Reversing anther thermotolerance by manipulating the cis-elements in the promoter of a high-temperature upregulated gene Casein Kinase I in upland cotton.

Abstract excerpt

High temperature (HT) stress causes male sterility, leading to reduced upland cotton yield. Previously, we identified a key gene, Casein Kinase I (GhCKI), that negatively regulates male fertility in upland cotton under HT. However, conventional genetic manipulations of GhCKI would result in male sterility, hindering its utilization in breeding programs. Here, we engineered quantitative variation for anther...
