Ethylene Biosynthesis-Inducing Xylanase

Abstract: The ethylene biosynthesis-inducing endoxylanase (EIX) from xylan-induced cultures of the fungus, Trichoderma viride, was purified to near homogeneity and compared with the EIX isolated from Cellulysin. Both enzymes migrate as 9.2 kilodalton proteins during gel filtration chromatography under nondenaturing conditions, but the mature polypeptide migrates as a 22 kilodalton band in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The amino acid composition of the 22 kilodalton polypeptide is enriched by… Show more

“…Ethylene-Inducing Xylanase (EIX), a 22-kD protein elicitor (Dean and Anderson, 1991), elicits ethylene biosynthesis, hypersensitive response, and other defense responses in such plants as tomato (Lycopersicon esculentum) and tobacco (Nicotiana tabacum) (Bailey et al, 1992;Felix et al, 1993;Avni et al, 1994;Yano et al, 1998;Elbaz et al, 2002;Ron and Avni, 2004). The increase in ethylene biosynthesis is accompanied by the accumulation of 1-aminocyclopropane-1-carboxylic acid (ACC), an increase in extractable ACC synthase activity, and increases in Acs and ACC oxidase transcripts (Avni et al, 1994).…”

“…It has been known for some time that ACC synthase activity is enhanced in tobacco leaves undergoing a hypersensitive response to pathogen attack (3). An EIX produced by the fungus Trichoderma viride elicits ethylene biosynthesis in N. tabacum cv Xanthi leaf tissue (2). When EIX is applied to the petiole of a detached tobacco leaf, it moves throughout the leaf and, consequently, induces ethylene production and tissue necrosis (1).…”
