Plant growth promotion and biological control of Sclerospora graminicola in pearl millet by endophytic Streptomyces spp
Endophytic Streptomyces spp . were isolated from pearl millet roots and analyzed for growth characteristics on three different media viz., Streptomyces (S) media, casein starch agar and actinomycetes media. Proteolytic activity of Streptomyces was evaluated by using cell free extracts, 23 isolates...

were isolated from pearl millet roots and analyzed for growth characteristics on three different media viz.,
Streptomyces
(S) media, casein starch agar and actinomycetes media. Proteolytic activity of
Streptomyces
was evaluated by using cell free extracts, 23 isolates were found positive and further tested for their inhibition effects on downy mildew pathogen
.
Cell-free extract and the mycelial mats were used as seed soaking and seed dressing treatments, respectively. Twenty days old susceptible coleoptile seedlings were artificially inoculated with
Sclerospora graminicola
pathogen for three consecutive days. The downy mildew suppressing ability (30%) and the disease protection (63%) were observed in
Streptomyces
spp. Isolates S6-19 and S4-19 offered 63% and 56% disease protection against downy mildew respectively and also promoted the vegetative and reproductive growth of the plant. Thus, endophytic
Streptomyces
spp
.
proved as an effective possible biocontrol agent in enhancing the disease resistance. |
