Regulation of periodicity and intensity of photo-induced conidiation of Trichoderma viride
A total of 26 morphological and colour mutants of Trichoderma viride were characterized. They were divided into three groups based on morphology, pigmentation, growth rates and intensity of conidiation. Complementation analysis of colour mutants and mutants with disturbances in conidiation showed that after anastomosis and protoplast fusion only heterokaryotes are formed while no nuclear migration and diploidization takes place.
Numerous antibodies with a known mechanism of action are utilized as possible means for studying morphogenesis and differentiation. Inhibitors of biosynthesis of nucleic acids and proteins, compounds intervening with the synthesis and/or function of cell walls and membranes or compounds influencing the energy metabolism are particularly useful. The use of antibiotics for studies of the life cycle of viruses, bacteria, fungi, myxomycetes, protozoa and algae is analyzed in the present communication. Certain aspects of morphogenesis and functions of mitochondria and plastids were clarified with the aid of antibiotics. Relationships between production of antibiotics and differentiation of their producers are discussed in the final part of the paper.

The sporulating and nonsporulating mycelium of Trichoderma viride exhibited significant differences in the levels of triacylglycerols, sterol esters. fatty acids, gangliosides, phosphatidylethanolamine and sphingomyelin. Quantitative changes in the contents of polar and nonpolar lipids were observed also during the analyses of one-, two-, three-day-old sporulation zones in colonies subjected to repeated photo-induction. These findings are similar to the changes observed during the differentiation of other species of fungi.
The photo-induced conidiation of Trichoderma viride is suppressed by ethidium bromide, acriflavin, lomofungin and 8-quinolinol at concentrations which do not inhibit the colony growth of this deuteromycete.
