Pseudomonas spp. can help plants face climate change

Area of Science:

• Agricultural Science
• Microbiology
• Environmental Science

Background:

• Climate change causes agricultural stresses including drought, soil salinity, heatwaves, and flooding.
• These environmental challenges significantly reduce crop yields, threatening food security in vulnerable regions.
• Plant-beneficial bacteria, especially those in the genus Pseudomonas, are known to enhance plant stress tolerance.

Purpose of the Study:

• To review the impacts of climate change-induced stresses on agricultural crops.
• To detail the mechanisms by which plant-beneficial Pseudomonas bacteria alleviate these stresses.
• To provide recommendations for future research on microbial solutions for climate-resilient agriculture.

Main Methods:

• Literature review of studies on climate change impacts on crops.
• Analysis of research on Pseudomonas-plant interactions and stress mitigation.
• Synthesis of information on bacterial mechanisms for enhancing plant stress tolerance.

Main Results:

• Climate change poses significant threats to crop production globally.
• Pseudomonas bacteria employ diverse strategies to improve plant resilience to abiotic stresses.
• Key mechanisms include phytohormone modulation, volatile organic compound production, and root barrier reinforcement.

Conclusions:

• Pseudomonas bacteria represent a promising biological approach to manage climate change impacts on agriculture.
• Further research is needed to fully exploit the potential of these microbes for sustainable crop production.
• Targeted research can accelerate the development of microbial inoculants for climate-smart farming.
