^aProtein numbers exclude predicted alternative-splicing products. The total number of proteins in the A. thaliana genome is 32,690 including all predicted products. Numbers in square brackets include predicted alternative-splice products.

^bNumbers in parentheses are those positively identified from the 22 known A. thaliana 7TMR proteins. * indicates that GTG1 and GTG2 are also identified.
