在水稻中鉴定出1个Es-t突变体,该突变体是用甲基磺酸乙二醇盐处理日本晴菌株产生的。ES-t的叶片在苗期出现黄化,并降低了叶绿素含量。ES-T在生长过程中发现锈斑,尤其是在叶缘和叶尖。植株在乳熟期表现出典型的早衰表型。在扫描电子显微镜下,ES-t的叶片表面比野生型叶片更光滑,这是因为叶片气孔周围没有硅质突起。在ES-T中,叶绿体生长异常,充满大量淀粉粒。石蜡切片分析表明,ES-T的厚壁组织细胞和维管束的发育也异常。遗传分析表明,Es-t是由一对隐性基因控制的,该基因被精确定位在5号染色体上42 kb的区间内。这些结果为该基因的定位克隆和功能研究奠定了基础。
An es-t (early senescence-temporary) mutant, produced by ethylene methylsulfonate treatment of strain Nipponbare, was identified in rice. The leaves of es-t appeared yellow at the seedling stage, and had decreased chlorophyll content. Rust spots were found during growth in es-t, especially at the leaf margin and tip. The plants showed a typical early-senescence phenotype at the milky stage. The leaf surface of es-t appeared smoother than wild-type leaves under a scanning electron microscope, because the leaves lack siliceous protuberances around the stoma. Chloroplasts grow abnormally and are filled with many starch grains in es-t. Paraffin section analysis showed that the development of the sclerenchyma cells and vascular bundles were also abnormal in es-t. Genetic analysis indicated that es-t was controlled by a recessive gene, which was finely mapped to a 42-kb interval on chromosome 5. These results will facilitate the positional cloning and functional studies of the gene.
