Abstract
Auxin response factors (ARFs), as the main components of auxin signaling, play a crucial role in various processes of plant growth and development, as well as in stress response. So far, there have been no reports on the genome-wide identification of the ARF transcription factor family in Cyclocarya paliurus, a deciduous tree plant in the family Juglaceae. In this study, a total of 34 CpARF genes were identified based on whole genome sequence, and they were unevenly distributed on 16 chromosomes, with the highest distribution on chromosome 6. Domain analysis of CpARF proteins displayed that 31 out of 34 CpARF proteins contain a typical B3 domain (DBD domain), except CpARF12/ CpARF14/CpARF31, which all belong to Class VI. And 20 CpARFs (58.8%) contain an auxin_IAA binding domain, and are mainly distributed in classes I, and VI. Phylogenetic analysis showed that CpARF was divided into six classes (I-VI), each containing 4, 4, 1, 8, 4, and 13 members, respectively. Gene duplication analysis showed that there are 14 segmental duplications and zero tandem repeats were identified in the CpARF gene family of the C. paliurus genome. The Ka/Ks ratio of duplicate gene pairs indicates that CpARF genes are subjected to strong purification selection pressure. Synteny analysis showed that C. paliurus shared the highest homology in 74 ARF gene pairs with Juglans regia, followed by 73, 51, 25, and 11 homologous gene pairs with Populus trichocarpa, Juglans cathayensis, Arabidopsis, and rice, respectively. Promoter analysis revealed that 34 CpARF genes had cis-elements related to hormones, stress, light, and growth and development except for CpARF12. The expression profile analysis showed that almost all CpARF genes were differentially expressed in at least one tissue, and several CpARF genes displayed tissue-specific expression. Furthermore, 24 out of the 34 CpARF genes have significantly response to drought stress (P < 0.05), and most of them (16) being significantly down-regulated under moderate drought treatment. Meanwhile, the majority of CpARF genes (28) have significantly response to drought stress (P < 0.05), and most of them (26) are significantly down-regulated under severe drought treatment. Furthermore, 32 out of the 34 CpARF genes have significantly response to high, middle, and low salt stress under salt treatment (P < 0.05). Additionally, subcellular localization analysis confirmed that CpARF16 and CpARF32 were all localized to nucleus. Thus, our findings expand the understanding of the function of CpARF genes and provide a basis for further functional studies on CpARF genes in C. paliurus.

BMC Genomics 2024; 25:112. [PMID: 38273235 PMCID: PMC10809590 DOI: 10.1186/s12864-024-09992-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Accepted: 01/08/2024] [Indexed: 01/27/2024] Open
Abstract
BACKGROUND Auxin transcription factor (ARF) is an important transcription factor that transmits auxin signals and is involved in plant growth and development as well as stress response. However, genome-wide identification and responses to abiotic and pathogen stresses of the ARF gene family in Cucurbita pepo L, especially pathogen stresses, have not been reported. RESULTS Finally, 33 ARF genes (CpARF01 to CpARF33) were identified in C.pepo from the Cucurbitaceae genome database using bioinformatics methods. The putative protein contains 438 to 1071 amino acids, the isoelectric point is 4.99 to 8.54, and the molecular weight is 47759.36 to 117813.27 Da, the instability index ranged from 40.74 to 68.94, and the liposoluble index ranged from 62.56 to 76.18. The 33 genes were mainly localized in the nucleus and cytoplasm, and distributed on 16 chromosomes unevenly. Phylogenetic analysis showed that 33 CpARF proteins were divided into 6 groups. According to the amino acid sequence of CpARF proteins, 10 motifs were identified, and 1,3,6,8,10 motifs were highly conserved in most of the CpARF proteins. At the same time, it was found that genes in the same subfamily have similar gene structures. Cis-elements and protein interaction networks predicted that CpARF may be involved in abiotic factors related to the stress response. QRT-PCR analysis showed that most of the CpARF genes were upregulated under NaCl, PEG, and pathogen treatment compared to the control. Subcellular localization showed that CpARF22 was localized in the nucleus. The transgenic Arabidopsis thaliana lines with the CpARF22 gene enhanced their tolerance to salt and drought stress. CONCLUSION In this study, we systematically analyzed the CpARF gene family and its expression patterns under drought, salt, and pathogen stress, which improved our understanding of the ARF protein of zucchini, and laid a solid foundation for functional analysis of the CpARF gene.

Identification and Evolutionary Analysis of the Auxin Response Factor (ARF) Family Based on Transcriptome Data from Caucasian Clover and Analysis of Expression Responses to Hormones. Int J Mol Sci 2023; 24:15357. [PMID: 37895037 PMCID: PMC10607010 DOI: 10.3390/ijms242015357] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/07/2023] [Accepted: 10/18/2023] [Indexed: 10/29/2023] Open
Abstract
Caucasian clover (Trifolium ambiguum M. Bieb.) is an excellent perennial plant in the legume family Fabaceae, with a well-developed rhizome and strong clonal growth. Auxin is one of the most important phytohormones in plants and plays an important role in plant growth and development. Auxin response factor (ARF) can regulate the expression of auxin-responsive genes, thus participating in multiple pathways of auxin transduction signaling in a synergistic manner. No genomic database has been established for Caucasian clover. In this study, 71 TaARF genes were identified through a transcriptomic database of Caucasian clover rhizome development. Phylogenetic analysis grouped the TaARFs into six (1-6) clades. Thirty TaARFs contained a complete ARF structure, including three relatively conserved regions. Physical and chemical property analysis revealed that TaARFs are unstable and hydrophilic proteins. We also analyzed the expression pattern of TaARFs in different tissues (taproot, horizontal rhizome, swelling of taproot, rhizome bud and rhizome bud tip). Quantitative real-time RT-PCR revealed that all TaARFs were responsive to phytohormones (indole-3-acetic acid, gibberellic acid, abscisic acid and methyl jasmonate) in roots, stems and leaves. These results helped elucidate the role of ARFs in responses to different hormone treatments in Caucasian clover.
