摘要： A dynamically rolled leaf mutant (rl10) was identified from a spontaneous mutation in an Oryza sativa L. subsp. indica line, II-32B. The leaf chlorophyll content of rl10 is higher than that of the wild type. Genetic analysis using 3 F-2 segregating populations derived from crosses between rl10 and the rice lines Mian5B, II-32B, and D62B, respectively, confirmed that the rolled leaf trait of rl10 is controlled by a single recessive gene. Of 719 SSR primer pairs that showed polymorphism between D62B and rl10, 151 were adopted to map the RL10(t) gene using an F-2 segregating population of the cross rl10 x D62B, which contained 352 recessive plants. RL10(t) was primarily mapped on the long arm of chromosome 9, 5.09 cM from marker RM105 and 5.13 cM from marker RM3912. Using a novel set of 22 primer pairs between RM105 and RM3912, RL10(t) was further mapped between markers rlc3 (0.72 cM in distance) and rlc12 (0.1 cM in distance) using an F-2/F-3 Population containing 1172 recessive individuals. Mapped position analysis and homology analysis of the 20 genes within the 194-kb region between these 2 markers both indicated that a gene encoding a Myb-like domain transcription factor with homology to Arabidopsis KANADI (annotated in PAC clone AP005904) is the most probable candidate for RL10(t). This study enables further investigation of whether KANADI-like Myb genes are involved in leaf polarity modeling in monocots, as they are in dicots.
