Tea is the world's oldest and most popular caffeine-containing beverage with immense
economic, medicinal, and cultural importance. Here, we present the first high-quality nucleotide …

Background Camellia is an economically and phylogenetically important genus in the family
Theaceae. Owing to numerous hybridization and polyploidization, it is taxonomically and …

Background Chloroplast genomes supply valuable genetic information for evolutionary and
functional studies in plants. The past five years have witnessed a dramatic increase in the …

Comparative genomic analyses among closely related species can greatly enhance our
understanding of plant gene and genome evolution. We report de novo-assembled AA-genome …

Polyploidy, or whole-genome duplication (WGD), serves as a key innovation in plant evolution
and is an important genomic feature for all eukaryotes. Neopolyploids have to overcome …

The tea tree Camellia sinensis, a member of the genus Camellia in the Theaceae family,
includes two major cultivated varieties, C. sinensis var. assamica (CSA; Assam type) and C. …

The ultimate goal of genome assembly is a high-accuracy gapless genome. Here, we report
a new assembly pipeline that is used to produce a gapless genome for the indica rice …

The origins of the Asian cultivated rice Oryza sativa from its wild ancestor O. rufipogon have
been debated for decades. The question mainly concerns whether it originated …

The gene duplication rate in the yeast genome is estimated without assuming the molecular
clock model to be ∼0.01 to 0.06 per gene per billion years; this rate is two orders of …

The rubber tree, Hevea brasiliensis, produces natural rubber that serves as an essential
industrial raw material. Here, we present a high-quality reference genome for a rubber tree …
