Abstract
Described is a method of screening libraries of variant proteins produced in plant leaves using a plant viral vector to identify a gene of interest comprising, inoculating leaves with a library of viruses expressing variant genes, allowing time for infected foci to form, harvesting a leaf, sticking one face of the leaf to a sticky support material to immobilize the leaf and leaving the opposing face of the leaf exposed, abrading the exposed face with granular material, placing the abraded face in contact with a blot membrane having a backing comprising blotting paper, placing the assembly into a vacuum seal bag; evacuating and sealing the bag; removing the assembly and separating the membrane, performing an assay on the membrane to identify an infected focus of interest; recovering virus corresponding to the infected focus; recovering nucleic acid from the virus, and identifying the gene of interest from the nucleic acid.
