摘要: 利用SSH技术构建了喜旱莲子草雌雄同花和雄蕊心皮化花序的正反向基因表达的cDNA文库. 对文库部分克隆分析发现,EST功能涉及花性别发育、细胞代谢、生长发育、抗性适应、转录调控、酶调节、叶绿体和胞质基因、细胞内组件等8种不同功能类型.共筛选到8类与已知调控花性别发育相关的EST,如HD基因家族、MADS-box基因家族、线粒体基因、CCLS4家族蛋白等.

Abstract: Functions of the SSH cDNA library of two different inflorescences of hermaphrodite and pistillate of Alternanthera philoxeroides were sorted into eight different categories, involving the development of sex differentiation of flowers, the process of metabolism, cytoplasmic gene etc. Sex differentiation ESTs point to eight kinds of gene families, including homeobox ZIP, MADS-box, CCLS4 protein family, mitochondria male-fertile, and cytoplasmic male-sterility genes.

Key words: Alternanthera philoxeroides, stamen-pistillody, SSH library, EST analysis
