FD — Phaseolus vulgaris

Summary

PHAVU_007G246500, designated PvFD on chromosome 7 of French bean (Phaseolus vulgaris), encodes a protein with domains including flavin monoamine oxidase, SWIRM, and amine oxidase, and is annotated with polyamine oxidase, thermospermine oxidase, histone demethylase, and histone deacetylase activities. The gene is associated with polyamine and thermospermine breakdown, epigenetic downregulation of gene expression, post-transcriptional gene silencing, regulation of flowering time and photoperiodism, seed maturation, embryo development, and responses to abscisic acid, salinity, and diterpenes. It is linked to traits including flowering time, seed growth, leaf and stem senescence, root development, brassinosteroid and abscisic acid sensitivity, jasmonic acid content, high and low temperature stress responses, disease tolerance, and salt tolerance. The protein localises to the nucleus, cytoplasm, mitochondria, chloroplast envelope, and Sin3-type and HDAC complexes. Studies of related genes in other species connect the family to flowering time, shoot development, systemic acquired resistance, and ABA response.
