Summary
Challenging tomato or tobacco varieties with ethylene-
inducing xylanase (EIX) from the fungus Trichoderma
viride causes rapid induction of plant defence responses
leading to programmed cell death. Using the yeast two-
hybrid system, we isolated a novel protein, tomato small
ubiquitin-related modiŽer protein (T-SUMO), which
speciŽcally interacts with EIX. T-SUMO, a cytoplasmic
protein, is a member of the ubiquitin-like protein family.
It shows homology to human protein sentrin/SUMO1,
which suppresses tumour necrosis factor-induced cell
death. Transgenic plants that express T-SUMO in the
sense orientation suppress EIX induction of ethylene
biosynthesis and cell death, while in the antisense
