Randomized trial evaluates effects of Streptomyces on oxidative stress and root exudates in maize, suggesting implications for plant health.

The research aims to explore how different Streptomyces strains affect oxidative stress metabolism and root exudate profiles in maize.
Evaluated interactions between maize and four Streptomyces strains.
Assessed antioxidant enzyme activities and root exudate profiles.
Measured changes in metabolite levels and enzyme activities over 15 days.
Ascorbate peroxidase activity decreased by up to 99%, catalase activity decreased by approximately 70%.
Total amino acids increased 2.3-fold in CLV104-treated plants, while total sugars and phenolic compounds decreased by up to 60% and 70%.
Caffeic acid exudation was reduced by approximately 92% in CLV104-treated plants at 15 days.
