How Corn Became King
July 28, 2015 09:12 AM - Kelly April Tyrrell, University of Wisconsin-Madison

Ten thousand years ago, a golden grain got naked, brought people together and grew to become one of the top agricultural commodities on the planet.

Now, University of Wisconsin-Madison researchers have found that just a single letter change in the genetic script of corn's ancestor, teosinte, helped make it all possible.

Publishing in the journal Genetics this month, UW-Madison genetics Professor John Doebley and a team of researchers describe how, during the domestication of corn, a single nucleotide change in the teosinte glume architectural gene (tga1) stripped away the hard, inedible casing of this wild grass, ultimately exposing the edible golden kernel.

Fort Knox Military Base establishes Indiana Bat Management Area

Mary Jo Harrod, Public Information Officer, Energy and Environment Cabinet, Division of Compliance Assistance, Frankfort, Ky.

Fort Knox, a U.S. military installation located near Louisville, Kentucky, and famous for storing the nation’s gold bullion, has two of the largest known maternity colonies of federally endangered Indiana bats within the range of the species and the largest in Kentucky. On the same night, officials documented 451 and 478 Indiana bats emerging from two separate trees, both are records for this species. The first maternity colony of Indiana bats on Fort Knox (approximately 150 individuals) was discovered in 1999. The total number of Indiana bats in existence has declined due to white-nose syndrome, a devastating wildlife disease; a reduction and contamination of their insect food supply due to pesticide usage and disturbances by humans during the bats’ winter hibernation in caves and mines. During hibernation, bats cluster in groups of up to 500 per square foot, which means a single event can destroy a large number of bats.
