Genome-wide characterization of RR gene family members in Zanthoxylum armatum and the subsequent functional characterization of the C-type RR. PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2024; 214:108943. [PMID: 39032447 DOI: 10.1016/j.plaphy.2024.108943] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 07/10/2024] [Accepted: 07/15/2024] [Indexed: 07/23/2024]
Abstract
Response Regulators (RRs) are crucial regulators in plant development and stress responses, comprising A-type, B-type, C-type, and pseudo-RR subfamilies. However, previous studies have often focused on specific subfamilies, which restricts our understanding of the complete RR gene family. In this study, we conducted a comprehensive analysis of 63 RR members from Zanthoxylum armatum, using phylogenetic relationships, motif composition, cis-acting elements, gene duplication and collinearity analyses. Segmental repeats among ZaRR genes enhanced the various environmental adaptabilities of Z. armatum, and the B-type ZaRR exhibited significant collinearity with the RRs in P. trichocarpa and C. sinensis. Cis-element analysis indicated ZaRRs play a significant role in abiotic stress and phytohormone pathways, particularly in light, drought, cold, abscisic acid (ABA) and salicylic acid (SA) responses. Abundant Ethylene Response Factor (ERF) and reproduction-associated binding sites in ZaRR promoters suggested their roles in stress and reproductive processes. A-type ZaRRs were implicated in plant vegetative and reproductive growth, whereas B-type ZaRRs contributed to both growth and stress responses. C-type ZaRRs were associated with plant reproductive growth, whereas pseudo-RRs may function in plant stress responses, such as water logging, cold, and response to ethylene (ETH), SA, and jasmonic acid (JA). Ectopic expression of ZaRR24, a C-type RR, inhibits growth, induces early flowering, and shortens fruit length in Arabidopsis. ZaRR24 overexpression also affected the expression of A- and B-type RRs, as well as floral meristem and organ identity genes. These findings establish a solid and comprehensive foundation for RR gene research in Z. armatum, and provide a platform for investigating signal transduction in other woody plants.

Integrative analysis of the metabolome and transcriptome reveals the potential mechanism of fruit flavor formation in wild hawthorn ( Crataegus chungtienensis). PLANT DIVERSITY 2023; 45:590-600. [PMID: 37936817 PMCID: PMC10625895 DOI: 10.1016/j.pld.2023.02.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 01/16/2023] [Accepted: 02/05/2023] [Indexed: 11/09/2023]
Abstract
Hawthorns are important medicinal and edible plants with a long history of health protection in China. Besides cultivated hawthorn, other wild hawthorns may also have excellent medicinal and edible value, such as Crataeguschungtienensis, an endemic species distributed in the Southwest of China. In this study, by integrating the flavor-related metabolome and transcriptome data of the ripening fruit of C. chungtienensis, we have developed an understanding of the formation of hawthorn fruit quality. The results show that a total of 849 metabolites were detected in the young and mature fruit of C. chungtienensis, of which flavonoids were the most detected metabolites. Among the differentially accumulated metabolites, stachyose, maltotetraose and cis-aconitic acid were significantly increased during fruit ripening, and these may be important metabolites affecting fruit flavor change. Moreover, several flavonoids and terpenoids were reduced after fruit ripening compared with young fruit. Therefore, using the unripe fruit of C. chungtienensis may allow us to obtain more medicinal active ingredients such as flavonoids and terpenoids. Furthermore, we screened out some differentially expressed genes (DEGs) related to fruit quality formation, which had important relationships with differentially accumulated sugars, acids, flavonoids and terpenoids. Our study provides new insights into flavor formation in wild hawthorn during fruit development and ripening, and at the same time this study lays the foundation for the improvement of hawthorn fruit flavor.

Genome-wide characterization of the MBF1 gene family and its expression pattern in different tissues and stresses in Zanthoxylum armatum. BMC Genomics 2022; 23:652. [PMID: 36104767 PMCID: PMC9472409 DOI: 10.1186/s12864-022-08863-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Accepted: 08/31/2022] [Indexed: 11/18/2022] Open
Abstract
Background Multiprotein bridging factor 1 (MBF1) is a crucial transcriptional coactivator in animals, plants, and some microorganisms, that plays a necessary role in growth development and stress tolerance. Zanthoxylum armatum is an important perennial plant for the condiments and pharmaceutical industries, whereas the potential information in the genes related to stress resistance remains poorly understood in Z. armatum. Results Herein, six representative species were selected for use in a genome-wide investigation of the MBF1 family, including Arabidopsis thaliana, Oryza sativa, Populus trichocarpa, Citrus sinensis, Ginkgo biloba, and Z. armatum. The results showed that the MBF1 genes could be divided into two groups: Group I contained the MBF1a and MBF1b subfamilies, and group II was independent of the MBF1c subfamily.. Most species have at least two different MBF1 genes, and MBF1c is usually an essential member. The three ZaMBF1 genes were respectively located on ZaChr26, ZaChr32, and ZaChr4 of Zanthoxylum chromosomes. The collinearity were occurred between three ZaMBF1 genes, and ZaMBF1c showed the collinearity between Z. armatum and both P. trichocarpa and C. sinensis. Moreover, many cis-elements associated with abiotic stress and phytohormone pathways were detected in the promoter regions of MBF1 of six representative species. The ERF binding sites were the most abundant targets in the sequences of the ZaMBF1 family, and some transcription factor sites related to floral differentiation were also identified in ZaMBF1c, such as MADS, LFY, Dof, and AP2. ZaMBF1a was observed to be very highly expressed in 25 different samples except in the seeds, and ZaMBF1c may be associated with the male and female floral initiation processes. In addition, expression in all the ZaMBF1 genes could be significantly induced by water-logging, cold stress, ethephon, methyl jasmonate, and salicylic acid treatments, especially in ZaMBF1c. Conclusion The present study carried out a comprehensive bioinformatic investigation related to the MBF1 family in six representative species, and the responsiveness of ZaMBF1 genes to various abiotic stresses and phytohormone inductions was also revealed. This work not only lays a solid foundation to uncover the biological roles of the ZaMBF1 family in Z. armatum, but also provides some broad references for conducting the MBF1 research in other plants.

Integrated transcriptome and plant growth substance profiles to identify the regulatory factors involved in floral sex differentiation in Zanthoxylum armatum DC. FRONTIERS IN PLANT SCIENCE 2022; 13:976338.

Abstract
Zanthoxylum armatum is a prominent plant for food industries. Its male flowers often occur in gynogenesis plants; however, the potential mechanism remains poorly understood. Herein, a total of 26 floral sex differentiation stages were observed to select four vital phases to reveal key factors by using RNA-seq, phytohormones and carbohydrates investigation. The results showed that a selective abortion of stamen or pistil primordia could result in the floral sex differentiation in Z. armatum. Carbohydrates might collaborate with cytokinin to effect the male floral differentiation, whereas female floral differentiation was involved in SA, GA1, and ABA biosynthesis and signal transduction pathways. Meanwhile, these endogenous regulators associated with reproductive growth might be integrated into ABCDE model to regulate the floral organ differentiation in Z. armatum. Furthermore, the 21 crucial candidates were identified in co-expression network, which would contribute to uncovering their roles in floral sex differentiation of Z. armatum in further studies. To the best of our knowledge, this study was the first comprehensive investigation to link floral sex differentiation with multi-level endogenous regulatory factors in Z. armatum. It also provided new insights to explore the regulatory mechanism of floral sex differentiation, which would be benefited to cultivate high-yield varieties in Z. armatum.

Genome-wide transcriptional analysis unveils the molecular basis of organ-specific expression of isosteroidal alkaloids biosynthesis in critically endangered Fritillaria roylei Hook. PHYTOCHEMISTRY 2021; 187:112772. [PMID: 33873018 DOI: 10.1016/j.phytochem.2021.112772] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Revised: 04/03/2021] [Accepted: 04/04/2021] [Indexed: 06/12/2023]
Abstract
Fritillaria roylei Hook. is a critically endangered high altitude Himalayan medicinal plant species with rich source of pharmaceutically active structurally diverse steroidal alkaloids. Nevertheless, except few marker compounds, the chemistry of the plant remains unexplored. Therefore, in the current study, transcriptome sequencing efforts were made to elucidate isosteroidal alkaloids biosynthesis by creating first organ-specific genomic resource using bulb, stem, and leaf tissues derived from natural populations of Indian Himalayan region. Overall, 349.9 million high quality paired-end reads obtained using NovaSeq 6000 platform were assembled (de novo) into 82,848 unigenes and 31,061 isoforms. Functional annotation and organ specific differential expression (DE) analysis identified 2488 significant DE transcripts, grouped into three potential sub-clusters (sub-cluster I: 728 transcripts; sub-cluster II: 446 transcripts and Sub-cluster III: 1314 transcripts). Subsequently, pathway enrichment (GO, KEGG) and protein-protein network analysis revealed significantly higher enrichment of phenyl-propanoid and steroid backbone including terpenoid, sesquiterpenoid and triterpenoid biosynthesis in bulb. Additionally, upregulated expression of cytochrome P450, UDP-dependent Glucuronosyltransferase families and key transcription factor families (FAR1, bHLH, GRAS, C2H2, TCP and MYB) suggests 'bulb' as a primary site of MVA mediated isosteroidal alkaloids biosynthesis. The comprehensive elucidation of molecular insights in this study is a first step towards the understanding of isosteroidal alkaloid biosynthesis pathway in F. roylei. Furthermore, key genes and regulators identified here can facilitate metabolic engineering of potential bioactive compounds at industrial scale.
