Novel secondary metabolite from a new species of <i>Hypoxylon saxatilis</i> sp. nov. for suppressing bacterial wilt in tomato.

ABSTRACT: The bacterium Ralstonia solanacearum is an important pathogen that causes wilt disease in tomatoes, leading to a reduction in tomato yield. Therefore, this study aimed to investigate the antibacterial activity of endophytic fungi isolated from medicinal plants against the wilt-causing bacterium R. solanacearum in tomatoes under both laboratory and greenhouse conditions. Forty-eight fungi were isolated from 20 medicinal plant species using the surface sterilization technique. The antagonistic activity against R. solanacearum was subsequently examined using the agar plug diffusion test. Two isolates, Hypoxylon sp. NGPM and Hypoxylon saxatilis KKU-KHP 01, were identified from the midrib of the Acanthus ebracteatus and the petiole of the Gardenia sa
