photosystem 解釋
光電系統
  1. In photosynthesis ferredoxin is involved in electron transfer between photosystem i and the final electron acceptor, nadp

    在光合作用中，鐵硫蛋白與光合系統和最終電子受體nadp間的電子傳遞有關。
  2. Studies of photosystem complexes and chlorophyll synthesis in chlorophyll - deficient rice mutant w

    葉綠素缺乏大麥突變體的生理與遺傳研究
  3. 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是主要靶點，光抑制時表現為： ps光合效率下降、 ps電子傳遞鏈活性下降及核心蛋白被氧化而破壞。
  4. 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

    成膜素相關蛋白1 （ phrip1 ）是一個含608個氨基酸的蛋白質，它對于植物胞質分裂中細胞板的形成起到了十分重要的作用。研究phrip1的功能和機制，對在分子水平上闡明植物細胞板以及細胞壁形成的機理具有重大的生物學意義。在本實驗中，根據phrip1的序列設計引物對其進行pcr擴增，得到該基因后將其連接到了pks質粒上，並進一步構建成了誘餌質粒peg202 - phrip1 。
  5. 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

    青菜和芥菜葉綠體電子傳遞全鏈的電子傳遞速率各降低6 . 4和64 . 6 ；光系統（ ps ）的電子傳遞活性各下降56 . 9和34 . 3 ，與健康對照的差異水平均達到極顯著；光系統（ ps ）的電子傳遞受抑程度較輕，分別為25 . 8和24 . 7 。
  6. 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

    當誘導產生葉綠體shsp時，其表達量的增加與ps （ photosystcm ）耐熱性的增強以及整株植物耐熱性的增強密切相關。另外，葉綠體是有害的活性氧產生的活躍部位，在氧化脅迫條件下，葉綠體shsp對細胞起到重要的保護作用。而這個保護作用與葉綠體shsp的甲硫氨酸富含區有關。
  7. Nowadays, the reported proteases in thykaloids include the energy - enzyme and non - energy - enzyme. they are almost all involved in the processing and degradation of proteins in lumen or membrane of thykaloid [ 12 - 18 ]. in our lab, some proteases associated with photosystem ii of spinach have been discovered in years

    我們實驗室多年來致力於光系統結合蛋白酶的分離純化與性質研究工作，已經取得了一定的成績，分離得到了幾種光系統結合的蛋白酶，這些蛋白酶的性質有著較大的差異，而且也不同於國內外已經報道過的光系統結合蛋白酶。
  8. 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

    在凍結條件下， nostoccommune的ps活性失活， ps復合體吸收的光能轉化為熱能耗散，由此保護了細胞免受光抑制的傷害。
  9. Photosystem of higher plants. the compositions of glycerolipids and fatty acids in the

    復合物的類脂及脂肪酸組成
