Identification and genome insights into <i>Pyrenochaeta nobilis</i>, a novel endophytic fungus isolated from <i>Astragalus membranaceus</i> with gray mold-control activity.

ABSTRACT:

Introduction

Gray mold, caused by the necrotrophic fungus Botrytis cinerea, is a significant threat to agricultural production, especially under low temperature and high humidity conditions. This disease can cause substantial yield losses in various crops, including tomatoes. To address this issue, the search for novel biocontrol agents has become a priority. In this study, we explored the potential of endophytic fungi isolated from wild medicinal plants in the southern foothills of the Daxing'an Mountains in China as biocontrol resources against B. cinerea.

Methods

Endophytic fungi were isolated from the roots of Astragalus membranaceus, a wild medicinal plant native to the study area. Among the isolates, Pyrenochaeta nobilis strain SFJ12-R-5 (CG
