“…In contrast to other studies in tobacco (15), Arabidopsis (16), and the monocots oat and rye (19), no V-type ATPase was identified in the poplar DRMs. Interestingly, the relative abundance of P-type H ϩ -ATPases was increased in Arabidopsis DRMs during cold acclimation, accompanied with a decrease in V-type H ϩ -ATPase subunits (55), consistent with the observation that the expression of H ϩ -ATPase genes changes as a result of abiotic and biotic stresses (56). Similarly, the expression of plant Ca 2ϩ -ATPases has been associated with salt stress (57) and the maintenance of calcium homeostasis within the cell (58).…”

“…The gene annotation results indicated that markers found to be significantly associated with both PEG_RI and Heat_RI corresponded to putative proteins with enzyme activity such as ATPase (IWA5785). ATPase plays a crucial role in transporting solutes in and out of the cell through the cell membrane [74]. Other SNP sequences were found to correspond to beta-transducing proteins (IWA3131, IWA3133, IWA6825, and IWA6826), which play an important molecular role in translocating molecules through the plant cell membrane and tolerance to abiotic stress [75].…”

Cell Membrane Stability and Association Mapping for Drought and Heat Tolerance in a Worldwide Wheat Collection

Worldwide periods of heat and drought are projected to be more frequent, longer, and occurring earlier, which could deleteriously affect the productivity of cool-season crops including wheat (Triticum spp.). The coexistence of heat and drought stresses affects plant biochemical and physiological processes including cell membrane function. The increased permeability and leakage of ions out of the cell has been used as a measure of cell membrane stability (CMS) and as a screen test for stress tolerance. The main objectives of this research were to: (1) screen a global spring wheat panel for CMS by exposing leaf tissue to heat treatment and osmotic pressure (PEG 600), (2) identify potential quantitative trait loci (QTL)/genes linked with CMS using genome-wide association mapping, and (3) estimate the relationship between the field performance and measured CMS. The results indicated highly significant differences among the 2111 spring wheat accessions regarding CMS. Moreover, several SNPs were found to be significantly linked with CMS. The annotation of the significant SNPs indicated that most of these SNPs are linked with important functional genes, which control solute transport through the cell membrane and other plant biochemical activities related to abiotic stress tolerance. Overall, this study demonstrated the use of genome-wide association mapping for the identification of potentially new genomic regions associated with CMS. Tolerant genotypes identified in this study proved to be more productive under preliminary field stress conditions. Thus, the identified membrane-stable accessions could be used as parental genotypes in breeding programs for heat or drought stress tolerance.

“…Plant membrane H + -ATPases are often evaluated as factors taking part in plant responses to stress conditions [7,29], and the cross-adaptation to different temperature stresses among them [3,4]. A burst of free salicylic acid-induced thermotolerance at a temperature of 38±0.5ºC appeared subsequent to a change in both the activity and amount of PM H + -ATPase in pea leaves [5].…”

“…One of the key molecular players in cell homeostasis is plasmalemma H + -ATPase, which establishes a proton-electrochemical gradient across the plasma membrane, as well as the tonoplast H + -ATPase and H + -PPase, which are involved in such intricate physiological processes as intracellular pH regulation, cell elongation, and adaptation to different temperature stresses [3][4][5][6][7][8]. In our earlier work dealing with H + -ATPase activity and proton transport peculiarities in freezing-tolerant and non-tolerant genotypes of meadow fescue (Festuca pratensis Huds.…”

The aim of this work was to examine H+-ATPase hydrolytic activity and the stability of transmembrane electrochemical gradients in membrane vesicles isolated from seedlings and leaf cells of an invasive Washington lupine (Lupinus polyphyllus Lindl.) and compare them with non-invasive yellow lupine (Lupinus luteus L.). Temperatures of 25 and 30°C, keeping in mind possible climate warming, were used. For harder stress conditions, short term cold treatment (−8°C in vivo) was used. Plasmalemma-, tonoplast-, and endoplasmic reticulum-enriched membrane fractions were obtained from a sucrose density gradient and identified. Differences in ATPase hydrolytic activity were significant only between lupine species and were more obvious in plasmalemma-enriched fractions. Preincubation of seedlings and leaves at −8°C for 15 min to 24 h showed that microsomic fraction membranes of invasive lupine were more stable (according to Na+-diffusive potential) at low temperature compared to yellow lupine ones. The level of transmembrane electrochemical potential, mainly evoked by ATP-dependent active proton transport, was almost equal in both lupine species. Supposedly, the cells of invasive lupine are able to maintain transmembrane electrochemical potential by the employment of lower hydrolytic activity of H+-ATPase, thus saving energy for growth.
