Diversity and biotechnological potential of endophytic Actinobacteria isolated from cupuassu leaves (Theobroma grandiflorum)

Plant-microorganism relationships are crucial for maintaining and surviving bacterial and plant biodiversity. These interactions may benefit the plant, protecting it against biotrophic and necrotrophic pathogens. For instance, cacao (Theobroma cacao) and cupuassu (Theobroma grandiflorum) are Amazonian fruit trees showing relevant economic value but widely affected by Moniliophthora perniciosa, the causal agent of "witches' broom disease", leading to economic losses to producers and industry. One of the strategies used to manage this disease is developing a resistant genotype that does not present symptoms or disease features. In contrast, the plant-microorganisms interactions and potential role in protecting these cultures were not yet fully addressed. Here we describe prokaryotic DNA (metagenome) from leaves of a "witches' broom disease" resistance cupuassu genotype (clone C174) using PacBio Sequel II HiFi reads technology.
