초록

식물 내생 세균인 Bacillus velezensis YC7010은 벼의 병원성 세균과 곰팡이에 대해 전신유도저항성을 일으키며, 식물생육촉진 및 항생작용의 특징을 가지고 있다. 대한민국 진주지역 벼의 근권에서 분리된 B. velezensis YC7010의 유전체는 3,790개의 단백질-암호화 유전자(86 tRNAs와 27 rRNA 유전자)로 구성되어 있으며, 3,975,683 염기쌍의 환상 염색체이다. 유전체 분석을 통해 식물의 발달과 생육을 촉진하는 휘발성 화합물, 식물호르몬 생산, surfactin, plipapastatin, bacillibactin, bacillaene 같은 활성 화합물의 생합성, 식물 내부정착 및 군집화와 관련된 유전자들이 유전체에 존재하는 것을 확인하였다

Bacillus velezensis YC7010 is an endophytic bacterium isolated from the rice rhizosphere in Jinju, Republic of Korea, with properties conductive to growth promotion, antibiosis and induced systemic resistance to significant, soil-borne rice fungal and bacterial pathogens. The genome of B. velezensis YC7010 comprises a 3,975,683 bp circular chromosome which consists of 3,790 protein-coding genes (86tRNA and 27rRNA genes). Based on genomic analysis, we identified genes involved in colonization and establishment inside the plant, biosynthesis of antibiotic compounds such as surfactin, plipapastatin, bacillibactin, and bacillaene, as well as the production of the phytohormones and volatile compounds which serve to promote the plants growth and development.
