Amino acid sequence and toxicity of the alpha elicitin secreted with ubiquitin by Phytophthora infestans

Mol Plant Microbe Interact. 1994 Mar-Apr;7(2):302-4. doi: 10.1094/mpmi-7-0302.

Abstract

A single alpha elicitin, phytotoxin secreted by Phytophthora infestans, responsible for systemic HR-like necroses in tobacco, was purified from the culture filtrate. Its sequence was compared to other alpha elicitins in correlation with toxicity. In the filtrate, we also found ubiquitin, whose biological function remains unclear.
