The chromosome composition of Yuan Zhong 2, a common wheat-Ag.intermedium partial amphiploid (2n=54), was analyzed with the genomic in situ hybridization,in which the biotinylated total DNA of Ag.intermedium as the probe and the total DNA of common wheat cv.Chinese Spring as blocking DNA were used to hybridize with the chromosome DNA of Yuan Zhong 2 at mitotic metaphase in root tip cells.

为分析普通小麦-天兰冰草部分双二倍体-远中2号(2n=54)的染色体构成，用生物素(biotin-16-dUTP)标记天兰冰草染色体组DNA作为探针，以普通小麦品种中国春染色体组DNA为封闭DNA，与远中2号的有丝分裂中期染色体DNA进行了分子原位杂交。

In the post-genomic era, protein function annotation is one of the most important problems.

蛋白质功能预测是后基因组时代研究的重要问题之一。

Study of ApoD has been largely focused on its expression and physiological function, and information regarding its genomic orgnization and regulatory elements is extremely limited.

目前，对ApoD的研究主要集中在基因表达、组织分布和生理功能上，对其包括调控区在内的基因组结构分析相对较少，而这对于深入阐明ApoD功能及其基因表达调控具有重要意义。

Objective To explore a new method to isolate genomic DNA from human blood clot.

目的 建立一种新的从人血凝块中提取基因组DNA的方法。

The genomic organization differences at both gene junctions provide new evidence of extremely divergence between Heterotremata and Thoracotremata in brachyuran crabs.

两个基因连接部的基因组成差异为短尾类内部异孔类与胸孔类之间的歧异提供了新的证据。

Based on the understanding of physiological pathway for broodiness, three genes related to broodiness including PRL, PRL receptor, and pituitary-specific transcription factor (POU1F1)-encoding genes were selected as candidates to screen the genomic variation by means of PCR-SSCP protocol and analyze the association with chicken broodiness and other target traits.

禽类血浆PRL水平上升与就巢行为的起始和维持具有密切的相关性，本研究采用候选基因的策略，通过分析就巢行为发生的生理机制，选择与就巢性状密切关联的PRL、PRL受体和PRL转录调控因子——垂体特异转录因子(pituitary-specific transcription factor，POUlF1)基因，采用PCR-SSCP分析检测基因变异，并分析基因变异与就巢性和其它目标性状的相关性。

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.
