Abstract Receptor-like proteins (RLPs) are cell surface receptors that play important roles in various processes. In several plant species RLPs have been found to play a role in disease resistance, including the tomato Cf and Ve proteins and the apple HcrVf proteins that mediate resistance against the fungal pathogens Cladosporium fulvum, Verticillium spp. and Venturia inaequalis, respectively. The Arabidopsis genome contains 57 AtRLP genes. Two of these, CLV2 (AtRLP10) and TMM (AtRLP17), have well-characterized functions in meristem and stomatal development, respectively, while AtRLP52 is required for defense against powdery mildew. We recently reported the assembly of a genome-wide collection of T-DNA insertion lines for the Arabidopsis AtRLP genes. This collection was functionally analyzed with respect to plant growth, development and sensitivity to various stress responses including pathogen susceptibility. Only few new phenotypes were discovered; while AtRLP41 was found to mediate abscisic acid sensitivity, AtRLP30 (and possibly AtRLP18) was found to be required for full non-host resistance to a bacterial pathogen. Possibly, identification of novel phenotypes is obscured by functional redundancy. Therefore, RNA interference (RNAi) to target the expression of multiple AtRLP genes simultaneously was employed followed by functional analysis of the RNAi lines.
