In this study, members of the BvDof transcription factor family were identified in the beet genome data (Beta vulgaris L.) Through systematic analysis, 22 BvDof family genes were found in the beet genome, and they were divided into nine groups by phylogenetic analysis. Fifteen members of the BvERF family were involved in the transition to rapid root tuber growth. There was a tandem replication during the generation of the Dof gene family in sugar beet. Bv1_zfms, Bv_ofna, Bv5_racn, and Bv6_augo may be involved in the regulation of secondary cambium development in the beet root tuber. Bv9_nood, Bv1_zfms, and Bv6_cdca may be related to the growth rate of root tubers. The results provide a reference for further elucidating the molecular mechanism of the BvDof transcription factor, which regulates the development of beet root tubers.
在本研究中，通过在甜菜基因组数据（Beta vulgaris L.）中进行系统分析，鉴定出了BvDof转录因子家族的成员。在甜菜基因组中发现了22个BvDof家族基因，并通过系统发育分析将它们分为9组。15个BvERF家族成员参与了向快速块根生长的转变。甜菜Dof基因家族在产生过程中存在串联重复。Bv1_zfms、Bv_ofna、Bv5_racn和Bv6_augo可能参与甜菜块根次生形成层发育的调控。Bv9_nood、Bv1_zfms和Bv6_cdca可能与块根的生长速率有关。这些结果为进一步阐明调控甜菜块根发育的BvDof转录因子的分子机制提供了参考。
