The regulation of energy homeostasis is pivotal to survive periods of inadequate nutrition. A combination of intricate pathways and proteins are responsible for maximizing longevity during such conditions. The sirtuin deacetylase Sir2 is we...
Aneuploid progeny of the American oyster, Crassostrea virginica, produced by tetraploid × diploid crosses: another example of chromosome instability in polyploid oysters [0.03%]
美国牡蛎（Crassostrea virginica）四倍体与二倍体杂交产生的染色体数目异常的后代：多倍体牡蛎中染色体不稳定的另一例证

Joana Teixeira de Sousa et al.
The commercial production of triploids, and the creation of tetraploid broodstock to support it, has become an important technique in aquaculture of the eastern oyster, Crassostrea virginica. Tetraploids are produced by cytogenetic manipula...
Microsatellite landscape evolutionary dynamics across 450 million years of vertebrate genome evolution [0.03%]
微卫星在4.5亿年的脊椎动物基因组演化中的进化动力学变迁规律分析
Richard H Adams,Heath Blackmon,Jacobo Reyes-Velasco et al.
Richard H Adams et al.
The evolutionary dynamics of simple sequence repeats (SSRs or microsatellites) across the vertebrate tree of life remain largely undocumented and poorly understood. In this study, we analyzed patterns of genomic microsatellite abundance and...
Meiotic recombination is suppressed near the histone-defined border of euchromatin and heterochromatin on chromosome 2L of Drosophila melanogaster [0.03%]
果蝇2号染色体长臂上的组蛋白定义的常染色质和异染色质交界处附近的减数重组受到抑制
Alistair B Coulthard,Rhodri W Taylor-Kamall,Graham Hallson et al.
Alistair B Coulthard et al.
In Drosophila melanogaster, the borders between pericentric heterochromatin and euchromatin on the major chromosome arms have been defined in various ways, including chromatin-specific histone modifications, the binding patterns of heteroch...
Molecular cytogenetic identification of a wheat-rye 1R addition line with multiple spikelets and resistance to powdery mildew [0.03%]
具有多小穗和抗白粉病性状的1R染色体小麦/黑麦代换系的分子细胞遗传鉴定
Wujuan Yang,Changyou Wang,Chunhuan Chen et al.
Wujuan Yang et al.
Alien addition lines are important for transferring useful genes from alien species into common wheat. Rye is an important and valuable gene resource for improving wheat disease resistance, yield, and environment adaptation. A new wheat-rye...

Long non-coding RNAs (lncRNAs) are transcribed RNA molecules >200 nucleotides in length that do not encode proteins and serve as key regulators of diverse biological processes. Recently, thousands of long intergenic non-coding RNAs (lincRNA...
Genome scan for nonadditive heterotic trait loci reveals mainly underdominant effects in Saccharomyces cerevisiae [0.03%]
基因组扫描揭示出非加性杂种优势位点在酿酒酵母中主要表现为显隐性效应
Efrat Laiba,Ilana Glikaite,Yael Levy et al.
Efrat Laiba et al.
The overdominant model of heterosis explains the superior phenotype of hybrids by synergistic allelic interaction within heterozygous loci. To map such genetic variation in yeast, we used a population doubling time dataset of Saccharomyces ...
Characterization and abiotic stress-responsive expression analysis of SGT1 genes in Brassica oleracea [0.03%]
芸苔属蔊菜SGT1基因的鉴定及其非生物胁迫响应表达分析
Ashokraj Shanmugam,Senthil Kumar Thamilarasan,Jong-In Park et al.
Ashokraj Shanmugam et al.
SGT1 genes are involved in enhancing plant responses to various biotic and abiotic stresses. Brassica oleracea is known to contain two types of SGT1 genes, namely suppressor of G2 allele of SKP1 and suppressor of GCR2. In this study, throug...
Automatic detection of rate change in large data sets with an unsupervised approach: the case of influenza viruses [0.03%]
大数据集中自动检测流感病毒等病原体的速率变化
Kasandra Labonté,Stéphane Aris-Brosou
Kasandra Labonté
Influenza viruses evolve at such a high rate that vaccine recommendations need to be changed, but not quite on a regular basis. This observation suggests that the rate of evolution of these viruses is not constant through time, which begs t...
Characterization of wheat - Psathyrostachys huashanica small segment translocation line with enhanced kernels per spike and stripe rust resistance [0.03%]
具有增加小穗数和条锈病抗性的小麦-Psathyrostachys huashanica小片段易位系的鉴定
Hou-Yang Kang,Zhi-Juan Zhang,Li-Li Xu et al.
Hou-Yang Kang et al.
Psathyrostachys huashanica Keng (2n = 2x = 14, NsNs), a distant wild relative of common wheat, possesses rich potentially valuable traits, such as disease resistance and more spikelets and kernels per spike, that could be useful for wheat g...
