[PMID: 38057586 PMCID: PMC10700493 DOI: 10.1038/s41598-023-48900-0] [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: 02/19/2023] [Accepted: 11/30/2023] [Indexed: 12/08/2023] Open
Abstract
Soil salinity adversely affects the yield and quality of crops, including carrot. During salt stress, plant growth and development are impaired by restricted water uptake and ion cytotoxicity, leading to nutrient imbalance and oxidative burst. However, the molecular mechanisms of the carrot plant response to salt stress remain unclear. The occurrence and expression of miRNAs that are potentially involved in the regulation of carrot tolerance to salinity stress were investigated. The results of small RNA sequencing revealed that salt-sensitive (DH1) and salt-tolerant (DLBA) carrot varieties had different miRNA expression profiles. A total of 95 miRNAs were identified, including 71 novel miRNAs, of which 30 and 23 were unique to DH1 and DLBA, respectively. The comparison of NGS and qPCR results allowed identification of two conserved and five novel miRNA involved in carrot response to salt stress, and which differentiated the salt-tolerant and salt-sensitive varieties. Degradome analysis supported by in silico-based predictions and followed by expression analysis of exemplary target genes pointed at genes related to proline, glutathione, and glutamate metabolism pathways as potential miRNA targets involved in salt tolerance, and indicated that the regulation of osmoprotection and antioxidant protection, earlier identified as being more efficient in the tolerant variety, may be controlled by miRNAs. Furthermore, potential miRNA target genes involved in chloroplast protection, signal transduction and the synthesis and modification of cell wall components were indicated in plants growing in saline soil.

A tissue-specific profile of miRNAs and their targets related to paeoniaflorin and monoterpenoids biosynthesis in Paeonia lactiflora Pall. by transcriptome, small RNAs and degradome sequencing. PLoS One 2023; 18:e0279992. [PMID: 36701382 PMCID: PMC9879538 DOI: 10.1371/journal.pone.0279992] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Accepted: 12/19/2022] [Indexed: 01/27/2023] Open
Abstract
Paeonia lactiflora Pall. (Paeonia) has aroused many concerns due to its extensive medicinal value, in which monoterpene glucoside paeoniflorin and its derivatives are the active chemical components. However, little is known in the molecular mechanism of monoterpenoids biosynthesis, and the regulation network between small RNAs and mRNAs in monoterpenoids biosynthesis has not been investigated yet. Herein, we attempted to reveal the tissue-specific regulation network of miRNAs and their targets related to paeoniaflorin and monoterpenoids biosynthesis in Paeonia by combining mRNA and miRNA expression data with degradome analysis. In all, 289 miRNAs and 30177 unigenes were identified, of which nine miRNAs from seven miRNA families including miR396, miR393, miR835, miR1144, miR3638, miR5794 and miR9555 were verified as monoterpenoids biosynthesis-related miRNAs by degradome sequencing. Moreover, the co-expression network analysis showed that four monoterpenoids-regulating TFs, namely AP2, MYBC1, SPL12 and TCP2, were putatively regulated by five miRNAs including miR172, miR828, miR858, miR156 and miR319, respectively. The present study will improve our knowledge of the molecular mechanisms of the paeoniaflorin and monoterpenoids biosynthesis mediated by miRNA to a new level, and provide a valuable resource for further study on Paeonia.

Abstract
BACKGROUND Noncoding RNAs (ncRNAs), such as microRNAs (miRNAs), small interfering RNAs (siRNAs) and long noncoding RNAs (lncRNAs), play significant regulatory roles in plant development and secondary metabolism and are involved in plant response to biotic and abiotic stresses. They have been intensively studied in model systems and crops for approximately two decades and massive amount of information have been obtained. However, for medicinal plants, ncRNAs, particularly their regulatory roles in bioactive compound biosynthesis, are just emerging as a hot research field. OBJECTIVE This review aims to summarize current knowledge on herbal ncRNAs and their regulatory roles in bioactive compound production. RESULTS So far, scientists have identified thousands of miRNA candidates from over 50 medicinal plant species and 11794 lncRNAs from Salvia miltiorrhiza, Panax ginseng, and Digitalis purpurea. Among them, more than 30 miRNAs and five lncRNAs have been predicted to regulate bioactive compound production. CONCLUSION The regulation may achieve through various regulatory modules and pathways, such as the miR397-LAC module, the miR12112-PPO module, the miR156-SPL module, the miR828-MYB module, the miR858-MYB module, and other siRNA and lncRNA regulatory pathways. Further functional analysis of herbal ncRNAs will provide useful information for quality and quantity improvement of medicinal plants.

Identification, evolution and expression analysis of WRKY gene family in Eucommia ulmoides. Genomics 2021; 113:3294-3309. [PMID: 34022347 DOI: 10.1016/j.ygeno.2021.05.011] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Revised: 03/31/2021] [Accepted: 05/17/2021] [Indexed: 11/20/2022]
Abstract
The WRKY transcription factors is one of the largest families of transcription factors (TFs) in plants and involved in multiple biological processes. However, the role of the WRKY family had not been reported in Eucommia ulmoides. In this study, 45 WRKY genes (EuWRKY1-45) with conserved WRKY domain were identified in E. ulmoides and classified into three groups. The group II was further divided into five subgroups based on phylogenetic analysis, and each clade was well supported by the conserved motifs. All the genes were located on 34 different scaffolds respectively. A number of development-, light-, hormone-, and stress-related elements were randomly distributed in the promoter sequences of EuWRKYs. Expression profiles indicated that EuWRKY genes were involved in leaf development, and majority of EuWRKYs genes were highly expressed in leaf buds. Co-expression analysis of WRKYs suggested an intricate interplay of growth-related responses. EuWRKY4 was involved in a complex proteins interaction network. Collectively, our results provide extensive insights into the WRKY gene family, thereby contributing to the screening of additional candidate genes in E. ulmoides.

Abstract
As the second natural rubber resource, Eucommia ulmoides rubber (EUR) from Eucommia ulmoides Oliver is mainly composed of trans-1,4-polyisoprene, which is the isomer of natural rubber cis-1,4-polyisoprene from Hevea brasiliensis. In the past few years, the great potential application of EUR has received increasing attention, and there is a growing awareness that the natural polymer EUR could become an emerging research topic in field of the novel materials due to its unique and excellent duality of both rubber and plastic. To gain insight into its further development, in this review, the extraction, structure, physicochemical properties, and modification of EUR are discussed in detail. More emphasis on the potential applications in the fields of the environment, agriculture, engineering, and biomedical engineering is summarized. Finally, some insights into the challenges and perspectives of EUR are also suggested.
