Therefore, it is crucial to identify early senescent leaf mutants and then clone genes associated with senescence by map-based strategy, which is significant in the research of senescence mechanism. An early senescent leaf mutantesl5 has been discovered from the progeny ofindica restorer line Jinhui10 with seeds treated by ethylmethane sulfonate, this paper performed the studies on its morphological identification, cytological observation, physiological analysis and gene mapping. The results showed that theesl5 demonstrated normal phenotype at the seedling stage, displayed yellow green color at the tillering stage, and appeared yellow and senescent leaf blades at booting stage. Cell structure of theesl5 was badly influenced, showing destroyed cell membranes, loose and irregular stroma lamella in the section of senescent leaves. Chlorophyll content and photosynthetic rate of theesl5 were significantly lower than those of the wild type. Besides of the lower activities of SOD and CAT, the higher contents of ·OH and H2O2 were detected in theesl5 than in the wild type. The growth period ofesl5 delayed 20 days, grain number per panicle, filled-seed number and seed setting rate decreased significantly, but 1000-seed weight increased significantly at compared with the wild type. Genetic analysis suggested that the mutant trait was controlled by a recessive nuclear gene, and theESL5 was fine mapped on chromosome 3 between Indel markers Indel03-1 and Indel03-2 with 83.4 kb physical distance, containing 11 annotated genes. These results provide a foundation for the cloning ofESL5 by map-based strategy, which is essential in the research of senescence mechanism as well as molecular breeding inOryza sativa.
