“…Under long daylight, salicylic acid (SA) can induce flowering in Wolffia microscopic of short daylight plant [72], salicylic acid treatment can promote more flowering in citrus [73], and salicylic acid (SA) accumulation can inhibit the development of stamen abscission in tung tree [74]. Flower bud differentiation and flowering are two distinct stages in most woody plants [75,76], and it can also be hypothesized that VcSPL53 is involved in floral initiation and flowering in blueberry. In summary, the blueberry VcSPL gene family has a significant role in blueberry plant growth, leaf development, flowering regulation, and abiotic stress, especially in the process of floral initiation and induction.…”

The SPL gene is a plant-specific transcription factor involved in the regulation of plant growth and development, which have been identified in woody plants. The process of floral bud differentiation affects the timing of flowering and fruit set and regulates plant growth, however, the mechanism of regulation of flower development by SPL genes is less studied. In this study, 56 VcSPL genes were identified in the tetraploid blueberry. The VcSPL gene family was classified into six subfamilies, and analysis of cis-elements showed that VcSPL genes were regulated by light, phytohormones (abscisic acid, MeJA), and low temperature. In the evolutionary analysis, segmental replication may play an important role in VcSPL gene amplification. Interestingly, we also studied diploid blueberry (Bilberry), in which 24 SPL genes were identified, and 36 homologous pairs were found, suggesting a high degree of convergence in the syntenic relationship between blueberry (Vaccinium corymbosum L) and bilberry (Vaccinium darrowii). Based on the expression profile, VcSPL genes were expressed at high levels in flowers, shoots, and roots, indicating a diversity of gene functions. Then we selected 20 differentially-expressed SPL genes to further investigate the role of VcSPL in floral induction and initiation. It showed that the genes VcSPL40, VcSPL35, VcSPL45, and VcSPL53 may play a crucial role in the blueberry floral transition phase (from vegetative growth to flower initiation). These results provided important information for understanding and exploring the role of VcSPLs in flower morphogenesis and plant growth.

“…However, the expression pattern of miR172 is different ( Wang et al, 2011 ). An integrated analysis of mRNA and miRNA found that the MsSVP/miR172/mssap2-like module controls the expression of MsLFY by responding to gibberellin signals and stimulates the transition from vegetative growth to reproductive growth in Magnolia × soulangeana ( Sun et al, 2020 ). Furthermore, overexpression of miR156 in transgenic Canadian poplar plants reduced the expression of miR156-targeted SPL genes and miR172, leading to the prolonged juvenile phase ( Wang et al, 2011 ).…”

MicroRNAs (miRNAs) are small (∼21-nucleotides) non-coding RNAs found in plant and animals. MiRNAs function as critical post-transcriptional regulators of gene expression by binding to complementary sequences in their target mRNAs, leading to mRNA destabilization and translational inhibition. Plant miRNAs have some distinct characteristics compared to their animal counterparts, including greater evolutionary conservation and unique miRNA processing methods. The lifecycle of a plant begins with embryogenesis and progresses through seed germination, vegetative growth, reproductive growth, flowering and fruiting, and finally senescence and death. MiRNAs participate in the transformation of plant growth and development and directly monitor progression of these processes and the expression of certain morphological characteristics by regulating transcription factor genes involved in cell growth and differentiation. In woody plants, a large and rapidly increasing number of miRNAs have been identified, but their biological functions are largely unknown. In this review, we summarize the progress of miRNA research in woody plants to date. In particular, we discuss the potential roles of these miRNAs in growth, development, and biotic and abiotic stresses responses in woody plants.

“…Integrated analysis of the miRNAome, transcriptome, and degradome analyses can enhance the understanding of the genome wide co-expression patterns of miRNA-mRNA pairs and links the biological interactions of miRNA-target modules ( Liu et al., 2020a ; Wang et al., 2021 ). Integrated miRNA, transcriptome, and degradome-seq analysis of miRNA-mRNA involved in flowering of pepper ( Shu et al., 2021 ), floral development and abscission of yellow lupine ( Glazinska et al., 2019 ), female sterility of pomegranate ( Chen et al., 2020 ), male sterility of rice ( Sun et al., 2021 ), flower development across capsicum species ( Lopez-Ortiz et al., 2021 ), stamen development in moso bamboo ( Cheng et al., 2019 ), flowering induction in Lilium × formolongi ( Zhang et al., 2021 ), floral transition in Magnolia × soulangeana ‘Changchun’ ( Sun et al., 2021 ) has provided evidence demonstrated of regulatory pathways and gene networks of miRNAs and their targets associated with flowering. Moreover, studies have shown that miR319 - TCP , miR156 - SPL , miR159 - MYB , miR172 - AP2 and miR399 - PHO2 nodes play important roles in floral transition ( Waheed and Zeng, 2020 ).…”

As a candidate national flower of China, tree peony has extremely high ornamental, medicinal and oil value. However, the short florescence and rarity of early-flowering and late-flowering varieties restrict further improvement of the economic value of tree peony. Specific miRNAs and their target genes engaged in tree peony floral florescence, development and senescence remain unknown. This report presents the integrated analysis of the miRNAome, transcriptome and degradome of tree peony petals collected from blooming, initial flowering, full blooming and decay stages in early-flowering variety Paeonia ostii ‘Fengdan’, an early-flowering mutant line of Paeonia ostii ‘Fengdan’ and late-flowering variety Paeonia suffruticosa ‘Lianhe’. Transcriptome analysis revealed a transcript (‘psu.G.00014095’) which was annotated as a xyloglucan endotransglycosylase/hydrolase precursor XTH-25 and found to be differentially expressed across flower developmental stages in Paeonia ostii ‘Fengdan’ and Paeonia suffruticosa ‘Lianhe’. The miRNA-mRNA modules were presented significant enrichment in various pathways such as plant hormone signal transduction, indole alkaloid biosynthesis, arachidonic acid metabolism, folate biosynthesis, fatty acid elongation, and the MAPK signaling pathway. Multiple miRNA-mRNA-TF modules demonstrated the potential functions of MYB-related, bHLH, Trihelix, NAC, GRAS and HD-ZIP TF families in floral florescence, development, and senescence of tree peony. Comparative spatio-temporal expression investigation of eight floral-favored miRNA-target modules suggested that transcript ‘psu.T.00024044’ and microRNA mtr-miR166g-5p are involved in the floral florescence, development and senescence associated agronomic traits of tree peony. The results might accelerate the understanding of the potential regulation mechanism in regards to floral florescence, development and abscission, and supply guidance for tree peony breeding of varieties with later and longer florescence characteristics.
