Inoculation of ACC deaminase-producing endophytic bacteria down-regulates ethylene-induced pathogenesis-related signaling in red pepper (Capsicum annuum L.) under salt stress.

Pathogenesis-related (PR) signaling plays multiple roles in plant development under abiotic and biotic stress conditions and is regulated by a plethora of plant physiological as well as external factors. Here, our study was conducted to evaluate the role of an ACC deaminase-producing endophytic bacteria in regulating ethylene-induced PR signaling in red pepper plants under salt stress. We also evaluated the efficiency of the bacteria in down-regulating the PR signaling for efficient colonization and persistence in the plant endosphere.

Genome-based Reclassification of Paraburkholderia insulsa as a Later Heterotypic Synonym of Paraburkholderia fungorum and Proposal of Paraburkholderia terrae subsp. terrae subsp. nov. and Paraburkholderia terrae subsp. steynii subsp. nov.

Based on the 16S rRNA gene sequences similarity of > 99.8%, the phylogeny of 88 Paraburkholderia strains was reconstructed. Further, they were subjected to overall genome-related indices (OGRI), which resulted in the identification of distinct pairs of species that were closely related.

sp. nov., a moderately halophilic bacterium isolated from beach soil in India.

A moderately halophilic, Gram-stain-negative, aerobic bacterium, strain D1-1, belonging to the genus , was isolated from soil sampled at Pentha beach, Odisha, India. Phylogenetic trees reconstructed based on 16S rRNA genes and multilocus sequence analysis of and genes revealed that strain D1-1 belonged to the genus and was most closely related to YKJ-16 (98.1 %) followed by Al12 (97.
