Extracellular calmodulin (ExtCaM) exerts multiple functions in animals and plants, but the mode of ExtCaM action is not well understood. In this paper, we provide evidence that ExtCaM stimulates a cascade of intracellular signaling events to regulate stomatal movement. Analysis of the changes of cytosolic free Ca2+ ([Ca2+]cyt) and H2O2 in Vicia faba guard(More)
To effectively treat articular cartilage defect with tissue engineering there is an urgent need to develop safe and cheap drugs that can substitute or cooperate with growth factors for chondrogenesis promotion. Here, we demonstrate the chondrogenic effect of icariin, the major pharmacological active constituent of Herb Epimedium (HEP). Rabbit chondrocytes(More)
In the present experiment, we mainly discussed the function mechanism between the humic acid and a new kind of fungicide Pyrimorph, aiming to play a positive role in the reduction of contamination caused by pesticides on environment. After the disposition step by step, the humic acid was separated into three parts. Then IR and fluorescence analytical(More)
The respiratory chain cytochrome bc1 complex (cyt bc1) is a major target of numerous antibiotics and fungicides. All cyt bc1 inhibitors act on either the ubiquinol oxidation (QP) or ubiquinone reduction (QN) site. The primary cause of resistance to bc1 inhibitors is target site mutations, creating a need for novel agents that act on alternative sites within(More)
The molecular recognition of fungicide of kresoxim-methyl with beta-cyclodextrin (beta-CD), methyl-beta-cyclodextrin (RAMEB)and hydroxypropyl-beta-cyclodextrin (RAMEB) was investigated by using UV-Vis spectroscopy analysis. The effect of temperature and polarity of solvent on the recognition interaction was studied. The driving force and the possible(More)
