“…Although the biochemical mechanisms involved in these plant responses are not clearly elucidated, the pivotal role of phytohormones such as salicylic acid (SA), jasmonic acid (JA), and ethylene (ET) has been widely reported in the literature [93][94][95][96]. Arabidopsis thaliana inoculated with the endophytic Streptomyces sp.…”

The genus Streptomyces comprises filamentous Gram-positive bacteria that are widely recognized for their ability to produce bioactive compounds such as antimicrobial, antiparasitic and immune-suppressing compounds via secondary metabolism. These bioactive compounds represent a third of all commercially available antibiotics. Streptomycetes have been found in beneficial associations with plants where they have improved plant growth and protected against pests, which have attracted the attention of researchers worldwide. This review focuses on the potential of streptomycetes as plant growth-promoting bacteria (PGPS) and considers features related to secondary metabolic pathways, interactions with host plants and recent advances in elucidating plant growth-promoting mechanisms. Such advances in basic knowledge have increased the prospects for streptomycetes to be used as bioinoculants for sustainable agriculture.

In the face of global changes, plants must adapt to a wide range and often combined biotic and abiotic stresses that seriously impaired plant growth and development. Plants develop complex strategies to deal with water stress conditions, soil fertility losses, soil pollutions, pests, and disease. Emerging evidence suggest the involvement of common hormonal players in plant defense signaling pathways triggered in response to biotic and abiotic stresses. Besides plant strategies, plant growth-promoting rhizobacteria (PGPR), which colonize the root system and establish cooperative interactions with plants can improve their growth and help them to adapt to and cope with multiple stresses including drought, salinity, heavy metal pollutions, and parasites. Accordingly, PGPR supply added values to the plant defense strategies by expressing many relevant functions for modulating the plant hormonal balance, increasing nutrients supply to the plant, improving the functional and phy sical properties of protective barriers against plant parasites. Among PGPR, Azospirillum strains were long viewed as biofertilizers and less as biocontrol agents. It is becoming evident that Azospirillum is able to protect plants against a myriad of detrimental conditions. This review provides an update of works regarding the ability of Azospirillum strains to alleviate plant stress and brings out the relevant involved plant-benefi cial functions. Developing PGPR-based bio-inoculants is a promising strategy to improve the growth and health of crops and develop sustainable agriculture.

Inoculation experiments with the endophytic bacterium Azospirillum sp. strain B510, an isolate from surface-sterilized stems of field-grown rice, were conducted in pots in a greenhouse, and in paddy fields in Hokkaido, Japan. B510 significantly enhanced the growth of newly generated leaves and shoot biomass under greenhouse conditions. When rice seedlings were treated with 1×10 8 CFU ml −1 , then transplanted to paddy fields, tiller numbers and seed yield significantly increased. Azospirillum sp. strain B510 is a promising bacterial inoculant for plant growth promotion and agricultural practices.
