Long-distance signaling in bypass1 mutants: bioassay development reveals the bps signal to be a metabolite.

Molecular plant - 1 Jan 2013

Adhikari Emma, Lee Dong-Keun, Giavalisco Patrick, Sieburth Leslie E

Abstract excerpt

Root-to-shoot signaling is used by plants to coordinate shoot development with the conditions experienced by the roots. A mobile and biologically active compound, the bps signal, is over-produced in roots of an Arabidopsis thaliana mutant called bypass1 (bps1), and might also be a normally produced signaling molecule in wild-type plants. Our goal is to identify the bps signal chemically, which will then allow us...
