Halotolerant plant growth-promoting bacteria (HT-PGPB) have attracted considerable attention for their significant potential in mitigating salt stress in crops. However, the current exploration and development of HT-PGPB remain insufficient to meet the increasing demands of agriculture. In this study, an HT-PGPB isolated from coastal saline-alkali soil in the Yellow River Delta was identified as J2-5-19.

Introduction: Sorghum bicolor: widely cultivated in Asia and Africa, faces increasing challenges from climate change, specifically from abiotic stresses like drought and salinity. This study evaluates how different sorghum genotypes respond to separate and combined stresses of drought and salinity.
Methods: Carried out with three replications using a randomized complete block design, the experiment measured biochemical and physiological parameters, including stomatal conductance, chlorophyll content, and antioxidant enzyme activities.

Biostimulants are an emerging and innovative class of products that may mitigate the adverse effects of extreme heat, but research on their efficacy in fruit crops is limited. This study addressed this knowledge gap by evaluating the performance of three biostimulants, FRUIT ARMOR™, Optysil®, and KelpXpress™ [active ingredients glycine betaine, silicon, and kelp (Ascophyllum nodosum) extract, respectively] applied to three raspberry genotypes exposed to high temperatures (T ≥ 35 °C/day) inside a glasshouse. 'Meeker' consistently maintained high chlorophyll fluorescence (F/F) and photosynthesis under control and biostimulant treatments.

Ensuring food security is one of the main challenges related to a growing global population under climate change conditions. The increasing soil salinity levels, drought, heatwaves, and late chilling severely threaten crops and often co-occur in field conditions. This work aims to provide deeper insight into the impact of single vs.

Microbe-Assisted Phytoremediation (MAP) is an eco-friendly method for remediating soil contaminated with heavy metals such as cadmium (Cd) and chromium (Cr). This study demonstrates the potential of a king grass-Serratia marcescens strain S27 (KS) co-symbiotic system to enhance heavy metal remediation. The KS symbiosis increased the biomass of king grass by 48 % and enhanced the accumulation of Cd and Cr in the whole plant by 2.
