Abstract excerpt

Chilling stress severely threatens rice productivity. While multiple signaling pathways in chilling tolerance have been elucidated, the role of the Mediator complex in this process remains poorly understood. Here, we identify COG5, a major quantitative trait locus (QTL) gene encoding the Mediator complex subunit Med21, as a positive regulator of chilling tolerance in rice. A promoter variation in COG5 leads to...
