Abstract Background The Arabidopsis thaliana CONSTITUTIVE EXPRESSOR OF PATHOGENESIS-RELATED GENES5 CPR5 gene has been previously implicated in disease resistance cell proliferation cell death and sugar sensing and encodes a putative membrane protein of unknown biochemical function. Trichome development is also affected in cpr5 plants which have leaf trichomes that are reduced in size and branch number. Results In the work presented here the role of CPR5 in trichome development was examined. Trichomes on cpr5 mutants had reduced birefringence suggesting a difference in cell wall structure between cpr5 and wild-type trichomes. Consistent with this leaf cell walls of cpr5 plants contained significantly less paracrystalline .
