Molecular docking analysis of β-1,4-Glucosidase from trichoderma harzianum against mycelial cell wall components of macrophomina phaseolina

The efficacy of β-1,4-glucosidase enzyme produced by Trichoderma harzianum in disrupting phytopathogenic fungus, Macrophomina phaseolina had been studied and recorded. Meanwhile, the molecular mechanisms underlying the cell wall components of M. phaseolina recognition remain elusive. Molecular docki...
