Diploid and tetraploid genomes of Acorus and the evolution of monocots.

Monocots are a major taxon within flowering plants, have unique morphological traits, and show an extraordinary diversity in lifestyle. To improve our understanding of monocot origin and evolution, we generate chromosome-level reference genomes of the diploid Acorus gramineus and the tetraploid Ac. calamus, the only two accepted species from the family Acoraceae, which form a sister lineage to all other monocots.

Genomes of leafy and leafless Platanthera orchids illuminate the evolution of mycoheterotrophy.

To improve our understanding of the origin and evolution of mycoheterotrophic plants, we here present the chromosome-scale genome assemblies of two sibling orchid species: partially mycoheterotrophic Platanthera zijinensis and holomycoheterotrophic Platanthera guangdongensis. Comparative analysis shows that mycoheterotrophy is associated with increased substitution rates and gene loss, and the deletion of most photoreceptor genes and auxin transporter genes might be linked to the unique phenotypes of fully mycoheterotrophic orchids. Conversely, trehalase genes that catalyse the conversion of trehalose into glucose have expanded in most sequenced orchids, in line with the fact that the germination of orchid non-endosperm seeds needs carbohydrates from fungi during the protocorm stage.

The Cymbidium genome reveals the evolution of unique morphological traits.

The marvelously diverse Orchidaceae constitutes the largest family of angiosperms. The genus Cymbidium in Orchidaceae is well known for its unique vegetation, floral morphology, and flower scent traits. Here, a chromosome-scale assembly of the genome of Cymbidium ensifolium (Jianlan) is presented.

The Euscaphis japonica genome and the evolution of malvids.

Malvids is one of the largest clades of rosids, includes 58 families and exhibits remarkable morphological and ecological diversity. Here, we report a high-quality chromosome-level genome assembly for Euscaphis japonica, an early-diverging species within malvids. Genome-based phylogenetic analysis suggests that the unstable phylogenetic position of E.

The complete chloroplast genome sequence of (Ericaceae).

is one of the representative plants of Ericaceae family, which was famous for entire translucent and 'ghostly' white. Also, unique lifestyle also attracts lots of researchers, which it obtains through fixed carbon from photosynthetic plants via a shared mycorrhizal network. In this study, the complete chloroplast (cp) genome of was assembled and annotated, its full-length is 26,913 bp.

Genome-Wide Identification of the Gene Family in Seven Species of Magnoliids and Expression Analysis in .

The gene family, specific to seed plants, encodes a class of transcription factors in the lamina maintenance and development of lateral organs. Magnoliids are sisters to the clade-containing eudicots and monocots, which have rapidly diversified among the common ancestors of these three lineages. However, prior to this study, information on the function of the genes in magnoliids was extremely limited to the third major clades and the early diverging lineage of Mesangiospermae.

The genome sheds light on the evolution of magnoliids.

Lauraceae includes the genus , and the family is linked to the evolution of magnoliids. We sequenced the genome of Nanmu. The assembled genome size was 989.

Complete chloroplast genome of (chloranthaceae).

The complete chloroplast genome of , an important traditional Chinese herbal medicine, was sequenced and characterized in this study. The genome size is 157,990 bp in length with 37.3% GC content.
