Stable isotopic analysis on ancient human bones in Jiahu site

Science China Earth Sciences 2007年第4期50卷 563-570页

作者： S.H.AMBROSE lab of Biogeochemistry Department of Anthropology University of Illinios Urbana-Champaign Urbla 61801 USA

Palaeodietary analysis is one of important topics in bioarchaeology field and has been paid great at- tention to by Chinese archaeometrists recently. Ancient human bones in Jiahu Site were analyzed by means of stable isotopes of C, N and O. 13 human bones were excluded from 28 bones for dietary re- construction due to their unusual collagen contents, C and N contents, and C/N atomic ratios espe- cially. δ 13C (-20.37±0.53‰) in collagen of remaining samples showed that C3 food were consumed mainly, which is consistent of the archaeological findings that rice was the staple in Jiahu. According to the difference of δ 15N and δ 13C values in bone collagen, the samples can be classified into four clusters. The changes of δ 15N values in bone collagen and δ 13C values in hydroxylapatite through whole cultural phases indicated the transition from hunting to gathering and fishing to rice agriculture and animal domestication ultimately. Meanwhile, the δ 18O change in hydroxylapatite showed that pa- laeoclimate was relatively constant during Jiahu culture.

Largemouth bass(Micropterus salmoides) is an economically important fish species in North America, Europe, and China. Various genetic improvement programs and domestication processes have modified its genome sequence through selective pressure, leaving nucleotide signals that can be detected at the genomic level. In this study,we sequenced 149 largemouth bass fish, including protospecies(imported from the US) and improved breeds(four domestic breeding populations from China). We detected genomic regions harboring certain genes associated with improved traits, which may be useful molecular markers for practical domestication, breeding, and selection. Subsequent analyses of genetic diversity and population structure revealed that the improved breeds have undergone more rigorous genetic changes. Through selective signal analysis, we identified hundreds of putative selective sweep regions in each largemouth bass line. Interestingly, we predicted 103 putative candidate genes potentially subjected to selection,including several associated with growth(psst1 and grb10), early development(klf9, sp4, and sp8), and immune traits(pkn2, sept2, bcl6, and ripk2). These candidate genes represent potential genomic landmarks that could be used to improve important traits of biological and commercial interest. In summary, this study provides a genome-wide map of genetic variations and selection footprints in largemouth bass, which may benefit genetic studies and accelerate genetic improvement of this economically important fish.

The article ‘Structural variation during dog domestication:insights from grey wolf and dhole genomes’ by Wang et al. presented the first and comprehensive study of the evolutionary dynamics of structural variation of dogs based on three assembled Canine genomes [1].Structural variations (SVs) play a prominent role during the domestication of animals in phenotypic evolution, disease susceptibility and environmental adaptation. As the first animal to be domesticated, the dog is of great interest and significance to

Genomics Approaches to domestication Studies of Horticultural Crops

The majority of crops we eat today are derived from the domestication of their wild progenitors. Crop domestication satisfies the human need for food and nutrition. Characterization of the history and genetic basis of crop domestication is essential for us to conduct modern breeding practices. Genomics provide unprecedented opportunities for us to study domestication. In this review, the typical domestication syndromes of horticultural crops will be introduced. Using the tomato as a typical example, we will discuss how genetic and genomic data were used to decipher the origins, progenitors, and domestication processes of this crop. In the domestication exploration of the genetic basis especially,genome-scaled diversity scanning approaches have gained great popularity. Combining these approaches with QTL(Quantitative trait locus)-mapping, GWAS(Genome wide association study), metabolomics and homology-based searches as well as pan-genomics have demonstrated tremendous advantages and significantly contribute to our understanding of domestication. Genomics studies will accelerate domestication research and further breeding of crops.
