Diversity in the origins of sex chromosomes in anurans inferred from comparative mapping of sexual differentiation genes for three species of the Raninae and Xenopodinae [0.03%]
基于三类狭口蛙和 Xenopodinae 的性别分化基因比较图谱推断无尾目性染色体多样化的起源

Amphibians employ genetic sex determination systems with male and female heterogamety. The ancestral state of sex determination in amphibians has been suggested to be female heterogamety; however, the origins of the sex chromosomes and the ...
Refinement of macaque synteny arrangement with respect to the official rheMac2 macaque sequence assembly [0.03%]
绿猴官方rheMac2基因组序列图谱的完善工作

Roberta Roberto et al.
We have compared the synteny block organization of the official macaque genome sequence assembly (Jan. 2006; rheMac2) with an independent assembly that used a molecular cytogenetic approach. The mapping of four synteny segments, ranging in ...
Retroelements (LINEs and SINEs) in vole genomes: differential distribution in the constitutive heterochromatin [0.03%]
啮齿动物基因组中的转座元件(LINE和SINE)在构成异染色质中的不同分布规律

The chromosomal distribution of mobile genetic elements is scarcely known in Arvicolinae species, but could be of relevance to understand the origin and complex evolution of the sex chromosome heterochromatin. In this work we cloned two ret...
Meiotic behaviour of individual chromosomes of Festuca pratensis in tetraploid Lolium multiflorum [0.03%]

Intergeneric hybrids of fescues (Festuca spp.) and ryegrasses (Lolium spp.) are unique for the ability of their chromosomes to pair essentially freely in meiotic metaphase I (MI). At the same time, their chromosomes can be readily recognize...
Phylogenomic study of spiral-horned antelope by cross-species chromosome painting [0.03%]

Chromosomal homologies have been established between cattle (Bos taurus, 2n = 60) and eight species of spiral-horned antelope, Tribe Tragelaphini: Nyala (Tragelaphus angasii, 2n = 55male/56female), Lesser kudu (T. imberbis, 2n = 38male,fema...
FISH mapping and molecular organization of the major repetitive sequences of tomato [0.03%]
番茄中主要重复序列的鱼雷定位及其分子组成分析

Song-Bin Chang et al.
This paper presents a bird's-eye view of the major repeats and chromatin types of tomato. Using fluorescence in-situ hybridization (FISH) with Cot-1, Cot-10 and Cot-100 DNA as probes we mapped repetitive sequences of different complexity on...
