查询词典 chromosome

Thinopyrum intermedium,one of the relative species of common wheat,is a kind of dominant wheat germplasm resource for the resistance to stripe rust in wheat genetic improvement. With using Chinese spring phlb as recurrent parents and awnless Zhong 4(a partial chromosome of Thinopyrum intermedium)as donor parents,that is backcross selection,the offspring BC_2F_(7～9)were acquired.Cytology check and genome in situ hybridization, were used for the translocation lines and substitution lines detection.

本研究采用常规杂交并辅抗性鉴定等方法，以中国春phlb突变体为轮回亲本，利用无芒中4，转育中间偃麦草的抗条锈性，并通过细胞学和DNA原位杂交检测，鉴定和筛选普通小麦—中间偃麦草的抗条锈病异代换系或易位系。

Five pairs of 45S rDNA loci and two pairs of 5S rDNA signals were detected on chromosomes of Cucurbita moschata Duch. Luffa cylindrical Roem. contained five pairs of 45S rDNA loci and one pair of 5S rDNA loci. In Benincasa hispida Cogn., two pairs of 45S rDNA sites and one pair of 5S rDNA site were detected. In this species, 5S rDNA and one pair of the 45S loci were collocated closely in chromosome 7S. 45S rDNA chromosomal distribution patterns were highly conserved among the three species, althoufh their number varied markedly. The 5S rDNA sites on chromosomes among the three species were highly polymorphic.

南瓜有5对45S rDNA位点， 2对5S rDNA位点；丝瓜具有5对45S rDNA位点， 1对5S rDNA位点；冬瓜具有2对45S rDNA位点， 1对5S rDNA位点， 5S rDNA位点与其中一对45S rDNA位点都位于7号染色体短臂上，并在物理位置上紧密相邻。45S rDNA在这3种作物染色体上数目变化较大，但在染色体上都倾向分布在短臂末端，其分布模式较为一致。5S rDNA在这3种作物染色体上数目相对保守，但在染色体上分布的位置变化较大。
