Molecular insights into floral scent biosynthesis in through transcriptomic and metabolomic analyses.

Michx., a member of the genus in Rosaceae, has large, pure white flowers with a pleasant floral scent, making it a valuable ornamental and aromatic plant. However, the composition and dynamic changes in the abundance of its volatile organic compounds (VOCs) at different developmental stages, as well as the molecular mechanisms regulating floral scent biosynthesis, remain unclear.

High-resolution genome assembly and population genetic study of the endangered maple (Sapindaceae): implications for conservation strategies.

Diels (Sapindaceae), a highly threatened maple endemic to the dry-hot valleys of the Yalong River in western Sichuan, China, represents a valuable resource for horticulture and conservation. This study presents the first chromosomal-scale genome assembly of (~626 Mb, 2 = 26), constructed using PacBio HiFi and Hi-C sequencing technologies. Comparative genomic analyses revealed significant recent genomic changes through rapid amplification of transposable elements, particularly long terminal repeat retrotransposons, coinciding with the dramatic climate change during recent uplift of the Hengduan Mountains.

 (Primulaceae), a new species from Sichuan, China.

A new species, W.B.Ju, L.

 (Mazaceae), a new species from Xizang, China.

W.B.Ju, Bo Xu bis & X.

, a new species of Primulaceae from Tibet of China.

We present a description of a newly discovered species, , found in southern Xizang, China. Additionally, we explore distinctive morphological characteristics that aid in its taxonomy. The new species belongs to sect.

 (Primulaceae), a new species of the primrose from Sichuan, China.

This paper describes and illustrates a new species of Primulaceae, from Wolong National Nature Reserve in Sichuan Province, China. It is very rare and currently only known from its type locality. The new species belongs to subsection Chartacea of the section Petiolares on account of lacking bud scales at flowering, being efarinose and having distinct petiolate leaves with more or less rounded lamina.

 (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.

Effects of topological characteristics on rhythmic states of the D-dimensional Kuramoto model in complex networks.

Synchronization is a ubiquitous phenomenon in engineering and natural ecosystems. While the dynamics of synchronization modeled by the Kuramoto model are commonly studied in two dimensions and the state of dynamic units is characterized by a scalar angle variable, we studied the Kuramoto model generalized to D dimensions in the framework of a complex network and utilized the local synchronous order parameter between the agent and its neighbors as the controllable variable to adjust the coupling strength. Here, we reported that average connectivity of networks affects the time-dependent, rhythmic, cyclic state.

Chromosome-level de novo genome assembly and whole-genome resequencing of the threatened species Acanthochlamys bracteata (Velloziaceae) provide insights into alpine plant divergence in a biodiversity hotspot.

The Hengduan Mountains region is an important hotspot of alpine plant diversity and endemism. Acanthochlamys bracteata is a species of a threatened monotypic genus endemic to the Hengduan Mountains. In this study, we present a high-quality, chromosome-level reference genome for A.

(Rosaceae), a new species from the Hengduan Mountains, China.

, a new species from the Hengduan Mountains China, is described and illustrated. It is similar to from China (Yunnan & Xizang), Nepal, and Sikkim in the size of the leaflets, glabrous veins, persistent (sometimes) herbaceous stipules and reddish brown villous inflorescences and red fruits, but differs in its serrate leaflet margins toothed in the distal half or often almost to their base, reddish brown villous to glabrous hypanthium and reddish brown villous infructescences, among other characteristics.

Molecular phylogenetics and historical biogeography of Sorbus sensu stricto (Rosaceae).

Explaining how plants from eastern Asia migrated to other Northern Hemisphere regions is still challenging. The genus Sorbus sensu stricto (including c. 88 species) is considered as a good example to illuminate this scenario, due to the wide distribution in the temperate zone and high diversity in the Himalayas and Hengduan Mountains.
