A synthesis of functional contributions of rhizobacteria to growth promotion in diverse crops

Abstract

The endophytic microbes are known to live asymptomatically inside their host and play crucial roles in the growth, development, fitness, and diversification of plants. The plant-endophyte association ranges from mutualism to pathogenicity helping the host to combat a diverse array of biotic and abiotic stressful conditions, thus reducing the impact of chemical fertilizers on the environment. The present review is focused on the role of plant growth-promoting bacteria in sustainable production of legume and non-legume crops. Specifically, we described the inoculants used in the production of soybean (Glycine max), alfalfa (Medicago sativa), common bean (Phaseolus vulgaris), subclover (Trifolium subterraneum), different Lotus species, yellow lupin (Lupinus luteus), white carob tree (Prosopis alba), rice (Oryza sativa), maize (Zea mays), wheat (Triticum aestivum), quinoa (Chenopodium quinoa), tomato (Solanum lycopersicum), guinea grass (Megathyrsus maximus) and canola (Brassica napus) in South America.
