Leeches are well known for blood-feeding habits and widely used medicinal purposes as they secrete various antithrombotic substances. However, some leeches exhibit non-hematophagous their significance use is controversial. Here we provide the chromosome-level genomes of two leeches, Whitmania acranulata laevis, and, in combination with previous results from pigra, compared these an emphasis on biomolecules. All three species had same chromosome number 11. The genome size, repeat site percentage, protein-coding genes W. laevis (173.87 Mb, 28.28%, 23,818) were similar to those pigra (169.37 27.02%, 24,156), whereas values (181.72 29.55%, 27,069) higher than other leeches. was a monophyletic clade paraphyletic relationship pigra.

The deciduous tree Idesia polycarpa can provide premium edible oil with high polyunsaturated fatty acid contents. Here, we generate its high-quality reference genome, which is ∼1.21 Gb, comprising 21 pseudochromosomes and 42,086 protein-coding genes. Phylogenetic genomic synteny analyses show that it diverged Populus trichocarpa about 16.28 million years ago. Notably, most biosynthesis genes are not only increased in number genome but also highly expressed the fruits. Moreover, identify, through genome-wide association analysis RNA sequencing, I. SUGAR TRANSPORTER 5 (IpSTP5) gene as a positive regulator of accumulation Silencing IpSTP5 by virus-induced silencing causes significant reduction content fruits, suggesting has potential to be used molecular marker breed high-oil-content cultivars. Our results collectively lay foundation for breeding elite cultivars polycarpa.

Biological invasions pose a significant threat to ecosystems, disrupting local biodiversity and ecosystem functions. The genomic underpinnings of invasiveness, however, are still largely unknown, making it difficult predict manage invasive species effectively. common reed (Phragmites australis) is dominant grass in wetland ecosystems has become particularly when transferred from Europe North America. Here, we present high-quality gap-free, telomere-to-telomere genome assembly Phragmites australis consisting 24 pseudochromosomes B chromosome. Fully phased subgenomes demonstrated considerable subgenome dominance revealed the divergence diploid progenitors approximately 30.9 million years ago. Comparative genomics using chromosome-level scaffolds for three other lineages previously published draft an lineage that gene family expansions form tandem duplications may have contributed invasiveness lineage. This study sheds light on evolution Arundinoideae grasses suggests genetic drivers, such as duplications, underly processes biological invasion plants. These findings provide crucial step toward understanding managing basis plant species.

Lycophytes and ferns represent one of the earliest-diverging lineages vascular plants, with Lycopodiaceae family constituting basal clade among lycophytes. In this research, we successfully assembled annotated complete Lycopodium japonicum Thunb.

Prunus subgenus Cerasus (Mill) A. Gray, commonly known as cherries and cherry blossoms, possesses significant edible ornamental value. However, the mitochondrial genomes (mitogenomes) of species remain largely unexplored. Here, we successfully assembled mitogenomes five ( P. campanulata , fruticosa mahaleb pseudocerasus sp eciosa ), revealing common circular structures. The exhibited sizes ranging from 383,398 bp to 447,498 bp, with GC content varying between 45.54% 45.76%. A total 62 69 genes were annotated, variability in copy number protein-coding (PCGs) tRNA genes. Mitogenome collinearity analysis indicated genomic rearrangements across species, driven by repetitive sequences, particularly dispersed repeats. Additionally, displayed highly conserved codon usage RNA editing patterns, highlighting evolutionary conservation PCGs. Phylogenetic analyses confirmed monophyly subg. although notable phylogenetic incongruences observed plastid datasets. These results provide resources for forthcoming studies on evolution molecular breeding mitogenomes, enhancing overall comprehension mitogenome structure within .

Ilex rotunda Thunb. stands as a representative tree species in subtropical evergreen broad-leaved forests, widely distributed across southeast Asia. This holds significant value forestry due to its ecological resilience and adaptability. Although researchers have conducted in-depth research on the plastid genome (plastome) of I. rotunda, mitochondrial (mitogenome) this has remained undocumented.
