NUCLEAR BEHAVIOUR DURING TELIOSPOSE GERMINATION IN USTILAGO TRITICI AND U. NUDA
Abstract
When germinated upon water, the mature teliospores of Ustilago, tritici and U. nuda gave rise to 4 celled monokaryotic promycelium. Nuclei moved from adjacent promycelial cells into a conjugation tube . The conjugation tube elongated into a branchis monokaryotic or dokaryotic mycelium. The haploid number of chromosomes appeared to be a 4. The growth of these two smut fungi on potato dextrose agar was not identical.
