查询词典 callose

Petals (4 or)5, yellow, orange, white, or red to purple, callose or not, distinctly veined, margin usually entire.

花瓣(4或)5，黄，橙，白色，或红色到紫色，callose与否，脉，全缘的边缘通常的清楚。

Callose An insoluble polysaccaride that is laid down around the perforations in sieve plates, at wound or infection sites, and by growing pollen tubes.

callose 胼胝质：在植物筛管的筛域上存在的一种由不溶性的多糖物质积聚而形成的结构。

Two genes, PEN2 and PEN3, are also necessary for resistance to pathogens and are required for both callose deposition and glucosinolate activation, suggesting that the pathogen-triggered callose response is required for resistance to microbial pathogens.

PEN2和PEN3两个基因对于抵抗病原体也是必要的，胼胝质的沉积和芥子油甙的激活都需要由这两个基因来完成。这表明病原体激发的胼胝质应答对于抵抗病原微生物是必要。

The results showed that: different concentrations of sucrose and boric acid had significant impact on pollen germination, but different concentrations of calcium had no significant impact on pollen germination. It was most appropriate for tube elongation when sugar 150 gL^(-1) and boric acid 100 gL^(-1). Lack of sucrose would lead to the accumulation of callose in top of pollen tube and hold back its growth. The distribution of callose was regular in pollen tube when the medium lacked boric.

结果表明：蔗糖、硼酸浓度间对花粉萌发有显著影响，钙浓度间对花粉萌发的促进作用不明显；蔗糖150 gL^(-1)、硼酸100 mgL^(-1)时最适宜花粉管伸长；蔗糖的缺乏会导致胼胝质在花粉管顶端积累，使其生长停滞，缺硼时胼胝质在花粉管内分布正常。

When pollen germinates on a stigma the growing pollen tubes deposit callose as small plugs, but if the plant is self-incompatible, tubes from its own pollen will deposit more callose, which then blocks the tube, preventing fertilization.

当花粉在柱头上萌发时，生长的花粉管产生少量胼胝质，但如果该植物是自交不亲和的，那么花粉管将产生比较多的胼胝质，可以阻塞花粉管来阻止受精。

Stem leaves in whorls of 4, shorter petiolate; leaf blade oblong, sometimes ovate, to 3 X 1.4(--2) cm, pinnatisect; segments ca. 10 pairs, lanceolate, pinnatipartite, dentate, teeth callose.

在4轮生，短叶柄里的茎生叶；叶片长圆形，有时卵形，对3 X 1.4(-2)厘米，羽状全裂；约的裂片10 对，披针形，羽状深裂，具牙齿，齿callose。

Leaf blade membranous, elliptic to ovate, margin serrate, teeth not callose; inflorescences 7-10 cm, racemose

叶片膜质，椭圆形到卵形，边缘有锯齿，齿而不是callose；花序7-10厘米，总状 27 Maesa tenera 软弱杜茎山

Callose staining with particular fluorescence dye-Aniline blue indic-ated that the degradation of callose was delayed.

利用胼胝质特异性荧光染料甲基蓝对花药进行染色，表明突变体胼胝质降解延迟，导致小孢子不能从四分体中释放出来，最终没有花粉粒的形成。

Outer staminodes 2, obovate, staminode tube longer than corolla tube; callose staminode wholly callose, not petaloid at apex.

外部退化雄蕊2，倒卵形，退化雄蕊筒部长于花冠筒；胼胝质退化雄蕊完全胼胝质，并非瓣状在先端。

Plants reddish hirsute; branchlets angular; inflorescences glomerate or paniculate, rarely to 4 cm; leaf blade apex cuspidate, margin serrate or dentate, teeth callose

植株带红色的具粗毛；小枝具角花序团集的或圆锥状，很少对4厘米；叶片先端骤尖，边缘有锯齿或具牙齿，齿callose 9 Maesa permollis 毛杜茎山

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。
