Compared with other CMS plants, the molecular basis of CMS rice is very unclearer, especially for those having been extensively used in hybrid breeding of China. So here, a serial molecular techniques are adopted to study the molecular basis of HongLian tylp CMS rice, taking sterile line , maintainer line , and hybrid F〓 HL No.

针对国内几种大面积推广的CMS水稻分子基础研究相对比较落后的状况，本文以水稻红莲型粤泰细胞质雄性不育系A和保持系B及杂种一代F〓为材料，运用一系列分子生物学技术和方法着重研究了红莲型水稻CMS的分子基础。

The results showed that the varieties and activity of POD isoenzyme expression exist in difference in anther of male sterility line and maintainer in different development stage in sweet pepper and hot pepper. POD isozyme activity of anther was very low in meiosis stage in male sterility line of sweet pepper. There is a POD special band in meiosis and pollen mature stage in male sterility line of pepper respectively.

结果表明不育系与保持系，在花药发育的不同时期POD同工酶表达种类及表达活性之间存在差异，其中甜椒不育系在减数分裂期POD同工酶的活性非常低，辣椒雄性不育系在减数分裂期及花粉成熟期分别多一条POD特征带。

However, the genetic differences of maintainer lines and the seventh restorers will be further studied by molecular technique.

然而，对于保持系和第7类恢复系而言，需借助分子手段进行研究以进一步了解其遗传差异。

The pectin esterase gene and amino acid permease gene abundantly expressed in floral buds of NCa CMS while pectin esterase gene showed no transcript either in young leaves of NCa CMS or in the two tissues of maintainer line, and amino acid permease gene slightly expressed in the corresponding tissues.

结果表明，果胶甲酯酶基因和氨基酸通透酶基因都在不育系花蕾中大量表达，果胶甲酯酶基因在不育系叶片、保持系的花蕾、叶片中都没有检测到；而氨基酸通透酶基因有微量表达。
