查询词典 chromosomal

The effect of phosphoric amide herbicide amiprophose-methyl, which was used wildly in agriculture, on chromosome structure and protein composition of root meristems of wheat were studied by exposure to concentrations of 1-4 μmol/L. The results indicated that, as the concentration of APM increased the frequency of chromosomal structure variation increased.

混合粒子场与γ射线诱发的微核畸变率和染色体畸变率均存在明显的剂量效应，但混合粒子场的损伤效应明显高于γ射线。

The results showed that the irradiation of mixed high-energy particle field inhibited mitoses and produced various chromosomal aberrations such as micronucleus, chromosome bridges, circular chromosomes and dissociative chromosomes in root tip cells of wheat with significant dose-effects.

混合粒子场与γ射线诱发的微核畸变率和染色体畸变率均存在明显的剂量效应，但混合粒子场的损伤效应明显高于γ射线。

The genomic DNA of Thinopyron intermedium labelled with biotin-16-dUTP was hybridized with the chromosomal DNA of Wheat-Th. intermedium addition Line Z,(2n = 44), which had a good resistance to barley yellow dwarf vims.

以生物素（Biotin－16－dUTP）标记中间偃麦草基因组 DNA为探针，与抗黄矮病小麦－中间偃麦草染色体异附加系Z6进行原位杂交，鉴定出附加的1对中间偃麦草染色体。

Chromosomal abnormalities, single mutant genes, and maternal diabetes mellitus or ingestion of teratogens, such as antiepileptic drugs, are implicated in about 10% of the cases.

孕中期诊断无脑畸形基于颅顶和大脑半球缺乏，然而面骨、脑干和部分枕骨、中脑通常存在。大约50%的病例合并脊柱异常，早孕期，可在11周后做出诊断，因为此时，颅骨开始骨化。
