“…Thus, the Aux/IAA-ARF modules govern diverse processes of plant growth and development such as apical dominance, later root initiation and formation, and vascular differentiation, hypocotyl xylem expansion and cambium homeostasis, fruit development and maturation, cell division, expansion, and differentiation [ 11 , 12 ]. For example, AtARF4 in Arabidopsis acts as a transcriptional repressor to regulate shoot regeneration through competing the interaction of AtIAA12 with AtARF5 [ 13 ]; MdARF13 in apple serves as a negative regulator of the anthocyanin metabolic pathway [ 14 ]; AtARF7 and AtARF19 confer the gravitropism and phototropism of plant hypocotyls through mediating the asymmetric expression of AtSAUR genes in Arabidopsis [ 15 ]; MdARF8 facilitates lateral root formation in apple [ 16 ]. Noticeably, the Aux/IAA-ARF modules perform their functions in not only organ-dependent but also cell type-dependent way.…”

Background Auxin responsive factor (ARF) family is one of core components in auxin signalling pathway, which governs diverse developmental processes and stress responses. Blueberry is an economically important berry-bearing crop and prefers to acidic soil. However, the understandings of ARF family has not yet been reported in blueberry. Results In the present study, 60 ARF genes (VcARF) were identified in blueberry, and they showed diverse gene structures and motif compositions among the groups and similar within each group in the phylogenetic tree. Noticeably, 9 digenic, 5 trigenic and 6 tetragenic VcARF pairs exhibited more than 95% identity to each other. Computational analysis indicated that 23 VcARFs harbored the miRNA responsive element (MRE) of miR160 or miR167 like other plant ARF genes. Interestingly, the MRE of miR156d/h-3p was observed in the 5’UTR of 3 VcARFs, suggesting a potentially novel post-transcriptional control. Furthermore, the transcript accumulations of VcARFs were investigated during fruit development, and three categories of transcript profiles were observed, implying different functional roles. Meanwhile, the expressions of VcARFs to different pH conditions (pH4.5 and pH6.5) were surveyed in pH-sensitive and tolerant blueberry species, and a number of VcARFs showed different transcript accumulations. More importantly, distinct transcriptional response to pH stress (pH6.5) were observed for several VcARFs (such as VcARF6s and VcARF19-3/19–4) between pH-sensitive and tolerant species, suggesting their potential roles in adaption to pH stress. Conclusions Sixty VcARF genes were identified and characterized, and their transcript profiles were surveyed during fruit development and in response to pH stress. These findings will contribute to future research for eliciting the functional roles of VcARFs and regulatory mechanisms, especially fruit development and adaption to pH stress.

“…Extensive studies have suggested that ARF proteins are involved in distinct developmental processes. In Arabidopsis, numerous ARF genes have been implicated in embryogenesis (ARF5 and ARF17) [37], root growth (ARF7, ARF10, ARF16, and ARF19) [38][39][40][41], hypocotyl growth (ARF6, ARF7, ARF8, and ARF19) [42][43][44], shoot regeneration (ARF4 and ARF5) [45], flower development (ARF2, ARF3, ARF6, and ARF8) [46,47] and senescence (ARF1 and ARF2) [48]. In the case of rice, genetic studies show that the functions of ARFs are different from the functions of Arabidopsis.…”

As an important gas signaling molecule, hydrogen sulfide (H2S) plays a crucial role in regulating cold tolerance. H2S cooperates with phytohormones such as abscisic acid, ethylene, and salicylic acid to regulate the plant stress response. However, the synergistic regulation of H2S and auxin in the plant response to cold stress has not been reported. This study showed that sodium hydrosulfide (NaHS, an H2S donor) treatment enhanced the cold stress tolerance of cucumber seedlings and increased the level of auxin. CsARF5, a cucumber auxin response factor (ARF) gene, was isolated, and its role in regulating H2S-mediated cold stress tolerance was described. Transgenic cucumber leaves overexpressing CsARF5 were obtained. Physiological analysis indicated that overexpression of CsARF5 enhanced the cold stress tolerance of cucumber and the regulation of the cold stress response by CsARF5 depends on H2S. In addition, molecular assays showed that CsARF5 modulated cold stress response by directly activating the expression of the dehydration-responsive element-binding (DREB)/C-repeat binding factor (CBF) gene CsDREB3, which was identified as a positive regulator of cold stress. Taken together, the above results suggest that CsARF5 plays an important role in H2S-mediated cold stress in cucumber. These results shed light on the molecular mechanism by which H2S regulates cold stress response by mediating auxin signaling; this will provide insights for further studies on the molecular mechanism by which H2S regulates cold stress. The aim of this study was to explore the molecular mechanism of H2S regulating cold tolerance of cucumber seedlings and provide a theoretical basis for the further study of cucumber cultivation and environmental adaptability technology in winter.

“…In the LAV group, Arabidopsis thaliana FUSCA3 regulates seed maturation ( Luerssen et al., 1998 ); maize ZmABI19 is essential for the initiation of grain filling ( Yang et al., 2021 ); and overexpression of citrus FUSCA3 promotes somatic embryogenesis ( Liu et al., 2018 ). In the ARF group, overexpression of AtARF8 affects the development of fruit, hypocotyl and roots ( Tian et al., 2004 ); AtARF4 regulates the regeneration of shoot meristems ( Zhang et al., 2021 ); and OsARF8 regulates hypocotyl elongation ( Yang et al., 2006 ). In the RAV group, rice ( Oryza sativa L.) RAV members regulate flowering time ( Osnato et al., 2020 ), whereas overexpression of strawberry ( Fragaria × ananassa ) FaRAV1 increases anthocyanin production ( Zhang et al., 2020 ).…”

B3 is a class of plant-specific transcription factors with important roles in plant development and growth. Here, we identified 69 B3 transcription factors in Brachypodium distachyon that were unevenly distributed across all five chromosomes. The ARF, REM, LAV, and RAV subfamilies were grouped based on sequence characteristics and phylogenetic relationships. The phylogenetically related members in the B3 family shared conserved domains and gene structures. Expression profiles showed that B3 genes were widely expressed in different tissues and varied in response to different abiotic stresses. BdB3-54 protein from the REM subfamily was located in the nucleus by subcellular localization and processed transcriptional activation activity. Overexpression of BdB3-54 in Arabidopsis increased primary root length. Our study provides a basis for further research on the functions of BdB3 genes.
