“…These genes have also been studies in other plant species. For example, heterologous expression of the cotton ( Gossypium hirsutum ) ERF gene GhB301 in Nicotiana benthamiana enhanced its resistance against fusarium wilt [ 8 ]. The basic helix–loop–helix (bHLH) superfamily is considered as the second largest class of plant transcription factors [ 9 ].…”

“…Thus far, our understanding of the defense molecular mechanisms of powdery mildew is limited. In grapevine, the expression of the VqSTS6 gene from Vitis quinquangularis enhanced powdery mildew resistance by increasing the content of stilbenes [ 8 ]. The ectopic expression of VvDOF3 in Arabidopsis conferred enhanced resistance to powdery mildew through the SA signaling pathway [ 26 ].…”

APETALA2/ETHYLENE RESPONSIVE FACTOR (AP2/ERF) transcription factors play important roles in plant development and stress response. Although AP2/ERF genes have been extensively investigated in model plants such as Arabidopsis thaliana, little is known about their role in biotic stress response in perennial fruit tree crops such as apple (Malus × domestica). Here, we investigated the role of MdERF100 in powdery mildew resistance in apple. MdERF100 localized to the nucleus but showed no transcriptional activation activity. The heterologous expression of MdERF100 in Arabidopsis not only enhanced powdery mildew resistance but also increased reactive oxygen species (ROS) accumulation and cell death. Furthermore, MdERF100-overexpressing Arabidopsis plants exhibited differential expressions of genes involved in jasmonic acid (JA) and salicylic acid (SA) signaling when infected with the powdery mildew pathogen. Additionally, yeast two-hybrid and bimolecular fluorescence complementation assays confirmed that MdERF100 physically interacts with the basic helix–loop–helix (bHLH) protein MdbHLH92. These results suggest that MdERF100 mediates powdery mildew resistance by regulating the JA and SA signaling pathways, and MdbHLH92 is involved in plant defense against powdery mildew. Overall, this study enhances our understanding of the role of MdERF genes in disease resistance, and provides novel insights into the molecular mechanisms of powdery mildew resistance in apple.

“…The application of plant growth regulators is an effective approach for improving the Fe de ciency tolerance of crops (Akhtar et al 2018;Kong et al 2014). Res is a phytoalexin that contributes to plant biotic responses (Liu et al 2019;Schulze et al 2005). Exogenous application of Res reduces postharvest decay in several fruit types, such as tomatoes, grapes, and avocado pears (Jimenez et al 2005).…”

Resveratrol (Res), a phytoalexin, has been widely reported to participate in plant resistance to fungal infections. However, little information is available on its role in abiotic stress, especially in iron deficiency stress. Malus baccata is widely used as apple rootstock in China, but it is sensitive to iron deficiency. In this study, we investigated the role of exogenous Res in M. baccata seedings under iron deficiency stress. Results showed that applying 100 µmol exogenous Res could alleviate iron deficiency stress. The seedlings treated with Res had a lower etiolation rate and higher chlorophyll content and photosynthetic rate compared with the apple seedlings without Res treatment. Exogenous Res increased the iron content in the roots and leaves by inducing the expression of MbAHA genes and improving the H+-ATPase activity. As a result, the rhizosphere pH decreased, iron solubility increased, the expression of MbFRO2 and MbIRT1 was induced, and the ferric-chelated reductase activity was enhanced to absorb large amounts of Fe2+ into the root cells under iron deficiency conditions. Moreover, exogenous Res application increased the contents of IAA, ABA, and GA3 and decreased the contents of DHZR and BL for responding to iron deficiency stress indirectly. In addition, Res functioned as an antioxidant that strengthened the activities of antioxidant enzymes and thus eliminated reactive oxygen species production induced by iron deficiency stress. These findings are expected to enhance the application and examination of the physiological role of Res under iron deficiency stress in apples.

MYB Genes Involved in Domestication and Crop Improvement

Domestication of the world's crop species has been achieved through improvements in yield, and product qualities, with or without the guidance of scientific knowledge. These selection pressures are applied by breeders (and before them, farmers) both intentionally and unintentionally to improve crop features, which have often been grouped into ‘production traits’ and ‘quality traits’. New approaches to breeding that incorporate genome sequencing, mapping, and identification of genes underlying traits have revealed new variants in the family of transcription factors (TFs) called MYBs as driving important features in both these categories of domestication traits. In this article, we review the progress in understanding the role of MYB TFs in crop performance, as well as reasons to predict further gains in yield and quality centred on the MYB TF family.
