The Colors are Changing and WCU's Expert is Here if You're Wondering What to Expect

Every autumn one thing is for certain. The temps will get cooler, kids are back in school and the leaves are about to burst into a bouquet of reds, oranges, yellows, browns and more. It's the time of year that draws nature lovers and those who just appreciate a change of scenery to go out, explore and enjoy everything nature has to offer at this time of year. It's also a topic that garners serious media attention too. And when reporters are curious they're connecting with experts like Western Carolina University's Darby Harris for insight and perspective about when the colors are set to change and where we can expect to take in the dbest displays of color. A local expert is chiming in on what the leaves might look like this year. A Western Carolina University biology expert says it takes several factors to make a colorful leaf season including temperature, wetness and daylight. The ingredients for fall color are the same every year, but aside from the predictable loss of daylight, the weather quantities are variable. “I'd like to say with great optimism that we're on track for what I'd call a good fall season,” said WCU biology instructor Darby Harris. He says our mountains could use some rain. “Severe drought could be a problem, but we're not there yet,” he said. Harris says sunny days and cooler weather in the mid-40 or upper-30 degrees are needed, too. “Cooler nights are really what would be helpful for peak color production,” he said. Dabs of yellows and oranges dot the landscape around the Blue Ridge Parkway as photosynthesis is underway. That brisk temperature can also add to the palette.

“Mountains, little traffic, WCU is perfect!”
This was the reaction that Darby Harris had the first time he visited Western Carolina University his senior year in high school. He knew that choosing the right college for him meant choosing the right place to cycle. It was in this moment during our interview that I realized just how much cycling had impacted his life and major life decisions.

Plants and plant products useful for biofuel manufacture and feedstock, and methods of producing same

US8383888B1

2013

A method of processing plant cellulose includes providing plant cellulose that is from a plant expressing a CESA polypeptide variant having at least one amino acid mutation in its carboxy-terminal transmembrane region; and saccharifying the plant cellulose to produce fermentable sugars. The method can also include fermenting the fermentable sugars to produce alcohol. A method of producing a plant having beneficial saccharification properties includes introducing into a plant a polynucleotide encoding a CESA polypeptide variant having at least one amino acid mutation in its carboxy-terminal transmembrane region; and expressing in the plant the CESA polypeptide variant, wherein plant cellulose of the plant expressing the CESA polypeptide variant has beneficial saccharification properties as compared to a wild-type plant.

The Use of Small Molecules to Dissect Cell Wall Biosynthesis and Manipulate the Cortical Cytoskeleton

Plant Chemical Biology - Chapter 5.1

2014

Plant cell walls are composed of highly glycosylated proteins and polysaccharides, including pectin, hemicelluloses, and cellulose, which form a complex and dynamic extracellular matrix that modulates cell expansion. The primary cell wall polysaccharide is cellulose, and it stands as the most abundant biopolymer in the world. Although genetic screens have identified a handful of genes that participate in cellulose biosynthesis, the complexity of events contributing to activation of the CesA at the plasma membrane, its motility and interaction with other polymers and proteins suggest that the list of players is far from complete. This chapter examines the use of chemical genetics to dissect and extend our understanding of cellulose biosynthesis in plants.

The Synthesis, Regulation and Modification of Lignocellulosic Biomass as a Resource for Biofuels and Bioproducts

Advanced Biofuels and Bioproducts

2013

Most of the plant biomass is cell wall and therefore represents a renewable carbon source that could be exploited by humans for bioenergy and bioproducts. A thorough understanding of the type of cell wall being harvested and the molecules available will be crucial in developing the most efficient conversion processes. Herein, we review the structure, function, and biosynthesis of lignocellulosic biomass, paying particular attention to the most important bioresources present in the plant cell wall: cellulose, hemicellulose, and lignin. We also provide an update on key improvements being made to lignocellulosic biomass with respect to utilization as a second-generation biofuel and as a resource for bioproducts.
