A novel functional gene associated with cold tolerance at the seedling stage in rice.

ABSTRACT: Identification and cloning of cold-tolerant genes that can stably express under different cold environments are crucial for molecular rice breeding for cold tolerance. In the previous study, we identified a cold-tolerant QTL at the seedling stage, qCTS-9 which could be detected under different cold environments using a recombinant inbred line (RIL) population derived from a cold-tolerant variety Lijiangxintuanheigu (LTH) and a cold-sensitive variety Shanhuangzhan 2 (SHZ-2). In this study, eight candidate genes within the qCTS-9 interval were identified through integrated analysis of QTL mapping with genomewide differential expression profiling of LTH. The qRT-PCR assay showed that only Os09g0410300 exhibited different expression patterns between LTH and SHZ-2 during cold stress, and signif
