油菜

The insoluble form of myrosinase presented low activity in three tested organs, including seeds, cotyledons and leaves.

而在油菜种子中，芥子酶主要以结合形式存在，在子叶和真叶中，芥子酶则主要以可溶形式存在。

The myrosinase gene was amplified from total RNA by RT-PCR and inserted into Escherichia coli expression vector pGEX-4T-1.The result of sequencing was EF583560 in GenBank.

实验通过RT-PCR程序从提取的油菜总RNA中扩增出硫代葡萄糖苷水解酶（又称黑芥子酶，EC3.2.1.147）基因，酶解后插入大肠杆菌表达载体pGEX-4T-1，获得克隆菌株。

It was observed by means of electronic microscope that toxinresulted in the apparent change in ultrastructure of rapeseed leafincluding the damage of chloroplast membrane,dilated,disorderedgrana lamellae;the damage of mitochondria membrance andeventually vacuolated mitochondria;the contract of cell nuclein.

电镜观察发现：菌核菌产生的毒素引起油菜叶片超显微结构显著变化，主要包括叶绿体膜破坏，基质片层肿胀，排列紊乱，形成空腔，最终叶绿体解体；线粒体膜破坏，最后空泡化；细胞核质凝缩。

Rapeseed is a main oil crop worldwide and has become the third most important source of plant oil. It accounts for a considerable proportion of the cultivated oleiferous plants.

油菜是世界范围内重要的油料作物，是植物油脂的第三大来源，其种植面积和总产量在油料作物中占有相当大的比例。

SYNTHESIS OF NEW SPECIES AND CYTOGENETIC STUDIES IN OLEIFEROUS BRASSICA——II.

芸苔属油菜植物的新种合成及其细胞遗传学研究——II。

The samples of free amino acids were prepared from bee-collected pollens of codo-nopsis pilosula, brassica campestris, typha angustifilia and papaver, through extraction with ethanol-water solution and further purified by ion-exchange chromatographic columns.

本文以党参、油菜、水烛及罂粟等4种植物的蜂集花粉进行醇—水提取，经离子交换柱后得到游离氨基酸样品，提取后的花粉残渣以6ml/l盐酸封管水解制得结合氨基酸样品。

NAA, CPPU and EBR all induced parthenocarpic growth together with active cell division and enhanced transcripts of cell cycle-related genes.

奈乙酸，N-(2-氯-4-吡啶基)-N-苯基脲和表油菜素内酯都能诱导黄瓜单性结实，加快细胞分裂和提高细胞周期相关基因的表达。

Another three chromosome pairs showed their signals like pericentric heterochromatin block in the middle of which there was a constriction. The further studies showed there were no prominent FISH signals for this clone on the chromosomes of both O.

进一步研究表明，FISH分析中这一克隆在药用野生稻和玉米都没有明显信号；Southern分析中，药用野生稻和玉米的信号很弱，小麦、大麦、油菜和拟南芥中均未发现明显的信号。

In the bolting time and blooming time, B deficiency mainly influenced on the growth of the propagative organ of rapeseed ( Brassica Napus L.), the agronomic character was similar to the seedlings, and the B concentration range of the rapeseed varieties which responded to the B scarce was 0.005 mg/L to 0.25 mg/L.

苔期和花期，缺硼主要影响甘蓝型油菜繁殖器官的形成和发育，营养生长农艺性状的变化规律与苗期相似，品种间对缺硼反应差异最大的硼浓度范围为0.005 mg／L—0.25 mg／L。

The wall-broken Cole bee pollen lOOg is extracted by 1:10 of anhydrous ethanol , continuously stirred in darkness for two hours. And then by means of centrifuge, cleaning, vacuum concentration, adjusting pH value, anion exchange resin chromatography, propanone extraction,being blown to dry and freeze-dried, we use HPLC to detect the content of the GA derivative of the freeze-dried powder.

将破壁油菜蜂花粉100g，在避光条件下用无水乙醇(料液比1：10)连续搅拌浸提2小时，浸提液经离心、洗涤、真空浓缩、pH值调节、阴阳离子树脂交换、乙酸乙酯萃取、吹干再冻干后用HPLC法分析，得冻干样品中赤霉素衍生物的含量为51.29％。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
