Whole genome re-sequencing reveals adaptation prior to the divergence of buffalo subspecies por Rafiepour, M., Ebrahimie, E., Vahidi, M.F., Salekdeh, G.H., Niazi, A., Dadpasand, M., Liang, Dong, Si, Jingfang, Ding, Xiangdong, Han Jianlin, Zhang, Yi, Qanbari, S.

“…Further validation using resequencing data from other five bovine species as well as the Axiom Buffalo Genotyping Array 90K data of river and swamp buffaloes indicated that these fixation signals persisted across river and swamp buffaloes and extended to taurine cattle, implying an ancient evolutionary event occurred before the speciation of buffalo and taurine cattle. These results contributed to our understanding of major genetic switches that took place during the evolution of modern buffaloes.…”

Haplotype-based phylogenetic analysis and population genomics uncover the origin and domestication of sweetpotato por Yan, M., Li, M., Wang, Y., Wang, X., Moeinzadeh, M., Quispe-Huamanquispe, D.G., Fan, W., Fang, Y., Nie, H., Wang, Z., Tanaka, A., Heider, B., Kreuze, Jan F., Gheysen, G., Wang, H., Vingron, M., Bock, R., Yang, J.M.

“…Our analyses revealed that genes involved in storage root formation, maintenance of genome stability, biotic resistance, sugar transport, and potassium uptake were selected during the speciation and domestication of sweetpotato. This study sheds light on the evolution of sweetpotato and paves the way for improvement of this crop.…”

Evolutionary dynamics of an ancient retrotransposon family provides insights into evolution of genome size in the genus Oryza por Ammiraju, Jetty S. S., Zuccolo, Andrea, Yu, Yeisoo, Song, Xiang, Piegu, Benoit, Chevalier, Frederic, Walling, Jason G., Ma, Jianxin, Talag, Jayson, Brar, Darshan S., SanMiguel, Phillip J., Jiang, Ning, Jackson, Scott A., Panaud, Olivier, Wing, Rod A.

“…In particular, we provide evidence that the basal GG genome ofOryza(O. granulata) has expanded by nearly 25% by a burst of theRWGlineageGran3subsequent to speciation. Finally we describe the recent evolutionary origin ofDasheng, a large retrotransposon derivative of theRWGfamily, specifically found in the A, B and C genome lineages ofOryza.…”
