查询词典 ja

JA transportation is likely to be through ray parenchyma cell, vessel tube and sieve tube in H.

JA在橡胶树内可快速通过韧皮部经由形成层径向运输到木质部，同时，JA能通过木质部和韧皮部进行纵向长距离双向运输。

Our results showed that the transportation of JA from phloem to xylem occurred mainly through ray parenchyma cells and cambium regions, and that JA could be transported rapidly upwards and downwards through vessel tube and sieve tube.

3H—JA分布在筛管、次生韧皮部的薄壁细胞和射线细胞、形成层区以及导管、次生木质部的薄壁细胞和射线细胞，其中，在韧皮部和木质部的射线细胞及筛管、导管壁周围分布最多。

Most patients' death arise from the metastatic spread of primary tumors There is an urgent need for the finding of novel anti-tumor and anti–metastatic drugs to improve the quality of life and survival rate of patents Justicia procumbens is an herb and used to reduce fever inflammation and canker in Taiwan We've detected that 0 3 μM JA could effectively inhibit the proliferation of oral cancer cells OC-2 and HSC3 but not normal oral keratinocytes in MTS assay JA-treated OC2 underwent apoptosis as suggested by increased sub-G1 DNA contents condensed nuclear morphologh and DNA fragmentiation The migration activity of OC-2 was also significantly reduced by treatment with low concentration of JA The expression of ?

大部分的口腔癌病患死於原位癌的转移和扩散，寻找有效抗癌和抗转移的药物疗法来增进病患的生活品质和存活率，对治疗口腔癌而言非常重要。爵床草是台湾民间常用草药，常被用来消炎止热和治疗口疮、乳瘤。我们利用MTS分析，发现处以0 3 μM的JA 48小时，即可有效抑制口腔癌细胞OC-2和HSC3的增生，但不影响正常口腔上皮细胞生长。OC-2经JA处理后，其sub-G1的DNA含量增加，并可观察到DNA固缩和梯度断裂的现象，说明JA可使OC-2走向细胞凋亡。除此之外，0 3 μM的JA亦可有效降低OC-2的迁移能力。

Appropriate nutrient supply could keep higher ZT content at initial stage and higher ABA, JA and IAA content and lower GA content at middle period, which could satisfy the demand of important hormones in every stage of tuberization and keep GA/ABA and GA/JA at reasonable levels during tuber formation.

而合理营养水平供给，保持了前期较高水平的ZT含量，中期较高的ABA、IAA、JA含量和较低的GA含量，保证了块茎发育各时期对重要激素的需要，GA/ABA和GA/JA在块茎发育各时期也保持在合理的水平。

Were analyzed under different nutritional levels. The results showed that in tuber development, under- or over-supply of nutrients reduced ZT content at initial stage and IAA, ABA and JA content at middle stage, but increased GA content in the whole process, which caused GA/ABA and GA/JA to be off balance in the key stage of tuberization.

结果表明，过低、过高的营养供给，降低了块茎发育前期细胞分裂素的含量，中期细胞生长素的含量以及促进块茎发育的脱落酸、茉莉酸含量，增加了各时期促进匍匐茎发生的赤霉素含量，导致在块茎形成和膨大的关键时期，GA/ABA和GA/JA比值失衡，抑制了块茎的正常发育。

It was possible that the direct transport of JA from unwounded tissue to wounded site could account for the increase of JA after leaf wounding.

用免疫荧光显微镜技术和免疫胶体金电镜技术证明JA在蚕豆叶片下表皮和气孔保卫细胞上是普遍存在的，它主要分布在保卫细胞的叶绿体、细胞核和细胞壁上；叶片的局部灼伤可提高JA在质外体和气孔保卫细胞中水平。

In summary, we identified firstly that existence and distribution of JA and NOS in guard cell; presumed that the direct transport of JA from unwounded tissue to wounded site could account for the increase of JA after leaf wounding, and involved stomatal closure, and proposed a possible pathway of JA involved in regulating stomatal movemnts as follows: The production of NO stimulated by JA triggers the increases of cytosolic Ca〓 concentration, subsequently activate other downstream reactions and eventually induces stomatal closure.

本研究中我们首次确认了气孔保卫细胞中JA和NOS的存在和分布；伤引起的JA运输和分配的变化可能参与对气孔运动的调控，并提出JA调控气孔运动信号转导的一条可能途径：JA引起NO含量的增加，经第二信使Ca〓的作用及其下游事件，最终诱导气孔关闭。

Feeding JA or ABA after root tip cutting showed similar effects with endogenous JA or ABA.

根尖切除后单独或共同饲喂JA或ABA，能表现出与内源JA、ABA具有的调控地上部叶片生理反应的相同功能。

Can reverse JA-induced migration inhibition JA-treated cells also showed significantly higher adhesion to laminin In conclusion these results indicate a novel anti-tumor role of JA via reducing reorganization of cytoskeleton increasing integrin 3 expression and adhesion ability to inhibit tumor cells migration Furthermore immunofluorescence staining of phalloidin/actin indicated that JA-treated cells exhibited cytoskeleton rearrangement and significant decreases in the number and length of filopodia Activity of Rho-family small GTPases was detected by a GST-pull down assay and showed that GTP-loaded Cdc42 and Rac were decreased in JA-treated cells In the future we hope these findings will be helpful to further understand the mechanisms underlying tumor progression in oral cancer and subsequently improve the cancer prevention and treatment

以抗体阻断integrin ？3可以有效使OC2恢复被JA所抑制的迁移能力。细胞贴附实验指出JA能提高OC-2在laminin环境下的贴附能力。当我们进一步以免疫萤光染色观察细胞，发现在JA处理下的OC-2，其外形、细胞骨架和细胞边缘的filopodia的密度和长度明显减少，利用GST-pull down assay侦测到Cdc42-GTP和Rac-GTP的表现量降低。推论爵床素A可能透过刺激口腔癌细胞大量表现integrin ？3，使细胞贴附能力增加或是透过改变细胞骨架来降低细胞迁移能力。希望本研究对於JA所做的抗癌及抗转移效应评估能提供口腔癌治疗在研发上一些帮助。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
