In this study, 105 TDFs were in silico mapped in the rice high-density linkage map. Nineteen TDFs were mapped to the quantitative trait loci regions for root growth under water-limited conditions in, at least, two of three rice populations derived from three crosses with the same parent of Azucena (Bala×Azucena, IR64×Azucena and IR1552×Azucena). Four of 19 genes (T37, L16, T17 and T7) were mapped based a RIL population of IR1552×Azucena by southern blot analysis. Five genes encode putative or hypothetical protein. Other 14 genes were similar with known genes in databases including expansin (OsEXP2), late embryogenesis-abundant gene , an SR-related protein essential for spliceosome assembly (SART1), autophagocytosis protein , bHLH protein, fruit-ripening protein similar to ASR, nickel-binding protein 2A, DNA-binding protein, pyruvate dehydrogenase kinase , stomatin-like protein, SR1 induced by sucrose starvation, vacuolar protein sorting protein (VSP33a), gibberellin action negative regulator and retroelement.
