Plant Growth-Promoting Rhizobacteria – Biotechnological Tools to Improve Cereal Yields

Abstract

Ensuring food security for the world’s growing population is a significant challenge for scientists. Efforts are constantly being made to solve this problem, including the use of expensive molecular engineering techniques, which are not always successful. A cost-effective and environmentally friendly biotechnological alternative would be the use of plant growthpromoting rhizobacteria, demonstrated by numerous studies to play many beneficial roles in improving plant traits, e.g. enhanced yields.
