Female gametogenesis in higher plants undergoes various developmental changes, including the de novo formation of germline cells, the differentiation of the megaspore mother cell, meiosis, megaspore selection, and the development of the embryosac.

高等植物雌配子体的形成涉及孢原细胞和大孢子母细胞的确立与分化、大孢子发生、功能大孢子以及胚囊的形成和发育等多种复杂调控过程。随着当代生物技术及功能基因组学的发展，近年对雌配子体发育的研究已从细胞学描述逐渐过渡到对基因和发育调控分子机理的探索。

The effects of microbial inoculant on humification and humus qualityare studied.The results show that inoculating Phanerochaete chrysosporiumin second fermentation phase of composting could promote the formation ofhumus,increase the humus content,and reduce the humification time by 7days.

通过考察接种微生物对堆肥腐熟程度及成品腐殖质含量的影响，发现在堆肥二次发酵阶段接种黄孢原毛平革菌能优化控制腐殖质的形成，提高了总腐殖质含量，增强了堆肥成品的腐熟程度，并使堆肥腐熟时间缩短了7d左右。

The development of anther and ovule followed the finish of the flower organ initiation. Pollen mother cells and well developed microsporagium wall occurred when the diameter of the bud reached about 3.0 mm, and the archesporial cell which played the role of megaspore mother cell formed in ovule when the diameter of the bud reached about 3.5 mm.

花药及胚珠的发育与花器官的形态发生之间有明显的连续性，当花蕾直径为3.0 mm左右时花粉母细胞及完整的花粉囊壁形成，直径达到3.5 mm左右时胚珠中出现孢原细胞的分化，它直接起大孢子母细胞的功能。

In the functional cell such as archesporial cell,megasporocyte,dyad,tetrad and youngmegaspore,among which the three cells close to micropyle end do not degeneratewholly,no clear starch grains were observed as well as in the embryo sacs from singlenucleate embryo sac to 8-nucleate one just forming.

淀粉粒变化有规律性，在孢原细胞、大孢子母细胞、二分体、四分体和早期的大孢子（即四分体中近珠孔端的3个细胞未完全退化）等功能性细胞中未观察到明显的淀粉粒。

The archesporial cell lies under the nucellus epidermis, which develops into a functional megasporocyte.

孢原细胞位于珠心表皮之下，直接起大孢子母细胞的功能。

The effect of glucose concentration was also tested in repeated-batch mode. After domestication, the percent of decolorization to Safranine T increased from 36% to 89% in six days.

实验还表明，对黄孢原毛平革菌进行诱导驯化后再处理难降解染料番红花红，可使6d的脱色率从36%提高到89%。

Mutation breeding of Phanerochaete chrysosporium by UV-light and nitrite was investigated, and the capability of decolorization to Safranine T and dye of high concentration after induced mutation was tested..

通过紫外线照射和亚硝酸盐两种诱变手段对黄孢原毛平革菌进行了诱变育种实验，进而考察了诱变后筛选出的优势菌对高浓度染料、番红花红的降解情况，并以此对比评价了两种诱变方法的诱变效果。

Microscopic observation on anther development process of cytoplasmic male sterile line"1815A"showed that its anther development was inhibited at the stage of archesporial cell differentiation.

以1815A不育系对应的保持系1815B作对照，对不育系进行细胞学观察，结果表明：随着花蕾的发育，败育的雄蕊一直处于孢原细胞时期，不能形成花粉囊并产生花粉母细胞，但雌蕊和维管束组织发育正常。

Eleven subcloned DNA fragments from the 5′- upstream region of lipA, lipC and lipF of Phanerochaete chrysosporium were assayed by using the gel mobility shift assay. The total proteins extracted from P.chrysosporium mycelia grown in Kirk medium and natural fir wood chip were used to identify the segments in these 11 DNA fragments which are controlled by some regulatory proteins.

用DNA-蛋白质体外结合实验和凝胶迁移率变动分析技术筛选黄孢原毛平革菌木质素过氧化物酶基因lipA、lipC、lipF的5′-端调控区内能与该菌在木质素降解条件下形成的蛋白特异结合的顺式作用元件。

Vanillic acid ,ferulic acid,and p-hydrobenozic acid by using Phanerochaete chrysosporium.

研究黄孢原毛平革菌(P.chrysosporium)对香草酸、阿魏酸、对羟基苯甲酸的降解作用。

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。
