| Research Abstract |
To elucidate the mechanism of sex differentiation of cucumber (Cucumis sativus L.) plants, expression of programmed cell death (PCD) related gene, MMP gene, and seven cell-cycle-related genes (CsCycA, CsCycB, CsCYD3:1, CsCYD3:2, CsCDKA, CsCDKB, CsCYR) was analyzed in both male and female flower buds. MMP gene expressed at the region where pistil primorida arrested in male flower buds and at the region where stamen primordia arrested in female flower buds. CsCYR, CsCycA, CsCycB, CsCYD3:2 genes expressed at the region where stamen primordia arrested in female flower buds. It is possible that acceleration of cell cycle and PCD are involved in the inhibition of stamen development in female flower buds of cucumber.
