Comment The over expression of 35S::Rcn1 in rice resulted in severe phenotypes with substantial delays to never heading plants. A few plants with moderate phenotypes displayed 13-50 day delay in heading. The delay in days to heading is related to suppression of processes involved in transition of shoot apical meristem from vegentative to reproductive stage. Transgenic rice plants with moderate phenotypes displayed increased number of leaves when evlaluated in short-day and long-day conditions and altered inflorescence (panicle) morphology. An increased number of primary and secondary branches in the transgenic plant inflorescence, resulted in increased number of florets by three times. Rcn2 gene was isolated from a cDNA screen using the EST clone (genbank accession D24998). The ectopic expression of Rcn1 (35S::Rcn1) in Arabidopsis transgenic line exhibited a phenotype of late-flowering, highly branched inflorescence and flowers with shoot like sharacteristics, similar to that reported for 35S::TFL1. The gene belongs to the Phosphatidylethanolamine-binding protein family. It bears strong similarity to Antirrhinum CEN (CENTRORADIALIS) as compared to Arabidopsis TFL1. Both CEN and TFL1 are known Phosphatidylethanolamine-binding proteins and play a role in delaying phase transition of shoot apical meristem from vegetative to reproductive phase.
