This study examines how genetic architecture of flowering time in Arabidopsis thaliana changes between overwintering environments and growth chambers, finding extensive gene-by-environment interaction and environment-specific genetic effects.

The paper identifies a rare deletion in IhUF3GT1 causing anthocyanin loss in ivy-leaf morning glory, confirming its role in pigmentation.

The paper identifies a 117 kb indel associated with leaf shape polymorphism in Ipomoea hederacea and shows it is a novel genetic mechanism distinct from related species.

The paper develops a high-throughput assay to measure cold tolerance in C. elegans and finds that 24-hour cold exposure increases variation and heritability of cold tolerance during the L1 larval stage.

This study identifies multiple developmental defects in hybrids of Caenorhabditis species that contribute to postzygotic reproductive isolation, but finds no evidence of premating isolation or ectopic sperm migration as barriers.
