Nitric oxide (NO) functions as a signaling molecule in plant adaptation to changing environmental conditions. NO levels were found increase plants response low temperatures (LTs). However, knowledge of the pathways involved enhanced production under cold stress is still limited. For this reason, we aimed determine role different sources generation cucumber roots exposed 10 °C for short (1 d) and long (6 periods. The short-term treatment seedlings with LT markedly increased plasma...
The effect of heavy metals on the modification plasma membrane H(+)-ATPase (EC 3.6.3.14) activity in cucumber roots was studied. In plants stressed for 2 h with 10 microM or 100 Cd, Cu Ni hydrolytic as well transporting membranes root cells decreased. Transcript levels Cucumis sativus treated Cu, were similar to control, indicating that action did not involve gene expression level. Only exposed Cd level mRNA markedly inhibition proton pump caused by and partially diminished presence...
The effect of heavy metals on plasma membrane (PM) H+-ATPase (EC 3.6.3.14) activity in cucumber (Cucumis sativus) roots was studied. aim this work to explain the mechanism modification PM plants subjected metals. Plants were treated with 10 μM Cd or Cu for 6 d. After 3 d exposure metals, some transferred control conditions a further (3/3 plants). found be increased highest measured as proton transport observed 3/3 plants. Estimation transcript levels C. sativus indicated that action Cd, but...
Vacuolar H+ -ATPase (V-ATPase; EC 3.6.3.14) is the main enzyme responsible for generating a proton gradient across tonoplast. Under cadmium (Cd) stress conditions, V-ATPase activity inhibited. In present work, hydrogen sulfide (H2 S) and peroxide O2 ) cross-talk was analyzed in cucumber (Cucumis sativus L.) seedlings exposed to Cd explain role of both signaling molecules control V-ATPase. gene expression as well H2 S content endogenous production were determined roots plants treated with 100...
In the present study we demonstrate that signalling molecules NO, H2O2 and H2S are important for understanding mechanisms of modification plasma membrane H+-ATPase (EC 3.6.3.14) activity in conditions both salt (50mM NaCl) low temperature (10°C, LT) stress. Plants were subjected to stress 1 or 6 days. After 3 days exposure some plants transferred control another days: post-stressed (3+3). We measured endogenous levels stressed plants. To determine physiological significance induced (PM...
Water and nutrient deficiencies in soil are becoming a serious threat to crop production. Therefore, usable water recovery from wastewater, such as urine grey water, should be considered. In this work, we showed the possibility of using after processing an aerobic reactor with activated sludge which nitrification process takes place. The resulting liquid (nitrified NUG) contains three potential factors that can adversely affect plant growth hydroponic system: anionic surfactants, deficits,...
Plasma membrane NADPH oxidases (RBOHs, EC 1.6.3.1) are known as the main ROS generators involved in plant adaptation to stress conditions. In present work, regulation of oxidase was analyzed cucumber (Cucumis sativus L. var. Krak) seedlings exposed salinity. RBOH activity and gene expression, well H2O2 content, were determined roots plants treated with 50 or 100 mM NaCl for 1 h, 6 days. It found that enzyme increased parallel an enhancement level day. The expression some CsRboh genes induced...
Two electrogenic proton pumps, vacuolar H(+) transporting ATPase (V-ATPase, EC 3.6.3.14) and inorganic pyrophosphatase (V-PPase, 3.6.1.1), co-exist in the membrane of plant cells. In this work, all CsVHA CsVHP genes encoding V-ATPase V-PPase, respectively, were identified cucumber genome. Among them, three CsVHA-c for subunit c two CsVHP1 type I V-PPase analyzed detail. Individual isogenes differentially regulated tissues during development as well under changing environmental conditions....
The effect of Cd and Cu on the tonoplast proton pumps, V‐ATPase (EC 3.6.3.14) V‐PPase 3.6.1.1) was investigated in cucumber roots subjected to 10 µ M metals for 3 6 days. Both hydrolytic transporting activities as well increased under copper stress. In contrast, all examined were inhibited after exposure plants cadmium. changed efficiency coupling between transport ATP hydrolysis whereas H + /PP i stoichiometry not modified. Pre‐incubation control vesicles with caused stimulation V‐PPase,...
When plants are exposed to environmental stress, their growth is inhibited. Under such conditions, controlled inhibition of beneficial for plant survival. Jasmonic acid (JA) a well-known phytohormone that limits growth, which has been confirmed in several species. However, its role cucumber seedlings not yet comprehensively investigated. For this reason, we aimed determine the involvement JA regulation proteins crucial including plasma membrane proton pump (PM H+-ATPase), PM nitrate...
