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.

Census of Crow Pheasant was conducted in Guangdong Haifeng Avian Nature Reserve in 2005. Among four seasons, there were thirty two individuals recorded in summer which was the most. The mean-individual of each line in summer was significantly higher than that in spring and autumn (P.05). The population density in summer was the highest, 17.78 ind./km^2 vs. 1.11 ind./km^2 in winter which was the lowest.
