Abstract

CYTOLOGY of TILLETIA INDICA, the causal agent of Karnal or partial bunt of wheat, was investigated by light and fluorescent microscopy. Following meiosis and mitosis at TELIOSPORE germination, promycelia were observed multinuclate. Promycelia bear a cluster of primary filifom sporidia which initially were single, monokaryotic cells. After abstraction cell division occured, bu t each cell stayed momokaryotic. Primary sporidia were directly germinated to bear SOMATIC mycelia or bear secondry allantoid sporidia on strigmata which both monokaryotic. The promycelial, allantoid sporidial and sporogenous mycelial nuclei were subglobose or ovoid, whereas the nuclei of filiform sporidia and SOMATIC hyphae were consistently elongated. Dikarytic sporogenous mycelia isolated from infected wheat caryopses were formed TELIOSPOREs on potato dextrose agar amended with 0.1% yeast extract after 15-20 days. During TELIOSPORE formation in vitro two nuclei were migrated from sporogenous mycelia to probasidial initials which formed at right angles. The DIKARYOTIC probasidia usually were subtended by Y-shaped septa. The evidences of this study suggested that karyogamy was occured during very early stages of probasidial development because even immature TELIOSPORE were monokaryotic. Nuclear condition of TELIOSPORE formation were easily observed in cultures, but in vivo the gelatinoid nature of the mycelia in host tissue made this much more difficult.
