| 摘 要： | 内切多聚半乳糖醛酸酶（endo-polygalacturonase，endo-PG）是待异水解细胞壁成分多聚半乳糖醛酸的酶，水解产生的10～13个糖基的寡聚半乳糖醛酸片段是活性诱导因子，激活植物自身防御系统．我们已研究发现单子叶植物小麦中存在多聚半乳糖醛酸酶抑制蛋白（polygalacturonaseinhibitingprotein，PGIP），并已将其分离纯化，对其性质作了初步研究1,2]文献报导3]PGIP是在未分化的细胞中合成的．本文报导在悬浮培养的小麦细胞中加入Endo-PG观察其PGIP的生成，比较赤霉病的高抗品种与低抗品种中PGIP的合成情况，探讨PGIP与植物防御作…

| Abstract: | The activity of polygalacturonase inhibiting protein (PGIP)was assayed in four kind of cultures induced endo-polygalacturonase (endo-PG). It was discovered that endo-PG stimulated obviously the accumulation of PGIP. The PGIP contents of SuMai No. 3 and SA-Ⅱ cells,which are fungal disease-resistant,are higher than the contents of Mian Yang No. 11 and JingHua No.1. It is indicated in cell level that PGIP has relation to resistance of plant. |
