“…In eukaryotes, the ZmE2F family is characterized as a TF that plays crucial roles in cell division, DNA repair, and differentiation [ 11 , 13 – 16 ]. However, the E2F family is only genome-wide identified in a few plants, including Arabidopsis , rice, wheat, Moso bamboo, Medicago truncatula , and Phaseolus vulgaris [ 9 , 24 – 26 ]. In the present study, 21 ZmE2F members were identified in the maize genome (Table 1 ) and classified into E2F, DP, and DEL subclades (Fig.…”

“…To date, the function of E2F in regulating plant stress tolerance remains unknown, although few reports have shown that the expression of some E2F genes is responsive to stress [ 9 , 24 – 26 ]. In our study, abundant stress-responsive acting elements were found in ZmE2F promoter regions, such as ABREs and MBSs, suggesting the response of ZmE2Fs to stress and the potential roles of ZmE2Fs .…”

“…Furthermore, AtE2Fa acts downstream of ERECTA kinase, which is involved in cell size and stomatal density [ 23 ]. Via expression analysis, it is suggested that TaE2F-DP of wheat, PheE2F/DPs of Moso bamboo, E2F/DP genes of Medicago truncatula , and PvE2F/DPs of Phaseolus vulgaris respond to drought or salt stress, suggesting their potential roles in regulating stress tolerance [ 9 , 24 – 26 ]. To date, however, the role of E2F in plant stress tolerance remains obscure.…”

Background The early 2 factor (E2F) family is characterized as a kind of transcription factor that plays an important role in cell division, DNA damage repair, and cell size regulation. However, its stress response has not been well revealed. Results In this study, ZmE2F members were comprehensively identified in the maize genome, and 21 ZmE2F genes were identified, including eight E2F subclade members, seven DEL subfamily genes, and six DP genes. All ZmE2F proteins possessed the DNA-binding domain (DBD) characterized by conserved motif 1 with the RRIYD sequence. The ZmE2F genes were unevenly distributed on eight maize chromosomes, showed diversity in gene structure, expanded by gene duplication, and contained abundant stress-responsive elements in their promoter regions. Subsequently, the ZmE2F6 gene was cloned and functionally verified in drought response. The results showed that the ZmE2F6 protein interacted with ZmPP2C26, localized in the nucleus, and responded to drought treatment. The overexpression of ZmE2F6 enhanced drought tolerance in transgenic Arabidopsis with longer root length, higher survival rate, and biomass by upregulating stress-related gene transcription. Conclusions This study provides novel insights into a greater understanding and functional study of the E2F family in the stress response.
