“…These include bZIP, MYB, NAC, and TCP TFs. According to previous studies, Chrysanthemum CmbZIP1 is mainly expressed in apical and axillary buds, and the number of branches in transgenic Arabidopsis overexpressing CmbZIP1 is decreased compared with that of the wild type [ 52 ]. In addition, ELONGATED HYPOCOTYL 5 of the bZIP TF family in Arabidopsis can significantly increase the number of branches [ 53 ].…”

Background Branching is a plastic character that affects plant architecture and spatial structure. The trait is controlled by a variety of plant hormones through coordination with environmental signals. Plant AT-rich sequence and zinc-binding protein (PLATZ) is a transcription factor that plays an important role in plant growth and development. However, systematic research on the role of the PLATZ family in apple branching has not been conducted previously. Results In this study, a total of 17 PLATZ genes were identified and characterized from the apple genome. The 83 PLATZ proteins from apple, tomato, Arabidopsis, rice, and maize were classified into three groups based on the topological structure of the phylogenetic tree. The phylogenetic relationships, conserved motifs, gene structure, regulatory cis-acting elements, and microRNAs of the MdPLATZ family members were predicted. Expression analysis revealed that MdPLATZ genes exhibited distinct expression patterns in different tissues. The expression patterns of the MdPLATZ genes were systematically investigated in response to treatments that impact apple branching [thidazuron (TDZ) and decapitation]. The expression of MdPLATZ1, 6, 7, 8, 9, 15, and 16 was regulated during axillary bud outgrowth based on RNA-sequencing data obtained from apple axillary buds treated by decapitation or exogenous TDZ application. Quantitative real-time PCR analysis showed that MdPLATZ6 was strongly downregulated in response to the TDZ and decapitation treatments, however, MdPLATZ15 was significantly upregulated in response to TDZ, but exhibited little response to decapitation. Furthermore, the co-expression network showed that PLATZ might be involved in shoot branching by regulating branching-related genes or mediating cytokinin or auxin pathway. Conclusion The results provide valuable information for further functional investigation of MdPLATZ genes in the control of axillary bud outgrowth in apple.

“…A recent study in cotton (Gossypium hirsutum) has shown that GhHY5 is induced by light in shoots, and it gets transported to the root by the phloem, where it activates its own expression in the root. The GhHY5 in the root promotes nitrogen uptake of the root by inducing the expression of GhNRT1.1 (Wang et al, 2023). These reports have highlighted the crucial involvement of HY5 in regulation of genes involved in nitrogen uptake and assimilation in plants.…”

“…Recently, it has been demonstrated in cotton that GhHY5 gets activated by light in shoots, and it migrates to root to enhance nitrogen uptake by positively regulating the expression of GhNRT1.1 (Wang et al, 2023). Phosphorus acquisition in Arabidopsis is also known to be facilitated by the red light through HY5 (Sakuraba et al, 2018).…”

SummaryELONGATED HYPOCOTYL 5 (HY5), a bZIP‐type transcription factor, is a master regulator of light‐mediated responses. ELONGATED HYPOCOTYL 5 binds to the promoter of c. 3000 genes, thereby regulating various physiological and biological processes, including photomorphogenesis, flavonoid biosynthesis, root development, response to abiotic stress and nutrient homeostasis. In recent decades, it has become clear that light signaling plays a crucial role in promoting nutrient uptake and assimilation. Recent studies have revealed the molecular mechanisms underlying such encouraging effects and the crucial function of the transcription factor HY5, whose activity is regulated by many photoreceptors. The discovery that HY5 directly activates the expression of genes involved in nutrient uptake and utilization, including several nitrogen, iron, sulphur, phosphorus and copper uptake and assimilation‐related genes, enhances our understanding of how light signaling regulates uptake and utilisation of multiple nutrients in plants. Here, we review recent advances in the role of HY5 in light‐dependent nutrient uptake and utilization.

“…The leucine zipper is a dimerization motif consisting of a heptad repetition of leucines or other bulky hydrophobic amino acids, located nine units away from the C-terminus. Members of the bZIP family have been discovered in several plants, such as cucumber [ 15 ], cassava [ 16 ], tomato [ 17 ], chrysanthemum [ 18 ], etc. CmbZIP1 was believed to adversely affect the branching of chrysanthemum shoots [ 18 ].…”

Decapitation is an essential agricultural practice and is a typical method for analyzing shoot branching. However, it is unclear exactly how decapitation controls branching. In this study, the decapitation of sunflower plants led to the development of lateral buds, accompanied by a decrease in indole-3-acetic acid (IAA) and abscisic acid (ABA) levels and an increase in cytokinin (CK) levels. Additionally, 82 members of the HabZIP family were discovered and categorized into 9 groups, using phylogenetic and conservative domain analysis. The intron/exon structure and motif compositions of HabZIP members were also investigated. Based on tissue-specific expression and expression analysis following decapitation derived from the transcriptome, several HabZIP members may be involved in controlling decapitation-induced bud outgrowth. Therefore, it is hypothesized that the dynamic variations in hormone levels, in conjunction with particular HabZIP genes, led to the development of axillary buds in sunflowers following decapitation.
