Divergent genetic architecture of cold stress tolerance in <i>aus</i> and <i>tropical japonica</i> rice.

ABSTRACT:

Introduction

Exploring natural genetic variation to facilitate breeding of improved rice seedling cold tolerance will allow the crop to be planted earlier in the growing season, taking advantage of spring rainfall and decreasing exposure to high summer nighttime temperatures, which reduce grain quality.

Methods

To uncover genomic regions in rice that manage cold stress tolerance response mechanisms in the cold-sensitive aus (AUS) and the relatively cold-tolerant tropical japonica (TRJ) subpopulations, and to identify cold tolerance genes, AUS and TRJ recombinant inbred line populations developed from crosses between cold-tolerant and cold-sensitive parents were used for quantitative trait locus (QTL) mapping of two traits: degree of membrane damage after 1 week
