Natural variation of indels in the CTB3 promoter confers cold tolerance in japonica rice
Abstract Improvement of cold tolerance at the booting stage (CTB) in rice is a key strategy for cultivation in high-altitude and high-latitude regions.Here, we identify CTB3 Storage/Laundry Basket gene, encoding a calmodulin-binding transcriptional activator that positively regulates cold tolerance at the booting stage in japonica rice.Two indels (
