The increase in average annual temperatures from year to year results in pronounced dry seasons. Drought
adversely affects the plants growth and development, causing large economic losses on a global scale.
The effects of drought are manifested both at the plant morphological, as well at the physiological, bio-
chemical and molecular levels. Exposure of plants to drought disrupts the normal water transport through
the cells, which is reflected in the presence and function of water channels - aquaporins, on the mem-
branes. Aquaporins are transmembrane proteins that form channels for the water, and other molecules
flow through cell membranes. They play a very important role in adjusting the water flow through the
cells according to the physiological state. In view of this, in recent years much attention has been paid to
the role of aquaporins in plant responses to drought and other abiotic stress factors, which affect the dis-
ruption of the water regime of plants. Researches are aimed at monitoring changes in the expression of
genes for aquaporins, the presence of aquaporins on membranes and the influence on the absorption,
transport and release of water into the atmosphere. This paper presents analyzes of the structure and reg-
ulation of aquaporin gene expression, as well as scientific research over the past ten years on changes in
aquaporin gene expression in plants exposed to drought. Special emphasis was placed on the results of
bioinformatic analyzes of aquaporins in the horticultural species Impatiens walleriana, and their expression
during drought and rehydration.
