Impacts of T-Phylloplanin Gene Knockdown and of Helianthus and Datura Phylloplanins on Peronospora tabacina Spore Germination and Disease Potential1[OA] From: Plant Physiology | Date: August 1, 2007| Author: Shepherd, Ryan W; Wagner, George J; Kroumova, Antoaneta B | Copyright American Society of Plant Physiologists Aug 2007.

T-phylloplanin proteins secreted to aerial surfaces of tobacco (Nicotiana tabacum) by short procumbent trichomes inhibit spore germination and blue mold disease caused by the oomycete pathogen Peronospora tabacina. Many other plants were found to contain water-washed leaf surface proteins (phylloplanins), but the functions and properties of these are not known. Here we extend earlier evidence for the antifungal activity of T-phylloplanins using a reverse genetics approach. RNA interference of...
