Has Phenotype yes
Description OsFOR1 gene was cloned from immature panicles of rice, the protein contains a leucine-rich repeat (LRR) domain. The exression level of OsFOR1 is increased as the panicles matured, mostly detected in young spikelet primordia and all of the young floral organs (lodicule, stamen and carpel). Antisense OsFOR1 plants show servere phenotypes by producing extra numbers of floral organs in spikelets. OsFOR1 is similar to those polygalacturonase-inhibiting proteins (PGIP) from other plant species based on structure and number of LRRs. Recombinant OsFOR1 protein shows PGIP activity against the Aspergillus niger polygalacturonase.
