| 摘要: |
| 在田间选育系谱过程中发现了一份黄绿叶突变体ygl-m ,该突变体叶片在苗期自发地表现黄绿色,待植株长到6周大左右植株叶片开始恢复绿色,最后整个植株叶片都恢复正常的绿色。苗期ygl-m 与野生型植株B73相比,叶片总叶绿素、叶绿素a、叶绿素b含量均显著下降,叶绿素a/b比值显著升高；苗期叶片叶绿体中基粒类囊体片层较少,排列不规则,结构松散。遗传分析表明,突变体ygl-m 的黄绿叶表型由隐性单基因控制。本研究将为开展ygl-m 基因的分子标记定位和进一步探讨其利用潜力奠定基础。 |

| Abstract: |
| A yellow-green leaf mutant ygl-m was identified in the process of pedigree selection in field, which spontaneously showed yellow-green leaf phenotype at seedling stage.The plants began to restore green in almost 6 weeks later,and then all leaves of the plants turned green. Compared to wild type line B73, the contents of total chlorophyll, chlorophyll a, chlorophyll bin ygl-m decreased significantly, while the ratio of chlorophyll a/bincreased significantly.There are only of few chloroplast grana thylakoid lamellar with irregular arrangement and loose structure in ygl-m at seedling stage. Genetic analysis showed that a single recessive gene controlled the yellow-green leaf phenotype of ygl-m .This study may lay foundations to molecular map of ygl-m and further explore its application of potential. |
