Conyza sumatrensis and Conyza bonariensis are two important hexaploid weed species that impact crop production systems across the globe. Here, we report reference genome assemblies for both species. The sequenced accession of C. sumatrensis...
Genome-wide temporal gene expression reveals a post-reproductive shift in the nematode C. briggsae [0.03%]
秀丽隐杆线虫C.briggsae全基因组范围内的表达谱揭示了其生殖后时期的基因变化规律

The nematodes Caenorhabditis briggsae and its well-known cousin Caenorhabditis elegans offer many features for comparative investigations of genetic pathways that affect physiological processes. Reproduction is one such process that directl...
Parameterizing Pantherinae: de novo mutation rate estimates from Panthera and Neofelis pedigrees [0.03%]
从豹亚科的系谱估计新的突变率：来自豹属和云豹属的数据从头开始参数化 Panthers

Estimates of de novo mutation rates are essential for phylogenetic and demographic analyses, but their inference has previously been impeded by high error rates in sequence data and uncertainty in the fossil record. Here, we directly estima...
Repeated evolution of transcript dosage compensation of independently formed nematode neo-X chromosomes [0.03%]
独立形成的线虫新X染色体的转录剂量补偿的重复进化

Ohno proposed that, during the origin of X/Y sex chromosomes from a pair of autosomes, X-linked genes must double their per-allele expressions to compensate for the degeneration of their Y homologs. Whether Ohno's hypothesis holds in the ne...
Analyses of Transposable Elements in Arbuscular Mycorrhizal Fungi Support Evolutionary Parallels With Filamentous Plant Pathogens [0.03%]
丛枝菌根真菌中可转座元件的分析支持其与植物病原真菌进化上的平行关系

Jordana I N Oliveira et al.
Transposable elements are repetitive DNA sequences that excise or create copies that are inserted elsewhere in the genome. Their expansion shapes genome variability and evolution by impacting gene expression and rearrangement rates. Arbuscu...
Transcriptomic temperature stress responses show differentiation between biomes for diverse plants [0.03%]
转录组温度应力响应显示出不同生物群落的植物分化

Samuel C Andrew et al.
Plants are foundational to terrestrial ecosystems and because they are sessile, are particularly reliant on physiological plasticity to respond to weather extremes. However, variation in conserved transcriptomic responses to temperature ext...

Contemporary patterns of genetic variation reflect the cumulative history of a population. Population splitting, migration, and changes in population size leave genomic signals that enable their characterization. Existing methods aimed at r...

In prokaryotes, functionally linked genes are typically clustered into operons, which are transcribed into a single mRNA, providing for the coregulation of the production of the respective proteins, whereas eukaryotes generally lack operons...
Genomic Insights into Fertilization: Tracing PLCZ1 Orthologs Across Amphibian Lineages [0.03%]
基因组对受精的见解：追踪两栖类动物系中的PLCZ1同源物
Rachel E Bainbridge,Joel C Rosenbaum,Paushaly Sau et al.
Rachel E Bainbridge et al.
Fertilization triggers a cascade of events, including a rise in egg cytosolic calcium that marks the onset of embryonic development. In mammals and birds, this critical process is mediated by the sperm-derived phospholipase C zeta (PLCζ), ...
