Description

Past studies of structural changes of chloroplast protein spectrum changes membrane, chlorophyll content and chlorophyll ratio a / c, water content and dry matter, and for the functional activity of pea plants heated at 450С and light KLK 16 for 5, 10, 20, 40 and 80 min. It is shown that in the first 5 minutes of warm-up begins rebuilding the Grand ultrastructure, degradation of LHC II proteins by significant loss of functional activity, changes in the ratio of chlorophyll a / v and loss of moisture. Over the next 10-20 minutes ultrastructure stabilized in a new form, slightly increased protein content LHC II, reduced functional activity. Further changes related to accumulation of starch in chloroplasts and a decrease in protein content in the membranes. The data obtained provide new knowledge of the theory of plant adaptation to adverse environmental conditions.
