Studies in the development and cytology of Puccinia penniseti Zimm

Abstract

This paper reports the development and cytology of the pycnial and aecial stages of Puccinia penniseti on Solanum melongena and the uredial and telial stages on Pennisetum typhoides . The rust fungus follows the normal pattern, as reported for many other macrocyclic rust fungi, except in the formation of 2-celled basidium and quadri-nucleate basidio spores. The number of nuclear divisions in the basidium and basidiospores is three instead of two resulting in eight daughter nuclei instead of four.
