Morphologically, is similar to , but can be easily distinguished from the latter by ovate-lanceolate bracts, purple corolla, and foot-shaped fused lower arms of connective. In addition, is morphologically similar to , but differs by having 3-4-pinnate leave, ovate-lanceolate bracts, puberulent calyx, and longer upper arms of connective.

Preliminary exploration of herbal tea products based on traditional knowledge and hypotheses concerning herbal tea selection: a case study in Southwest Guizhou, China.

Background: Herbal tea usually refers to "beverage plants that do not belong to the genus Camellia", and it holds a significant historical legacy as a traditional beverage among specific regions and ethnic groups. In light of this, our research aims to investigate and analyze the traditional knowledge pertaining to herbal tea plants used by local people in the Qianxinan Buyi and Miao Autonomous Prefecture, Guizhou Province. We also initiated preliminary efforts to create tea products from herbal tea leaves using various processing techniques.

In situ synthesis of self-supporting conductive CuCo-based bimetal organic framework for sensitive nonenzymatic glucose sensing in serum and beverage.

Most MOFs are associated with the inherent defect of low conductivity, limiting their further application in electrochemical sensing. Herein, a self-supporting conductive CuCo-based bimetal organic framework with HHTP as the organic ligand was in situ synthesized on carbon cloth via a one-step hydrothermal method, namely CuCo-MOF/CC. Benefiting from the advantages of electrical conductivity and bimetallic synergies, CuCo-MOF/CC exhibited remarkable electrocatalytic performance toward glucose.

Comparative analyses of Linderniaceae plastomes, with implications for its phylogeny and evolution.

Introduction: The recently established Linderniaceae, separated from the traditionally defined Scrophulariaceae, is a taxonomically complicated family. Although previous phylogenetic studies based on a few short DNA markers have made great contributions to the taxonomy of Linderniaceae, limited sampling and low resolution of the phylogenetic tree have failed to resolve controversies between some generic circumscriptions. The plastid genome exhibits a powerful ability to solve phylogenetic relationships ranging from shallow to deep taxonomic levels.

Companion Plants of Tea: From Ancient to Terrace to Forest.

China is one of the origins of ancient tea gardens, with a long history of tea culture and tea cultivation. Guizhou Province is an important tea production place in southwest China with rich forest tea resources. The purpose of this study is to obtain historical information on companion plants in historical tea gardens and provide a theoretical basis for the sustainable development of forest tea gardens in Guizhou Province.

A ratiometric electrochemical sensing strategy based on the self-assembly of Co NC/CNT and methylene blue for effective detection of the food additive tert-butylhydroquinone.

It is crucial to achieve accurate and rapid detection of tert-butylhydroquinone (TBHQ) in the field of food safety, for the excessive addition of TBHQ in food is harmful to human health and evil to the environment and aquatic life. Therefore, researchers have done a lot of work on signal amplification through nanomaterials to achieve TBHQ detection, but the conventional single-signal detection strategy results in limited accuracy. In this work, an innovative and facile ratiometric electrochemical sensor for TBHQ detection was built based on advanced nanomaterial complexes carbon nanotube-encapsulated Co/nitrogen-doped carbon (Co NC/CNT) and selected internal reference signal methylene blue (MB) enhancing the accuracy by offering effective self-calibration.

A fijiviral nonstructural protein triggers cell death in plant and bacterial cells via its transmembrane domain.

Southern rice black-streaked dwarf virus (SRBSDV; Fijivirus, Reoviridae) has become a threat to cereal production in East Asia in recent years. Our previous cytopathologic studies have suggested that SRBSDV induces a process resembling programmed cell death in infected tissues that results in distinctive growth abnormalities. The viral product responsible for the cell death, however, remains unknown.

Nutrient value of wild fodder species and the implications for improving the diet of mithun () in Dulongjiang area, Yunnan Province, China.

Wild fodder plants are valuable because they provide an important livestock feed resource globally, especially for smallholder farmers, and have important roles in natural resource management. In-depth knowledge of wild forage plants can motivate local people for feed resource and habitat conservation of threatened herbivores such as Mithun (). Mithun occur in small patches in the mountains of Dulongjiang, nearby villagers domesticated this animal but left animal to freely graze in the mountains.

Plants for health: An ethnobotanical 25-year repeat survey of traditional medicine sold in a major marketplace in North-west Yunnan, China.

Ethnopharmacological Relevance: Although quantitative surveys of traditional medicine markets are widely used to gain insights into the economic value, popularity or conservation status of traditional medicinal species, there have been very few repeat surveys. This study is an exception. The research was carried out in Sanyuejie Market in North-west Yunnan Province in China for three reasons.

The implications of ritual practices and ritual plant uses on nature conservation: a case study among the Naxi in Yunnan Province, Southwest China.

Background: Conservation of biodiversity is primary important of today's critically vulnerable environment. Efficient conservation can be possible only with the long-term participation and understanding of the communities. Ritual beliefs of the indigenous people are one of the important tools to understand the local communities and aid the nature conservation.

Prioritizing fodder species based on traditional knowledge: a case study of mithun (Bos frontalis) in Dulongjiang area, Yunnan Province, Southwest China.

Background: Livestock rearing is one of the oldest and most important types of smallholder farming worldwide. The sustainability of livestock production depends on the efficient utilization of locally available resources. Some traditional methods of raising livestock may offer valuable lessons in this regard.

Ethnobotanical study of traditional edible plants used by the Naxi people during droughts.

Background: Since 2009, millions of people have been forced to live under food shortage by the continuous drought in Southwestern China. The market was the primary source of aid grains, and fears that the market will be unable to provide sufficient food make safeguarding food security in the face of climate change crucial. Traditional adaptive strategies of pre-market indigenous people are a potential source of innovation.

Traditional knowledge and its transmission of wild edibles used by the Naxi in Baidi Village, northwest Yunnan province.

Background: The collection and consumption of wild edibles is an important part in livelihood strategies throughout the world. There is an urgent need to document and safeguard the wild food knowledge, especially in remote areas. The aims of this study are to accomplish detailed investigation of wild edibles used by the Naxi in Baidi village and evaluate them to identify innovative organic food products.

Ethnobotanical survey of medicinal dietary plants used by the Naxi People in Lijiang Area, Northwest Yunnan, China.

Background: Food and herbal medicinal therapy is an important aspect of Chinese traditional culture and traditional Chinese medicine. The Naxi are indigenous residents of the Ancient Tea Horse Road, and the medicine of the Naxi integrates traditional Chinese, Tibetan, and Shamanic medicinal systems, however, little is known about the medicinal dietary plants used by the Naxi people, or their ethnobotanical knowledge. This is the first study to document the plant species used as medicinal dietary plants by the Naxi of the Lijiang area.

Finding new sources from "using different plants as the same herb": A case study of Huang-lian in Northwest Yunnan, China.

Ethnopharmacological Relevance: Traditional and local medicinal knowledge would be useful for finding pharmaceutical resources. Ethnopharmacological methods, especially quantitative analysis could help us to pre-screen herbs in field studies. "Using different plants as the same herb" is common in both traditional and local medicinal systems in China.
