With the increase of the fields that the government involves and social cooperation negotiating,there are more and more evolutionary games under three asymmetric parties.But there is little research about this kind of game at home and abroad.This is clearly not conductive to properly explain and predict real-life behaviors of three asymmetric evolutionary game.Because of this,based on the strategic adjustment process,this paper establishes the dynamic equations of 2×2×2 asymmetric evolutionary game and classifies qualitative property to analyse behaviors of the three asymmetric parties.We give stable strategies of the three parties under different circumstances.At the same time,we use three-dimensional figures to show the results.This paper has a certain significance to analyse the game behaviors of three asymmetric parties.

Individual difference is a very important factor that may greatly affect the process of second language acquisition. Indi?vidual difference factors include age, gender, language aptitude, motivation, personality, learning style and learning strategies, the main of which is learning motivation. The paper mainly deals with the domestic and foreign classifications of motivation, affect?ing factors and influences of motivation on second language acquisition and the strategies of stimulating learning motivation.

This paper breaks the traditional model of pairwise game.Based on replicated dynamic method of evolutionary game,we build the evolutionary game model for governments、enterprises and citizens in network false information.In different strategies,we analyse their respective cost and benefits and study the game status by evolutionary game theory.We get stable strategies of the three parties under different strategy combinations and use three-dimensional figures to show the results.The game analysis shows that reducing the cost of monitoring rumors and increasing punishment can promote governments to establish network monitoring systems and curb the spread of false information on the web.For citizens,their ultimate evolutionary game strategy is that they will not buy the products of the enterprises who spread false information.

【Objective】Phospholipase C(PLC) was investigated in response to ParA1,a protein elicitor from Phytophthora parasitica,and could trigger cell death and defense responses in tobacco suspension cells.【Method】Using a pharmacological approach,tobacco suspension cells pretreated with PLC inhibitors(neomycin and U73122) in ParA1-induced cells were used to compare cell death and a series of defense responses.【Result】Tobacco suspension cells treated with ParA1 resulted in defense responses,such as hypersensitive cell death,an oxidative burst,alkalization of the extracellular medium,expression of 5 defense-related genes and accumulation of scopoletin,defense-related genes hin1,hsr203J,PR-1a,PR-1b and PAL were expressed in ParA1-induced cells.Cell death induced by ParA1 was entirely inhibited by the addition of U73122,a PLC specific inhibitor. Oxidative burst,alkalization of the extracellular medium,expression of 5 defense-related genes and scopoletin accumulation was significantly suppressed by U73122,respectively.【Conclusion】PLC is required for ParA1-mediated cell death and defense response in tobacco suspension cells which may involve in signal transduction.

The effects of riboflavin on defense responses and secondary metabolism in tobacco (Nicotiana tabacum cv. NC89) cell suspensions and the effects of protecting tobacco seedlings against Phytophthora parasitica var. nicotianae and Ralstonia solanacearum were investigated. Defense responses elicited by riboflavin in tobacco cells included an oxidative burst, alkalinization of the extracellular medium, expression of 4 defense-related genes with different kinetics and intensities, and accumulation of 2 total phenolic compounds, scopoletin and lignin. When applied to tobacco plants challenged by P. parasitica and R. solanacearum, riboflavin treatment resulted in 47.9% and 48.0% protection, respectively. These results suggest that riboflavin can both induce a series of defense responses and secondary metabolism in cell suspensions and protect tobacco against P. parasitica and R. solanacearum.

Phospholipase D (PLD) plays an important role in plants,including responses to abiotic and biotic stresses.Effect of PLD signaling in tobacco suspension cells induced by ParA1,a proteinous elicitor from Phytophthora parasitica,was elucidated.Via a pharmacological approach,tobacco suspension cells treated with PLD inhibitors in ParA1-induced cells was used to compare changes in defense responses.Hypersensitive cell death,hydrogen peroxide and scopoletin accumulation induced by ParA1 were strongly inhibited by 1-butanol,a transphosphatidylation substrate,while treatment with 2-butanol had much less effect.Additionally,treatment with 1-butanol and 2-butanol had inhibitory effect in a dose-dependent manner.In contrast,in ParA1-treated cell suspensions,tert-butanol,used as a negative control,had no inhibitory effect.These results suggest that ParA1-mediated pathway needed PLD signaling in tobacco suspension cells.

Alternaria longipes is the causal agent of tobacco brown spot, a world-wild tobacco disease. Based on Czapek medium supplemented with CaCO3 and apple cutin, the liquid fermentation conditions were optimized in order to acquire higher cutinase activity. Optimum culture time, temperature and pH were 8 d, 25 ℃ and 5.5, respectively; and optimum carbon and nitrogen sources were dextrose and maltose instead of NaNO3. According to this fermentation and orthogonal test, the optimum composition of culture medium included dextrose 3%, casein 1%, Tween-80 0.3%. A 11.0-fold higher cutinase activity was obtained compared to the basal medium and the enzyme activity was enhanced from 15.8 U/mL to 175.2 U/mL.

Cutinase from Alternaria longipes was purified and characterized.A.longipes was grown in a li-quid culture medium containing apple cutin as the inducer.After 8 d of growth,the cutinase was purified through ammonium sulphate precipitation,DEAE(diethylaminoethyl) Sepharose,Sephacryl S-100 HR,and Phenyl-Sepharose 6 fast flow(high sub).A single band was observed by SDS-PAGE,corresponding to a molecular weight of 59.5 kDa.Optimum temperature and pH for the cutinase activity were 35℃ and pH 9.0,res-pectively.The enzyme activity was stable within 20℃-40℃ and pH 4.0-10.0.Na+,Cu2+ and Mn2+ could partially inhibit the cutinase activity.
