Quantitative RT-PCR results showed that HTF1 is involved in the conidiation pathway,Htf1 mutant is not de-repressed in conidiophore development under non-conducive conditions.The observed phenotype of enhanced conidiophore development in the htf1 mutant may result from its defect in conidium development.It is possible that some feedback signal from conidia may inhibit further conidiophore development in M.grisea.
定量RT-PCR的结果也表明HTF1参与产孢信号途径。htf1突变体在不利于产孢条件下并没有去抑制分生孢子梗的发育,因此htf1突变体产生比野生型菌株数量更多的分生孢子梗可能是由于其无法形成分生孢子的原因导致的,这也似乎预示了在稻瘟病菌中很有可能存在一些来自分生孢子的反馈信号以进一步抑制分生孢子梗的发育。

Biological characteristics of the pathogen and the resistance of 13 cultivars of tea plant to tea brown blight were studied by means of natural infection in the field and artificial inoculation in vitro. Resistant cultivars and susceptible cultivars of tea plant were divided. And the resistance mechanism was researched tentatively. The findings are as follows: 1 Some biological characteristics of the pathogenic fungus The experiment result showed: the optimum temperature for the growth of fungus mycelium was from 24 to 27℃, the optimum temperature for sporulation ranged 22 to 30℃. Treated at 54℃ in 10 minutes, the spores didn't germinate. The optimum pH for the growth of the mycelium was 5.1~5.9, the optimum pH for sporulation ranged 5.0~6.0. Light had no much effect on the growth of fungus mycelium, but had much effect on the reproduction of the spore.
