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。

Between the 60th and 72th hour, many oocysts emerged. Inoculated by the C. parvum -infected cell culture supernatant at the 48th hour, the immunosuppressed mice became infected.

The spore germination and gametophyte development of 21 ferns are studied. It indicates that :① the development period of prothallium and young sporophyte of the same species is different due to seeding time of spores;② the optimal temperatures of spores germination and gametophyte development of 21 ferns are about 15 -24 ℃;③ the rate of spore germination of rare ferns is much lower than the ferns which occur large populations in nature;④ the treatment with GA 3 can accelerate the germination of the spores;⑤ the prothallium changes from large to small, green to yellow when young sporophyte comes out. The prothalliums of all 21 ferns die away after the appear of the 3rd leaf of sporophytes;⑥ shapes of the 1st and 2nd leaves of the young sporophyte are different from those emerged later;⑦ spores cultured in dark can not germinate;⑧ a prothallium can develop only one young sporophyte though it has many archegoniums, and the spore propagation with leaf mould substrate is an economical method.
摘 要:以腐叶土为培养基质,对 21 种蕨类植物进行了孢子萌发和原叶体发育的研究,结果表明:①不同时期播种的同种蕨类的孢子,发育出原叶体和幼孢子体所历经的时间长短不同;②孢子萌发和配子体生长发育的适宜温度约为 15 ~ 24 ℃;③稀有蕨类的孢子萌发率低,而在野外能形成较大种群的蕨类的孢子萌发率高;④用 GA 3 处理孢子可以促进萌发;⑤当原叶体上长出幼孢子体时,原叶体由大变小,由绿变黄, 21 种蕨类的原叶体都在幼孢子体上长出第 3 片叶时消失;⑥幼孢子体上长出的第 1 、 2 片叶在形态上与以后长出的叶不同;⑦孢子萌发需要光;⑧ 1 片原叶体尽管有多个颈卵器,但仅发育出 1 株幼孢子体;⑨利用腐叶土进行蕨类孢子繁殖是一种经济实用的繁殖方法。

Based on the tissue culture, the effect of N-phenyl-N'-1,2,3-thiadiazol-5-ylurea, 6- benzyla minoprine(6-BA) and 1-Naphthylacetic acid on spore germination, protonema develop- ment and bud differentiation in Entodon challenged was investigated in this paper. The whole process was observed and taken pictures. The results show that TDZ, 6-BA and NAA have no significant effect on the spore germination. During the process of protonema development, 1.0 mg/L NAA can promote the primary development of protonema significantly, and 0.4 mg/L TDZ promotes branches formation in inter- mediate stage of the protonema development.
