WebSep 19, 2008 · In maize, a typical C 4 species of the NADP-malic enzyme subtype, MS chloroplasts are granal at all stages of development, whereas BS counterparts are fully agranal (7, 8). Although the pathways for carbon assimilation in bundle sheath cells are well established, the exact supramolecular organization of the respective photosynthetic … WebJul 1, 1973 · Abstract. Granum-containing chloroplasts from mesophyll cells of maize (Zea mays L. var. MV 861) leaves exhibited circular dichroism spectra with a large double signal; peaks at 696 nm (+) and 680 nm (−).In the circular dichroism spectra obtained with agranal chloroplasts of bundle sheath cells, this large double signal is absent.
WebCorrect option is C) Chloroplast has a coin-shaped structure which is known as thylakoids which are placed one above the another to form stacks known as grana. Certain … WebThe effect of plastocyanin on photosystem I activity in the grana-containing chloroplasts was similar to that on NADP photoreduction from water.In the presence of plastocyanin, the rates of NADP photoreduction from water were about the same in the agranal and granal chloroplasts, but photosystem I activity was considerably higher in bundle ...
Webserved in the case of both granal and agranal chloroplasts, and it was not affected either by low salt or by digitonin treatment. A positive peak at about 515 nm was higher in granal than in agranal chloroplasts. Typical chloroplast lamellae consist of different regions possessing or lacking the capacity to form grana (10). The WebThis study examines, to our knowledge for the first time, the mobility of photosynthetic pigment-protein complexes in unstacked thylakoid regions in the C 3 plant Arabidopsis (Arabidopsis thaliana) and agranal bundle sheath chloroplasts of the C 4 plants sorghum (Sorghum bicolor) and maize (Zea mays) by the fluorescence recovery after ...
WebWe investigated the organization of photosystem II (PSII) in agranal bundle sheath thylakoids from a C4 plant maize. Using blue native/SDS-PAGE and single particle analysis, we show for the first time that PSII in the bundle sheath (BS) chloroplasts exists in a dimeric form and forms light-harvesting complex II (LHCII)·PSII supercomplexes. We …
