Mutant enzyme study aids in understanding of sirtuin’s functions

ITHACA, N.Y. – The enzyme sirtuin 6, or SIRT6, serves many key biological functions in regulating genome stability, DNA repair, metabolism and longevity, but how its multiple enzyme activities relate to its various functions is poorly understood. A team of Cornell University researchers, led by Hening Lin, professor of chemistry and chemical biology, has devised […]

Maize genome ‘dark matter’ discovery a boon for breeders

ITHACA, N.Y. – For astronomers, “dark matter” is the largely hypothetical substance that accounts for approximately 85 percent of the matter in the universe. Now, plant scientists have discovered a different kind of “dark matter” in the maize genome: a tiny percentage of regulatory DNA that accounts for roughly half of the variation in observable […]

Primate evolution in the fast lane: Mechanism discovered that creates ‘clusters of mutations’ that affect traits

The pace of evolution is typically measured in millions of years, as random, individual mutations accumulate over generations, but researchers at Cornell and Bar-Ilan Universities have uncovered a new mechanism for mutation in primates that is rapid, coordinated, and aggressive. The discovery raises questions about the accuracy of using the more typical mutation process as […]

Eating green could be in your genes

ITHACA, N.Y. – Could there be a vegetarian gene? Cornell University researchers have found evidence of a genetic variation – called an allele – that has evolved […]

Surprises discovered in decoded kiwifruit genome

ITHACA, N.Y. – A new study that decoded the DNA sequence of the kiwifruit has concluded that the fruit has many genetic similarities between its 39,040 genes and other plant species, including potatoes and tomatoes. The study also has unveiled two major evolutionary events that occurred millions of years ago in the kiwifruit genome. “The […]
