Beneficial effects of low selenium levels in Lallemantia iberica plants subjected to salinity stress
Selenium (Se) at high concentrations can cause toxic effects in plants, whereas at low concentrations it enhances resistance to certain abiotic stresses. The possible mechanisms of the Se-enhanced tolerance of plants to salinity stress remain elusive. In this work, effect of Se supplementation at 0, 0.1, 1 and 10 mg l-1 sodium selenate was studied in Lallemantia iberica plants subjected to salt...
متن کاملRecovery of the Photosynthetic Apparatus in Bean Plants after High- and Low-temperature Induced Photoinhibition *
The recovery after photoinhibition in 20-day-old bean plants (Phaseolus vulgaris L.) induced by 4 h treatment with low (12°C), normal (24°C) and high (42°C) temperatures under high (1000 μmol.m–2.s–1) and low (100 μmol.m–2.s–1) photon flux density (PFD) was studied. The changes in the photosynthetic apparatus were analysed using chlorophyll fluorescence measurements. The ratios Fv/Fm measured b...
متن کاملLow Temperature Mitigates Cardia Bifida in Zebrafish Embryos
The coordinated migration of bilateral cardiomyocytes and the formation of the cardiac cone are essential for heart tube formation. We investigated gene regulatory mechanisms involved in myocardial migration, and regulation of the timing of cardiac cone formation in zebrafish embryos. Through screening of zebrafish treated with ethylnitrosourea, we isolated a mutant with a hypomorphic allele of...
متن کاملExogenous Melatonin Mitigates Acid Rain Stress to Tomato Plants through Modulation of Leaf Ultrastructure, Photosynthesis and Antioxidant Potential.
Acid rain (AR) is a serious global environmental issue causing physio-morphological changes in plants. Melatonin, as an indoleamine molecule, has been known to mediate many physiological processes in plants under different kinds of environmental stress. However, the role of melatonin in acid rain stress tolerance remains inexpressible. This study investigated the possible role of melatonin on d...
متن کاملExogenous application of glycinebetaine increases chilling tolerance in tomato plants.
Tomato (Lycopersicon esculentum Mill. cv. Moneymaker) plants are chilling sensitive, and do not naturally accumulate glycinebetaine (GB), a metabolite that functions as a stress protectant. We reported previously that exogenous GB application enhanced chilling tolerance in tomato. To understand its protective role better, we have further evaluated various parameters associated with improved tol...
