Discovery of a New Rosamicin Derivative from Endophytic Micromonospora rosaria FoRo54 Using Genome Mining Technology.

ABSTRACT: Endophytic FoRo54 was isolated from the roots of Oryza rufipogon (Dongxiang wild rice) collected in China. Based on morphological characteristics and phylogenetic analysis of the 16S rRNA gene sequence, strain FoRo54 was identified as closely related to Micromonospora rosaria. The complete genome of FoRo54 consists of a linear chromosome of 7,057,852 bp with a GC content of 73.8 mol%. Genome mining using antiSMASH revealed 27 biosynthetic gene clusters (BGCs) potentially involved in secondary metabolite biosynthesis, including those associated with kanamycin, rosamicin, and asukamycin, consistent with the antibacterial activities of the strain. Application of a combined genome mining strategy enabled further exploration of the strain's metabolic potential. One new rosamicin d
