, a representative tall aromatic tree of the Magnoliaceae family, is a medicinal plant that is widely used in diverse industries from medicine to cosmetics. We report a chromosome-scale draft genome of , in which ∼99.66% of the sequences were anchored onto 19 chromosomes with the scaffold N50 of 76.62 Mb. We found that a high proportion of repetitive sequences was a common feature of three Magnoliaceae with known genomic data. Magnoliids were a sister clade to eudicots-monocots, which provided more support for understanding the phylogenetic position among angiosperms. An ancient duplication event occurred in the genome of and was shared with Lauraceae. Based on RNA-seq analysis, we identified several key enzyme-coding gene families associated with the biosynthesis of lignans in the genome. The construction of the genome sequence will serve as a reference for further studies of as well as other Magnoliaceae.

Since the publication of its draft genome in 2007, the genome has drawn attention for several reasons, including its unusually large size, massive expansion of gene families, and high repeat content. The fragmented nature of the draft assembly made it challenging to obtain accurate metrics of features, such as spliceosomal introns.

The yellow fever mosquito () is an organism of high medical importance because it is the primary vector for diseases such as yellow fever, Zika, dengue, and chikungunya. Its medical importance has made it a subject of numerous efforts to understand their biology. One such effort, was the development of a high-quality reference genome (AaegL5).

Goosegrass, belonging to the genus Eleusine within the Chloridoideae subfamily, is often one of the problematic weeds with strong invasiveness, competing with crops for essential survival resources. Although a chromosome-level genome assembly of E. indica from China was published last year, the present research focuses on a population of E.

Siganus guttatus and Siganus oramin are two major species that are naturally distributed along the Eastern Pacific coast and possess considerable ecological and economic value. Here, we present the construction and comparative analysis of the chromosome-level genomes of these two Siganus species. Employing a hybrid assembly strategy, we partitioned and independently assembled the PacBio, Illumina and Hi-C reads of S.
