ObCYC1与模式植物金鱼草Antirrhinum majus中的CYC基因类似，集中在花冠背部区域表达，这与它们拥有保守的功能区TCP和R相一致。

Among those hydrogenbonding residues, Tyr119, His227, Asn392 and Leu451 could form hydrogen bond with the benzofuran inhibitots and Tyrl07, Asn175, Thr211 and Asp412 were newly discovered hydrogen-bonding residues, which were highly conserved residues across the NMT family and would play an important role in the design of NMT inhibitots with novel chemical scaffold.

CaNMT活性位点发现有两个氧键作用区域，其中Tyrll9，His227，Asn392和Leu451是与已有抑制剂的氢键结合位点，Tyr107，Asn175，Thr211和Asp412是新发现的氢键结合位点，而且在NMT家族中高度稳定，它们对设计新结构类型的CaNMT抑制剂具有重要作用。

Exception: biogenous materials which have been conserved in a special environment moor, glacial ice, volcanic sediments

除此之外：微生物一直生存在特殊的环境中（沼泽、冰川、火山沉积物）。在厌氧环境中，有机物的降解受到抑制或速度缓慢

Xanthomonas campestris pv. campestris is the causal agent of black rot disease of crucifers worldwide. In both plant and mammalian Gram-negative pathogenic bacteria, type III secretion systems, encoded by hrp cluster, play a crucial role in interactions with the host. The proteins assembled TTSS were highly conserved.

TheMADS box locates just at the 5'end of most of genes and is highly conserved.According to these,a primer was designed and the effort to isolate new membersof MADS box gene family in rice genome by RT-PCR was made.

绝大多数已克隆到的这类基因的MADS-box恰好位于5'端，而且非常保守，因此，我们根据MADS box基因的保守区设计了一个特异的引物，试图通过RT-PCR分离出水稻花中MADS box基因家族的新成员。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
