子孢子

Macrocystis and Nereocystis and is distinguished by its heteromorphic ALTERNATION OF GENERATIONS in which a large sporophyte alternates with a microscopic gametophyte, and in which growth takes place in a special meristem region on the surface of the thallus.

在这类植物的生活史中，孢子体比配子体小。配子体是由叶状体表面特殊的分生组织区发育而来的。

Antheridium formation was not promoted when young gametophytes of C. podophylla were treated with their own mature gametophytes or those of Pteridium aquilinum Kuhn, Lygodium japonicum Sw., or Ceratopteris thalictroides Brongn. Their spores did not germinate at all in dark conditions. These results indicate that there is no antheridiogen (and possibly no germinin, either) in this species.

鬼桫椤之幼配子体并未受到蕨、海金沙、水蕨及其本种之成熟配子体影响而促进其藏精器的产生，其孢子亦未在所有处理之黑暗环境中发芽，此结果显示本种不产生促精素。

A large mult in ucleate spore formed by union of similar gametes,as in algae or fungi.

接合孢子由相似的配子结合而成的多核大孢子，如在海藻或真菌中

A large multinucleate spore formed by union of similar gametes,as in algae or fungi.

接合孢子由相似的配子结合而成的多核大孢子，如在海藻或真菌中

The study focused on sequence feature, molecular evolution of 16SrRNA gene of Nosema bombycis, and therefore the PCR method to detect pebrine of Bombyx mori eggs was created.

以家蚕微孢子及带毒蚕卵为材料，研究家蚕微孢子虫16SrRNA基因的序列特征、分子进化以及成品卵家蚕微粒子病的PCR检测方法。

The cells ovoidal, while budding the wall structure is entroblastic. Reproduction by multilateral budding. It is not form ascospores or ballistospores; on malt agar red carotenoid pigments is synthesized.

该菌株细胞卵圆，出芽时胞壁结构为内分芽型，多端芽殖，不产生子囊孢子和掷孢子；在麦芽汁琼脂上产生红色胡萝卜素，颜色反应阳性，菌落平滑，有光泽，质地软而呈粘液状，不发酵任何糖，能同化麦芽糖、蔗糖、乳糖、棉子糖、松三糖和硝酸钾，能分解尿素；细胞水解物中含甘露糖、葡萄糖和半乳糖。

Light microscope was employed to observe spore germination, protonemal development, gametophyte differentiation of Ptychomitrium sinense indoor cultured. The results showed that in P.

：通过室内人工培养中华缩叶藓的孢子，在光学显微镜下详细观察了其孢子萌发、原丝体发育及配子体发生的全过程。

A ring or group of thick-walled cells around the sporangia of many ferns that functions in spore release.

卵孢子一种受精的雌性细胞或合子，尤指异配生殖产生的一种休眠孢子

Seven species of Phellinidium were reported from China. Phellinidium fragrans from Changbaishan Nature Reserve, northeastern China is newly reported for China and is characterized by its resupinate and perennial basidiocarps with fragrant odour, smallest basidiospores in the genus, and the presence of conidia in the subiculum.

小木层孔菌属的种类在我国共有7种，其中芳香小木层孔菌Phellinidium fragrans为中国首次报道，该种发现于吉林省长白山自然保护区，与同属其它种的区别是子实体多年生、平伏、具有芳香气味，其担孢子在同属的种类中最小，菌肉中具有形状不规则的厚垣孢子。

Null mutant Δmnh6 produced appeared offwhite hyphae, showed reduction in growth, conidiation and appressorium formation, and also showed reduction in appressorium turgor pressure. And the hyphae were more readily wettable by a solution containing SDS and EDTA and more easily digested by fungal cell-wall-digesting enzymes. The appressoria produced by Δmnh6 mutants showed diminished host penetration and the infectious hyphae of Δmnh6 mutants showed reduced in planta growth. Targeted deletion of mnh6 resulted in the greatly reduced virulence capacity to barley and rice CO39 in infection assays.

突变子Δmnh6的菌落形态不同于野生型GUY11，菌落呈灰白色，菌丝稀疏，生长速度变慢，产孢菌丝细胞壁的溶剂疏水性消失，菌丝细胞壁容易被细胞壁降解酶降解，产孢减少，孢子形态变得细长，孢子的附着胞形成率降低，附着胞的膨压降低，附着胞对寄主植物表面的穿透能力减弱，侵入后生长速度减慢，喷雾接种后对大麦和水稻CO39的致病性消失。mnh6基因重新引入Δmnh6后，突变子的表型恢复。
