Abstract

The DNA marker associated with cold tolerance was cloned from random amplified polymorphic DNA (RAPD) fragments amplified with genomic DNA of a rice cultivar, Dular. The nucleotide sequence revealed that the putative open reading frame was 511 base pairs and contained 169 amino acid residues. It is 79% and 57% identical to the rice cDNA (C26347) found in the GeneBank Database at the nucleotide and amino acid sequence levels, respectively. Through RAPD analysis for the cold tolerance of 94 F2 plants from a cross between Dular (indica, cold-sensitive cultivar) and Toyohatamochi (japonica, coldtolerant cultivar), OPT8511 was confirmed to have strong association with cold tolerance of rice. The clone OPT8511 was amplified from polymerase chain reaction of genomic DNA in 21 rice cultivars by custom-made primer. This marker could be of use in marker-assisted selection for cold tolerance in rice.
