“…is likely to be an effective PGPR due to some members being endophytic nitrogen-fixing bacteria1617181920. Some Klebsiella genomes have now been reported18202122 but most investigations have focused on their pathogenic or N-fixation genes. By contrast, the genes that contribute to the beneficial activity of PGPR and especially salt tolerance and pH adaptability remain to be studied in detail.…”

“…The genomic analysis in this study also includes comparison of the PGP traits to four closely related and representative PGPR strains that have been studied previously, namely K. variicola 34218 (originally misclassified as K. pneumoniae and then clustered with K. variicola by Garza-Ramos et al . )23, K. variicola At-221920 and K. variicola DX12020, K. pneumoniae MGH7857818. The genome analysis will provide a fundamental basis for future studies towards fully understanding the functions of this organism.…”

This research undertook the systematic analysis of the Klebsiella sp. D5A genome and identification of genes that contribute to plant growth-promoting (PGP) traits, especially genes related to salt tolerance and wide pH adaptability. The genome sequence of isolate D5A was obtained using an Illumina HiSeq 2000 sequencing system with average coverages of 174.7× and 200.1× using the paired-end and mate-pair sequencing, respectively. Predicted and annotated gene sequences were analyzed for similarity with the Kyoto Encyclopedia of Genes and Genomes (KEGG) enzyme database followed by assignment of each gene into the KEGG pathway charts. The results show that the Klebsiella sp. D5A genome has a total of 5,540,009 bp with 57.15% G + C content. PGP conferring genes such as indole-3-acetic acid (IAA) biosynthesis, phosphate solubilization, siderophore production, acetoin and 2,3-butanediol synthesis, and N2 fixation were determined. Moreover, genes putatively responsible for resistance to high salinity including glycine-betaine synthesis, trehalose synthesis and a number of osmoregulation receptors and transport systems were also observed in the D5A genome together with numerous genes that contribute to pH homeostasis. These genes reveal the genetic adaptation of D5A to versatile environmental conditions and the effectiveness of the isolate to serve as a plant growth stimulator.

“…However, in other cases, K. variicola infections are highly lethal (7). Plant, insect and clinical K. variicola strains are capable of fixing nitrogen and promoting plant growth (8); they seemingly have different epidemiological dynamics in comparison to K. pneumoniae (9). A genomic analysis would reveal K. variicola virulence or antibiotic resistance genes and genes involved in its association with plants.…”

Three endophytic Klebsiella variicola isolates—T29A, 3, and 6A2, obtained from sugar cane stem, maize shoots, and banana leaves, respectively—were used for whole-genome sequencing. Here, we report the draft genome sequences of circular chromosomes and plasmids. The genomes contain plant colonization and cellulases genes. This study will help toward understanding the genomic basis of K. variicola interaction with plant hosts.

“…12 Likewise, K. variicola DX120E was identified both by 16S rRNA as rpoB genes, however, a better resolution was obtained with rpoB gene analysis. 13 In addition, K. variicola described in animals and plants was also included in the rpoB phylogenetic analysis.…”
