Description Streptomyces is a Gram-positive bacterium, with a high guanine þ cytosine (G þ C) content,
belonging to the family Streptomycetaceae and order Actinomycetales. It is found
commonly in marine and fresh water, rhizosphere soil, compost, and vermicompost. Streptomyces
plays an important role in the plant growth promotion (PGP), plant health promotion
(crop protection), degradation of organic residues, and production of byproducts (secondary
metabolites) of commercial interest in agriculture and medical fields. Streptomyces, in the
rhizosphere and rhizoplane, help crops in enhancing shoot and root growth, grain and stover
yield, biologic nitrogen fixation, solubilization of minerals (such as phosphorus and zinc),
and biocontrol of insect pests and plant pathogens. There is a growing interest in the use
of secondary metabolites produced by Streptomyces such as blasticidin-s, kusagamycin, streptomycin,
oxytetracycline, validamycin, polyoxins, natamycin, actinovate, mycostop, abamectin/
avermectins, emamectin benzoate, polynactins and milbemycin for the control of insect
pests and plant pathogens as these are highly specific, readily degradable, and less toxic to
environment (Aggarwal et al., 2016). The PGP potential of Streptomyces is well documented
in tomato, wheat, rice, bean, chickpea, pigeonpea, and pea. This chapter emphasizes the usefulness
of Streptomyces in PGP, grain and stover yields, soil fertility, and plant health
promotion.
