IMPACT OF WATER DEFICIT ON THE PARAMETERS OF THE WATER EXCHANGE OF LEAVE MESOPHYLL OF MODIFIED ON THE PIP AQUAPORINS GENES ARABIDOPSIS THALIANA (L.) HEYNH. PLANTS
Abstract
The characteristics of water exchange of leaves of Arabidopsis thaliana plants, genetically modified on PIP aquaporins, at different substrate water potential. It is assumed that aquaporins PIP1 subgroup have a significant impact on the rate of stomatal water loss, the contribution of PIP2 aquaporins subgroup in a more significant flow of water into the mesophyll cells.
It is shown that the modified plants are less resistant to water stress than the wild-type plant. Increased expression of PIP aquaporins increases hygromorphic leaf structure, less resistant to water stress were overexpressor pip2; 2-23. Under the conditions of water stress in plants knockout pip2; 1-2 increases resistance to mesophyll tissue dehydration.
