Título: | The four FAD-dependent histone demethylases of Arabidopsis are differently involved in the control of flowering time |
Autor: | Martignago, Damiano CSIC ORCID; Bernardini, Benedetta; Polticelli, Fabio; Salvi, Daniele; Cona, Alessandra; Angelini, Riccardo; Tavladoraki, Paraskevi | Fecha de publicación: | 2019 | Editor: | Frontiers Media | Citación: | Frontiers in Plant Science 10: 669 (2019) | Resumen: | In Arabidopsis thaliana, four FAD-dependent lysine-specific histone demethylases (LDL1, LDL2, LDL3, and FLD) are present, bearing both a SWIRM and an amine oxidase domain. In this study, a comparative analysis of gene structure, evolutionary relationships, tissue- and organ-specific expression patterns, physiological roles and target genes for the four Arabidopsis LDL/FLDs is reported. Phylogenetic analysis evidences a different evolutionary history for the four LDL/FLDs, while promoter activity data show that LDL/FLDs are strongly expressed during plant development and embryogenesis, with some gene-specific expression patterns. Furthermore, phenotypical analysis of loss-of-function mutants indicates a role of all four Arabidopsis LDL/FLD genes in the control of flowering time, though for some of them with opposing effects. This study contributes toward a better understanding of the LDL/FLD physiological roles and may provide biotechnological strategies for crop improvement. | Versión del editor: | https://doi.org/10.3389/fpls.2019.00669 | URI: | http://hdl.handle.net/10261/207254 | DOI: | 10.3389/fpls.2019.00669 | E-ISSN: | 1664-462X |
