Mountain ecosystems harbor high levels of biodiversity, but the genetic mechanisms underlying adaptation to harsh alpine conditions remain largely unknown. Bergenia purpurascens (Saxifragaceae) is an important endemic species Himalaya-Hengduan Mountains (HHM), with this being used as a source medicine and ornamental plant. In study, we generated high-quality genome assembly comprising scaffolds representing 17 chromosomes, total length 650.70 Mb scaffold N50 34.19 Mb. A 45,841 protein-coding genes were annotated, 10,797 noncoding RNAs identified. Repeat sequences accounted for 56.72% genome. The reference B. serves valuable resource studying bergenin biosynthesis, understanding plants environments.

Camphora longepaniculata is an endangered evergreen tree listed as National Class II Protected Tree Species in China, highly valued for its medicinal and economic importance. Currently, research on this species has primarily focused pharmaceutical properties, while potential distribution responses to climate change remain insufficiently explored. In study, 36 valid occurrence records 11 environmental variables were utilized predict assess response future scenarios. The MaxEnt model revealed that the current of C. largely aligns with predicted suitable habitats, primary range located Sichuan Province. Furthermore, identified habitats be predominantly concentrated Shaanxi Provinces under change. Among variables, annual precipitation (bio12), minimum temperature coldest month (bio6), elevation (dem) most influential, collectively contributing over 70% model’s predictive accuracy. Future projections compared suggest a northward expansion longepaniculata, although Province core habitat Kernel density analysis points indicated largest concentration near Basin, reinforcing importance region stronghold species. Based results kernel analysis, situ conservation, artificial cultivation, establishment wild protected areas local germplasm banks are recommended stable, such parts Yunnan Guizhou Provinces.

ABSTRACT Climate change is an important driver of the potential distribution changes plants. However, wide‐ranged and narrow‐ranged species in response to climate were still controversial. An epiphytic orchid genus Holcoglossum a key group address this issue, with about 30% widely distributed Asian mainland, while others are only narrowly special mountains. Combining species' occurrences, environmental variables, Human Footprint data, we analyzed predictor variables predicted distributions centroid shifts four from Pliocene future using maximum entropy (MaxEnt) model. Our results showed that seven (except H. subulifolium ) mainly impacted by precipitation warmest quarter future. From present, contracted. present (SSP2‐4.5, 2090), two ( flavescens , himalaicum would contract, whereas other expand; kimballianum wangii expand. The centroids three migrate southwards amesianum ), have nearly no migration; pumilum quasipinifolium westwards. We found vulnerability might be unlinked their current range phylogenetic relationships. This study provides new insights for conservation species.
