The Homoeologous Regions on Long Arms of Group 3 Chromosomes in Wheat and Barley Harbour Major Crown Rot Resistance Loci
Fusarium diseases genome mapping germplasm screening quantitative trait loci
2014/2/25
Crown rot (CR), caused by various Fusarium species, has become an important cereal disease worldwide and growing resistant varieties is an essential strategy to reduce the $A80 mil annual loss from CR...

The aim of the study was to select wheat-Aegilops biuncialis addition lines carrying Aegilops biuncialis chromosomes differing from those which were introgressed into the wheat-Ae. biuncialis addition...
家猪减数分裂粗线期二价体与有丝分裂中期染色体的比较研究Comparative Studies on Meiosis Pachytene Bivalents and MitosisCMetaphase Chromosomes of Pig (Sus scrofa domestica)
家猪 二价体 有丝分裂染色体 染色粒结构带 G-带
2008/1/30
摘要以性成熟公猪睾丸和外周血为材料，采用长低渗、高氯仿卡诺固定液固定和外周血细胞培养制备减数分裂粗线期二价体和有丝分裂中期染色体，通过对二价体和有丝分裂中期染色体分裂指数和长度的比较研究，发现二价体的分裂指数和长度分别是有丝分裂中期染色体的5倍和3.42倍(1.87～5.98)；同时以12号染色体为例, 比较了二价体上的染色粒结构带与有丝分裂中期染色体G-带，表明染色粒结构带比中期染色体G-带带纹...
