AI Article Synopsis
- A study investigated drought protection in plants using xeroprotectant-producing microorganisms in tomato and pepper crops.
- The focus was on how these microorganisms promote growth and enhance drought resilience through mechanisms like phytohormone production and antioxidants.
- The research suggests a correlation between trehalose production in certain microorganisms and improved plant drought protection, particularly highlighting the role of the trehalose-synthesizing KT2440 strain.
Article Abstract
A collection of desiccation-tolerant xeroprotectant-producing microorganisms was screened for their ability to protect plants against drought, and their role as plant growth-promoting rhizobacteria was investigated in two different crops (tomato and pepper). The most commonly described biochemical mechanisms for plant protection against drought by microorganisms including the production of phytohormones, antioxidants and xeroprotectants were analyzed. In particular, the degree of plant protection against drought provided by these microorganisms was characterized. After studying the findings and comparing them with results of the closest taxonomic relatives at the species and strain levels, we propose that trehalose produced by these microorganisms is correlated with their ability to protect plants against drought. This proposal is based on the increased protection of plants against drought by the desiccation-sensitive microorganism KT2440, which expresses the AB genes for trehalose biosynthesis .
