Genetics of chilling response at early growth stage in rice: a recessive gene for tolerance and importance of acclimation.

ABSTRACT: Low-temperature adaptation in rice is mediated by the ability of a genotype to tolerate chilling temperatures. A genetic locus on chromosome 11 was analysed for chilling tolerance at the plumule stage in rice. The tolerant allele of A58, a japonica landrace in Japan, was inherited as a recessive gene (ctp-1^A58), whereas the susceptible alleles from wild rice (Ctp-1^W107) and modern variety (Ctp-1^HY) were the dominant genes. Another recessive tolerant allele (ctp-1^Silewah) was found in a tropical japonica variety (Silewah). Fine-mapping revealed that a candidate gene for the ctp-1 locus encoded a protein similar to the nucleotide-binding domain and leucine-rich repeat (NLR) protein, in which frameshi
