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 کاملEvaluating physiological responses of plants to salinity stress
BACKGROUND Because soil salinity is a major abiotic constraint affecting crop yield, much research has been conducted to develop plants with improved salinity tolerance. Salinity stress impacts many aspects of a plant's physiology, making it difficult to study in toto Instead, it is more tractable to dissect the plant's response into traits that are hypothesized to be involved in the overall to...
متن کاملVariations in leaf soluble amino acids and ammonium content in subtropical seagrasses related to salinity stress.
A survey of leaf soluble amino acids was conducted for four subtropical seagrasses grown at several salinities. Proline functioned as an organic osmoticum in Halodule wrightii Aschers., Thallasia testudinum Banks ex Koenig, and Ruppia maritima L., while alanine functioned in an osmoregulatory capacity in Halophila engelmanni Aschers. When light-and salinity-induced variations in leaf NH(4) and ...
متن کاملHeterologous Expression of the Secale cereal Thaumatin-Like Protein in Transgenic Canola Plants Enhances Resistance to Stem Rot Disease
Canola (Brassica napus L.) is an important oilseed crop. A serious problem in cultivation of this crop andyield loss, are due to fungal disease stem rot caused by Sclerotinia sclerotiorum. The pathogenesis-related(PR) proteins have the potential for enhancing resistance against fungal pathogen. Thaumatin-like proteins(TLPs) have been shown to have antifungal activity on variou...
متن کاملSalinity stress enhances production of solasodine in Solanum nigrum L.
Various in vitro grown tissues (non-regenerative callus, regenerative callus and microshoot derived leaves) of Solanum nigrum L. were cultured under salinity stress (0-150 mM NaCl) for enhanced production of solasodine, a steroidal alkaloid and an alternative to diosgenin, which is used as a precursor for the commercial production of steroidal drugs. The role of plant growth regulators and vari...
