Salicylic acid mediates the reduced growth of lignin down-regulated plants.

Proceedings of the National Academy of Sciences of the United States of America - 20 Dec 2011

Gallego-Giraldo Lina, Escamilla-Trevino Luis, Jackson Lisa A, Dixon Richard A

Abstract excerpt

Down-regulation of the enzyme hydroxycinnamoyl CoA: shikimate hydroxycinnamoyl transferase (HCT) in thale cress (Arabidopsis thaliana) and alfalfa (Medicago sativa) leads to strongly reduced lignin levels, reduced recalcitrance of cell walls to sugar release, but severe stunting of the plants. Levels of the stress hormone salicylic acid (SA) are inversely proportional to lignin levels and growth in a series of...
