Early breeding reduced harmful mutations in sorghum
A new Cornell University study found that harmful mutations in sorghum landraces – early domesticated crops – decreased compared to their wild relatives through the course of domestication and breeding.
Researchers identify most powerful gene variant for height known to date
• Newly discovered gene variant in Peruvian populations is powerfully linked with height
• Five percent of Peruvians carry the variant, which originates exclusively from Native American populations
• The variant occurs on a gene that, when mutated, causes Marfan syndrome, a condition marked by connective tissue abnormalities, including serious cardiovascular problems
• The newly discovered variant is not associated with disease and may confer adaptive evolutionary advantage to populations that carry it
