A recent study published in Biological Diversity reveals that ecological selection drives population differentiation and local adaptation in Capsella bursa-pastoris, a widely distributed annual herb. Genome-wide scans identified 54 candidate genes under positive selection related to energy metabolism and other processes.

A research team has identified two distinct genetic lineages corresponding to low- and high-altitude habitats in Capsella bursa-pastoris. Genome-wide scans detected 54 candidate genes under positive selection, highlighting temperature seasonality and precipitation as key drivers of adaptive divergence.

Salk Institute scientists created a high-resolution atlas showing how droughts affect plant cells. They identified a gene, Ferric Reduction Oxidase 6 (FRO6), that could be targeted to create more resilient crops. FRO6 expression in mesophyll cells partially maintained leaf growth under drought stress.
Researchers found that the plant aborts almost all fruits containing larvae, but instead allows larvae to emerge and burrow into soil, promoting a stable balance in the relationship. This 'fallen-fruit compromise' is a novel mechanism that stabilizes nursery pollination mutualism between Sambucus and kateretid beetles.
