“…ETH treatment significantly decreased the content of MDA, while STS treatment elevated MDA level in NaCl-stressed alfalfa. After NaCl stress, the content of H 2 O 2 increases in salt-sensitive varieties Juneng 418Q and Sibeide, which was same with the result for alfalfa cultivar Magnum Salt (Lou et al, 2018). H 2 O 2 content decreases after ETH or ACC treatment, which alleviates the degree of oxidative damage of cell membrane system and improves the salt tolerance of alfalfa to a certain extent.…”

Alfalfa (Medicago sativa L.) is an important forage, and salinity is a major stress factor on its yield. In this study, we show that osmotic stress retards alfalfa seedling growth, while ionic/oxidative stress reduces its seed germination. Ethylene treatment can recover the germination rate of alfalfa seeds under salt stress, while ethylene inhibitor silver thiosulfate exacerbates salt effects. ETH reduces the accumulation of MDA and H 2 O 2 and increases POD activity. ETH and ACC improve the salt tolerance of alfalfa by increasing proline content under salt stress. In contrast, STS inhibits alfalfa seed germination by reducing POD activity. NaCl treatment reduces chlorophyll content in alfalfa leaves, while ETH and ACC can increase the chlorophyll content and promote seedling growth. ETH promotes the growth of alfalfa in saline condition by reducing the expression of MsACO and MsERF8 genes, while increases its germination rate by upregulating MsERF11 gene. Silencing of MsETR2, a putative ethylene receptor gene in alfalfa, abolishes ethylene triggered tolerance to salt stress. In summary, we show that ethylene improves salt tolerance in alfalfa via MsETR2 dependent manner, and we also analyze the regulatory mechanism of ethylene during germination of alfalfa seeds under salt stress.

“…Radhakrishnan et al [ 150 ] reported that the addition of spermidine significantly ameliorated the devastating effects of osmotic stress by regulating the level of plant hormones and antioxidants. In a most recent study in alfalfa, the exogenous application of sperimidine positively alleviates SS-induced damage [ 151 ]. Nahar et al [ 152 ] reported that exogenous application of polyamines maintained nutrient homeostasis and reduced cellular Na content as well as regulated endogeneous polyamine concentrations in mungbean under salinity stress.…”

Salinity is an ever-present major constraint and a major threat to legume crops, particularly in areas with irrigated agriculture. Legumes demonstrate high sensitivity, especially during vegetative and reproductive phases. This review gives an overview of legumes sensitivity to salt stress (SS) and mechanisms to cope with salinity stress under unfavorable conditions. It also focuses on the promising management approaches, i.e., agronomic practices, breeding approaches, and genome editing techniques to improve performance of legumes under SS. Now, the onus is on researchers to comprehend the plants physiological and molecular mechanisms, in addition to various responses as part of their stress tolerance strategy. Due to their ability to fix biological nitrogen, high protein contents, dietary fiber, and essential mineral contents, legumes have become a fascinating group of plants. There is an immense need to develop SS tolerant legume varieties to meet growing demand of protein worldwide. This review covering crucial areas ranging from effects, mechanisms, and management strategies, may elucidate further the ways to develop SS-tolerant varieties and to produce legume crops in unfavorable environments.

“…The pigment concentration was calculated based on the method of Porra et al 19 Briey, the absorbance of the extracted supernatant was measured spectrophotometrically at 652 nm (A 652 ) and 665 nm (A 665 ). Intracellular chlorophyll a and b concentrations were calculated using the following eqn (4) Chlorophyll uorescence parameters of the microalgal cells were tested by pulse modulation uorometer (FMS-2, Hansatech, Britain). The dark adaptation time in this experiment was 10 minutes.…”
