Alternaria alternata is a necrotrophic pathogenic fungus, causing severe lost in many economic plants such as potato, pear, citrus, and tobacco. By using wild tobacco Nicotiana attenuata as a model plant, researchers in Kunming Institute of Botany find that host plants can defend themselves by closing their stomata by quickly activation of ABA signaling and mitogen activated protein kinase 4.

Camellia taliensis (Theaceae) is endemic from western Yunnan province of China to northern Myanmar. Its leaf has been collected to produce beverage that is alike the tea from C. sinensis var. assamica but has its specific characteristic constituents. The tea probably made from C. taliensis was recorded 1300 years ago, and this species has been cultivated throughout western Yunnan at least for h...
Archaea lived in extreme environments (alkaline, acidic, extremely cold, extremely hot, hypersaline), represent one kind of special microorganisms. Haloarchaea belongs to the domain of Archaea, were widely distributed in hypersaline environments. It contains many applications in medicinal and bio-chemical industries. The researches on the halo-plasmid will pave the way for the exploitation and ...
Plants may adapt to alpine habitats by specialization in the reproductive strategy and functional aspects of their flowers and pollination systems. Alpine habitats reduce the opportunities for cross-pollination in a relatively high proportion of alpine plant species, and self-pollination may be favored in these adverse conditions.
Recently, Drs. AI Honglian and ZHOU Wei advised by Profs. WA...
Exploration of natural sources for novel bioactive compounds has been an emerging field of medicine over the past decades, providing drugs or lead compounds of considerable therapeutic potential. This research has provided exciting evidence on the isolation of microbe-derived metabolites having prospective biological activities. Mushrooms have been valued as traditional sources of natural bioac...
Pedicularis (Orobanchaceae) comprises approximately 600-800 species, one of the largest genera of flowering plants in the north temperate zone. About two thirds of these species are confined to the region of the Hengduan Mountains in southwestern China, which represents one of the main centers of species diversity and endemism for this genus. Pedicularis section Cyathophora is characterized by ...
Platinum-based drugs have become fundamental components of standard chemotherapy regiments, and are widely used in antitumor therapy of testicular and ovarian tumors, lung and colorectal carcinomas. Despite the therapeutic benefit, the efficacy of platinum-based treatment regiments is considerably compromised not only by severe side-effects but also by insurmountable cross-resistance.
With ...
The temperate bamboos are a morphologically diverse grass lineage with approximately 32 genera and 600 species distributed primarily in the North Temperate Zone or at high elevations in tropical regions of both the northern and southern hemispheres. There are approximately 430 species distributed in East Asia, of which 180 are endemic to Southwestern China. Previous phylogenetic studies strongl...
Chukrasia A. Juss. is a medium to large tree genus comprising only C. tabularis and C. tabularis var. velutina, distributed mainly in South and Southeast Asia. The timber of Chukrasia is high-grade wood famous all over the world. Besides, being huge and leafy, Chukrasia is often used as roadside or landscape trees.
Genus Chukrasia excels at generate diverse phragmalin limonoids with novel s...
