AB  - Two tomato genotypes with constitutively different ABA level, flacca mutant and wild type of Ailsa Craig cv. (WT), were subjected to three repeated drought cycles, with the aim to reveal the role of the abscisic acid (ABA) threshold in developing drought tolerance. Differential responses to drought of two genotypes were obtained: more pronounced stomatal closure, ABA biosynthesis and proline accumulation in WT compared to the mutant were compensated by dry weight accumulation accompanied by transient redox disbalance in flacca. Fourier-transform infrared (FTIR) spectra analysis of isolated cell wall material and morphological parameter measurements on tomato leaves indicated changes in dry weight accumulation and carbon re-allocation to cell wall constituents in flacca, but not in WT. A higher proportion of cellulose, pectin and lignin in isolated cell walls from flacca leaves further increased with repeated drought cycles. Different ABA-dependent stomatal closure between drought cycles implies that acquisition of stomatal sensitivity may be a part of stress memory mechanism developed under given conditions. The regulatory role of ABA in the cell wall restructuring and growth regulation under low leaf potential was discussed with emphasis on the beneficial effects of drought priming in developing differential defense strategies against drought.

AB  - Drought is one of the main consequences of climate change that negatively affects plant growth and development, which in turn leads to a reduction in yield. The objective of this study was to investigate the effects of the physiological responses to the drought stress of maize plants (population IP3722), obtained from seeds of different ages (originating from 2012. and 2016) and different previous experience (the seeds formed in 2012. were more exposed to drought than in 2016.). Two populations responded to drought treatment by a significant decrease of shoot fresh and dry weight, this was followed with decrease leaf area and transpiration rate. Drought treatments enabled induction and differentiation of chemical signals of drought (abscisic acid-ABA and xylem pH) and hydraulic signals (leaf water potential), and monitoring of their activity on stomatal conductance. The data showed that hydraulic signals have the same impact on stomatal reactions in the D2012 and D2016 treatments. They also indicated that the chemical signal of ABA works toward stomatal closure, but that the effect depends on whether it originates from the leaf or the root. Leaf-originating ABA had more effect on the closure of D2012 stomata, while root-originating ABA and pH was more active in the D2016.
AB  - Suša nastaje kao posledica klimatskih promena, koja negativno utiče na rast i razvoj biljaka, a to dovodi do smanjenja prinosa. Cilj ovog rada bio je da se istraži efekat suše na fiziološke reakcije biljaka kukuruza (IP3722), koje su dobijene iz semena različite starosti (regenerisano 2012. i 2016.) i različitih prethodnih iskustava (semena koja su formirana 2012. su bila u većoj meri izložena suši nego ona iz 2016.). Suša je kod oba uzorka dovela do smanjenja sveže i suve mase nadzemnog dela biljke, što je bilo praćeno opadanjem lisne površine i stomatalne provodljivosti. Tretmanom suše su indukovani hemijski signali (ABA i pH) i hidraulički signal (vodni potencijal), koji su uticali na provodljivost stoma. Podaci su pokazali da hidraulički signal ima podjednak udeo na zatvaranje stoma u tretmanu D2012 i D2016. Takođe, ABA kao hemijski signal dovodi do zatvaranja stoma, ali ovaj efekat zavisi od toga da li ABA potiče iz korena ili lista. ABA poreklom iz lista je imala značajniji doprinos u zatvaranju stoma kod D2012, dok ABA poreklom iz korena i pH kod tretmana D2016.
