Identification of sigma factor 54-regulated small non-coding RNAs by employing genome-wide and transcriptome-based methods in rhizobium strains.

Unlabelled: -legume symbiosis is considered as the major contributor of biological nitrogen fixation. Bacterial small non-coding RNAs are crucial regulators in several cellular adaptation processes that occur due to the changes in metabolism, physiology, or the external environment. Identifying and analysing the conditional specific/sigma factor-54 regulated sRNAs provides a better understanding of sRNA regulation/mechanism in symbiotic association.

Prediction and identification of novel sRNAs involved in Agrobacterium strains by integrated genome-wide and transcriptome-based methods.

Small RNAs (sRNAs) are a class of gene regulators in bacteria, playing a central role in their response to environmental changes. Bioinformatic prediction facilitates the identification of sRNAs expressed under different conditions. We propose a novel method of prediction of sRNAs from the genome of Agrobacterium based on a positional weight matrix of conditional sigma factors.
