胼胝质

Relative root elongation, Al content and callose content in root tips and hematoxylin staining were compared in evaluating plants' tolerance of Al stress.

利用相对根伸长率、根尖Al含量和根尖胼胝质含量等三项参数结合苏木精染色法，研究Al胁迫下，各参数在评价植物耐Al性上的地位，以及各参数间的相互关系。

The perception of pathogen or microbe-associated molecular pattern molecules by plants triggers a basal defense response analogous to animal innate immunity and is defined partly by the deposition of the glucan polymer callose at the cell wall at the site of pathogen contact.

植物对病原体和微生物相关分子模式的感应，可激发基础防御应答的产生。这类似于动物的先天免疫功能，并且通过细胞壁上病原体连接位点的葡聚糖聚合物胼胝质的沉积，得到了部分的证实。

Later on,the opened sieve plate was formed because of callose autolyzing after the protoplasm disappeared completely.Ultimately,the physiological function of SE was lost.

在筛管原生质完全降解消失后，筛板处的胼胝质自溶，最后形成具开放筛孔的筛板，至此筛管完全失去功能。

The tetrasporophyte wrapped by callose is of simultaneous type.

四分体呈四面体型，被胼胝质壁包围。

Synchronously,the callose appeared in sieve plate,and P-protein was disaggregated.

后期筛板上产生胼胝质，筛管内P-蛋白质解体。

The expression of AtPP2like gene(lec17 and lec26)in Cucumis melo determined by RT-PCR and the callose deposition in phloem measured by aniline blue staining were both induced by HrpNEa.

利用反转录PCR的方法，检测了甜瓜两个AtPP2类似蛋白的编码基因lec17和lec26，受到HrpNEa的诱导表达增强，同时通过苯胺蓝染色鉴定了胼胝质在HrpNEa处理的甜瓜植株中沉积增加。

The expression of AtPP2like gene (lec17 and lec26) in Cucumis melo determined by RT-PCR and the callose deposition in phloem measured by aniline blue staining were both induced by HrpN.

利用反转录PCR的方法，检测了甜瓜两个AtPP2类似蛋白的编码基因lec17和lec26，受到HrpN的诱导表达增强，同时通过苯胺蓝染色鉴定了胼胝质在HrpN处理的甜瓜植株中沉积增加。

Staining with the improved carbol fuchsin-aniline blue fluorescence method is a convenient and efficient way to observe the behavior of the callose wall of microspore mother cells during meiosis.

利用改良苯酚品红－苯胺蓝压片法，观察小孢子母细胞减数分裂过程中胼胝质的动态变化。

Staminode tube usually short; staminodes white, occasionally tinged or marked with purple; outer staminodes 2, petaloid, obovate, exceeding corolla lobes; cucullate staminode with median or subterminal appendage; callose staminode obovate, apex petaloid.

退化雄蕊管通常短；退化雄蕊白色，偶尔微染或者用紫色标明；外部退化雄蕊2，瓣状，倒卵形，超过的花冠裂片；兜状的退化雄蕊有中间或者近顶生附属物；胼胝质退化雄蕊倒卵形，先端瓣状。

The cortical cells had thin walls and mitochondrium, and nucleus wassurrounded by chloroplasts, and vesicles were next to cell plasmalemma. However, cellwalls of velamen, cortex and exodermis in the mycorrhiza of D. nobile had ring orpapillary thickenings in many cases. The hyphae were surrounded by moremitochondria and vesicles of plant, and the hyphae were digested and their structure waschanged at last. The cell wall of endodermis also had typical ring thickenings, and manysieve orifices in sieve tube elements of phloem were covered by callose, while therewere liaison cords in a few sieve orifices.

金钗石斛菌根的根被细胞的细胞壁多处出现环形圈，外皮层细胞壁加厚，木质化，也有环形圈存在，皮层细胞细胞壁多角形明显，加厚，皮层细胞中存在被消化、失去结构的真菌菌丝，在菌丝周围有较多的线粒体、小泡，内皮层细胞的细胞壁呈现的典型的加厚及木质化环形圈，韧皮部筛管的筛板结构，绝大多数筛孔已为胼胝质所覆盖，仅个别筛孔中还存在连络索。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
