Abstract

Chryseobacterium sp. strain T16E-39, isolated from roots of a tomato plant, promotes plant growth and suppresses phytophthora blight and bacterial wilt diseases. The complete genome of strain T16E-39 consists of a circular chromosome with 4,872,888 base pairs with a G + C content of 35.22%. The genome includes 4,289 coding sequences, 15 rRNAs, and 71 tRNAs. We detected genes involved in phosphate solubilization, phytohormone regulation, antioxidant activity, chitin degradation, and the type IX secretion system (T9SS) that may be related to growth promotion and disease suppression in plants.

토마토 뿌리에서 분리한 Chryseobacterium sp. T16E-39 균주는 식물생육촉진과 역병, 시들음병에 대한 억제효과가 있었다. 이 균주의 유전체 염기서열은 4,873,888 염기쌍이었으며 G + C 함량은 35.22%이었다. 이 유전체는 4,289개 단백질 유전자, 15개 rRNA 유전자, 71개 tRNA 유전자를 포함하였다. T16E-39 균주의 유전체에서 인산가용화, 식물호르몬 조절, 항산화 활성, 키틴 분해, 제9형 분비시스템에 관여하는 유전자를 확인하였으며, 이들 유전자는 식물의 생육을 촉진하고 병발생을 억제하는 기작과 관련되어 있을 것으로 판단된다.
