Abstract: Pollen wall plays vital role during microspore development and pollination in rice(Oryza Japonica). Abnormal pollen wall formation usually leads to male sterility. Callose wall,microspore primary wall development and sporonpollenin accumulation are key step to control pollen wall formation. Recent studies focus on callose wall formation during microspore development. Neither less,the knowledge about monosaccharide composition in the pollen wall is limited. In this study,we compared the monosaccharide composition in the pollen wall of the wide type rice with a male sterility mutant gsl5.

Key words: rice, male sterility mutant, gsl5, monosaccharide composition
