Rice genetically engineered to resist heat waves can also produce up to 20% more grain

From Science Mag By Erik Stokstad Apr. 21, 2020 , 1:10 PM … “This is exciting news,” says Maria Ermakova of Australian National University, who works on improving photosynthesis. The genetic modification worked in three kinds of plants—a mustard that is the most common plant model, tobacco, and rice, suggesting any crop plant could be…

Precipitation will be essential for plants to counteract global warming

New study first to demonstrate that the balance between soil water and energy input into an ecosystem determines whether its plant growth is limited by precipitation or by temperature Columbia University School of Engineering and Applied ScienceShare Print E-Mail New York, NY–April 13, 2020–Photosynthesis on Earth is regulated by plant phenology–how plant life cycles interact with the…

Study identifies new temperature sensing mechanism in plants

Phytochrome foci have different behaviors at different temperatures and types of light University of California – Riverside A protein called phytochrome B, which can sense light and temperature, triggers plant growth and controls flowering time. How it does so is not fully understood. In a paper published in Nature Communications, a group of cell biologists…

Carbon Sequestration

Guest post by Rud Istvan, As most WUWT readers know, the issue of carbon sequestration is an important but largely IPCC undiscussed ‘anthropogenic global warming’ question. I got to thinking about it again as a result of the Australian brush fires that are dramatically releasing sequestered brush carbon. And it has been years since the…

‘Artificial leaf’ successfully produces clean gas

From Techxplore by University of Cambridge A widely-used gas that is currently produced from fossil fuels can instead be made by an ‘artificial leaf’ that uses only sunlight, carbon dioxide and water, and which could eventually be used to develop a sustainable liquid fuel alternative to petrol. The carbon-neutral device sets a new benchmark in…

Earth system models underestimate carbon fixation by plants in the high latitudes

From Nature Communications. Abstract Most Earth system models agree that land will continue to store carbon due to the physiological effects of rising CO2 concentration and climatic changes favoring plant growth in temperature-limited regions. But they largely disagree on the amount of carbon uptake. The historical CO2 increase has resulted in enhanced photosynthetic carbon fixation…

The Gas of Life

By Jim Goodridge  – former California State Climatologist Photosynthesis simply stated is 6CO2 + 6H2O + photons = C6H12O6+6O2. It is suggested by the relative abundances of atmospheric CO2 and O2, That CO2 is a quite active material and it is always in short supply. Plant growth is basically the chemical reaction of storing solar…
