Analysis of the impact of climate change on the distribution and active compound content of the plateau medicinal plant Nardostachys jatamansi (D. Don) DC
“…We predicted the changes in the suitable habitat of A. amurensis for the period 2041-2060 and 2081-2010 based on two climate scenarios. Numerous reports indicated that future climate change will lead to loss of suitable habitat for species such as the Coptis species (Li et al, 2020), Oroxylum indicum (Kumar et al, 2021), and Nardostachys jatamansi (Wen et al, 2022). The spread of habitat evolved differently under various future climate scenarios.…”

Adonis amurensis Regel et Radde is an early spring plant in northeastern China that has great ornamental value because it blooms before other plants have sprouted. It has not been used to its full potential due to environmental restrictions on its growth. It will be extremely important for its application to comprehend the possible habitat of A. amurensis and the critical environmental factors controlling its distribution under current and future climatic scenarios. In this work, two climate change scenarios of 2041–2060 and 2081–2100 were utilized to predict the suitable habitat of A. amurensis. The results showed that the suitable habitat was mainly distributed along the Changbai Mountains, with a total area of 303,090 km2, and the potential and high‐potential habitat area were 141,218 and 161,872 km2, respectively. In the future climate scenarios, the suitable habitat of A. amurensis was still distributed along the Changbai Mountains, but the area was reduced. In ssp126 and ssp585 scenarios of 2041–2060 and 2081–2100, the area was reduced by 7.13% and 22.34% and 18.66% and 8.09%, respectively. The reduced suitable habitat was mainly located in central Heilongjiang (southeastern Xiao Xing'an Ling), central Jilin, and northeastern Liaoning. The suitable habitat was significantly influenced by precipitation, mainly affected by annual precipitation, followed by precipitation seasonality, soil surface pH, and slope. The results of this study can serve as empirical support for the artificial cultivation, ecological restoration, and long‐term use of A. amurensis.

Leonurus japonicus Houtt. (Labiatae), a perennial herb, is used to treat cardiovascular, uterine, and gynecological diseases. In the present study, a phylogenetic tree was constructed based on the ITS + psbA-trnH + rbcL + rpoB concatenation sequence, and partial least squares-discriminant analysis (PLS-DA) was performed based on high-performance liquid chromatography. The phylogenetic tree and PLS-DA were combined to correlate genetic and chemical differences among L. japonicus derived from different origins. The results showed that the concatenation sequence could distinguish among L. japonicus from different origins. Moreover, chemical analysis revealed intergroup differences, but the results were not of su ciently high quality as that of molecular phylogeny. Furthermore, the results of combined chemical and phylogenetic analyses suggested that differences in metabolites are in uenced by not only genetic differences but also environmental factors. These results provide valuable information for the arti cial cultivation of L. japonicus and new ideas for improving its quality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
