Hippophae gyantsensis is a dioecious plant endemic to the Qinghai-Tibet Plateau and is significant for ecological restoration and sand stabilization. Its fruit is rich in bioactive compounds that offer economic potential. However, the inability to distinguish sexes before flowering and prolonged maturation hinder breeding and cultivation.

, belonging to the Elaeagnaceae family, is an endemic plant species of the Qinghai-Tibet Plateau, valued for its remarkable ecological restoration capabilities, as well as medicinal and edible properties. Despite being acknowledged as a useful species, its mitochondrial genome data and those of other species of the Elaeagnaceae family are lacking to date. In this study, we, for the first time, successfully assembled the mitochondrial genome of , which is 464,208 bp long and comprises 31 tRNA genes, 3 rRNA genes, 37 protein-coding genes, and 3 pseudogenes.

Hippophae tibetana, one of the highest-altitude woody plants endemic to the Qinghai-Tibet Plateau, primarily thrives on riverbanks formed by glacial meltwater. As a dioecious species, it demonstrates significant ecological and economic value in extreme alpine environments. However, the lack of sex identification techniques outside of the flowering period severely limits research on sex ratio, differentiation, and breeding.

Prain 1906, a national second-class rare and endangered plant, is reported here for the first time for its complete chloroplast genome. The genome is 153,290 bp in length, comprising a large single-copy region (LSC, 83,918 bp), a small single-copy region (SSC, 17,740 bp), and two inverted repeat sequences (IRa and IRb, each 25,816 bp). The overall GC content is 38.

Chemical compositions of crops are of great agronomical importance, as crops serve as resources for nutrition, energy, and medicines for human and livestock. For crop metabolomics research, the lack of crop reference metabolome and high-quality reference compound mass spectra, as well as utilities for metabolic profiling, has hindered the discovery and functional study of phytochemicals in crops. To meet these challenging needs, we have developed the Crop Metabolome database (abbreviated as CropMetabolome) that is dedicated to the construction of crop reference metabolome, repository, and dissemination of crop metabolomic data, and profiling and analytic tools for metabolomics research.

Article Synopsis
  • Some plants have seeds enclosed by a protective layer called a pericarp, which may influence their germination strategies, particularly in relation to flowering time and seed mass.
  • In a study conducted in a diverse alpine meadow in China, researchers found that the speed of germination (MGT) varies based on whether seeds have a pericarp or not.
  • Seeds with pericarps germinated faster when flowering occurred earlier, while those without pericarps germinated quicker if they were smaller, indicating different dependency on maternal effects for germination strategies.

Background: If chronic allograft nephropathy can be detected early and treated, the long-term survival rate of the transplanted kidney may be effectively improved.

Purpose: To compare the application value of real-time sound touch elastography (STE), strain elastography, and color Doppler flow imaging in evaluating chronic kidney disease of transplanted kidneys.

Materials And Methods: A total of 101 patients with renal transplantation were divided into a normal group (serum creatinine <134 mol/L, 58 patients) and a chronic allograft nephropathy group after renal transplantation over 6 months (serum creatinine >134 mol/L, 43 patients).

Article Synopsis
  • The East Himalaya-Hengduan Mountains (EHHM) area has seen significant diversification due to recent geological uplift and climate variations, though the mechanisms behind this are still unclear.
  • Researchers utilized chloroplast and nuclear DNA markers to analyze how geological and ecological factors influenced the genetic structure of a specific species within the region.
  • The study found strong genetic differentiation correlating with climatic conditions rather than geographical barriers, suggesting that fluctuating climates during the Quaternary period played a critical role in the species' evolution and population dynamics in the EHHM.

Background And Aims: Many plant taxa in the Qinghai-Tibetan Plateau (QTP) and the Hengduan Mountains (HM) radiated rapidly during the Quaternary but with frequent secondary contact between diverging populations. Incomplete lineage sorting and introgressive hybridization might be involved during the rapid radiation, but their effects on phylogeography have not been fully determined.

Methods: We investigated the chloroplast DNA (cpDNA)/internal transcribed spacer (ITS) sequence variations of 611 samples of Rhodiola bupleuroides, R.

Background: Understanding how organisms evolve and adapt to extreme habitats is of crucial importance in evolutionary ecology. Altitude gradients are an important determinant of the distribution pattern and range of organisms due to distinct climate conditions at different altitudes. High-altitude regions often provide extreme environments including low temperature and oxygen concentration, poor soil, and strong levels of ultraviolet radiation, leading to very few plant species being able to populate elevation ranges greater than 4000 m.

Study Objectives: To examine the association between sleep structure and amnesic mild cognitive impairment (aMCI) in patients with insomnia disorder.

Methods: A total of 256 patients with insomnia disorder were diagnosed by neurologists, 45 of whom were diagnosed with aMCI according to the Petersen criteria, and 45 participants with intact cognition were chosen as controls matched for age and education. A case-control study was conducted to compare sleep structure between aMCI and control patients with insomnia disorder.

Rnd3, a Rho GTPase, is involved in the inhibition of actin cytoskeleton dynamics through the Rho kinase-dependent signaling pathway. We previously demonstrated that mice with genetic deletion of developed a markedly larger brain compared with wild-type mice. Here, we demonstrate that knockout mice developed an enlarged subventricular zone, and we identify a novel role for Rnd3 as an inhibitor of Notch signaling in neural stem cells.

Wu hypothesized that the Tibetan flora originated mostly from the paleotropical Tertiary flora in the Hengduan Mountains by adapting to the cold and arid environments associated with the strong uplift of the Qinghai-Tibet Plateau (QTP). Here, we combine the phylogeographic history of Sophora moorcroftiana with that of Sophora davidii to explore the speciation of S. moorcroftiana to test this hypothesis.

Microrefugia at high altitudes or high latitudes are thought to play an important role in the post-glacial colonization of species. However, how populations in such microrefugia have responded to climate changes in alternating cold glacial and warm interglacial stages remain unclear. Here we present evidence to indicate the Rongbuk Valley of the Mt.
