Wheat Tolerance to Low Temperature Stress is Enhanced by Elevated CO2 (29 March 2021)
Elevated CO2 improved the low temperature tolerance of wheat by (1) maintaining stability of the chloroplast ultrastructure, (2) enhancing activities of antioxidant enzymes and concentrations of osmotic substances and (3) modifying the sucrose metabolism in leaves...

CO2 Enrichment Enhances the Growth and Quality of Tomato Fruit
(26 March 2021)
In developing a system that supplemented CO2 in greenhouse crop production systems via the fermentation of agriculture organic waste, the authors of this study were able to improve tomato growth and yields, while also improving fruit quality...

The Impact of CO2 on the Growth and Yield of Two Soybean Cultivars
(24 March 2021)
In the future we can expect significantly higher soybean biomass and seed yield, courtesy of the air's increasing CO2 concentration. And these enhancements will occur with little change in seed mineral concentration, but large increases in seed mineral content...

Soil Carbon and Nitrogen Dynamics in a Desert Ecosystem under Elevated CO2 (22 March 2021)
After ten years of experimental treatment it was found that elevated CO2 increased both the soil organic carbon and total nitrogen contents of a Nevada, USA, desert ecosystem, portending a continued and growing accumulation of the soil carbon sink that is not constrained by nitrogen limitations...

Projecting Biomass Changes in Africa for the End of the 21st Century
(19 March 2021)
In this model-based analysis, the positive impacts of CO2 enrichment on 21st century African terrestrial biomass are more than capable of overpowering any growth retarding impacts of future climate, even under the worst-case RCP8.5 scenario...

Plant Growth Database (18 March 2021)

Impacts of Ocean Acidification and Warming on a Crustose Coralline Algae (17 March 2021)
Examined alone, ocean acidification negatively impacted coralline algal productivity and growth. But when examined in concert with ocean warming the negative effects of ocean acidification were counterbalanced by positive effects induced by warmer temperatures, indicating the overall net impact of ocean acidification and warming on this crustose coralline algae species is no impact...

Using RNA Sequencing to Understand How Elevated CO2 Stimulates Growth in Strawberry (8 March 2021)
Analysis of differentially expressed genes revealed elevated CO2 enhanced the biosynthesis of metabolism-promoting growth hormones, accelerated the process of converting active chemical energy into stabilized chemical energy, and increased the transport of photosynthetic products, all of which changes help explain the increase in net photosynthesis and accelerated leaf growth observed under elevated CO2 in this study...

Natural pH Fluctuations at Three Great Barrier Reef Sites
(5 March 2021)
Large daily seawater pH fluctuations from 0.1 to 0.2 pH units observed over 9 days in the Austral winter lead the authors of this paper to caution that "studies on the physiological effects of ocean acidification on shallow nearshore organisms should try to include fluctuating treatments when drawing conclusions about the future impacts of ocean acidification"...
