We also analyzed their Ca 2+ \|ATPase isozymogram. It was found that the Ca 2+ \|ATPase activity of the organelles provided for study were higher under LD treatment than under SD treatment at different stage, their Ca 2+ \|ATPase isozymogram also showed Nongken58S under LD treatment had one more band than those under LD treatment. The activity of nucleus Mg 2+ \|ATPase was higher under SD treatment, too; Mitochondria Mg 2+ \|ATPase changed differently under SD and LD treatment .All Those difference indicated that the ATPase of different cell organelles had their own function and they may have close relationship with the fertility transformation of Nongken58S. 农垦58S Mg2+-ATPase Ca2+-APTase 叶绿体 线粒体 10.14188/j.1671-8836.2000.06.025 Q946;Q945.4 国家自然科学基金资助课题! （ 3 93 70 42 7） 2000-06-01 2021-04-01 6
