【摘要】 在进行矮牵牛(Petunia bybrida)光周期诱导开花的过程中,对叶子中的可溶性蛋白质进行了分析,其中有4条与开花有关的特异蛋白,分子量分别为49.45 kD(a)、35.45 kD(b)、17.98 kD(c)和11.74 kD(d)。在不开放的花苞中不含有蛋白质a和d,只有这4种蛋白质全出现时,才能形成花苞并且开放。花开了以后,蛋白质c和d就消失。即使在开花的植株中,各组织中的蛋白质 也是不同的。茎中完全不含有蛋白质c和d,叶子和花中的蛋白质组成也是不同的。更多还原

【Abstract】 Soluble proteins were extracted from the leaves of Petunia hybrida when flower differentiation was induced. The results showed that 4 special proteins, with molecular weight of 49.45 kD(a), 35.45 kD(b), 17.98 kD(c) and 11.74 kD(d), are related to blossoming of flowers after photoperiod induction. Without proteins a and d only floral buds were formed which were never blossomed. There were flowers when all the 4 special proteins appeared together. Proteins c and d disappeared after blossoming. Proteins in different tissues were different when the plant was induced to blossom. Thus, for example, protein c and d were absent from stem throughout the process.更多还原
