The expression patterns of soluble proteins , peroxidase and esterase isozymes were analysed on globular embryogenesis in tissue cultures of alfalfa , it was concluded that from embryogenic callus to globular embryo genesis h peptides emerged and disappeared orderly , the patterns of peroxidase isozyme changed dramatically , esterase isozymes changed slightly while the total enzyme activity was important to keeping the potential of somatic embryogenesis 摘要试验在苜蓿组织培养中,对球形胚形成过程中特异蛋白质表达的模式、过氧化物酶及酯酶同工酶酶谱变化进行研究,结果表明:苜蓿组织培养中从胚性愈伤组织到球形胚发育的进程中,顺序消失和出现了11种中小分子量多肽;过氧化物酶同工酶酶谱发生了显著的变化;酯酶同工酶酶谱变化不大,但其总活力对于维持体细胞胚胎发生是必须的。
