“…The CO gene is involved in regulating flowering under long days, and its repression by CDF1 represses flowering in Arabidopsis [ 44 , 73 ]. Its ortholog in B. napus , BnCDF1 ( BnaDof54 in our study), was also reported to play a role in flowering [ 74 ]. BnaDof54 , functionally annotated to be involved in flower development, shows very high expression in flowers.…”

DNA binding with one finger (DOF) proteins are plant-specific transcription factors that play roles in diverse plant functions. However, little is known about the DOF protein repertoire of the allopolyploid crop, Brassica napus. This in silico study identified 117 Brassica napus Dof genes (BnaDofs) and classified them into nine groups (A, B1, B2, C1, C2.1, C2.2, C3, D1, and D2), based on phylogenetic analysis. Most members belonging to a particular group displayed conserved gene structural organisation and protein motif distribution. Evolutionary analysis exemplified that the divergence of the Brassica genus from Arabidopsis, the whole-genome triplication event, and the hybridisation of Brassica oleracea and Brassica rapa to form B. napus, followed by gene loss and rearrangements, led to the expansion and divergence of the Dof transcription factor (TF) gene family in B. napus. So far, this is the largest number of Dof genes reported in a single eudicot species. Functional annotation of BnaDof proteins, cis-element analysis of their promoters, and transcriptomic analysis suggested potential roles in organ development, the transition from the vegetative to the reproductive stage, light responsiveness, phytohormone responsiveness, as well as potential regulatory roles in abiotic stress. Overall, our results provide a comprehensive understanding of the molecular structure, evolution, and possible functional roles of Dof genes in plant development and abiotic stress response.

“…PpDof1 serves as transcriptional repressor and is involved in the growth of nutrient-dependent filament in Physcomitrella patens [24]. BnCDF1 , a member of Dof family TF, takes part in regulating the flowering time and freezing tolerance in Brassica napus [25]. Overexpression of PpDof5 gene from maritime pine in transgenic Arabidopsis enhances the content of lignin [26].…”

Tea plant (Camellia sinensis (L.) O. Kuntze) is affected by abiotic stress during its growth and development. DNA-binding with one finger (Dof) transcription factors (TFs) play important roles in abiotic stress tolerance of plants. In this study, a total of 29 putative Dof TFs were identified based on transcriptome of tea plant, and the conserved domains and common motifs of these CsDof TFs were predicted and analyzed. The 29 CsDof proteins were divided into 7 groups (A, B1, B2, C1, C2.1, C2.2, and D2), and the interaction networks of Dof proteins in C. sinensis were established according to the data in Arabidopsis. Gene expression was analyzed in “Yingshuang” and “Huangjinya” under four experimental stresses by qRT-PCR. CsDof genes were expressed differentially and related to different abiotic stress conditions. In total, our results might suggest that there is a potential relationship between CsDof factors and tea plant stress resistance.

“…Overexpressing SlCDF1 or SlCDF3 in Arabidopsis showed increased drought and salt tolerance 41 . In Brassica, the BnCDF1 gene was induced in response to low temperatures, and overexpressing BnCDF1 in Arabidopsis could increase freezing tolerance 42 . In watermelon, nine selected Dof genes showed differential expression under salt stress and ABA treatments 43 .…”

“…Therefore, we postulate that SoDof22, SoDof3 and SoDof15 have an important role in responding to heat, cold and drought stresses. Notably, overexpressing BnCDF1 in Arabidopsis also delays owering time by reducing the expression of CO and FT 42 . Interestingly, SoDof22 contains high expression level both in in orescence and under cold stress, suggesting that the role of SoDof22 might be similar to BnCDF1 within the interplay between environmental conditions and owering time.…”

DNA-binding with one finger (Dof) transcription factors are plant-specific transcription factors involved in numerous pathways of plant development, especially in respond to abiotic stresses. Although genome-wide analysis of this gene family has been performed in many species, Dof genes in spinach have not been thoroughly analyzed. We performed a genome-wide analysis and characterization of Dof gene family in spinach. Twenty two Dof genes were identified and classified into four groups with nine subgroups, which was further corroborated by gene structure and motif analyses. Ka/Ks analysis revealed that SoDofs were subjected to purify selection. Using Cis-acting elements analysis, SoDofs were involved in plant growth and development, plant hormones and stress responses. Expression profiling demonstrated that SoDofs expressed in leaf and inflorescence, and responded to cold, heat, and drought stresses. SoDof22 expressed the highest level in male flowers and under cold stress. These results provided a genome-wide analysis of SoDof genes, their gender- and tissue-specific expression, and response to abiotic stresses. The knowledge and resources gained from these analyses will benefit spinach improvement.
