Caracterización de bacterias asociadas a la rizosfera de plantas de yuca (manihot esculenta crantz) sometidas a estrés por déficit hídrico

Abstract

Cassava (Manihot esculenta Crantz) is one of the most important energy sources in the tropical and subtropical regions of the world. During the last years, its production has resulted in extreme environmental conditions. Plant growth promoting rhizobacteria (PGPR) are a type of bacteria that colonize the roots and a symbolic relationship with the plant, favoring their growth and resistance even in conditions of abiotic stress. In the present study, 124 bacterial components of cassava plants M. esculenta are characterized, of which 26 rhizobacteria are identified in plants over a period of 20 days. The analyzes of the abundance of the most predominant genera are: Bacillus, Achromobacter, Pseudomonas, Sphingomonas and Streptomyces. These results are important for bacterial communities such as cassava cultivation and its relationship with the response of plants to abiotic stress conditions.
