Potential of Finger Millet Indigenous Rhizobacterium sp. MSSRFD41 in Blast Disease Management-Growth Promotion and Compatibility With the Resident Rhizomicrobiome.

Finger millet [ (L). Gaertner] "Ragi" is a nutri-cereal with potential health benefits, and is utilized solely for human consumption in semi-arid regions of Asia and Africa. It is highly vulnerable to blast disease caused by , resulting in 50-100% yield loss.

sp. nov., isolated from the rhizosphere of the mangrove L.

A Gram-stain-negative, motile, rod-shaped bacterium, designated MSSRFH1, was isolated from the rhizosphere of the mangrove, , in Pichavaram, Tamil Nadu, India. Phylogenetic analysis, based on the 16S rRNA gene sequence of MSSRFH1, indicated that it clustered in the genus and was most closely related to JCM18795 (96.7 % similarity).

Diversity and N-acyl-homoserine lactone production by Gammaproteobacteria associated with Avicennia marina rhizosphere of South Indian mangroves.

The diversity of N-acyl-homoserine lactone (AHL)-producing rhizosphere bacterial community associated with Avicennia marina in the mangrove ecosystems of South India was investigated. Approximately 800 rhizobacteria were isolated from A. marina, and they were screened for the production of AHL using two biosensors, Chromobacterium violaceum CV026 and Agrobacterium tumefaciens NTL4 (pZLR4).
