1. Histone modification plays a key role in the regulation of gene expression. Acetylation by histone acetyltransferas (HATs) is normally correlated with incread gene activity, whereas deacetylation via histone deacetylas (HDACs) is often associated with gene repression.
1.组蛋白修饰在基因表达调控中起着关键作用。被组蛋白乙酰转移酶类(HATs)乙酰化的组蛋白通常与基因活性的增加有关,而通过组蛋白脱乙酰基酶类(HDACs)去乙酰化的组蛋白常常和基因阻遏有关。
晚上失眠吃什么好才利于入眠2. The spatial expression pattern of rice HDACs genes indicated that some HDAC genes have different expression profiles. Furthermore, our analysis indicated that expression of HDA705, HDT701, and HDT702 could be affected by salicylic acid, jasmonic acid or abscisic acid. The results indicate that different HDAC genes have distinct expression patterns and members of rice HDAC families may be involved in plant respon to environmental stress.

2.水稻HDACs基因的时空表达模式表明某些HDAC基因具有不同的表达谱。此外,我们的分
析表明HDA705,HDT701,和HDT702的表达可以被水杨酸,茉莉酸或者脱落酸所影响。这些结果表明不同的HDAC基因具有独特的表达模式而且水稻HDAC家族成员可能参与了植物的环境胁迫反应。
3. Calcium plays a crucial role as a cond mesnger in mediating various defen respons under environmental stress. In vivo targeting experiment revealed that Calcineurin B-like 8(OsCBL8茶道精神)localized to the plasma membrane, which was consistent with OsCBL4 and SOS3 previously reported. The OsCBL8-overexpressing transgenic rice edlings which were generated by the Agrobacterium小满节气的含义是什么-mediated approach were showed more tolerance to salt stress than non-transgenic edlings.

3.钙作为第二信使在介导多种环境胁迫下的防御反应起着重要作用。在体内定位实验揭示了
钙调磷酸酶B8(OsCBL8)定位在原生质膜上,和之前报道的OsCBL4和SOS3一致。通过农杆菌介导法产生的OsCBL8-超表达转基因水稻幼苗显示出相比非转基因幼苗对盐胁迫具有更多的耐受性。
4. 潜规则的意思This analysis has revealed that the expression of Arabidopsis and maize COB gene family members is highly developmentally and spatially regulated at the tissue and cell type-specific level, that gene superfamily members show overlapping and unique expression patterns, and that only a subt of gene superfamily members act in respon to environmental stimuli.
这个分析揭示了拟南芥和玉米COB基因家族成员在组织和细胞特异性水平上的表达受到高度发育特异性和时空特异性的调控,这个基因超家族成员显示了重叠和单一表达模式,而且只有一个基因超家族的亚级成员对环境刺激作出反应。
5. To identify candidate grapevine NAC genes with a role in respon to stress, publicly available microarray data were obtained to calculate their expression change under abiotic and biotic treatments, with a number of VvNAC genes displaying up-regulation after stress induction. Therefore, this study has uncovered more knowledge relating to the gene structures, chromosome organizations, evolution, expression profiles and functions of VvNAC genes.
为了鉴定对在胁迫中具有反应的候选葡萄NAC基因,我们取得了公开可用的微阵列芯片数据去计算它们在非生物和生物处理下的表达量的改变,由于一部分VvNAC基因在胁迫诱导后显示为上调表达。因此,本次研究揭露了更多关于VvNAC基因的基因结构,染色体组,进化,表达谱和功能的知识。出尔反尔
6. FT caus early flowering with determinate inflorescence in Arabidopsis thaliana (L.) and belongs to a small flowering gene family. We have also reported the FT homolog of PmFT, suggesting that it relates to monocarpic mass flowering and inflorescence architecture.
6.在拟南芥中FT基因造成了早期开花和有限花序而且属于一个小开花基因家族。我们也报道了和FT基因同源的PmFT,表明它和结一次果的大规模开花和花序结构有关。
无缘无故的反义词7. The (Leu) zipper (bZIP) proteins characteristically harbor a bZIP domain compod of two structural features: a DNA-binding basic region and the Leu zipper dimerization region. They have been shown to regulate diver plant-specific phenomena, including ed maturation and germination, floral induction and development, and photomorphoge
nesis, and are also involved in stress and hormone signaling.
7.赖氨酸拉链(bZIP)蛋白典型地包含一个bZIP结构域,这个结构域由2个特殊结构组成:一个DNA结合基础区域和亮氨酸拉链二聚化区域。它们被显示出调控多种植物特异性现象,包括种子的成熟和萌发,花的诱导和发育,和光形态发生,而且也参与了胁迫和激素信号转导。
8. Overexpression of VvTFL1A does not affect flowering time but the determination of flower meristems, strongly altering inflorescence structure, which is consistent with the biological roles assigned to similar genes in other species.
8.VvTFL1A基因的超表达不影响花期但是影响花分生组织的决定,强烈改变花序结构,和对比过的其它物种的相似基因的生物学功能一致。
9. The complete alignment of PEBP quences was manually edited using BioEdit 5.0.9 version. The phylogenetic relationships of nucleic quences were investigated using neighbor-joining (NJ), maximum parsimony (MP), maximum likelihood (ML), and Bayesian inference (BI) methods.
9.完整的PEBP序列对比通过使用BioEdit 5.0.9版本被手动编辑。核苷酸序列的进化关系通过使用邻接法(NJ),最大简约法(MP)最大似然法(ML),和贝叶斯推理(BI)进行调查。
10. Amino acid uptake into cells and cellular compartments depends on membrane-integral transporter proteins, and amino acid transporters have been identified in many organisms. In Arabidopsis the amino acid permeas (AAP)family consists of eight members(AtAAP1-8) that generally transport neutral and acidic amino acids with moderate affinity, with the exception of AtAAP3 and AtAAP5 that also transport basic amino acids.
