Pantoea ananatis B1-9 is an endophytic Gram-negative rhizobacterium that was isolated for its ability to promote plant growth and improve crop yield in the field. Here we report the draft genome sequence of P. ananatis B1-9.

Article Synopsis
- - A study screened 7,638 bacteria from the rhizosphere of various plant species in Korea, specifically looking for plant growth-promoting rhizobacteria (PGPR) that help cucumber seedlings grow.
- - After analysis, 90 strains were identified as PGPR, with 68 being Gram-positive and 22 Gram-negative, categorized into 21 genera and 47 species, primarily featuring Bacillus, Paenibacillus, and Pseudomonas.
- - This research represents the largest effort to date in isolating diverse PGPR, which could enhance our understanding of plant-microbe interactions and potentially improve crop production practices.
Article Synopsis
- Paenibacillus polymyxa E681 is a beneficial bacterium found in the soil around winter barley in South Korea, known for promoting plant growth and fighting plant diseases.
- The complete genome of this bacterium is 5.4 million base pairs long, highlighting its unique adaptations for living in close association with plants.
- Key features of its genome include the ability to produce plant growth hormones, antibiotics, and enzymes that help break down organic material.
Article Synopsis
- In 2007-2008, Sclerotium rolfsii caused a fruit rot in melons grown in a vinyl house in Jinju City, Korea.
- Initial symptoms included watersoaking lesions that eventually led to rotting and the appearance of white mycelial mats on the fruit's surface, along with the formation of globoid sclerotia.
- This study identified S. rolfsii as the cause of the fruit rot through observing its mycological characteristics and pathogenic effects on the melon plant, marking the first recorded instance of this issue in Korea.
Pseudomonas fluorescens B16 is a plant growth-promoting rhizobacterium. To determine the factors involved in plant growth promotion by this organism, we mutagenized wild-type strain B16 using OmegaKm elements and isolated one mutant, K818, which is defective in plant growth promotion, in a rockwool culture system. A cosmid clone, pOK40, which complements the mutant K818, was isolated from a genomic library of the parent strain.
