초록

본 연구에서 생물 및 비생물학적 스트레스에 내성을 유도하는 식물 생육 촉진 세균인 Variovarx sp. PMC12 균주의 유전체 염기서열을 분석하였다. PMC12 균주의 유전체는 5,873,297 bp와 1,141,940 bp 크기의 원형 염색체 2개로 구성되었다. 총 6,436개 단백질 유전자, rRNA 9개, tRNA 64개, ncRNA 3개와 유사유전자 80개가 확인되었다. 유전체상에서 발견된 1-aminocyclopropane-1-carboxylate (ACC) deaminase, 항산화 활성, 인산 가용화, 프롤린 생합성, 시드로포어 생합성과 관련된 유전자들은 PMC12 균주가 염, 온도, 병원균에 대한 스트레스에 대한 식물의 내성 유도와 관련되어 있을 것으로 판단된다.

Variovorax sp. PMC12 is a rhizobacterium isolated from tomato rhizosphere and enhanced the plant resistance to abiotic and biotic stresses. Here we present the complete genome sequence of strain PMC12. The genome is comprised of two circular chromosomes harboring 5,873,297 bp and 1,141,940 bp, respectively. A total of 6,436 protein-coding genes, 9 rRNAs, 64 tRNAs, 3 ncRNAs, and 80 pseudogenes were identified. We found genes involved in 1-aminocyclopropane-1-carboxylate (ACC) deaminase, antioxidant activity, phosphate solubilization, and biosynthesis of proline and siderophore. Those genes may be related to capability of improving plant resistance to various stresses including salinity, cold temperature, and phytopathogen.
