It’s not a pea, but before Mendel, Josef Kölreuter (“KOL-roy-tur”) hybridized this organism and demonstrated inheritance of both maternal and paternal genes. After protein purification, affinity tags can be cleaved at an E·N·L·Y·F·Q sequence with a protease from a pathogen that infects this organism. Edward East first described quantitative (15[1])trait inheritance after studying corolla length in this organism’s longiflora species. This organism’s N gene upregulates (*) salicylic acid production to resist a pathogen that also infects tomatoes. Muscarine and a compound from this organism name the two types of cholinergic receptors. The first-discovered virus causes a mosaic pattern in this nightshade, whose xylem transports an alkaloid for storage in its leaf vacuoles. For 10 points, name this plant that defends against herbivory using nicotine. ■END■
