MicroRNAs (miRNAs) are pivotal regulators of gene expression, playing crucial roles in plant developmental processes and environmental responses. However, the function of miRNAs in influencing deciduous traits has been little explored. Here, we utilized sRNA-seq on two deciduous species, (Hand.

Landform and lithospheric development contribute to the assembly of mountain floras in China.

Although it is well documented that mountains tend to exhibit high biodiversity, how geological processes affect the assemblage of montane floras is a matter of ongoing research. Here, we explore landform-specific differences among montane floras based on a dataset comprising 17,576 angiosperm species representing 140 Chinese mountain floras, which we define as the collection of all angiosperm species growing on a specific mountain. Our results show that igneous bedrock (granitic and karst-granitic landforms) is correlated with higher species richness and phylogenetic overdispersion, while the opposite is true for sedimentary bedrock (karst, Danxia, and desert landforms), which is correlated with phylogenetic clustering.

 (Aspleniaceae), a distinct new fern species from northern Guangdong, China, based on morphological data and molecular phylogeny.

A new spleenwort species, , was found and described from Danxia landform region in Guangdong, China. The new species has close resemblance to Ching ex S.H.

PMAT: an efficient plant mitogenome assembly toolkit using low-coverage HiFi sequencing data.

Complete mitochondrial genomes (mitogenomes) of plants are valuable resources for nucleocytoplasmic interactions, plant evolution, and plant cytoplasmic male sterile line breeding. However, the complete assembly of plant mitogenomes is challenging due to frequent recombination events and horizontal gene transfers. Previous studies have adopted Illumina, PacBio, and Nanopore sequencing data to assemble plant mitogenomes, but the poor assembly completeness, low sequencing accuracy, and high cost limit the sampling capacity.

The first mitogenome of Lauraceae ().

•The first reported mitochondrial genome () of the Lauraceae family.•The mitogenome of retains almost all of the ancestral protein-coding genes and has the highest RNA editing number in angiosperms.•Both of the plastid and mitochondrial phylogenetic trees support the magnoliids as a sister group of monocots and eudicots.

Molecular, chromosomal, and morphological evidence reveals a new allotetraploid fern species of (Aspleniaceae) from southern Jiangxi, China.

, a new tetraploid fern species of the complex (Aspleniaceae) from Jiulianshan National Nature Reserve, southern Jiangxi, China is described and illustrated. We inferred the phylogenetic position of the new species based on sequences from seven plastid markers (, , , , , , and ) and one low-copy nuclear gene, . The plastid phylogeny supported a close relationship among the new species , , and , while the nuclear phylogeny differed in topology from the plastid tree.

A new spikemoss species, , is described and illustrated based on materials collected from Fujian Province, East China. The new species can be distinguished from Koidzumi and P. S.

 (Aspleniaceae), a new fern species from southeastern Xizang, China based on morphological and molecular evidence.

A new species of Aspleniaceae, sp. nov., is described from Medog County in southeastern Xizang, China.

The chromosome-level holly () genome reveals key enzymes in triterpenoid saponin biosynthesis and fruit color change.

The L. (hollies) genus of Aquifoliaceae shows high species diversity in tropical and subtropical regions of Asia and South America. Throughout the range of the genus, species have been widely used in beverage and medicine production and as ornamentals.

Molecular phylogenetic analyses based on the complete plastid genomes and nuclear sequences reveal (Thymelaeaceae) to be non-monophyletic as current circumscription.

The diverse members of the genus are prized for their fragrant flowers. Despite being promising ornamental plants in many countries, genetic information of is scarce. In this study, the plastomes of four species and one variety of were sequenced and analyzed.

Comparative analysis of complete Ilex (Aquifoliaceae) chloroplast genomes: insights into evolutionary dynamics and phylogenetic relationships.

Background: Ilex (Aquifoliaceae) are of great horticultural importance throughout the world for their foliage and decorative berries, yet a dearth of genetic information has hampered our understanding of phylogenetic relationships and evolutionary history. Here, we compare chloroplast genomes from across Ilex and estimate phylogenetic relationships.

Results: We sequenced the chloroplast genomes of seven Ilex species and compared them with 34 previously published Ilex plastomes.

When tropical and subtropical congeners met: Multiple ancient hybridization events within Eriobotrya in the Yunnan-Guizhou Plateau, a tropical-subtropical transition area in China.

Global climate changes during the Miocene may have created ample opportunities for hybridization between members of tropical and subtropical biomes at the boundary between these zones. Yet, very few studies have explored this possibility. The Yunnan-Guizhou Plateau (YGP) in Southwest China is a biodiversity hotspot for vascular plants, located in a transitional area between the floristic regions of tropical Southeast Asia and subtropical East Asia.
