Plant response to drought stress simulated by ABA application: Changes in chemical composition of cuticular waxes

Popis výsledku v původním jazyce

Plant cuticles form the effective barrier between epidermal plant cells and the atmosphere. It is composed of the cutin matrix and embedded soluble lipids (waxes). We tested the effect of drought stress simulation by the exogenous application of abscisicacid (ABA) on cuticular wax amount and composition. ABA-treated plants and control plants differed in total aboveground biomass, leaf area, stomatal density and aperture, and carbon isotope composition. They did not differ in total wax amount per area but in the abundance of particular components. ABA-treated plants contained significantly higher proportions of aliphatic components characterized by chain length larger than C-26. This can lead to a higher hydrophobicity of the cuticular transpiration barrier and thus decrease cuticular water loss in ABA-treated plants. Shift towards wax compounds having a higher average chain length can be interpreted as an adaptive response of plants towards drought stress.
