“…The remaining 204 R2R3-MYB proteins were unstable (instability index > 40) and they were randomly distributed in each subgroup. This instability of R2R3-MYBs in poplar is similar in other transcription factor families, such as TIFY [ 29 ], ERF [ 30 ], and E2F-DP [ 31 ]. In addition, the grand average of hydropathicity (GRAVY) of all proteins in this family was less than 0, illustrating that these 210 R2R3-MYB proteins might be all hydrophilic proteins.…”

R2R3-type MYB transcription factors are implicated in drought stress, which is a primary factor limiting the growth and development of woody plants. The identification of R2R3-MYB genes in the Populus trichocarpa genome has been previously reported. Nevertheless, the diversity and complexity of the conserved domain of the MYB gene caused inconsistencies in these identification results. There is still a lack of drought-responsive expression patterns and functional studies of R2R3-MYB transcription factors in Populus species. In this study, we identified a total of 210 R2R3-MYB genes in the P. trichocarpa genome, of which 207 genes were unevenly distributed across all 19 chromosomes. These poplar R2R3-MYB genes were phylogenetically divided into 23 subgroups. Collinear analysis demonstrated that the poplar R2R3-MYB genes underwent rapid expansion and that whole-genome duplication events were a dominant factor in the process of rapid gene expansion. Subcellular localization assays indicated that poplar R2R3-MYB TFs mainly played a transcriptional regulatory role in the nucleus. Ten R2R3-MYB genes were cloned from P. deltoides × P. euramericana cv. Nanlin895, and their expression patterns were tissue-specific. A majority of the genes showed similar drought-responsive expression patterns in two out of three tissues. This study provides a valid cue for further functional characterization of drought-responsive R2R3-MYB genes in poplar and provides support for the development of new poplar genotypes with elevated drought tolerance.

“…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.
