Wanting Ge et al.
Catalpa huangxin, a distinctive taxon within the genus Catalpa in China, is valued for its ornamental beauty and durable yellow heartwood. However, its wild populations are declining due to climate change and human activities, posing urgent...
Tissue-specific differences of gene expression variance in mutation accumulation lines of mice [0.03%]
小鼠突变积累系的组织特异性基因表达变异度差异分析

Eugenio López-Cortegano et al.
New mutations are the source of all genetic variation, including variation affecting quantitative phenotypes. Here, in order to evaluate the impact of mutations on the integrated function of entire tissues, we estimated the mutational varia...
Routine mitochondrial recombination drives rapid concerted evolution of duplicated control regions in a wild fish [0.03%]
线粒体重组驱动野生鱼类重复控制区的迅速平行演化
Handung Nuryadi,V K Anoop,Ryo Kakioka et al.
Handung Nuryadi et al.
Duplications and concerted evolution of control regions (CRs) in animal mitogenomes have been reported across diverse taxa, yet the tempo and mechanism of gene conversion remain poorly understood. Here, we assembled the complete mitochondri...
Copy number variation and evolution of MHC class I and II genes in lovebirds (Agapornis, Psittaculidae, Psittaciformes) [0.03%]

Gene duplication and loss play an important role in the evolution of the major histocompatibility complex (MHC). Variations in copy number and sequence diversity of MHC genes can have significant fitness consequences. Here, we characterized...
Dwarfism in Pinus taeda originates from independent somatic mutations co-localized in a shared genomic region [0.03%]
火炬松矮化性状起源于共享基因组区域的体细胞独立突变

Pinar Guner et al.
Somatic mutations in long-lived conifers are rarely characterized yet offer a unique window into the spontaneous genetic forces that shape variation in plants. In Pinus taeda, dwarf phenotypes originate from abnormal branches, colloquially ...
Genomic evidence of divergence-with-gene-flow in the pink shrimp Farfantepenaeus brasiliensis [0.03%]
粉虾Farfantepenaeus brasiliensis分化伴随着基因流动的基因组证据

A Rus Hoelzel et al.
Segregating alleles in natural populations can be driven to fixation or loss by genetic drift or directional selection, or may be maintained in a polymorphic state by balancing selection. Balancing selection in a panmictic population is the...
Rapid evolution of a large structural polymorphism during a bacterial epidemic [0.03%]
细菌在传染病大流行期间大型结构多态性快速演变
Eric Dexter,Pascal Angst,Peter D Fields et al.
Eric Dexter et al.
The field of population genetics is primarily focused on simple genetic variants such as single nucleotide polymorphisms (SNPs), small insertions or deletions (INDELs), and copy-number variants (CNVs). However, large-scale genomic variants ...
Genomic insights into population structure and predictive breeding for climate-resilient coffee [0.03%]
基因组学视角下的群体结构与预测育种助力咖啡抗逆驯化

N&#x;Da Desire Pokou et al.
Climate change poses a growing threat to global coffee production, particularly for Coffea arabica, the most widely cultivated species. Coffea canephora (Robusta), with greater tolerance to heat and environmental stress, represents a critic...
mariner elements as a model for analyzing the stress response and somatic mobilization activity of transposable elements [0.03%]
海洋菌要素作为分析应力反应和游离移动元件的体细胞动员活动的模型
