We elucidate grapevine evolution and domestication histories with 3525 cultivated and wild accessions worldwide. In the Pleistocene, harsh climate drove the separation of wild grape ecotypes caused by continuous habitat fragmentation. Then, domestication occurred concurrently about 11,000 years ago in Western Asia and the Caucasus to yield table an...

In many flowering plants, male and female reproductive organs mature at different times to avoid self-pollination, a phenomenon termed dichogamy. Most dichogamous species are either protandrous (male function first) or protogynous (female function first), making this strategy difficult to be studied. However, in the ginger Alpinia mutica , protandr...

The genus Camellia contains three types of domesticates that meet various needs of ancient humans: the ornamental C. japonica, the edible oil-producing C. oleifera, and the beverage-purposed tea plant C. sinensis. The genomic drivers of the functional diversification of Camellia domesticates remain unknown. Here, we present the genomic variations o...

Lamiales, comprising over 23,755 species across 24 families, stands as a highly diverse and prolific plant group, playing a significant role in the cultivation of horticultural, ornamental, and medicinal plant varieties. Whole-genome duplication (WGD) and its subsequent post-polyploid diploidization (PPD) process represent the most drastic type of...

Gene duplication is assumed to serve as the key in evolution of metabolite biosynthesis in plants. Freed from the functional burdens, duplicated genes could mutate toward novelties until fixed due to the selective fitness. Yet the extent to which this mechanism has driven the diversification of metabolite biosynthesis remains to be tested. Here we...

The Muscovy duck (Cairina moschata) is an economically important poultry species, which is susceptible to fatty liver. Thus, the Muscovy duck may serve as an excellent candidate animal model of non-alcoholic fatty liver disease. However, the mechanisms underlying fatty liver development in this species are poorly understood. In this study, we repor...

The diversity of Central Asians has been shaped by multiple migrations and cultural diffusion.
