The cap-binding proteins CBP20 and CBP80 have well-established roles in RNA metabolism and plant growth and development. Although these proteins are thought to be involved in the plant’s response to environmental stress, their functions in this process are unclear. Here, we demonstrated that Arabidopsis cbp20 and cbp80 null mutants had abnormal leaves and flowers and exhibited increased sensit...
The diversification and evolution of floral traits are driven by both biotic and abiotic agents. Among the most well-studied agents is rain, which can wash away pollen grains, reduce pollen viability and dilute nectar thus affecting the reproductive fitness directly or indirectly. Strong ultraviolet radiation (especially UV-B radiation) is also known to reduce pollen viability, and strong UV-B ...
Schisandra chinensis (Wuweizi) is a tonic in traditional Chinese herbal medicine that has been widely used for thousands of years to treat insomnia, remove fatigue, sedate and enhance mental and intellectual functions. While most researches focus on the pharmacological activity of the lignans of S. chinensis for the effects on the central nervous system (CNS), the study about the function and m...
Mushrooms in the basidiomycete family Boletaceae are ecologically and economically very important, and have long attracted the attention of mycologists from different parts of the world. Some of these boletes have great economic, dietary, and health value, and some other boletes are poisonous, predominantly causing gastrointestinal symptoms of nausea and violent vomiting if eaten raw or fried. ...
Recently, the Research Group in Fungal Diversity and Molecular Evolution, Kunming Institute of Botany, the Chinese Academy of Science, has described a new genus, Cibaomyces Zhu L. Yang, Y.J. Hao & J. Qin, of Physalacriaceae. The type species of this genus is Cibaomyces glutinis Zhu L. Yang, Y.J. Hao & J. Qin. The known distribution is southwestern China and northern Japan. “Cibao-” refers to ...
Research Group of the Plant Evolution in the Karst Plant in Kunming Institute of Botany,Chinese Academy of Sciences, achieved some new findings about the endemic genus Petrocodon in Gesneriaceaeto Chinese Karst regions. The main contentsare following:
Firstly, three new species of Gesneriaceae, Petrocodon ainsliifolius, Petrocodon lithophilus, Petrocodon viridescens, from limestone areas of...
Both nitric oxide (NO) and hydrogen peroxide (H2O2) are important signals that mediate plant response to environmental stimulation. Their role in plants’ allelopathic interactions has also been reported, but the underlying mechanism remains little understood. p-Hydroxybenzoic acid (pHBA) has been proposed to be an allelopathic chemical.
Recently, Dr. GUAN Yanlong advised by Profs. HU Xiang...
Heteromorphy in flowers has a profound effect on breeding patterns within a species, but little is known about how it affects reproductive barriers between species. The heterostylous genus Primula is very diverse in the Himalaya region, but hybrids there have been little researched.
Chloroplast sequencing, AFLP (amplified fragment length polymorphism) markers and morphological comparisons w...
New genes are critical for speciation, evolution and adaptation of species. Horizontal gene transfer (HGT) is an important way of acquiring new genes and its occurring scales and biological significance have been extensively investigated in prokaryotes and unicellular eukaryotes. In higher plants, HGT events have been found mainly between the organelle genomes from different plants and were rar...
