Florida State University biologists led by Hank Bass developed a new
approach of chromatin profiling. This was developed through studying the
chromatin structure present in 12 different sample tissues of maize and
mapping this chromatin.
Their findings show that exposure of the different maize genome samples in
an enzyme has led to the discovery of hypersensitive regions in the DNA. The
regions were also found to be associated with gene regulation. Through these
observed findings, they were able to reveal biochemical signatures of DNA.
These were then compared to other organisms through the use of infrared
goggles in a dark forest.
"We have found new ways to see really important parts of the chromatin,"
This profiling technique is also applicable to other plants and mammals.
