摘要: Plant senescence plays diverse important roles in development and environmental responses. However, the molecular basis of plant senescence is remained largely unknown. A rice spontaneous mutant with the character of early senescence and male sterility (sins) was found in the breeding line NT10-748. In order to identify the gene SMS1 and the underlying mechanism, we preliminarily analyzed physiological and biochemical phenotypes of the mutant. The mutant contained lower chlorophyll content compared with the wild type control and was severe male sterile with lower pollen viability. Genetic analysis showed that the mutant was controlled by a single recessive gene. By the map-based cloning approach, we fine-mapped SMS1 to a 67 kb region between the markers Z3-4 and Z1-1 on chromosome 8 using 1,074 F(2) recessive plants derived from the cross between the mutant sms1 (japonica) x Zhenshan 97 (indica), where no known gene involved in senescence or male sterility has been identified. Therefore the SMS1 gene will be a novel gene that regulates the two developmental processes. The further cloning and functional analysis of the SMS1 gene is under way.
