From: Natural variation in floral nectar proteins of two Nicotiana attenuata accessions
1D gel electrophoresis of FN proteins from 11 N. attenuata accessions. Black and gray arrows indicate the most variable proteins among 11 different accessions. Several accessions (G2, G6, G7, G10, and Highway) which produced black-arrow indicated proteins (NECTARIN5) had less gray-arrow indicated proteins (NECTARIN1b) than other accessions (Utah, G1, G4, G5, G8, and G9) which had no black-arrow indicated proteins.
