1Interactive Effects of Elevated CO_2 and Growth Temperature on the Tolerance of Photosynthesis to Acute Heat Stress in C_3 and C_4 Species显示文摘Determining effects of elevated CO2 on the tolerance of photosynthesis to acute heat-stress (heat wave) is necessary for predicting plant responses to global warming,as photosynthesis is thermolabile and acute heat-stress and atmospheric CO2 will increase in the future.Few studies have examined this,and past results are variable,which may be due to methodological variation.To address this,we grew two C3 and two C4 species at current or elevated CO2 and three different growth temperatures (GT).We assessed photosynthetic thermotolerance in both unacclimated (basal tolerance) and preheat-stressed (preHS=acclimated) plants.In C3 species,basal thermotolerance of net photosynthesis (Pn) was increased in high CO2,but in C4 species,Pn thermotlerance was decreased by high CO2 (except Zea mays at low GT); CO2 effects in preHS plants were mostly small or absent,though high CO2 was detrimental in one C3 and one C4 species at warmer GT.Though high CO2 generally decreased stomatal conductance,decreases in Pn during heat stress were mostly due to non-stomatal effects.Photosystem Ⅱ (PSⅡ efficiency was often decreased by high CO2 during heat stress,especially at high GT; CO2 effects on post-PSII electron transport were variable.Thus,high CO2 often affected photosynthetic theromotolerance,and the effects varied with photosynthetic pathway,growth temperature,and acclimation state.Most importantly,in heat-stressed plants at normal or warmer growth temperatures,high CO2 may often decrease,or not benefit as expected,tolerance of photosynthesis to acute heat stress.Therefore,interactive effects of elevated CO2 and warmer growth temperatures on acute heat tolerance may contribute to future changes in plant productivity,distribution,and diversity.E.

2Variation in Heat-shock Proteins and Photosynthetic Thermotolerance among Natural Populations of Chenopodium album L.from Contrasting Thermal Environments:Implications for Plant Responses to Global Warming显示文摘Production of heat-shock proteins (Hsps) is a key adaptation to acute heat stress and will be important in determining plant responses to climate change.Further,intraspecifc variation in Hsps,which will influence species-level response to global warming,has rarely been examined in naturally occurring plants.To understand intraspecific variation in plant Hsps and its relevance to global warming,we examined Hsp content and thermotolerance in five naturally occurring populations of Chenopodium album L.from contrasting thermal environments grown at low and high temperatures.As expected,Hsp accumulation varied between populations,but this was related more to habitat variability than to mean temperature.Unexpectedly,Hsp accumulation decreased with increasing variability of habitat temperatures.Hsp accumulation also decreased with increased experimental growth temperatures.Physiological thermotolerance was partitioned into basal and induced components.As with Hsps,induced thermotolerance decreased with increasing temperature variability.Thus,populations native to the more stressful habitats,or grown at higher temperatures,had lower Hsp levels and induced thermotolerance,suggesting a greater reliance on basal mechanisms for thermotolerance.These results suggest that future global climate change will differentially impact ecotypes within species,possibly by selecting for increased basal versus inducible thermotolerance.Deepak Barua Scott A.Heckathorn James S.Coleman 2008Journal of Integrative Plant Biology2008,50,11:3
