Abstract
Parasexual crosses involving a mutant of A. flavus having a high and relatively stable level of aflatoxin B1 revealed a genetic locus for control of aflatoxin synthesis. Five different diploids, each heterozygous for high aflatoxin B2 levels, accumulated low amounts of B2 but high amounts of B1. Although the haploid segregants from these diploids included a variety of aflatoxin phenotypes, one-half produced more B2 than B1 and one-half produced less B2 than B1. Five different diploids, each homozygous for high aflatoxin B2 levels, accumulated high amounts of B2 as did all haploid segregants from these diploids. A single genetic locus may control the higher aflatoxin B2 than B1 accumulation in this mutant.This publication has 2 references indexed in Scilit:
