LFY-like genes play important role in plant development, when they were first isolated from mutants of Antirrhinum and Arabidopsis, they were thought to be "SAM-specific-determinating-genes", regulating the transition from inflorescence to flower meristem. However, further research revealed that LFY-like

LFY类基因在植物形态建成过程中具有重要作用，根据其突变体的特征，曾一度被认为是在花分生组织和花序分生组织中特异表达的"分生组织特征决定基因"，控制花序分生组织向花分生组织的转变。

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。

The prepared protoplasts could regenerate mycelium and produce conidium with similar pathogenecity to that of parental strains.

所制备的原生质体均能再生菌丝和具有产生与原菌株相同致病性分生孢子的能力。

The results showed that conidia were thin -walled and smooth to thick walled and verrucose; fat bodies accumulated gradually in both conidium and conidiogenous cell, and finally laid over the inner wall of conidium and disappeared in conidiogenous cell.

分生孢子发育的超微结构研究表明，分生孢子壁的发育是有个由薄而光滑到厚而有疣的过程；期间脂肪体在分生孢子和产孢细胞中不断累积，最后脂肪体沿着内壁排列成一层。

In higherplants,the development of flower is a very complex process,which involves thetransition from vegetative tissueto floral tissue,themorphogenesis of flower and the development and differentiation of gametocyte.

在高等植物中，花的发育是一个非常复杂的过程，涉及到由营养分生组织向花分生组织的转变，花的形态建成以及雌、雄配子体的发育和分化。

In order to understand the biology of apple ring spot fungi further and solve the problem of less conidiophores generated during their inducing culture in vitro, it was studied that the effect of culture medium pH, incubation temperature, light sources, and light regiment on growth of mycelia and generation of conidiophores, and the removing of mycelia on generation of conidiophores.

为进一步了解苹果轮纹病菌的生物学特性，解决其在离体培养条件下产生分生孢子很少的问题，研究了培养基pH值、培养温度、光源和光照条件对菌丝体生长和分生孢子发生的影响以及刮除菌丝体对分生孢子发生的影响。

The feasibility of the protoplast mutagenesis for increasing productivity was studied on a Claviceps paspali strain, which was not easy to produce conidia under laboratory conditions.

为了提高在一般条件下不易产生分生孢子的雀稗麦角菌的产碱率，对原生质体诱变育种的条件和方法进行了探讨。

After the microscope through the cultivation of detection, slender hyphae, bifurcation, and short stem hyphae collateral for its health or the alternate on the branch, the branch can continue to branch, forming two, three branch , is the end of vase-shaped branching stems, spores observed liquid spherical sporangium producers body, the formation of conidia oval eggs, smooth-walled.

通过培养后显微镜观察检测，菌丝细长、分叉多，梗为菌丝的短侧枝，其上对生或互生分枝，分枝上又可继续分枝，形成2级，3级分枝，分枝末端即为瓶状梗，孢子液制片观察到球形孢子囊体，分生孢子卵形成椭圆形，壁光滑。

Using the technique of culturing shoot apex under aseptic conditions, we found that there is a sensitive stage for the sex expression of earlier flower buds, this stage is located before the second leaf full expansing.

利用黄瓜茎尖离体培养系统结合生物切片技术观察了黄瓜早期发育阶段中成花分生组织的发生及发育情况，结果表明：就黄瓜早期发育的花芽而言，可能存在着一个性别决定的敏感点，而这个敏感点位于第二片真叶展开前的某个阶段，此时的花芽绝大多数尚处在花分生组织阶段。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
