has revealed that honeybees do not have as many genes for taste receptors as other animals of a similar size, such as flies and mosquitoes. This prompted scientists to think that perhaps honeybees had a reduced need to detect and learn about toxins,...
All roads lead to GUN1
...neer in Hyderabad, India, searched the Arabidopsis genome

Mitochondrial genes move to the nucleus -- but it's not for the sex
