constitutive gene

The SR 1 gene was constitutive gene with low abundance in soybean genome.

RT-PCR技术对该基因的转录表达情况研究表明，SRI基因在大豆中为低丰度组成型表达，其表达不受病原菌接种和水杨酸的诱导，并无组织特异性。

Constitutive promoter was widely used in plant stress resistance genetic engineering to improve stress tolerance of transgenic plants. But constitutive expression of exogenous gene influences plant growth and even leads to infertility.

在植物抗逆基因工程中，组成型启动子已经被广泛应用，虽然组成型启动子驱动外源基因表达可以提高转基因植物的抗逆性，但会导致转基因植物生长迟缓甚至不育。

COX-1 is the constitutive gene, whereas COX-2 is inducible gene. Cytokines, growth factors, oncogenes, and tumor promoters have been found to induce COX-2 up-expression in order to produce prostaglandins ( PGs) for various inflammatory stimulation.

COX-1为组成性基因，COX-2是诱导型基因，受细胞因子、生长因子、癌基因、及肿瘤促进剂的刺激，COX-2表达上调，使其产生对各种炎症做出反应的前列腺素类物质（PGs）。

Constitutive expression of the gene led to taxadiene accumulation, but the A.thaliana plants showed growth retardation and decreased levels of photosynthetic pigment.

是紫杉得意积累，但A。拟南芥植物表现出生长迟缓和光合色素水平减少。

Objective: To investigate the constitutive gene expression of chemokine binding protein D 6 in breast cancer and its regulation by interleukin-1 ( IL-1)β.

目的研究CC族趋化因子结合蛋白D6在乳腺癌中的组成性表达及细胞因子IL-1β诱导后D6表达的改变。

Constitutive expression of B-actin gene was used as external control to monitor the beginning amounts of RNAs from two kinds of tissues.

以组成型表达的β-actin基因为外对照，对两类组织来源的起始RNA量进行监测；
