ABSTRACT

 

A growth defective mutant of Neurospora crassa, VU-82 was generated in the laboratory by mutagenizing conidia of well characterized strain of N. crassa (FGSC 2489) using Ethyl Methane Sulfonate (EMS) as mutagen. This mutant (VU-82) has slow growth rate (2.9 mm/h), shows predominant dichotomous branching, bursting of tips, hyperbranching and has irregularities in hyphal wall. Genetic studies show that these defects are heritable and are controlled by a single nuclear gene. This mutant may help in understanding mechanisms of branching and tip growth in fungi.
