The Structural and Functional Diversities of Bacteria Inhabiting Plant Woody Tissues and Their Interactions with...

In recent studies, the bacterial and fungal communities associated with plant wood have received considerable attention. Due to microorganisms' vertical migration from roots to leaves, these communities provide critical links between the rhizosphere and phyllosphere microbiome. Recent investigations have shown that anatomical and chemical wood characteristics shape the microbiota inhabiting living or dead wood tissues, leading to variation in the observed decomposition of these materials. Despite the fact that bacteria have limited ability to degrade polymeric lignocelluloses compared to fungi, those inhabiting wood tissues have demonstrated a significant role in these habitats. Bacteria and fungi coexist in wood and form differing relationships with each other, with consequences for community structures that, in turn, impact plant health. The aim of this review is to present an overview of current insights regarding bacterial profiles and functions in lignocellulosic plants and their interaction with fungal communities colonising the same habitat. A better understanding of plant-bacteria-fungi interactions will allow for better exploitation of these tripartite interactions and possibly improve plant health.
