Question

Rubisco
When tobacco Rubisco, covalently linked to CNBractivated Sepharose 4B, was treated with urea, the small subunit was dissociated at a urea concentration of 2–2.5 M, while the large subunit remained bound. When the urea concentration was lowered to 0.5 M, the dissociated small subunit could almost completely rebind (L.R. Li et al. 1988).Fructose 1,6-bisphosphate specifically protects the α-subunit of pyrophosphate-dependent6-phosphofructo-1-phosphotransferase against proteolytic degradation(Y.H. Wang and Shi 1999)。

Photoinhibition
Studies on the operation and regulation of the photosynthetic apparatus, started with the effects of humidity on the midday depression of photosynthesis (D.Q.Xu and Shen 1984). Study showed the relative contributions of different mechanisms in protecting the photosynthetic apparatus from photodamage during
leaf development (Hong et al. 1999). Under natural conditions, photoinhibition of photosynthesis in soybean can be attributed to reversible inactivation of PSII reaction centers, involving the dissociation of LHCII (Hong and Xu 1999). During photoinhibition, photodamage of histidine was discovered in PS II RC(Kuang et al. 1993). The photodamage of Pheo and P680 subsequently occurred: Pheo is first damaged under strong illumination; and a Pheo photo-protective scheme was proposed for PS II RC (Hou et al. 1996).In vivo studies demonstrated that PS II is rather resistant to water stress, as a mild water deficit in leaves did not significantly affect PS II activity. However,extreme water stress caused an obvious reduction in
photosynthetic O2 evolution (J.X. He et al. 1995). At moderate water stress, the apoproteins of LHC II decreased more rapidly than the Chl content. However,the contents of both Chl and apoproteins of LHCII decreased markedly in severely water-stressed maize leaves (Hao et al. 1996).Inhibition of D1 synthesis by treatment with lincomycin induced a parallel blockage on both zeaxanthin epoxidation and PS II recovery from a damaged state(C.C. Xu et al. 2000a). The role of the xanthophyll cycle in the protection against PS II photoinhibition
induced by chilling in moderate light was investigated,and it was suggested that the xanthophyll cycle might play a critical role in the protection of the thylakoid lumen against over-acidification and the resulting photoinhibition of PS II RC (C.C. Xu et al. 2000b).The xanthophyll cycle plays a role in protection of PS II from photoinhibition in senescent leaves by dissipating excess excitation energy, in particular when the leaves are exposed to high light levels (Lu et al.2001a, b). (See a historical account by B. Demmig Adams, this issue, for xanthophyll-dependent photo-protection by loss of heat.) H. Yu et al. (2000) demonstrated that LHC I was more sensitive than the PsaA/B subunits to degradation after 40 min illumination.

Rubisco 而大亚单位依然是区域， When烟草Rubisco，共价地连接与CNBractivated琼脂糖4B，对待了与尿素，小亚单位被离解了以2–2.5 M的尿素含量。 当尿素含量被降下了对0.5 M，被离解的小亚单位几乎完全地可能rebind (L.R.李等1988)。果糖1,6-bisphosphate specifically保护焦磷酸dependent6 phosphofructo 1 phosphotransferase α-subunit以防止蛋白水解的退化(Y.H. Wang和Shi 1999) 。Photosynthesis the research, the operation and the gauge head photosynthesis instrument, started with to affect the humidity to the midday rest photosynthesis (dqxu and Shen in 1984). The findings showed that the relative contribution different mechanism leaf develops (Hong Kong et al. in the protection photosynthesis instrument by the light in the . in 1999). Under the natural condition, photosynthesis's light suppresses in the soybean may attribute to the reversible deactivation the molecular field reaction center, involves dissociation lhcii (Hong Kong and Xu 1999). In the photosynthesis, the light ammonia acid is discovered in the second game of permanent secretary general (Kuang et al. in 1993). This light's pheo and p680 occurs afterward: pheo, first is under the destruction, intense illumination; With pheo the picture protection plan, proposed the second game of permanent secretary general (marquis et al. in 1996). Indicated in vivo research that second-level private secretary is the suitable anti-water stressed that takes temperate moisture content to owe lacks in the leaf blade not to have remarkable influence second-level private secretary to move. But, the violent moisture content coercion creates an obvious reduction, photosynthesizes the O2 evolution (Jiangxi, he waits for the human. in 1995). In the temperate moisture content coercion, carries the lipoprotein lhc second to fall is more rapid, compares Chile's content. However, content Chile and carries the lipoprotein lhcii obviously to fall, stressed in the serious water, corn leaf blade (Hao et al. in 1996). Suppresses D1 the synthesis treatment with Lin Kemei an element induction parallel clogging with silt, to bilateral maize yellow archery target epoxidation and the PS second recovery from a damage country (consumer council Xu et al. in 2000). The function, the xanthophyl circulation, is protecting to second-level private secretary photosynthesis the induction cicada is investigated in the temperate light, and some people believed that the xanthophyl circulation possible to play the crucial role, acidifies the light PS two regional exchange which excessively in the protection kind of pouch body cavity's opposition and produces from this (consumer council Xu et al. in 2000). In the xanthophyl circulation plays the role, in protection PS two, abates gradually from photosynthesis's senile leaf blade the surplus excitation energy, when particularly the leaf blade exposes in the high light level (al.2001a and so on Lu, b) funds. (sees a historical the account, by second grade demmig Adams, this question, the quantity of heat which loses for the xanthophyl dependence picture - protection. ) each hour jade et al. (in 2000) indicated that lhc I am more sensitive, after comparing psaa/the b Asia base degeneration, 40 minutes illuminations. 我是高中英语老师
