RESUMO
Plant growth-promoting rhizobacteria (PGPR) improve plant productivity and stress resistance. The mechanisms involved in plant-microbe interactions include the modulation of plant hormone status. The Novosphingobium sp. strain P6W was previously described as the bacterium capable of abscisic acid (ABA) degradation, and its inoculation decreased ABA concentrations in planta. The metabolic pathway for the ABA degradation in bacteria is still unknown. Here we present transcriptome data of Novosphingobium sp. P6W grown in the medium supplemented with ABA or fructose as the carbon source. Cleaned FASTQ files for the RNA-seq libraries are deposited in the NCBI Sequence Read Archive (SRA, Identifier: SRP189498) and have been assigned BioProject accession PRJNA529223.
RESUMO
Mechanisms of microbial catabolism of phytohormone abscisic acid (ABA) are still unknown. Here, we report the complete genome sequence of ABA-utilizing Rhodococcus sp. strain P1Y, isolated from the rice (Oryza sativa L.) rhizosphere. The sequence was obtained using an approach combining Oxford Nanopore Technologies MinION and Illumina MiSeq sequence data.
RESUMO
The phytohormone abscisic acid (ABA) plays multiple roles in plant survival and fitness. Significant quantities of ABA are constantly introduced into soil via root exudation, root turnover and incorporation of abscised shoot tissues. In addition, some phytopathogenic fungi synthesize ABA in the course of plant-microbe interactions. The accumulation of soil ABA can inhibit seed germination and root growth but despite this observation, the biochemical pathways of ABA conversion by microorganisms and genetic determinants of the process remain unknown. Here we report on the complete genome sequence of strain P6W, an ABA-utilizing isolate of the genus Novosphingobium. Strain P6W was isolated from the rhizosphere of rice (Oryza sativa L.) seedlings using a selective ABA-supplemented medium. The genome of strain P6W consists of 6,606,532 bp, which includes two chromosomes and two plasmids. It comprises of 5663 protein-coding genes and 80 RNA genes. ANI values calculated based on the analysis of nine previously sequenced genomes of members of the genus Novosphingobium ranged from 77 to 92%, which suggests that strain P6W is potentially a new species of the genus Novosphingobium. Functional annotation of genes in the genome of strain P6W revealed a number genes that could be potentially responsible for ABA degradation.
