“…Many components in hormone signaling are targets of miRNAs, and the interactions of these components and the miRNAs enable plants to regulate their growth, development, and differentiation rapidly and effectively. This signaling is done by selecting miRNAs as intermediates to control hormone responses or, conversely, by using hormones to regulate specific miRNA levels (Jodder, 2020;Li et al, 2020;Yu and Wang, 2020). There is evidence indicating that miRNAs can diffuse in tissues as inhibitor signals, so they play an elaborate role in tissue differentiation (Chen and Rechavi, 2021).…”

Small RNAs are short non-coding RNAs with a length ranging between 20 and 24 nucleotides. Of these, microRNAs (miRNAs) play a distinct role in plant development. miRNAs control target gene expression at the post-transcriptional level, either through direct cleavage or inhibition of translation. miRNAs participate in nearly all the developmental processes in plants, such as juvenile-to-adult transition, shoot apical meristem development, leaf morphogenesis, floral organ formation, and flowering time determination. This review summarizes the research progress in miRNA-mediated gene regulation and its role in plant development, to provide the basis for further in-depth exploration regarding the function of miRNAs and the elucidation of the molecular mechanism underlying the interaction of miRNAs and other pathways.

Background: Auxin signalling plays a crucial role in plant growth and development. Although the auxin response factor (ARF) gene family has been studied in some plant species, its structural features, molecular evolution, and expression profile in Zizania latifolia (Z. latifolia) are still not clear.Results: Our study identified 33 putative YSL genes from the whole Z. latifolia genome. Furthermore, a comprehensive overview of the ZlARFs was undertaken, including phylogenetic relationship, gene structures, conserved domains, synteny, Ka/Ks, motifs, and subcellular locations of the gene product. Synteny analyses and the calculation of Ka/Ks values suggested that all 57 orthologous/paralogous gene pairs between Z. latifolia and Z. latifolia, Z. latifolia and Oryza sativa have experienced strong purifying selection. The phylogenetic analysis of ARFs indicated that the ZlARFs can be divided into 6 classes and that most ZlARFs from Z. latifolia have closer relationships with Oryza sativa than with Arabidopsis. RNA-Seq data and qRT-PCR analyses showed that ZlARF genes were expressed in TDF treatment and U. esculenta infection, while some ZlARFs exhibited high expression levels only in U. esculenta infection. Meanwhile, the interaction networks and gene ontology (GO) term of the ZlARF genes were constructed and 23 ZlARF co-expressed genes were identified, most of which were down-regulated involve auxin-activated signalling pathway in after swelling stem formation. Transcriptome analysis results verified the relevant functions of ARF genes, and most ZlARF genes regulated physiological processes in response to differential cell expansion. Conclusion: Comprehensive bioinformation analysis of the auxin response factor gene family (ARF) in Z. latifolia and its association with swelling stem formation after U. esculenta infection. The bioinformatic and RNA-Seq analyses provided valuable information for further study on the regulation of the growth and development of swelling stem formation by ZlARFs in Z. latifolia.

“…The tir1/afb quadruple mutant exhibits severe developmental defects, indicating the key role of TAAR-dependent auxin signaling [ 61 ]. Previous studies have demonstrated that the miR393-TIR1/AFB regulatory module plays a critical role in root system architecture, leaf development, auxin response and plant response to abiotic and biotic stress ( Figure 1 C and Figure 2 C) [ 12 ]. Under salt stress, NaCl induces miR393 expression and inhibits TIR1/AFB2 via enhancing the transcription of miR393a, and then inhibits LR initiation, emergence and elongation ( Figure 2 C) [ 62 ].…”

“…In addition to the precise regulation of auxin biosynthesis and distribution, the auxin signaling pathway is subject to locus-specific control by microRNAs (miRNA) [ 12 , 13 ]. The miRNAs are short, single-stranded nucleic acid molecules (~21–24 nucleotides) that repress target gene expression as an additional layer of regulation of plant growth, and stress responses in plants [ 14 ].…”

Auxin, primarily indole-3-acetic acid (IAA), is a versatile signal molecule that regulates many aspects of plant growth, development, and stress response. Recently, microRNAs (miRNAs), a type of short non-coding RNA, have emerged as master regulators of the auxin response pathways by affecting auxin homeostasis and perception in plants. The combination of these miRNAs and the autoregulation of the auxin signaling pathways, as well as the interaction with other hormones, creates a regulatory network that controls the level of auxin perception and signal transduction to maintain signaling homeostasis. In this review, we will detail the miRNAs involved in auxin signaling to illustrate its in planta complex regulation.
