.) can be severe pests of <em>Brassica</em> crops such as Chinese cabbage, Pak choi (<em>Brassica rapa</em>) or cabbages (<em>B. oleracea</em>). Eggs of <em>Pieris</em> spp. can induce a hypersensitive response-like (HR-like) cell death which reduces egg survival in the wild black mustard (<em>B. nigra</em>). Unravelling the genetic basis of this egg-killing trait in <em>Brassica</em> crops could improve crop resistance to herbivory, reducing major crop losses and pesticides use. Here we investigated the genetic architecture of a HR-like cell death induced by <em>P. brassicae</em> eggs in <em>B. rapa.</em></p> <p><strong>Results</strong></p> <p>A germplasm screening of <em>B. rapa</em> 56 accessions, representing the genetic and geographical diversity of a <em>B. rapa</em> core collection, showed phenotypic variation for cell death. An image-based phenotyping protocol was developed to accurately measure size of HR-like cell death and was then used to identify two accessions that consistently showed weak (R-o-18) or strong cell death response (L58). Screening of 160 RILs derived from these two accessions resulted in three novel QTLs for P<em>ieris</em> b<em>rassicae-</em>induced cell death on chromosomes A02 (<em>Pbc1</em>), A03 (<em>Pbc2</em>), and A06 (<em>Pbc3</em>). The three QTLs <em>Pbc1-3</em> contain cell surface receptors, intracellular receptors and other genes involved in plant immunity processes, such as ROS accumulation and cell death formation. Synteny analysis with <em>A. thaliana</em> suggested that <em>Pbc1</em> and <em>Pbc2</em> are novel QTLs associated with this trait, while <em>Pbc3</em> contains also LecRK-I.1, a gene of <em>A. thaliana</em> previously associated with cell death induced by a <em>P. brassicae</em> egg extract.</p> <p><strong>Conclusions</strong></p> <p>This study provides the first genomic regions associated with the <em>Pieris</em> egg-induced HR-like cell death in a <em>Brassica</em> crop species. It is a step closer towards unravelling the genetic basis of an egg-killing crop resistance trait, paving the way for breeders to further fine-map and validate candidate genes.</p>
Data from: Rapid-cycling Brassica rapa evolves even earlier flowering under experimental drought
<p><strong>Premise</strong></p> <p>Changes in climate can impose selection on populations and may lead to rapid evolution. One such climatic stress is drought, which plant populations may respond to with escape (rapid growth and early flowering) or avoidance (slow growth and efficient water use). However, it is unclear if drought escape would be a viable strategy for populations that already flower early from prior selection.</p> <p><strong>Methods</strong></p> <p>In an experimental evolution study, we subjected rapid-cycling <em>Brassica rapa</em> (RCBr), which was previously selected for early flowering, to four generations of experimental drought or watered conditions. We then grew ancestral and descendant populations concurrently under drought and watered conditions to assess evolution, plasticity, and adaptation.</p> <p><strong>Results</strong></p> <p>RCBr evolved under drought had earlier flowering and lower water-use efficiency than RCBr evolved under watered conditions, indicating evolutionary divergence. The drought descendants also had a trend of earlier flowering compared to ancestors, indicating evolution. Evolution of earlier flowering under drought followed the direction of selection and increased fitness, and was consistent with studies in natural and experimental populations of this species, suggesting adaptive evolution.</p> <p><strong>Conclusions</strong></p> <p>We found evidence for rapid adaptive evolution of drought escape in RCBr and little evidence for constraints on flowering, even though RCBr already flowers extremely early. Our results suggest that some populations may harbor sufficient genetic variation for evolution even after strong selection has occurred. Our study also illustrates the utility of combining artificial selection, experimental evolution, and the resurrection approach to study the evolution of functional traits.</p>
