s grumble theactivitiesofPFK-2andFBPase a 2incrudeextractsfrommizeleavesPFK-2 and FBPase-2 activity cycle of lightning leaves F2, 6PI we determined the regulation of maize leaf soil culture in the light / dark (12h/12h) during the turn of PFK-2 and FB-Pase activity change of a 2. Clearly see the light PFK2 passive phenomenon,louis vuitton outlet, according to its activity decreased after light lh 33, according to its activity decreased after light l2h 70; dark PFK-2 after treatment with the vitality of the dark time and gradually increase their activity after dark is 8h 2-fold increase in peak (Fig. 3 A c). However, the vitality of FBPase-2 did not change significantly (Figure 3 A c). PFK2/FBPase-2 ratio with illumination time and decreased with the increase of the dark time (Fig. 3 a B). 20h continuous illumination maize leaves of PFK-2 activity decreased (Figure 4), which seems to indicate that light / dark treatment changes in PFK-2 activity and circadian rhythm independent of maize plants. Chloroplasts and cytoplasm of carbon metabolism is coordinated (C ~ eke and Buchananl986). Coordination between the chloroplast and the cytoplasm alone carbohydrate content of the most important factor. Stitt,moncler online, etc. (1984b) report in the light / dark conditions, the cytoplasm of a variety of leaf PFK 2 activity and the effect of a change is tPi concentration is higher than the concentration of dark light; and the three concentrations of carbon compounds is the opposite. Photosynthetic COz fixed carbon products of the first three being through chloroplast membrane and Pi inorganic phosphate exchange translocators. In terms of the cytoplasm. PGA is not only energy and carbon frame, and along with Pi as a regulator messenger. Known to activate PFK-2 Pi. Simultaneous inhibition of FBPase-2; PGA inhibited the PFK2 activity. Thus the dark state Pi concentration in the cytoplasm of maize leaves PFK2 field 3 and F Ⅲ 2 activity and diurnal variation of F. 3ChangesofPFK a 2and ~ FBPase-2activitiesinmaizeleavesdozingdayandnight4 Light / Dark on a 6-fructose corn leaves a fructose kinase-2 and a 2, B_ diphosphate alcohol fermentation activity of high and low concentrations of beneficial PGA PFK-2 activity increased. But our results show that the light Dunhua PFK 2 is not an entirely through the direct impact due to the small molecule compounds, so the increase in the amount of enzyme or enzyme conformational change of state is also related to light passive phenomenon worthy of further exploration. 20h continuous light corn fields ● PFK-2 activity in leaves change process F. ● a1a din ofPFK a 2activityinmaizeleavesduxing20hcontinuingillumination light / dark during the F2, 6P and trends in the concentration of PFK-2 activity of a 2/FBPase ratio is consistent with the trend (Figure 3),mbt shoes sale, that leaves the dark state of F2, 6P content to light. Wirtz et al (1982) that illuminated the F2, 6Pz drop in the concentration of a metabolite of PFK 2 and FBPase-2 regulation of the results. Light when photosynthesis increased PGA concentration in the cytoplasm, the inhibition of PFK-2 increased, causing F2, 6Pz concentration,uggs nederland, thus facilitating the synthesis of sucrose; the other hand with the weakening of photosynthesis. The cytoplasm of three reduction in the level of carbon compounds, prompting F2, 6P concentration. Conducive to sugar degradation. Therefore leaves F2, 6P in the regulation of carbon metabolism plays an important role 相关的主题文章： mbt shoes clearance Octoploid Xiaobingmai its pare uggs 45 lactic acid bacteria beverage analysis of mbt shoes sale Cloning and Characterization of a N |
