Repressed by silencing mediated by polycomb group (PcG) protein complex containing EMF1 and EMF2. Belongs to the disease resistance NB-LRR family. RPP8/HRT subfamily. Could be the product of a pseudogene. In strain cv. Columbia, a stop codon at position 117 and a naturally occurring frameshift at position 846 result in a truncated LOV1 protein. A complete sequence for LOV1 can be found in strain cv. Cl-0 (AC A7XGN8). Functional and comparative genomics of disease resistance gene homologs
