Jasmonic Acid Levels Are Reduced in COMATOSE ATP-Binding Cassette Transporter Mutants. Implications for Transport of Jasmonate Precursors into Peroxisomes

Abstract

We provide evidence that the peroxisomal ATP-binding cassette (ABC) transporter COMATOSE (CTS) is involved in the biosynthesis of jasmonic acid (JA) in Arabidopsis ( Arabidopsis thaliana ) leaves. Basal JA levels were greatly reduced but not completely abolished in two cts mutant alleles, and JA
