The University of Nebraska–Lincoln's Department of Agronomy and Horticulture will begin its fall seminar series with “Pollen-mediated Gene Flow and Transfer of Herbicide Resistance Alleles,” presented by Amit Jhala, associate department head and professor of agronomy and horticulture, on Thursday, Sept. 12. Jhala will discuss how herbicide-resistant weeds spread through pollen-mediated gene flow and explain how different weed species have varying potentials for this gene transfer.
“Managing herbicide-resistant weeds is a challenge for growers,” Jhala said. “Once herbicide-resistant weeds evolve, it can be spread by pollen, known as pollen-mediated gene flow. Reproductive biology differs markedly among weed species, as does the potential for gene flow.”
During the seminar, Jhala will present examples of economically significant weeds, such as waterhemp, Palmer amaranth, and giant ragweed, alongside crops like corn and popcorn. These examples will help illustrate how pollen-mediated gene flow impacts the transfer of herbicide resistance alleles in agricultural settings.
The seminar series will continue each Thursday in Keim Hall, Room 150, at 11 a.m. CST/CDT. All seminars are free and open to the public, with live streaming and recorded options available unless otherwise noted. Refreshments will be served at 10:30 a.m.
Upcoming topics in the series include agricultural collaborations, genetic research in crops, sustainable farming practices, and conservation efforts. Speakers include experts from the University of Nebraska–Lincoln and guest speakers from institutions such as Auburn University and Corteva Agriscience.
For those interested in attending, the series offers an opportunity to learn about the latest advancements in agriculture, environmental science, and sustainable farming practices.
