In this study, a novel 28-bp insertion-deletion (indel) polymorphism (AJ298878:g.47836-47853insCCTCAGACACTGAGTCTCCCCAACAGCA) was found in goat prion protein (PRNP) gene in 2373 goats from 13 Chinese native breeds. The frequencies of allele ...

Island radiation constitutes a playground for species diversification, which has long fascinated researchers and still does today. Because only a small subset of taxa within the pool of island colonizers is concerned by this process, the qu...
Validation of microsatellite markers for cytotype discrimination in the model grass Brachypodium distachyon [0.03%]
模式草本植物二花苔草微卫星标记的验证以区分细胞类型

Patricia Giraldo et al.
Brachypodium distachyon (L.) P. Beauv. (2n = 2x = 10) is a small annual grass species where the existence of three different cytotypes (10, 20, and 30 chromosomes) has long been regarded as a case of autopolyploid series with x = 5. However...
Crossing over does occur in males of Drosophila ananassae from natural populations [0.03%]
来自自然界丛梗果蝇(Drosophila ananassae)雄性的确存在交叉互换现象

Beatriz Goñi et al.
Spontaneous crossing over in males of Drosophila ananassae has been well demonstrated using F(1) individuals from crosses between marker stocks and wild type strains. However, the question of its occurrence in males from natural populations...
Variations and classification of toxic epitopes related to celiac disease among α-gliadin genes from four Aegilops genomes [0.03%]
四个AY族长穗偃麦草基因组间醇溶蛋白毒性表位的变异与分类

Jie Li et al.
The α-gliadins are associated with human celiac disease. A total of 23 noninterrupted full open reading frame α-gliadin genes and 19 pseudogenes were cloned and sequenced from C, M, N, and U genomes of four diploid Aegilops species. Seque...
Mapping of the css (chloroplast splicing suppressor) gene(s) to a recombinationally suppressed region of chromosome III in Chlamydomonas reinhardtii [0.03%]

In previous work, three suppressors of defective group I introns (7151, 71N1, 7120) were isolated from a mutant of Chlamydomonas reinhardtii that had a splicing-deficient chloroplast large subunit (LSU) rRNA intron. Genetic analysis indicat...
Positional cloning of a gene responsible for the cts mutation of the silkworm, Bombyx mori [0.03%]

Katsuhiko Ito et al.
The larval head cuticle and anal plates of the silkworm mutant cheek and tail spot (cts) have chocolate-colored spots, unlike the entirely white appearance of the wild-type (WT) strain. We report the identification and characterization of t...
Association mapping of height and maturity across five environments using the sorghum mini core collection [0.03%]
利用高粱核心种质在五个环境中的株高和熟期的连锁不平衡分析

Hari D Upadhyaya et al.
Sorghum is a potential energy crop thanks to its high biomass productivity and low input. Biomass yield in sorghum is defined by height and maturity. To develop molecular breeding tools for genetic improvement of these two traits, we have i...
Increasing cotton genome coverage with polymorphic SSRs as revealed by SSCP [0.03%]
基于SSCP的多态性SSR标记在提高棉基因组覆盖率方面的研究
Ximei Li,Daojun Yuan,Hantao Wang et al.
Ximei Li et al.
Simple sequence repeat (SSR) markers are widely used in plant genetics and breeding. However, there are many SSR markers that do not reveal polymorphism in cotton. Traditional SSR genotyping methods only provide information on product sizes...
Integrated cytogenetic, ecological, and DNA barcode study reveals cryptic diversity in Simulium (Gomphostilbia) angulistylum (Diptera: Simuliidae) [0.03%]
染色体、生态和DNA条形码综合研究揭示Simulium (Gomphostilbia) angulistylum (双翅目：裂蚊科)的隐存多样性
