Each of us have the entire blueprint for our bodies contained in every cell, and the same is true of plants. This information is stored in the form of an extremely long molecule known as DNA (in human cells its length is ~6 feet). Studying and understanding DNA in plants has led to many advances in weed science including; the development of herbicide- tolerant crop varieties, understanding the causes of herbicide resistance and understanding the origins and spread of weeds in our environment.
Here in California, the weed science group at UC Davis is utilizing this technology to investigate glyphosate resistance that has been detected in California populations of junglerice. Junglerice is a summer grass weed present in many...

This is the abstract and a poster from a presentation that I made at the 2016 Weed Science Society of America meeting in San Juan, PR. The results were generated from one run of each of the experiments. At this time, all of the studies have been replicated, the data is being analyzed and the manuscripts are in preparation.
JUNGLERICE (ECHINOCHLOA COLONA) GROWTH AND DEVELOPMENT IN RESPONSE TO TEMPERATURE AND SHADE.
This article was originally prepared for the CWSS Research Update and News (September 2014 edition). You can see it and several other articles at the CWSS website. You can also get information on the annual California Weed Science Society Conference which will be held in Santa Barbara January 21-25, 2015.

The risks of GMO herbicide-resistant crops as a source for resistance traits in weeds has garnered recent attention in discussions of so-called “superweeds”. [I've commented previously on my general disagreement with the term "superweed" when talking about herbicide resistance]. Some media reports and online sources have suggested that herbicide resistance can be caused by resistance “jumping” from the crops into weeds. In fact, at least one online dictionary defines the problem in these terms:

Managing Junglerice in Corn
by Steve Wright and Carol Frate
Introduction. The summer annual grass weed junglerice (Echinocloa colona) has become a difficult problem to control in corn fields in the southern San Joaquin Valley, especially minimum till...
