Why flowers close at noon? A case study of an alpine species Gentianopsis paludosa (Gentianaceae). [PDF]
Ecol Evol, 2022 In this work, we report a repeatable floral closure rhythm, that is, open in the morning but close in early afternoon, first in an alpine species belonging to Gentianaceae. By monitoring the petal movement under treatments of changed environmental factors, detecting the microenvironment changing inside and outside flowers, and measuring the seed ...

Effects of ambient climate and three warming treatments on fruit production in an alpine, subarctic meadow community. [PDF]
Am J Bot, 2021 Premise Climate change is having major impacts on alpine and arctic regions, and inter‐annual variations in temperature are likely to increase. How increased climate variability will impact plant reproduction is unclear. Methods In a 4‐year study on fruit production by an alpine plant community in northern Sweden, we applied three warming regimes: (1 ...

Research Progress on Anti-Inflammatory Effects and Mechanisms of Alkaloids from Chinese Medical Herbs. [PDF]
Evid Based Complement Alternat Med, 2020 As the spectrum of diseases keeps changing and life pace keeps going faster, the probability and frequency of diseases caused by human inflammatory reactions also keep increasing. How to develop effective anti‐inflammatory drugs has become the hotspot of researches.

Intraspecific trait variation in alpine plants relates to their elevational distribution
Journal of Ecology, Volume 110, Issue 4, Page 860-875, April 2022., 2022 Plant species (☆) from lower elevations and those with larger range sizes (pale diamonds) show greater intraspecific trait variation (e.g. plant height, right panel), which may indicate a greater ability to respond to environmental changes. Also, larger trait variation of species from lower elevations may indicate stronger competitive ability of ...

Antifungal Compounds against Candida Infections from Traditional Chinese Medicine. [PDF]
Biomed Res Int, 2017 Infections caused by Candida albicans, often refractory and with high morbidity and mortality, cause a heavy burden on the public health while the current antifungal drugs are limited and are associated with toxicity and resistance. Many plant‐derived molecules including compounds isolated from traditional Chinese medicine (TCM) are reported to have ...

Silencing Nicotiana attenuata LHY and ZTL alters circadian rhythms in flowers. [PDF]
New Phytol, 2016 Summary The rhythmic opening/closing and volatile emissions of flowers are known to attract pollinators at specific times. That these rhythms are maintained under constant light or dark conditions suggests a circadian clock involvement. Although a forward and reverse genetic approach has led to the identification of core circadian clock components in ...

Phylogenetic relationships and sectional delineation within Gentiana (Gentianaceae)
TAXON, Volume 69, Issue 6, Page 1221-1238, December 2020., 2020 Abstract Gentiana is a sub‐cosmopolitan temperate genus among the most species‐rich in Gentianaceae. Although molecular data (produced via Sanger sequencing) allowed the resolution of phylogenetic relationships between Gentiana and other genera in subtribe Gentianinae, the validity of sections within the genus remains largely untested.

Ecology and Evolution, Volume 7, Issue 18, Page 7503-7514, September 2017., 2017 The objective of our study was to determine whether R. aureum community could shape a special microbial community and investigate the interspecific relationship of above‐ground plants. R. aureum could shape a special soil microbial community structure for growth and expansion and compete with associated species. Abstract Rhododendron aureum Georgi is a

The Structure and Biological Activities With Health Benefits of Luteolin Glycosides From Plants
The Scientific World Journal, Volume 2025, Issue 1, 2025.Luteolin, a flavonoid in the class of flavones, is found in various plant families. Luteolin is present in plants as both aglycone and glycosides. Luteolin glycosides are found in plants more often than aglycone. In this review, the structure, metabolism, biological activities, and health benefits of luteolin glycosides present in plants are summarized
