In research published in the March 2010 issue of the journal GENETICS, scientists used tropical maize from Mexico and Thailand to discover chromosome regions responsible for detecting seasonal changes in flowering time. This discovery may lead to higher crop yields, improved disease resistance, and heartier plants able to withstand severe weather.
Weeds often thrive in noncrop areas such as levees, roadsides, and field borders, but they can be suppressed by planting native grasses and treating the area with herbicides, according to an article in the January–March 2010 issue of Invasive Plant Science and Management.
