In present study, we evaluated the effects of Jasmonic acid (JA) on physio-biochemical attributes, antioxidant enzyme activity and gene expression in soybean (Glycine max L.) plants subjected to nickel (Ni) stress. Ni stress decreases shoot root length chlorophyll content by 37.23%, 38.31% 39.21% respectively over control. However, application JA was found improve growth Ni-stressed seedlings terms length. Plants supplemented with Jasmonate restores fluorescence, which disturbed The study...
Brassinosteroids (BRs) are a group of naturally occurring plant steroid hormones that can induce tolerance to various stresses by regulating ROS production in cells, but the underlying mechanisms this scavenging activity BRs not well understood. This study investigated effects 28-homobrassinolide (28-HBL) seed priming on Brassica juncea seedlings subjected combined stress extreme temperatures (low, 4 °C or high, 44 °C) and salinity (180 mM), either alone supplemented with 28-HBL treatments...
The effects of jasmonic acid (JA) and methyl jasmonate (Me-JA) on photosynthetic efficiency expression some photosystem (PSII) related in different cultivars Brassica oleracea L. (var. italica, capitata, botrytis) were investigated. Plants raised from seeds subjected to a pre-sowing soaking treatment varying concentrations JA Me-JA showed enhanced terms qP chlorophyll fluorescence. Maximum quantum PSII (Fv/Fm) was increased over that the control seedlings. This enhancement more pronounced...
Jasmonates are class of plant growth regulators act as signal molecule that intercede various components in physiological and metabolic regulation, stress responses possibly communication through transduction. Oxidative due to heavy metal exposure stimulates synthesis activity antioxidant metabolites enhances enzyme activities could protect tissues. The aim this study was investigate the exogenous effect JA at seed level which can transduce throughout seedling regulate such superoxide...
Environmental stresses pose a major challenge for plant researchers to fulfill increasing food demand. Researchers are trying generate high-yielding and stress-tolerant or resistant varieties using classical genetics modern gene-editing tools; however, both approaches have limitations. Chemical treatments emerged as an alternative improve yield impart stress resilience. Brassinosteroids (BRs) group of phytohormones that regulate various biological processes, including management. With foliar...
Contamination of agricultural soils with heavy metals (HMs) has posed major threat to the environment as well human health. The aim this study was appraise efficiency key-antioxidant enzymes in enhancing plants' tolerance HMs (heavy metals) like copper (Cu) and Cadmium (Cd), under action methyl jasmonate (Me-JA) Cajanus cajan L. Seeds C. treated Me-JA (0, 1 nM) were discretely subjected noxious concentrations Cu Cd 1, 5 mM) raised for 12 days controlled conditions plant growth chamber...
The concentration of copper in soil is increasing, which may potentially affect the crop yield. Brassinosteroids are well known to enhance tolerance towards abiotic stress, but role castasterone this context poorly understood. present study was designed explore potential Brassica juncea plants. Results indicate that increased production superoxide anion radical and hydrogen peroxide, maximum at 0.75 mM exposure (31.71 68.29% 60 days). This overproduction reactive oxygen species hampered...
