Which bacterial phylum typically demonstrates the highest prevalence in the endophytic microbial communities associated with halophytic plants?

💡 Explanation:

Proteobacteria is frequently the most abundant phylum in plant-associated microbial communities. In studies analyzing endophytic bacteria in halophytes (salt-tolerant plants), Proteobacteria were found to be the most prevalent group, often followed by Firmicutes and Actinobacteria.
