“…Maize is a crucial crop worldwide and is widely used as food and livestock feed. During its growth, maize plants show sensitivity to water deficit due to its high water demand, leading to maize yield being greatly affected by drought stress [ 27 – 30 ]. Therefore, it becomes imperative to identify and explore drought tolerance-related genes that can be used to enhance maize resilience through molecular breeding [ 31 – 35 ].…”

Therefore, it becomes imperative to identify and explore drought tolerance-related genes that can be used to enhance maize resilience through molecular breeding [ 31 – 35 ]. In our previous study, we found that ZmPP2C26 regulated drought tolerance [ 36 ] and targeted maize ZmE2F (Zm00001d048412, data not shown), indicating that ZmE2F might be involved in drought response.…”

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.

As one of the most important food and feed crops worldwide, maize suffers much more tremendous damages under heat stress compared to other plants, which seriously inhibits plant growth and reduces productivity. To mitigate the heat-induced damages and adapt to high temperature environment, plants have evolved a series of molecular mechanisms to sense, respond and adapt high temperatures and heat stress. In this review, we summarized recent advances in molecular regulations underlying high temperature sensing, heat stress response and memory in maize, especially focusing on several important pathways and signals in high temperature sensing, and the complex transcriptional regulation of ZmHSFs (Heat Shock Factors) in heat stress response. In addition, we highlighted interactions between ZmHSFs and several epigenetic regulation factors in coordinately regulating heat stress response and memory. Finally, we laid out strategies to systematically elucidate the regulatory network of maize heat stress response, and discussed approaches for breeding future heat-tolerance maize.
