| 摘 要： | 比较研究几种兼性和专一性ＣＡＭ植物材料的ＰＥＰＣ同工酶表明：经自然干旱诱导，兼性ＣＡＭ植物露花（Ｍｅｓｅｍｂｒｙａｎｔｈｅｍｕｍｃｏｒｄｉｆｏｌｉｕｍ）、长药景天（Ｓｕｄｕｍｓｐｅｃｔａｂｉｌｅ）有新的ＰＥＰＣ同工酶的出现，诱导前后各同工酶的天然分子量变化不大；而土三七（Ｓｅｄｕｍａｉｚｏｏｎ）则没有新的ＰＥＰＣ同工酶出现，但诱导后其同工酶的天然分子量有所增大。以上几种兼性ＣＡＭ植物的ＰＥＰＣ同工酶酶谱无明显昼夜变化。专一性ＣＡＭ植物的ＰＥＰＣ酶谱和天然分子量均较一致，亦无昼夜差异。

| Abstract: | By comparison research of PFP carboxylase in the facultative and obligate CAM plants, it is showed that there is new PEPC isozyme appearence from M. cordifolium and S. spectabile by drought induction. But it does not appearence from S. aizoon. It is not obvious that the daytime-night vairety of PEPC isozyme from several facultative CAM plants- The bands of PEPC isozyme are alike from obligate CAM plants. It is also not diferent in daytime and night. |
