Relationships Between Expression of Heat Shock Protein Genes and Photosynthetic Behavior During Drought Stress in Plants
… patterns of HSP gene expression during photosynthetic acclimation were examined. One cycle of mild (-1Mpa) followed by two cycles of severe stress (-1.7Mpa) were probed for conditioning effects. Photosynthetic acclimation occurred after the first cycle. No acclimation occurred without …

Influences of elevated atmospheric CO₂ and water stress on photosynthesis and fluorescence of loblolly pine, red maple, and sweetgum
… species in a future elevated CO₂ atmosphere. Photosynthetic light response curves were constructed with a closed photosynthesis system (LI-COR, Inc. Lincoln, NB) in order to investigate the effect of growth in elevated CO₂ (746 μl⁻¹) and ambient CO₂ (379 μl⁻¹) on light responses, and seedlings …

Effects of turbidity on the kelp Ecklonia radiata
… was a primary driver of the morphology, photoacclimation response, distribution, and productivity of E. radiata in the Hauraki Gulf. Photosynthetic acclimation to low light was indicated by higher photosynthetic efficiencies and photosynthetic pigment content occurring at low light sites and …

Regulatory mechanisms underlying C3 carbon and nitrogen metabolism under elevated CO2
… shown to significantly influence the extent of photosynthetic stimulation, photosynthetic acclimation, leaf N status as well as productivity in selected C3 plants under eCO2. Chapter 4 draws inferences from a C-N interaction significant gene regulatory network to predict key transcription …

Growth response and drought susceptibility of forest trees exposed to simulated acidic rain and ozone
… treatments after the drought cycles indicating photosynthetic acclimation to drought stress. During the second drought cycle, Pn was more sensitive to water potential in red spruce and loblolly pine seedlings exposed to 0.10 ppm ozone + pH 3.0 solution compared with seedlings exposed to 0.0 ppm …

Aclimatação da maquinaria fotossintética do cafeeiro cultivado em diferentes níveis de luz e de disponibilidade hídrica
O cafeeiro é originário das florestas tropicais da África, onde é encontrado como vegetação de sub-bosque, desenvolvendo-se sob sombra. No Brasil, no entanto, os cafezais vêm sendo conduzidos quase exclusivamente a pleno sol. Cafezais a pleno sol produzem, na maioria dos casos, mais que os plantios …

Strategies to improve C4 photosynthesis, water and resource-use efficiency under different atmospheres, temperatures, and light environments
… mechanism significantly boosts photosynthetic efficiency and overall productivity, while improving the efficiency with which key inputs such as water or nitrogen are used. Several of the world's most important and productive crops, such as maize, sugarcane, and sorghum, all use …

Inhibition of Canopy Tree Seedlings by Thickets of <I>Rhododendron maximum</I> L. (Ericaceae) in an Eastern Deciduous Forest
… seedlings growing in thickets have lower mid-day photosynthetic rates; 3) <I>Quercus rubra</I> and <I>Prunus serotina</I> seedlings growing within thickets are low light acclimated when compared to seedlings growing in forest without <I>R. maximum</I>; 4) the presence of <I>R. maximum</I> …
