AI Article Synopsis
- - A new bacterial strain (JJ-246) was isolated from the roots of corn plants (Zea mays) and is classified as a Gram-positive, aerobic, endospore-forming bacterium.
- - Genetic analysis revealed that JJ-246 is closely related to the species Paenibacillus oenotherae but shows significant differences in genome similarities, indicating it is a distinct species.
- - The genome of JJ-246 contains various genes that may benefit plants, such as those involved in root colonization, stress protection, and nutrient acquisition, leading to the proposal of the new species name Paenibacillus plantiphilus.
Article Abstract
A Gram-strain positive, aerobic, endospore-forming bacterial strain (JJ-246) was isolated from the rhizosphere of Zea mays. The 16S rRNA gene sequence similarity comparisons showed a most closely relationship to Paenibacillus oenotherae DT7-4 (98.4%) and Paenibacillus xanthinolyticus 11N27 (98.0%). The pairwise average nucleotide identity and digital DNA-DNA hybridisation values of the JJ-246 genome assembly against publicly available Paenibacillus type strain genomes were below 82% and 33%, respectively. The draft genome of JJ-246 shared many putative plant-beneficial functions contributing (PBFC) genes, related to plant root colonisation, oxidative stress protection, degradation of aromatic compounds, plant growth-promoting traits, disease resistance, drug and heavy metal resistance, and nutrient acquisition. The quinone system of strain JJ-246, the polar lipid profile and the major fatty acids were congruent with those reported for members of the genus Paenibacillus. JJ-246 was shown to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus plantiphilus sp. nov. is proposed, with JJ-246 (= LMG 32093 = CCM 9089 = CIP 111893) as the type strain.
