The DOF family transcription factors, which involved in biotic stress, has not been studied in responding to strawberry crown rot. In this study, the<em> DOFs</em> of <em>Fragaria × ananassa, F. iinumae</em>, <em>F. nilgerrensis</em>,<em> F. viridis</em>, and<em> F. vesca </em>were characterized. One hundred and eighteen <em>FaDOFs</em>, twenty-two <em>FiDOFs</em>, twenty-three <em>FnDOFs</em>, twenty-five <em>FviDOFs</em> and thirty-seven <em>FvDOFs</em> were identified. Gene cluster analysis showed nearly seventy segmental duplication and seventeen tandem duplications for <em>DOF</em> family expansion in octaploid strawberry. In addition, <em>59 FaDOFs</em> showed syntenic relationships with 32 <em>AtDOFs</em>, which were located on all <em>F.×ananassa</em> chromosomes except Fvb4-1 and Fvb4-2. Except for five <em>DOFs</em> of diploid strawberries had syntenic relationships to one <em>FaDOF</em>, most of them corresponded to multiple <em>FaDOF</em>s. Gene expression analysis revealed that 107 <em>FaDOFs</em> were expressed in crown, and most of them were downregulated by crown rot, while some <em>FaDOFs</em> such as <em>FaDOF107</em>,<em> 12, 82, 91, 90</em> and <em>101</em> were upregulated, whose regulation was not always consistent with the <em>cis</em>-elements in their promoters<em>.</em> Together, these results provided a basis for further functional studies of the <em>FaDOFs</em>.</p>}, number={1}, journal={Notulae Botanicae Horti Agrobotanici Cluj-Napoca}, author={LUO, Chun and HU, Yuyang and SHU, Bo}, year={2022}, month={Mar.}, pages={12640} }
