Protective role of exogenously supplied salicylic acid and PGPB (Stenotrophomonas sp.) on spinach and soybean cultivars grown under salt stress

Bhavna Nigam, Rama Shanker Dubey, Dheeraj Rathore

Summary: Managing sustainable crop production under escalating soil salinity is a major challenge in the coming years. Exogenous application of protectants can ameliorate the adverse effects of salinity on plant growth. This study evaluated the potential role of salicylic acid (SA) and PGPB (Stenotrophomonas sp.) on spinach and soybean cultivars grown under two different salt concentrations. The results showed that 100 ppm salt had more severe effects than 50 ppm salt on the crops and cultivars. Exogenous protectants improved plant growth and yield, as well as osmotic adjustment and antioxidant activity under salt stress. Overall, PGPB was found to be a more effective protectant than SA in reducing salt-induced yield loss.

Mechanistic insights on melatonin-mediated plant growth regulation and hormonal cross-talk process in solanaceous vegetables

Muhammad Ahsan Altaf, Nitin Sharma, Jagmohan Singh, Mahesh Kumar Samota, Parul Sankhyan, Brajesh Singh, Awadhesh Kumar, Safina Naz, Milan Kumar Lal, Rahul Kumar Tiwari, Ravinder Kumar

Summary: The use of plant growth regulators in horticultural crop production is common for improving produce quality and alleviating stresses. The indolamine compound melatonin (MEL) has emerged as a multifunctional molecule that regulates various aspects of growth and stress tolerance in solanaceous vegetable crops. It acts through reactive species signaling, hormonal cross-talk, and modulation of gene expression.

Methyl jasmonate induces postharvest disease resistance to decay caused by Alternaria alternata in sweet cherry fruit

Liuyi Pan, Xurui Chen, Wei Xu, Shangshu Fan, Tian Wan, Juan Zhang, Yuliang Cai

Summary: The study found that methyl jasmonate (MeJA) had a minimal impact on the mycelial growth of Alternaria alternata in vitro at lower concentrations, but significantly reduced decay and enhanced antioxidant enzyme activities in sweet cherry fruits when applied at an optimal concentration. MeJA treatment also up-regulated the expression of key genes related to jasmonic acid biosynthesis and signal transduction pathways, suggesting a mechanism for inducing sweet cherry's resistance to A. alternata.
