Abstract Karrikins (KARs) are chemicals in smoke that can enhance germination of many plants. Lettuce (Lactuca sativa) cv. Grand Rapids germinates response to nanomolar karrikinolide (KAR1). is much less responsive KAR2 or a mixture synthetic strigolactone analogs, rac-GR24. We investigated the molecular basis selective and sensitive KAR1 perception lettuce. The lettuce genome contains two copies KARRIKIN INSENSITIVE2 (KAI2), which Arabidopsis (Arabidopsis thaliana) encodes receptor required...
Cowpea is a highly drought-adapted leguminous crop with great promise for improving agricultural sustainability and food security. Here, we report analyses derived from array-based genotyping of 2,021 accessions constituting core subset the world's largest cowpea collection, held at International Institute Tropical Agriculture (IITA) in Ibadan, Nigeria. We used this dataset to examine genetic variation population structure worldwide cowpea. confirm that primary pattern two geographically...
Direct observation is central to our understanding of adaptation, but evolution rarely documented in a large, multicellular organism for more than few generations. In this study, we observed across century-scale competition experiment, barley composite cross II (CCII). CCII was founded 1929 Davis, California, with thousands genotypes, found that natural selection has massively reduced genetic diversity, leading single lineage constituting most the population by generation 50. Selection...
ABSTRACT The interplay between genetics and the environment determines a population’s ability to survive. Plants, being immobile, are particularly vulnerable environmental shifts must adapt their local or face extinction. While considerable efforts have been devoted identifying adaptive genetic variation model its relationship with climate, role of deleterious has largely overlooked. To address this gap, we studied landscape genomics Vitis arizonica , grape species endemic American Southwest...

<ns3:p>Background The goal of the Fifth Annual Baylor College Medicine & DNAnexus Structural Variation Hackathon was to push forward research on structural variants (SVs) by rapidly developing and deploying open-source software. event took place in-person virtually in August 2023, when 49 scientists from 14 countries 8 U.S. states collaboratively worked projects address critical gaps field genomics. hackathon concentrated bioinformatic workflows for following challenges: RNA...
Single-stranded RNA molecules have the ability to form intramolecular bonds between nucleotides and create secondary structures. These structures can phenotypic effects, meaning mutations that alter structure may be subject natural selection. Here we examined population genetics of these within Arabidopsis thaliana genes. We began by identifying derived SNPs with potential coding regions, using a combination computational prediction empirical data analysis. then nucleotide diversity allele...
