The role of Yersiniaceae bacteria in plant disease suppression: Emerging biocontrol agents

The immoderate application of agrochemicals worldwide has led to the need to find safer disease control strategies for humans, animals, plants, and the environment. The use of microbial biocontrol agents addresses this need effectively, yet further efforts are required to expand the repertoire of microorganisms that can be developed as commercial biocontrol agents. Among these, a set of bacteria from the Yersiniaceae family has emerged as a promising option, offering both biocontrol potential and direct plant growth promotion. Genera like Rahnella, Rouxiella, and Serratia exhibit multiple mechanisms that contribute to plant health, but their role in biocontrol remains underexplored compared to other bacterial groups. This review aims to bridge this knowledge gap by examining the biocontrol capabilities, mechanisms, strengths, and areas of opportunity of Yersiniaceae bacteria, emphasizing their role in sustainable agriculture and their potential for future applications in this dynamic field.
