“…Plants quickly synthesized the hormone SA in response to environmental stress. A rapid increase in endogenous free-SA level was observed in plant thermotolerance (Dat et al 1998;Liu et al 2009b). SAG is a major metabolite conjugated form of SA.…”

“…When tobacco mosaic virus (TMV)-inoculated tobacco leaves, the endogenously synthesized SA is primarily converted to SAG (Lee and Raskin 1998;Enyedi et al 1992;Malamy et al 1992). Liu et al (2009b) reported that SAG may act as a signal molecule as SA does involved pea thermotolerance induced by heat acclimation. Fig.…”

“…Salicylic acid (SA), a phenolic compound ubiquitously distributed in plants (Raskin et al 1990), has been proposed as a defense hormone and involved in triggering plants resistance against environmental stresses such as drought, salinity, heat shock, cadmium toxicity and Al toxicity (Abreu and Munne-Bosch 2008;Kovacik et al 2009;Liu et al 2009b;Belkhadi et al 2010;Yang et al 2003). SA mediated signal transduction pathway also seems to be involved in plant response to Al stress.…”

Background and aims Aluminum (Al)-induced citrate exudation has been identified as an important Alresistance mechanism in soybean. Salicylic acid (SA) is a crucial signal molecule modulating numerous environment stresses in plants. This study was to investigate the role of SA in Al-induced citrate exudation from soybean roots. Methods HPLC was used to test the Al-induced endogenous SA changes, effect of exogenous SA / an inhibitor of SA biosynthesis paclobutrazol (PAC) on Al-induced citrate efflux. The activity / transcriptional expression of mitochondrial aconitase (ACO) and a putative citrate transporter gene Gm-MATE1 were examined by an enzyme method or qRT-PCR. Results Al stress caused increase of endogenous free-SA and conjugated SA (SAG). Exogenous SA enhanced the amount of Al-induced citrate secretion from roots, decreased the Al accumulation in root apices and alleviated the Al-induced inhibition of root elongation. PAC decreased the Al-induced enhancement of endogenous free SA and reduced the amount of citrate exudation. SA and Al together treatment further decreased mitochondrial aconitase (ACO) activity and enhanced the transcriptional expression of Gm-MATE1compared to the sole Al treatment. Conclusions Al-induced SA production may act as an early signal to regulate the metabolism and transportation of citrate in soybean roots.

“…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]. We assessed lupine cell H + -ATPase responses to different temperatures, which were close to optimal for plant growth in middle latitudes and Earth climate conditions.…”

“…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.
