Raw genotyped total called structural variant (SV)

Kittikun Songsomboon, Zachary Brenton, James Heuser, Stephen Kresovich, Nadia Shakoor & Elizabeth Cooper
Genomic structural mutations especially deletion are an important source of variation in many species and can play key roles in phenotypic diversification and evolution. Previous work in many plant species, including some crops, has identified multiple instances of structural variations (SVs) occurring in or near genes related to stress response and disease resistance, suggesting a possible role for SVs in local adaptation. Sorghum (Sorghum bicolor (L.) Moench) is one of the most widely grown cereal...

Molecular systematics of the tribe Physarieae (Brassicaceae) based on the nuclear ITS, Luminidependens, and chloroplast ndhF: Sequence alignments, trees, and supplemental figures

Sara Fuentes-Soriano & Elizabeth Kellogg
Physarieae is a small tribe of herbaceous annual and woody perennial mustards that are mostly endemic to North America, with its members including a large amount of variation in floral, fruit and chromosomal variation. Building on a previous study of Physarieae based on morphology and ndhF plastid DNA, we reconstructed the evolutionary history of the tribe using new sequence data from two nuclear markers, and compared the new topologies against previously published cpDNA-based phylogenetic hypotheses....

Replaying the evolutionary tape to investigate subgenome dominance in allopolyploid Brassica napus

Kevin Bird, Chad Niederhuth, Shujun Ou, Malia Gehan, J. Chris Pires, Zhiyong Xiong, Robert VanBuren & Patrick Edger
Interspecific hybridization and allopolyploidization merge evolutionarily distinct parental genomes (subgenomes) into a single nucleus. A frequent observation is that one subgenome is "dominant” over the other subgenome, having a greater number of retained genes and being more highly expressed. Which subgenome becomes dominantly expressed in allopolyploids remains poorly understood. Here we “replayed the evolutionary tape” with six isogenic resynthesized Brassica napus (rapeseed) allopolyploid lines and investigated subgenome dominance patterns over the first ten generations post...

Correlation and co-localization of QTLs for stomatal density, canopy temperature, and productivity with and without drought stress in Setaria

Parthiban Thathapalli Prakash, Darshi Banan, Rachel Paul, Maximilian Feldman, Dan Xie, Luke Freyfogle, Ivan Baxter & Andrew Leakey
Mechanistic modeling indicates that stomatal conductance could be reduced to improve water use efficiency (WUE) in C4 crops. Genetic variation in stomatal density and canopy temperature was evaluated in the model C4 genus, Setaria. Recombinant inbred lines (RILs) derived from a Setaria italica × Setaria viridis cross were grown with ample or limiting water supply under field conditions in Illinois. An optical profilometer was used to rapidly assess stomatal patterning, and canopy temperature was measured...
