To prevent unbalanced chromosome segregation, meiotic metaphase I - anaphase I transition is carefully regulated by delaying anaphase until all kinetochores are well oriented (anaphase checkpoint) in mammals and insects. In plants this has ...
Heterochromatin and sibling species of Simulium praelargum s.l. (Diptera: Simuliidae) [0.03%]
异染色质与Simulium praelargum复合种的近缘种伪种群结构(毛翅目:裂腿亚目)

Sachin Thapa et al.
Cytological descriptions are given for two sympatric sibling species, Simulium praelargum IIIL-st and Simulium praelargum IIIL-1.2, from Darjeeling, West Bengal, India. Sibling IIIL-1.2 differs from IIIL-st by a two step fixed included inve...
Two esterases from the genus Spodoptera degrade sex pheromones and plant volatiles [0.03%]
两种书夜蛾酯酶降解性信息素和植物挥发物
Peng He,Zhao-Qun Li,Cheng-Cheng Liu et al.
Peng He et al.
In moths, high temporal sensitivity in perception of sex pheromones and host plant volatiles suggests the existence of mechanisms acting to maintain antennal sensitivity. The antennal enzymes have been long hypothesized to play a central ro...
Comparative genome-scale analysis of niche-based stress-responsive genes in Lactobacillus helveticus strains [0.03%]

Next generation sequencing technologies with advanced bioinformatic tools present a unique opportunity to compare genomes from diverse niches. The identification of niche-specific stress-responsive genes can help in characterizing robust st...
Spontaneous germline excision of Tol1, a DNA-based transposable element naturally occurring in the medaka fish genome [0.03%]
鲤鱼基因组中天然存在的DNA转座子Tol1的生殖系自发切除
Kohei Watanabe,Hajime Koga,Kodai Nakamura et al.
Kohei Watanabe et al.
DNA-based transposable elements are ubiquitous constituents of eukaryotic genomes. Vertebrates are, however, exceptional in that most of their DNA-based elements appear to be inactivated. The Tol1 element of the medaka fish, Oryzias latipes...
Regulatory motifs identified from a maize developmental coexpression network [0.03%]

Gregory S Downs
Transcriptional control is an important determinant of plant development, and distinct modules of coordinated genes characterize the maize developmental transcriptome. Upstream regulatory sequences are often the primary factors that control...
Genetic structure of the four wild tomato species in the Solanum peruvianum s.l. species complex [0.03%]
泛秘鲁番茄复合体的四个野生番茄种的基因结构分析

Joanne A Labate et al.
The most diverse wild tomato species Solanum peruvianum sensu lato (s.l.) has been reclassified into four separate species: Solanum peruvianum sensu stricto (s.s.), Solanum corneliomuelleri, Solanum huaylasense, and Solanum arcanum. However...
Sequence analysis of single-copy genes in two wild olive subspecies: nucleotide diversity and potential use for testing admixture [0.03%]
两种野生橄榄亚种单拷贝基因的序列分析:核苷酸多态性及其检验杂交的可能性

Shivakumara Siddaramappa et al.
A large circular plasmid detected in Francisella novicida-like strain PA10-7858, designated pFNPA10, was sequenced completely and analyzed. This 41,013-bp plasmid showed no homology to any of the previously sequenced Francisella plasmids an...
An ancient satellite DNA has maintained repetitive units of the original structure in most species of the living fossil plant genus Zamia [0.03%]
一个古老的卫星DNA在活化石植物属茨藻中保持了原始结构的重复单元
Donata Cafasso,Gianni Chinali
Donata Cafasso
ZpS1 satellite DNA is specific to the genus Zamia and presents repetitive units organized as long arrays and also as very short arrays dispersed in the genome. We have characterized the structure of the ZpS1 repeats in 12 species representa...
