2016 “How Plants Work” News Highlights – August

plantguy January 8, 2017 January 8, 2017CO2, Ecological Physiology, Plant Development, Plant Evolution 0

From How Sunflowers Track The Sun To Where Strawberries Came From The eighth month of the year may be when many people are on holiday (at least in the Northern Hemisphere). But plant science news didn’t take a holiday. Indeed, there were so many popular reports published last August, it…

2016 “How Plants Work” News Highlights – April

plantguy January 4, 2017 January 5, 2017CO2, Photosynthesis, Plant Signaling, Secondary Compounds 0

From Cancer-Fighting Plants To Cadmium-Sniffing Moss Sadly, those who teach classes about plant physiology often feel the need to justify why plants are important. That’s how I usually began the first lecture in my Botany and Plant Physiology courses back in the day when I was boring undergraduate students. Most…

Will Frenzied Plant Growth Mitigate Global Warming?

plantguy December 30, 2015 January 1, 2016CO2, Photosynthesis, Plant Cell Walls, Plant Stress 0

Out-Of-Control Plants? A couple of reports in the science news a few years ago seemed to suggest that one way to cope with global climate change may be unbridled plant growth. One such report involved the discovery of a cellular regulator for the synthesis of cellulose by plant cells. The…

Is It Time To Abandon Growing Crops For Biofuels?

plantguy February 9, 2015 July 28, 2015CO2, Plant Science 1

Plants – Food Versus Fuel A recently published report has pounded another nail in the biofuels coffin. This report, published by the World Resources Institute provides evidence that governments have made a mistake by supporting the large-scale conversion of plants into fuel. “Turning plant matter into liquid fuel or electricity…

Can We Bioengineer Crop Plants For A High-CO2 World?

plantguy October 7, 2014 October 7, 2014CO2, Photosynthesis, Plant Genetic Engineering 0

We’re In A Jam Let’s face it, humanity is NOT going to back off anytime soon on it’s production of greenhouse gases, especially carbon dioxide from the combustion of fossil fuels. Just last year, for example, atmospheric CO2 emissions increased at their fastest rate for 30 years. So, how are…

Back To The Eocene?

plantguy September 6, 2014 September 8, 2014CO2, Ecological Physiology, Plant Evolution 0

From Anthropocene To Eocene II? A mountainside near where I live gave way in January 2009 (as a result of torrential rains) resulting in Racehorse Creek rock slide. This landslide revealed a treasure-trove of fossils, mainly 55-million-year old fossils of plants that were alive during the Eocene. Most interestingly, perhaps,…

The “Anthropocene” – What Will Be Its Most Profound Effect On Plants?

plantguy August 9, 2014 October 10, 2014CO2, Ecological Physiology, Plant Stress 1

By 2050, What Will Be The Greatest Human Impact on Plants? I first encountered the term “anthropocene” back in 2007 when I was writing a manuscript regarding some of our research in Yellowstone National Park (see Ref. 1 below). A more detailed view regarding the nature and implications of the…

Your House Plants Want You To Drive A Hummer®

plantguy July 19, 2014 August 2, 2014CO2 0

It’s All About The CO2 Sell all your bicycles. Forget about buying a Prius®. Drive the biggest gas-guzzler you can find. Crank up that home and work air conditioning, especially if you get your electricity from coal-fired power plants. Yes, your houseplants – all green (photosynthetic) plants, for that matter…

As Carbon Emissions Reach Record Levels, How Will Increased CO2 Affect Photosynthesis in Plants?

plantguy August 15, 2011 August 17, 2011CO2, Photosynthesis 0

In the past 250 years the amount of atmospheric CO2 has increased by over 40% (from 270 to 387 ppm), due mainly to human activities such as deforestation and the burning of fossil fuels. Carbon dioxide (CO2) emissions are rising faster than the worst-case scenario postulated by the Intergovernmental Panel…

Can Your Garden Benefit From Increasing Atmospheric CO2?

plantguy August 14, 2010 August 14, 2011CO2, Photosynthesis botany, Nature, plants, science 0

YES! Here’s How (And Why): Although “Global Warming” is to some people a controversial subject, the one thing that’s not controversial is that the level of atmospheric CO2 has significantly increased in the past 100 years and will likely continue to increase – at least until humans stop burning fossil…
