III. In Vivo Effect of Ethylene on Hydroxyproline-Rich Glycoprotein Accumulation in the Cell Wall of Diseased Plants

Université Paul Sabatier, Centre de Physiologie Végétale—L. A. 241 Centre National de la Recherche Scientifique, 31062 Toulouse Cédex, France

Ethylene production and cell wall hydroxyproline-rich glycoprotein (HRGP) biosynthesis are greatly enhanced in melon (Cucumin melo cv. Cantaloup charentais) seedlings infected with Colletotrichum lagenarium. Short-term experiments performed in the presence of specific inhibitors of the ethylene pathway from methionine, namely L-canaline and amino-ethoxyvinylglycine, indicate that under non-toxic conditions, both ethylene and [¹⁴C]hydroxyproline deposition in the cell wall of infected tissues are significantly lowered. On the contrary, treatment of healthy tissues with 1-aminocyclopropane 1-carboxylic acid, a natural precursor of ethylene, stimulates both the production of the hormone and the incorporation of [¹⁴C]hydroxyproline into cell wall proteins.

The data provide the first evidence of the in vivo effect of ethylene on the cell wall hydroxyproline-rich glycoprotein biosynthesis in plants.
