Isolation and Functional Analysis of EPHEMERAL1-LIKE (EPH1L) Genes Involved in Flower Senescence in Cultivated Japanese Gentians.

ABSTRACT: The elongation of flower longevity increases the commercial value of ornamental plants, and various genes have been identified as influencing flower senescence. Recently, EPHEMERAL1 (EPH1), encoding a NAC-type transcription factor, was identified in Japanese morning glory as a gene that promotes flower senescence. Here we attempted to identify an EPH1 homolog gene from cultivated Japanese gentians and characterized the same with regard to its flower senescence. Two EPH1-LIKE genes (EPH1La and EPH1Lb), considered as alleles, were isolated from a gentian cultivar (Gentiana scabra × G. triflora). Phylogenetic analyses revealed that EPH1L belongs to the NAM subfamily. The transcript levels of EPH1L increased along with its s
