Abstract

Entomopathogenic fungi are an important factor in the natural regulation of arthropod populations. Moreover, some can exist as an endophyte in many plant species and establish a mutualistic relationship. In this study, we have investigated the endophytic growth of Beauveria bassiana within different tissues of Phaseolus vulgaris in the presence and absence of Tetranuychus urticae. After the colonization of the B. bassiana within the internal tissues of P. vulgaris. The susceptibility of T. urticae appeared to depend on the life stage where high, moderate, and low mortalities were recorded among adults, nymphs, and eggs, respectively. In addition, this study provided, for the first time, molecular insight into the endophytic growth of B. bassiana by analyzing the expression of several genes involved in the development of the entomopathogenic fungi at 0-, 2-, and 7- days post-inoculation. B. bassiana displayed preferential tissue colonization within P. vulgaris that can be put into the following order based on the detection rate: leaf > stem > root. After analyzing the development-implicated genes (degrading enzymes, sugar transporter, hydrophobins, cell wall synthesis, secondary metabolites, stress management), the most remarkable finding is the detection of behavioral change between parasitic and endophytic Beauveria during post-penetration events. This study elucidates the tri-trophic interaction between fungus-plant-herbivore.
