Sea slugs (Gastropoda: Opisthobranchia) are characterized by extensive morphological homoplasy. In particular, reduced or absent shells are predominant throughout the group. This trend towards shell loss has resulted in a poor fossil record...
Genomic scans detect signatures of selection along a salinity gradient in populations of the intertidal seaweed Fucus serratus on a 12 km scale [0.03%]
基因组扫描在12公里尺度上检测到了沿盐度梯度变化的潮间带褐藻Fucus serratus种群选择信号

Detecting natural selection in wild populations is a central challenge in evolutionary biology and genomic scans are an important means of detecting allele frequencies that deviate from neutral expectations among marker loci. We used nine a...
Evolution and comparative genomics of subcellular specializations: EST sequencing of Torpedo electric organ [0.03%]

Uncharacterized open reading frames (ORFs) in human genomic sequence often show a high degree of evolutionary conservation, yet have little or no tissue EST or protein data suggestive of protein product function. The encoded proteins may ha...
Cytogenetic analysis in Polypterus ornatipinnis (Actinopterygii, Cladistia, Polypteridae) and 5S rDNA [0.03%]

The identification of inteins in viral genomes is becoming increasingly common. Inteins are selfish DNA elements found within coding regions of host proteins. Following translation, they catalyse their own excision and the formation of a pe...
Genomic analysis of Vreelandella sp. F11 reveals its role in alginate utilization [0.03%]
基因组分析揭示Vreelandellasp.F11在利用藻酸盐中的作用
Alginate, mainly produced by brown algae, is an important polysaccharide that supports the growth of marine bacteria. Vreelandella sp. F11 is a Gram-negative and aerobic marine bacterium, which was isolated from the brown algae sample colle...
