摘      要：The deleterious effects of ultraviolet B(UV-B)radiation on photosynthesis and photosynthetic proteins of tropical and temperate plants have been *** tropical plants(black gram and green gram),the temperate plants(carrot and radish)also successfully grown in the tropical *** were exposed to enhanced UV-B radiation under field *** studies show that under enhanced UV-B radiation photosynthetic activity was increased in black *** green gram and radish the UV-B radiation slightly enhanced the photosynthetic activity,but it inhibited the photosynthetic activity in *** comparative results showed changes in contents of thylakoid 55,47,43,33,29,27-25,23 and 17 kDa polypeptides that were significantly lowered in UV-B treated carrot plant when compared to other *** PSII protein profile results showed a strong correlation between the presence of a membrane polypeptide and photosynthetic *** black gram and green gram the UV-B radiation did not produce any significant difference in the PSII *** in the case of radish the UV-B radiation increased the accumulation of 33-28 kDa protein and affected expression of the 63 kDa *** the case of carrot,severe degradation of 32 kDa and 33 kDa,corresponding to D1 and D2 core proteins of PSII,was *** could be concluded that the ability of plants to tolerate increased levels of UV-B radiation,relative to photosynthetic capacity,depends on acclimation processes of the plant in the growing region.
