Basic information
Locus name	AT1G11190
Alias	BFN1
Organism	Arabidopsis thaliana
Taxonomic identifier	[NCBI]
Function category	Nucleic acid degradation:RNA and DNA degradation
Effect for Senescence	Unclear
Gene Description	Encodes a bifunctional nuclease that acts on both RNA and DNA involved in nucleic acid degradation to facilitate nucleotide and phosphate recovery during senescence. It has mismatch-specific endonuclease activity with wide recognition of single base mismatches as well as the ability to cleave indel types of mismatches (heteroduplexes with loops).
Evidence	Molecular evidence:Northern and GUS staining [Ref 1, Ref 2]; Genomic evidence: microarray data [Ref 3, Ref 4]
