“…RNA synthesis inhibitors added after 7 h had no effect on conidiation. Protein synthesis inhibitors have also been shown to inhibit conidiation (Betina & Zajacová, 1978b). Together, these results clearly demonstrate that de novo transcription and translation are required during photoconidiation from at least 3 h and up to 7 h post light exposure.…”

2Lincoln Ventures Limited, PO Box 133, Lincoln University, Lincoln 7647, New Zealand Trichoderma spp. have served as models for asexual reproduction in filamentous fungi for over 50 years. Physical stimuli, such as light exposure and mechanical injury to the mycelium, trigger conidiation; however, conidiogenesis itself is a holistic response determined by the cell's metabolic state, as influenced by the environment and endogenous biological rhythms. Key environmental parameters are the carbon and nitrogen status and the C : N ratio, the ambient pH and the level of calcium ions. Recent advances in our understanding of the molecular biology of this fungus have revealed a conserved mechanism of environmental perception through the White Collar orthologues BLR-1 and BLR-2. Also implicated in the molecular regulation are the PacC pathways and the conidial regulator VELVET. Signal transduction cascades which link environmental signals to physiological outputs have also been revealed.

“…3). As might be expected, protein synthesis inhibitors also block conidiation (Betina & Zajacová, 1978). In early studies it was shown that light-induced conidiation is inhibited in hyphal cells which develop in the absence of oxygen (Gutter, 1957).…”

“…This developmental programme can be divided into a determination state and a morphogenetic stage that includes reprogramming of gene expression, and the appearance of the corresponding physiological and morphological changes. Accordingly, the operation of this programme can be suppressed using RNA synthesis inhibitors, once it has been triggered by light, but only in a time window of approximately 7 h after illumination (Galun & Gressel, 1966;Gressel & Galun, 1967;Betina & Zajacová, 1978) (Fig. 3).…”

“…The first indirect implication of nucleic acid involvement came from studies using the inhibitors 5-fluorouracil and 8-azaguanine (cf. GRESSEL andGALUN 1967, BETINA andZAJACOVA 1978). Fluorouracil and azaguanine completely suppressed sporulation with hardly measurable effects on growth.…”
