Table 1. Effects of oligomycins and the fungicide Nativo® WG75 on germination of conidia and morphology of germ tubes and appressoria of Magnaporthe oryzae Triticum at 0.05 μg/ml in vitro.

Compound	Time (h)	Germination of conidia, and morphology of germ tubes and appressorial formation
		Germinated conidia (% ± SEa)	Morphological change/developmental transitions in the treated conidia
Water	0	0 ± 0e	No germination
	6	100 ± 0a	Germination with normal germ tube and normal appressoria
	12	100 ± 0a	Normal mycelial growth
	24	100 ± 0a	Normal mycelial growth
Oligomycin B	0	0 ± 0e	No germination
	6	38.3 ± 0.7d	24 ± 0.9% Short germ tube and 14.3 ± 0.7% conidia lysed
	12	24 ± 0.9d	10.6 ± 0.7% Normal germ tube, 8.4 ± 0.2% short and 5 ± 0.4% Abnormally elongated germ tube
	24	0 ± 0b	No appressoria, no mycelial growth
Oligomycin F	0	0 ± 0e	No germination
	6	59 ± 0.8b	53 ± 0.4% Short germ tube and 6 ± 0.8% conidia lysed
	12	53 ± 0.4b	33.3 ± 0.5% Normal germ tube and 19.7 ± 0.2% abnormal branching at the tips
	24	0 ± 0b	No appressoria, no mycelial growth
Nativo	0	0 ± 0e	No germination
	6	50.3 ± 0.7c	Germinated with a short germ tube
	12	50.3 ± 0.7c	Normal germ tube
	24	0 ± 0b	No appressoria; no mycelial growth

^aThe data presented here are the mean value ± SE of three replicates in each compound. Means within the column followed by the same letter(s) are not significantly different from those assessed by Tukey's HSD (Honest Significance Difference) post-hoc (p ≤ 0.05). Conidia germination percent at different incubation times is not cumulative, rather at different time intervals.
