Description
Eiichiro Ono and colleagues traced how dodder weeds, which live off host plants, gained the knack to make sesamin, a plant chemical once tied to sesame. Dodders hold twins of the sesame gene CYP81Q1, and the gene's proteins still make sesamin in lab tests. Gene trees point to a jump from a Lamiales host into an old dodder line.
Dodder attack itself seems to drive the jump, since attack lifts host gene use and gene flow through the sucking root joint. Once in dodder, the gene gained introns step by step, many marked by jumping-gene cuts, while its work stayed intact. Gene jumps through parasites, then intron gain, thus give plants a fresh path to new chemistry.
