The major target of photoinhibition is photosystem ii ( psii ) on which photoinhibition make photosynthetic efficiency decreased , electronic transportation blocked and reaction center protein dl photodamaged 已有研究表明ps是主要靶点,光抑制时表现为: ps光合效率下降、 ps电子传递链活性下降及核心蛋白被氧化而破坏。

Under freezing conditions , n . commune deactivated the photosystem ( ps ) ii activity , which may protect the cells from photoinactivation . light energy absorbed by psii complexes was also dissipated to heat energy 在冻结条件下, nostoccommune的ps活性失活, ps复合体吸收的光能转化为热能耗散,由此保护了细胞免受光抑制的伤害。

The study on the function and mechanism of phrip1 is important for clarifying how the cell plate and cell wall form in plants . in this study , full length of phrip1 is amplified by pcr and ligated into pks plasmid , then the bait plasmid , peg202 - phrip1 , is constructed . the inseret gene are sure to be translated into the right fusion protein through its sequence . in the yeast two - hybrid system , the bait plasmid ( peg202 - phrip1 ) and a reporter plasmid ( psh18 - 34 ) are introduced into the yeast ( egy48 ) by co - transformation . then cdna library ( which is in pjg4 - 5 ) is screened and two genes are obtained . the two insert gene fragments are sequenced . one of them is plastocyanin , the other is putative photosystem i reaction center subunit ii precursor , both of them are the necessary components of photosynthetic chain 成膜素相关蛋白1 ( phrip1 )是一个含608个氨基酸的蛋白质,它对于植物胞质分裂中细胞板的形成起到了十分重要的作用。研究phrip1的功能和机制,对在分子水平上阐明植物细胞板以及细胞壁形成的机理具有重大的生物学意义。在本实验中,根据phrip1的序列设计引物对其进行pcr扩增,得到该基因后将其连接到了pks质粒上,并进一步构建成了诱饵质粒peg202 - phrip1 。

The electron transport rates of chloroplasts were depressed after chinese cabbage and mustard had been infected with tumv , whose extents reached 6 . 4 % and 64 . 6 % respectively . the decline of photosystem ii ( psii ) activities mainly contributed to the drop of electron transport rate , whose degrees reached 56 . 9 % and 34 . 3 % , with the statistical result p < 0 . 01 青菜和芥菜叶绿体电子传递全链的电子传递速率各降低6 . 4和64 . 6 ;光系统( ps )的电子传递活性各下降56 . 9和34 . 3 ,与健康对照的差异水平均达到极显著;光系统( ps )的电子传递受抑程度较轻,分别为25 . 8和24 . 7 。

Chloroplast studies in vitro indicate that the choloplast shsp are related to the thylakoid membranes in response to heat stress . when the proteins are induced , the increase of their expresstion is positively correlated with ps ii ( photosystem ii ) thermotolerance and the whole - plant thermotolerance . in plants , active oxygen species are inevitably generated during photosynthe - sis , and the major site of generation of these toxic species is the chloroplast under both unstressed and stressed conditions . lt has been recognized that the chloroplast shsp have protective functions against oxidative stress , and this functions are corr - elated with its unique met - rich domain 当诱导产生叶绿体shsp时,其表达量的增加与ps ( photosystcm )耐热性的增强以及整株植物耐热性的增强密切相关。另外,叶绿体是有害的活性氧产生的活跃部位,在氧化胁迫条件下,叶绿体shsp对细胞起到重要的保护作用。而这个保护作用与叶绿体shsp的甲硫氨酸富含区有关。
