Tryptophan deficiency affects organ growth by retarding cell expansion in Arabidopsis.

Abstract

Tryptophan (Trp) is an essential amino acid required not only for protein synthesis but also for the production of many plant metabolites, including the hormone auxin. Mutations that disrupt Trp biosynthesis result in various developmental defects in plant organs, but how Trp affects organ growth and development remains unclear. Here, we identify an… (More)
