| 摘 要： | 从粳稻中花11组培后代中发现了一个苗期白条纹,抽穗期自穗的突变体.该突变体表现为1叶期叶全白,2叶期从新叶叶尖开始沿叶脉逐渐转绿,至成株期完全变绿,抽穗后内外颖表现为自色,穗轴和小枝梗表现为绿色,成熟后颖壳转黄.根据基因定位结果,将该突变体定名为wslwp(white striped leaf and white pa...

| Abstract: | A white striped leaf and white panicle mutant,designated as wslwp,was obtained from a rice(Oryza sativa L.ssp.japonica cv.Zhonghua 11) transfer DNA insertion mutant pool.The mutant was characterized by white leaves at the 1-leaf stage,chlorotic leaves with longitudinal green stripes at the 2-leaf stage,and green leaves before heading.Moreover,at the heading stage,the glume showed white color,but the panicle axis and rachis remained green.The grain changed into yellow at the maturity stage.Chlorophyll and ca... |
