Co-application of organic amendments and Cd-tolerant rhizobacteria for suppression of cadmium uptake and regulation of antioxidants in tomato.

Cadmium (Cd) contamination is a major environmental concern with well-reported adverse impacts on environment and living entities. It limits the productivity of agricultural crops due to its excessive entry to plant tissues, and subsequent toxic effects on their growth and physiology. Application of metal tolerant rhizobacteria in combination with organic amendments has shown beneficial impacts in sustaining plant growth, on account of amendments mediated decreased metal mobility via different functional groups, as well as provision of carbon to microorganisms.

Endophytic bacteria perform better than endophytic fungi in improving plant growth under drought stress: A meta-comparison spanning 12 years (2010-2021).

Drought stress is a serious issue that affects agricultural productivity all around the world. Several researchers have reported using plant growth-promoting endophytic bacteria to enhance the drought resistance of crops. However, how endophytic bacteria and endophytic fungi are effectively stimulating plant growth under drought stress is still largely unknown.
