Corn researchers discover novel gene shut-off mechanisms
Date:10/31/2008

functions to repress repetitive sequences, including mobile DNA elements called transposons," Meyers said. "Thus, small interfering RNAs act to protect the genome," he noted.

"Corn contains an extra layer of protective small RNAs that had not been observed in Arabidopsis, so there must be additional genes other than MOP1 that produce this," Meyers said.

The scientific community is sequencing the corn genome now, Meyers said. Once the genome is available, the work of matching up small RNAs to specific traits in corn will be much easier, he noted.

"This research is helping us to better understand the biology of corn--one of the most important plants in the world--and gives us new avenues for exploring a novel class of small RNAs," Meyers said.
