Endophytic interaction of Bacillus sp. in micropropagated banana plantlets

Abstract

The banana tree is associated with different species of endophytic bacteria that can stimulate plant growth. However, further studies are needed to better understand the relationships between this group of bacteria and the host plant. The objective of this study was to investigate the localization of the EB-40 (Bacillus sp.) through anatomical and ultrastructural analyses in micropropagated banana plantlets. The results demonstrated the effective colonization of the EB-40 isolate in the intercellular and intracellular spaces, as well as in the rhizosphere region. The wall of endophytic bacteria contains calcium and nitrogen. The EB-40 isolate was also observed to associate with the plasma membrane and cell wall. These results further our understanding of the mechanisms involved in the colonization of plant cells by endophytic bacteria in micropropagated banana plantlets.

The antagonistic mechanism of rhizosphere microbes and endophytes on the interaction between banana and Fusarium oxysporum f. sp. cubense

“…in banana plant tissues by light and transmission electron microscopy resulted colonization in intercellular and intracellular spaces, rhizoplanes and root hairs. There was also close association between bacterial cells and plant cell walls [69]. Root hairs were the first point to colonize by fluorescently labelled endophytes and then root cortex, xylem and finally colonize various plant parts and organs.…”

Diversity and functional characterization of endophyticMethylobacteriumisolated from banana cultivars of South India and its impact on early growth of tissue culture banana plantlets

“…Previously banana endophytes belong to the phyla Actinobacteria, Firmicutes and Proteobacteria were isolated by many researchers (Karthik et al 2017;Su et al 2017;Rocha et al 2019). This study investigated the endophytic cultivable diversity and plant growth promoting traits of leaf associated Methylobacterium species from the field grown banana cultivars of Tamil Nadu.…”
