Amino acids in the mycelium of four isolates of Macrophomina phaseolina pathogenic to groundnut (Arachis hypogaea L.)

Single hyphal tip cultures of Macrophomina phaseolina, isolated from the lesions on pegs, pods, roots and stems of naturally infected groundnut plant, were analyzed for amino acid composition of the mycelium. The isolates varied, both qualitatively and also quantitatively in the composition of amino acids, both free and bound forms.
