Summary: Drought poses serious threats to global crop production, including oilseed crops like Brassica napus L. Various approaches have been used to increase drought tolerance, but there is room for further improvement. Future research should focus on developing genetically engineered rapeseed plants with enhanced drought tolerance.

Summary: This study investigated the role of multi-traits Serratia fonticola (S1T1) in promoting the growth of Cucumis sativus L. under salinity stress (200 mM). The results showed that plants treated with S. fonticola (S1T1) in the root zone had significantly higher fresh and dry biomass, as well as improved chlorophyll content, compared to the control plants. Additionally, the inoculated plants exhibited increased water potential, decreased abscisic acid levels, and lower electrolytic leakage, indicating the beneficial effects of S. fonticola (S1T1) on cucumber plants under salt stress conditions. Antioxidant analysis revealed a decrease in MDA and H2O2 content, as well as an increase in catalase and superoxide dismutase activity. The symbiotic association of S. fonticola (S1T1) was also found to up-regulate the transcript accumulation of ion transporter genes, contributing to salt-stress tolerance in cucumber plants. In conclusion, the use of S. fonticola (S1T1) as a biofertilizer or microbial plant biostimulant could help alleviate the negative effects of salinity stress and improve cucumber plant growth.

Summary: This study conducted a meta-analysis of 57 studies on the effect of plant growth-promoting rhizobacteria (PGPR) inoculation on plants under drought conditions. The results showed that PGPR inoculation helps plants recover from drought stress and improves drought resistance, particularly for C4 plants. Furthermore, PGPR is more effective in increasing plant biomass, enhancing photosynthesis, and inhibiting oxidant damage under drought conditions. Different taxa and functional traits of PGPR also have varying degrees of effect on plant drought resistance.

Summary: Drought is a major constraint to rain-fed agricultural production, and understanding the mechanisms of ABA-mediated drought responses in plants is critical for ensuring crop yield and global food security. This review highlights the regulation of ABA perception, transcriptional levels of ABA- and drought-related genes, and metabolic pathways to alter drought stress responses in plants.

Summary: Phytoremediation is a cost-effective and sustainable technology that uses plant species to clean up pollutants from soils and waters. Plants can naturally absorb metals and degrade organic molecules, but in some cases, contaminants can hinder plant growth. However, certain root exudates produced by plants can attract bacteria that support plant growth under specific environmental stress, such as the presence of toxic contaminants. These plant growth-promoting rhizobacteria (PGPR) can alleviate metal phytotoxicity and enhance plant biodegradation activity. Additionally, in agriculture, PGPR can help counter abiotic stress and replace harmful inorganic fertilizers.

Summary: This study evaluated the effects of two endophytic bacteria on pearl millet under drought stress conditions. The results showed that the inoculation of pearl millet seeds with endophytes improved plant growth, physiological attributes, phytohormone content, and the expression of drought stress-responsive genes. The endophytic bacteria enhanced the tolerance of pearl millet to drought stress by modulating root growth, plant hormones, physiology, and gene expression.

Summary: Water is a crucial component for the existence of life on Earth. However, extreme climate changes have led to water scarcity in many regions, posing significant challenges. This review aims to analyze and understand the physiological and biochemical responses of plants to drought stress and their ability to mitigate its damaging effects. It also explores the role of plant hormones in drought stress responses and signaling. The information for this review was gathered from various sources, including global search engines and scientific literature databases.

Summary: Plant growth-promoting rhizobacteria (PGPR) are an eco-friendly alternative to chemical use in agriculture, but their efficacy as bioinoculants can be compromised by low colonization capacity in the rhizosphere. To improve colonization, highly competitive strains should be prioritized in field trials. PGPR utilize various mechanisms such as recognizing chemical signals and producing antioxidants to successfully colonize the rhizosphere, as well as producing antimicrobial compounds to inhibit phytopathogenic microorganisms.
