摘要
对苦瓜（ＭｏｍｏｒｄｉｃａｃｈａｒａｎｔｉａＬ．）的两性期和雌、雄花早期发育过程中的３个时期花蕾，用毛细管电泳法进行可溶性蛋白质分析，发现了一些与性别分化有关的特异蛋白质。其中１１ｋＤ的蛋白质从幼雌花时期开始出现后，在雌花发育的３个典型时期都存在，很可能是雌花分化程序表达中的一种“关键蛋白”。与之类似，３０ｋＤ的蛋白质很可能是雄花程序表达中的一种“关键蛋白”
In Momordica charantia L. the soluble protein profile of flower bud at hermaphroditic stage and three early developmental stages (the 7th,10th and 13th day after initial budding) of male and female flowers were analysed with capillary electrophoresis. Some specific proteins related to sex differentiation were detected. The 11 kD protein,which appeared at the 7th day of budding and existed through the three developmental stages of the female flowers with little change of content,might be an “essential protein” for the expression of female flower differentiation program. Similarly, the 30 kD protein might be an “essential protein” for the expression of the male flower differentiation.
