Abstract

+contributes significantly to the induction of yeast form from protoplast in synthetic broth and this is time related. Two distinct anamorphic patterns were induced, initialized by thallic growth and growth sphere wall lyses. Thallic growth was determinate with subtype’s production of conidia after growth cessation as in vesicular head group conidial form or enterothallic conidia and catenulate formation of conidia on same plane with short germ tube represented by holothallic conidia, as well as holoblastic conidia. The second growth pattern was proliferate, with yeast cell giving rise to daughter buds. Biomass profile exhibited 2-phases common in Na + supplemented broths with determinate thallic growth contributing proportionally to the first peak. On thallic cell wall rupture, released cytosolic units progressively convert to protoplasts and subsequently to yeast cells. Uracil supplementation eliminated determinate thallic anamorphs with morphological expression occurring as ovoid to long ovoidal, ellipsoidal and cylindrical yeast cells, which were polar, bipolar or multilateral budding. Thin tree-like branched yeasts were scanty at 100 mM uracil supplementation. The results offer new insights into the phenomenon of fungal morphogenesis. It attributed specific effects to K
