水稻温敏叶绿素突变体叶片超微结构的研究

Study on Leaf Ultrastructure of the Thermo-sensitive Chlorophyll Deficient Mutant in Rice

  • 摘要: 对温敏转绿型叶绿素突变体1103S和武金4B"斑马叶"性状表达过程中叶绿素含量、叶绿体超微结构的变化进行了比较研究。结果表明,在一定条件下,叶片的失绿、复绿与叶绿素含量的下降、上升变化趋势一致;叶绿体结构在失绿区表现为严重退化,基粒和基粒片层减少,淀粉粒和嗜锇粒增多;复绿后,其叶绿体结构重建和恢复。

     

    Abstract: The changes of chlorophyll content and chlor oplast ultrastructure were studied during the period of appearing zebra-leaf ch aracter from the thermo-sensitive chlorophyll deficient mutants of rice 1103S a nd Wujin 4B.The results shown that content of chlorophyll decreased after appeari ng zebra-leaf character.Ultrastructural changes occurred in the chloroplasts in the yellow part including grana lamellae and grana decreasing and significant a ccumulation of starch grains and osmiophilic globules.However,the chloroplast structure renewed and restructured normally after recovery of the yellow part of leaves into green.
