“…MdMYB23 interacts with MdANR promoter, a key regulator of proanthocyanidins biosynthesis, to activate its expression and promote proanthocyanidins accumulation and ROS scavenging [20]. Genes with the same function are MdMYB88 [4], MdMYB10 [21], MdMYB124 [17,[22][23][24], MdMYB108L [25]. MYB repressor can inhibit anthocyanin accumulation.…”

The growth and development of apples are susceptible to environmental stress. The MdMYB gene family is one of the largest gene families in apples. It is widely involved in various resistance signaling pathways in apples and can interact with a variety of genes. Through anthocyanin synthesis, lignin synthesis, epidermal wax synthesis, Na + / H + pump regulation, hormone interaction, etc., the resistance of plants to abiotic and biotic stresses is improved. The MdMYB gene is regulated by multiple factors. It is regulated by epigenetic factors such as methylation and miRNA before transcription. At the transcriptional level, it is regulated by transcription factors such as MdHY5, MdWRKY11 and MdWRKY41. After translation, it is regulated by ubiquitin ligase, which is involved in MdSIZ, MdMEIL and other proteins. This paper reviews the physiological responses and signaling pathways of MdMYB-mediated apple stress resistance and the gene function regulation mechanism of MdMYB, in order to provide new ideas for the study of apple stress resistance.

“…On the other hand, research has identified another microRNA called miR172 as being a positive regulator of cold tolerance [ 107 ]. Additionally, it seems that MdMYB88 also plays a part in regulating microRNA biogenesis through its interaction with MdHYL1 [ 108 ].…”

Apple (Malus 𝗑 domestica) is a popular temperate fruit crop worldwide. However, its growth, productivity, and quality are often adversely affected by abiotic stresses such as drought, extreme temperature, and high salinity. Due to the long juvenile phase and highly heterozygous genome, the conventional breeding approaches for stress-tolerant cultivars are time-consuming and resource-intensive. These issues may be resolved by feasible molecular breeding techniques for apples, such as gene editing and marker-assisted selection. Therefore, it is necessary to acquire a more comprehensive comprehension of the molecular mechanisms underpinning apples' response to abiotic stress. In this review, we summarize the latest research progress in the molecular response of apples to abiotic stressors, including the gene expression regulation, protein modifications, and epigenetic modifications. We also provide updates on new approaches for improving apple abiotic stress tolerance, while discuss current challenges and future perspectives for apple molecular breeding.

“…The regulatory gene-expression network in plants involves several layers of regulatory components that control the biogenesis of genes, including signal transduction, chromatin remodeling, transcription factors, transcription, post-transcription, and translation [ 8 , 9 , 10 , 11 , 12 , 13 ]. MicroRNA (miRNA) is one of the critical components in regulating gene expression at the post-transcriptional level, playing essential roles in various molecular and developmental processes [ 14 ].…”

The application of miRNA mimic technology for silencing mature miRNA began in 2007. This technique originated from the discovery of the INDUCED BY PHOSPHATE STARVATION 1 (IPS1) gene, which was found to be a competitive mimic that prevents the cleavage of the targeted mRNA by miRNA inhibition at the post-transcriptional level. To date, various studies have been conducted to understand the molecular mimic mechanism and to improve the efficiency of this technology. As a result, several mimic tools have been developed: target mimicry (TM), short tandem target mimic (STTM), and molecular sponges (SPs). STTM is the most-developed tool due to its stability and effectiveness in decoying miRNA. This review discusses the application of STTM technology on the loss-of-function studies of miRNA and members from diverse plant species. A modified STTM approach for studying the function of miRNA with spatial–temporal expression under the control of specific promoters is further explored. STTM technology will enhance our understanding of the miRNA activity in plant-tissue-specific development and stress responses for applications in improving plant traits via miRNA regulation.
