摘　　要：水稻叶形与产量关系密切。水稻叶形可以解析为叶片长、宽、厚、叶面积、叶片卷曲和叶片直立性。目前通过对水稻分离群体及突变体的研究,已定位和克隆到多个叶形基因/QTLs。为此,本文综述叶形相关基因定位、克隆与功能分析研究进展,总结叶片卷曲和直立性形成的分子机制,并阐明已定位的基因/QTLs与产量的关系。Leaf architecture, which plays important role on determining grain yield potential in rice, was characterized as leaf length, leaf width, leaf thinness, leaf area, leaf rolling and leaf erect ability. Recently, significant progress has been made in mapping and isolating leaf architecture related QTLs and genes by studies for segregating populations and mutants. This review, therefore, aims to summarize the progress on mapping and cloning genes related to leaf architecture, understanding of their function and trying to elucidate their association with grain yield. The molecular mechanism about formation of leaf rolling and erect ability was also discussed.
