The stamens and pistil of d . versipelis mature before the flowers open , which shows that dysosma versipelis may be autogamous . d . versipelis produce few fruits . ovaries of d . versipelis seldom develop in nature , but will develop after being pollinated with pollen of another plant 八角莲的花在花苞未展开时，雄蕊和雌蕊便已成熟，说明八角莲的繁育系统为自花受粉，八角莲座果率非常低，自然状态下，子房不膨大，人工异交后的子房有膨大现象，说明八角莲自交低育，有生殖障碍。

Here we found g proteins also function in leaf , silique development and the yield of pollen microspore . we observed several traits or characters in the offsprings of gpal , agbl null mutation and gpa1 overexpression lines and found that the width of mutants " lamina is larger than that of the wild type , whereas the lamina length , petiole length and rosette diameter is smaller than the wild type , the ga overexpression lines is different from the mutants ; the silique length and the pedicel length is larger in mutants than that of wild type , and slightly smaller in overexpression lines than the control ; the morphometric character in silique tip is different in gpal from agbl mutants ; the yield of pollen microspore is larger in null mutants than wild type whereas smaller in overexpression lines 实验中我们跟踪观察了多代异三聚体g蛋白a亚基超表达转基因植株及a ， p亚基缺失突变体的表型特征，发现突变体的叶片宽度大于对应的野生型，叶片长度，叶柄长度及莲座直径小于野生型，而超表达植株的上述某些特征与突变体相反; gp时突变体的长角果长度，花梗柄部长度大于野生型，而超表达ga植株种英则略小于对照; gpal突变体长角果尖端未出现咭乙i突变体的特征: gpal ，口gbl突变体花粉生成量大于野生型，而超表达ga植株的花粉生成量则略小于对照。

The future characterization and genetic analysis for candidate mutant were carried out and find that some candidate mutant ( such as roi30 doil - 1 doi0311131 ) have good phenotype by drought h2o2 aba - stressed treatment . at the same time we also observe the development of candidate mutant at different growth stages carefully . many modal difference between mutant an d wild type at the same period were found , such as more rosette layering fatty and big in leaves , advancment or delay for the flower period , rosettes living in the main stem , shorten in figure , the amount of seed little , sterilization etc . these physiological and modal changes may reflect with maladjustment in expressions of some gene and confusion on their inner control , . we will futher study concrete and detailed function mechanism 我们对这些拟南芥侯选突变体进行进一步的鉴定和遗传学分析，发现ro口口、 doil 、 doi口jlll3i等潜在突变株对aba 、过氧化氢及早胁迫有明显表型，同时对潜在突变体的生长发育进行了详细的观察，发现多数潜在突变株与同条件下野生型比出现了许多明显的形态改变，如:莲座基叶增多、分层、肥大，花期提前或延迟，主茎生轮座，株型矮化，产籽量少，不育，败育等，这些生理和形态上的差异很可能反映了它们内部某些基因的表达受到了影响、代谢调控发生了紊乱，具体和详细的作用机制还需要进一步的研究。
