Plant Growth-Promoting Endophytic Bacteria and Their Potential to Improve Agricultural Crop Yields

Chapter

Abstract

Plant-associated bacteria are known to inhabit rhizosphere (Rhizobacteria), phyllosphere (epiphytes) and endosphere (endophytes). The action of bacterial endophytes residing in plant tissues remained unexplored due to culturing difficulties and lack of advanced identification techniques. Endophytes shield the plant from root pathogen attack by producing biofilm around roots. Rhizobia are perhaps the best example of plant-associated endobacteria as they facilitate N uptake in plants through Rhizobium-legume symbiosis. With certain physiological differences, several species of Rhizobium remain present in legume plants like alfalfa, clover and pea. In this chapter, if not otherwise stated, the ‘endophytes’ are mentioned with reference to endophyte bacteria only.
