禾本科植物无融合生殖(综述)

APOMIXIS IN THE GRAMINEAE

摘要:

禾本科植物包含了世界上最重要的农作物，也包含了最多的无融合生殖的种类。通过无融合生殖可将农作物的F₁代杂种优势固定下来，这在固定农作物杂种优势的利用上具有巨大的潜力。然而禾本科植物无融合生殖作为其繁殖多样性的一种形式，在系统进化过程中的作用是非常复杂的。本文统计了禾本科无融合生殖的分布，概述了其无融合生殖的细胞学、遗传学和分子生物学研究进展。

Abstract:

Gramineae is one of the largest families with widest distribution on the globe. It contains most important crops in the world including a great number of apomictic species. Apomixis has great potentialities for utilization of crop hybrid vigor. However, apomixis as a reproductive way of diversity in plant revolution is very comprehensive. In this paper, the distribution of apomictic species in Gramineae is reviewed. Advance in studies on apomixes in aspects of cytology, genetics and molecular biology are also summarized.
