【Abstract】 The activities and the zymograms of Ca 2+ /CaM dependent protein kinase(Ca 2+ /CaM PK) were studied in the leaves of Hubei Photoperiod sensitive Genic Male sterile Rice Nongken 58S(HPGMR 58S) at the stage of first branch perimordium(Ⅱ) and the stage of the formation of pollen mother cell(Ⅵ) with different photoperiod inductions.The results showed that the Ca 2+ /CaM PK activites appeared to be a change from a low to high level as developing young pancile.Furthermore,the enzyme activites in leaves of 58S were clearly higher in LD and ND than that in SD at the Ⅵ stage.The bands of the zymograms were no significant differece, but only the bands were clearly stronger in SD than in LD and ND.更多还原
