Abstract
MAIN CONCLUSION Genome-wide identification revealed 79 BpNAC genes belonging to 16 subfamilies, and their gene structures and evolutionary relationships were characterized. Expression analysis highlighted their importance in plant selenium stress responses. Paper mulberry (Broussonetia papyrifera), a deciduous arboreal plant of the Moraceae family, is distinguished by its leaves, which are abundant in proteins, polysaccharides, and flavonoids, positioning it as a novel feedstock. NAC transcription factors, exclusive to plant species, are crucial in regulating growth, development, and response to biotic and abiotic stress. However, extensive characterization of the NAC family within paper mulberry is lacking. In this study, 79 BpNAC genes were identified from the paper mulberry genome, with an uneven distribution across 13 chromosomes. A comprehensive, genome-wide analysis of BpNACs was performed, including investigating gene structures, promoter regions, and chromosomal locations. Phylogenetic tree analysis, alongside comparisons with Arabidopsis thaliana NACs, allowed for categorizing these genes into 16 subfamilies in alignment with gene structure and motif conservation. Collinearity analysis suggested a significant homologous relationship between the NAC genes of paper mulberry and those in Morus notabilis, Ficus hispida, Antiaris toxicaria, and Cannabis sativa. Integrating transcriptome data and Se content revealed that 12 BpNAC genes were associated with selenium biosynthesis. Subsequent RT-qPCR analysis corroborated the correlation between BpNAC59, BpNAC62 with sodium selenate, and BpNAC55 with sodium selenite. Subcellular localization experiments revealed the nuclear functions of BpNAC59 and BpNAC62. This study highlights the potential BpNAC transcription factors involved in selenium metabolism, providing a foundation for strategically breeding selenium-fortified paper mulberry.

Genome-wide identification of the NAC transcription factor family and regulation of metabolites under salt stress in Isatis indigotica. Int J Biol Macromol 2023; 240:124436. [PMID: 37068542 DOI: 10.1016/j.ijbiomac.2023.124436] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Revised: 03/28/2023] [Accepted: 04/03/2023] [Indexed: 04/19/2023]
Abstract
NAC (NAM, ATAF1/2 and CUC2) transcription factors (TFs) are a class of TFs families unique to plants, which not only play an important role in the growth and developmental stages of plants but also function in response to stress and regulation of secondary metabolite biosynthesis. However, there are few studies on NAC genes in the medicinal plant Isatis indigotica. In this study, 96 IiNAC genes were identified based on the whole-genome data of I. indigotica, distributed in seven chromosomes and three contigs. IiNAC genes were structurally conserved and divided into 15 subgroups. Cis-elements were identified in the promoter region of the IiNAC gene in response to plant growth and development, abiotic stresses and hormones. In addition, transcriptome and metabolome data of I. indigotica leaves under salt stress were analyzed to construct a network of IiNAC gene co-expression and metabolite association. Ten differentially expressed IiNAC genes were co-expressed with 109 TFs, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses revealed that most of these genes were associated with plant growth and development and abiotic stress responses. Eleven IiNAC genes were positively associated with 72 metabolites. Eleven IiNAC genes were positively or negatively associated with 47 metabolites through 37 TFs. Commonly associated secondary metabolites include two terpenoids, abscisic acid and bilobalide, two flavonoids, dihydrokaempferol and syringaldehyde, a coumarin, 7-methoxycoumarin, an alkaloid, lupinine, and quinone dihydrotanshinone I. This study provides important data to support the identification of the NAC gene family in I. indigotica and the regulatory functions of IiNAC genes in metabolites under salt stress.

Genome-Wide Investigation of the NAC Transcription Factor Family in Apocynum venetum Revealed Their Synergistic Roles in Abiotic Stress Response and Trehalose Metabolism. Int J Mol Sci 2023; 24:ijms24054578. [PMID: 36902009 PMCID: PMC10003206 DOI: 10.3390/ijms24054578] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Revised: 02/21/2023] [Accepted: 02/23/2023] [Indexed: 03/02/2023] Open
Abstract
NAC (NAM, ATAF1/2, and CUC2) transcription factors (TFs) are one of the most prominent plant-specific TF families and play essential roles in plant growth, development and adaptation to abiotic stress. Although the NAC gene family has been extensively characterized in many species, systematic analysis is still relatively lacking in Apocynum venetum (A. venetum). In this study, 74 AvNAC proteins were identified from the A. venetum genome and were classified into 16 subgroups. This classification was consistently supported by their gene structures, conserved motifs and subcellular localizations. Nucleotide substitution analysis (Ka/Ks) showed the AvNACs to be under the influence of strong purifying selection, and segmental duplication events were found to play the dominant roles in the AvNAC TF family expansion. Cis-elements analysis demonstrated that the light-, stress-, and phytohormone-responsive elements being dominant in the AvNAC promoters, and potential TFs including Dof, BBR-BPC, ERF and MIKC_MADS were visualized in the TF regulatory network. Among these AvNACs, AvNAC58 and AvNAC69 exhibited significant differential expression in response to drought and salt stresses. The protein interaction prediction further confirmed their potential roles in the trehalose metabolism pathway with respect to drought and salt resistance. This study provides a reference for further understanding the functional characteristics of NAC genes in the stress-response mechanism and development of A. venetum.
