A KNOTTED1-LIKE HOMEOBOX protein regulates abscission in tomato by modulating the auxin pathway.

Plant physiology - 1 Mar 2015

Abstract excerpt

A gene encoding a KNOTTED1-LIKE HOMEOBOX PROTEIN1 (KD1) is highly expressed in both leaf and flower abscission zones. Reducing the abundance of transcripts of this gene in tomato (Solanum lycopersicum) by both virus-induced gene silencing and stable transformation with a silencing construct driven by an abscission-specific promoter resulted in a striking retardation of pedicel and petiole abscission. In contrast,...
