Abstract

Glutamicibacter halophytocola DR408 isolated from the rhizospheric soil of soybean plant at Jecheon showed drought tolerance and plant growth promotion capacity. The complete genome of strain DR408 comprises 3,770,186 bp, 60.2% GC-content, which include 3,352 protein-coding genes, 64 tRNAs, 19 rRNA, and 3 ncRNA. The genome analysis revealed gene clusters encoding osmolyte synthesis and plant growth promotion enzymes, which are known to contribute to improve drought tolerance of the plant.

제천에서의 콩 근권 시료로부터 분리한 Glutamicibacter halophytocola DR408 균주는 내건성 식물생장촉진력을 보이고 있다. 본 연구에서 DR408 균주의 완전한 유전체 서열을 해독한 결과, 유전체의 크기는 3.77 Mbp였으며, G + C 함량이 60.2%였다. 또한 총 3,352개의 유전자 서열과 65개의 tRNA, 19개의 rRNA, 3개의 ncRNA가 존재하였다. 유전체 분석을 통해 식물의 내건성을 향상시킬 수 있는 삼투질 합성과 식물생장촉진 효소를 코딩하는 유전자를 다수 포함하는 것을 확인하였다.
