Abstract

The acyl-lipid composition of a barley mutant that contained no detectable chlorophyll b was studied. This mutant contained chloroplasts that were much less organized than chloroplasts of normal barley. The mutant contained all the normal acyl lipids, with small increases in the relative concentration of phosphatidylglycerol and diacylsulphoquinoglycerides was unchanged, but most other lipids of the mutant barley contained lower amounts of alpha-linolenic acid compared with normal. There was no difference in the transhexadec-3-enoic acid content of phosphatidylglycerol, which was evidence against this lipid being involved in grana stacking.

摘要

对一个不含可检测到的叶绿素b的大麦突变体的酰基脂质组成进行了研究。该突变体含有比正常大麦叶绿体组织程度低得多的叶绿体。该突变体含有所有正常的酰基脂质,磷脂酰甘油和二酰基磺基喹啉甘油酯的相对浓度略有增加,而二酰基磺基喹啉甘油酯未发生变化,但与正常大麦相比,突变体大麦的大多数其他脂质中α-亚麻酸的含量较低。磷脂酰甘油的反式十六碳-3-烯酸含量没有差异,这证明该脂质不参与基粒堆积。
