Aghaali Z, Naghavi MR. Developing benzylisoquinoline alkaloid-enriched opium poppy via CRISPR-directed genome editing: A review. BMC PLANT BIOLOGY 2024; 24:700. [PMID: 39048937 PMCID: PMC11267691 DOI: 10.1186/s12870-024-05412-x] [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: 04/20/2024] [Accepted: 07/11/2024] [Indexed: 07/27/2024]
Abstract
Among plant-derived secondary metabolites are benzylisoquinoline alkaloids (BIAs) that play a vital role in medicine. The most conspicuous BIAs frequently found in opium poppy are morphine, codeine, thebaine, papaverine, sanguinarine, and noscapine. BIAs have provided abundant clinically useful drugs used in the treatment of various diseases and ailments With an increasing demand for these herbal remedies, genetic improvement of poppy plants appears to be essential to live up to the expectations of the pharmaceutical industry. With the advent of clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated9 (Cas9), the field of metabolic engineering has undergone a paradigm shift in its approach due to its appealing attributes, such as the transgene-free editing capability, precision, selectivity, robustness, and versatility. The potentiality of the CRISPR system for manipulating metabolic pathways in opium poppy was demonstrated, but further investigations regarding the use of CRISPR in BIA pathway engineering should be undertaken to develop opium poppy into a bioreactor synthesizing BIAs at the industrial-scale levels. In this regard, the recruitment of RNA-guided genome editing for knocking out miRNAs, flower responsible genes, genes involved in competitive pathways, and base editing are described. The approaches presented here have never been suggested or applied in opium poppy so far.

Li X, Chen Y, Lin M, Wang J, Wang N, Chen Z, Chen S. A novel miRNA, Cse-miR-33, functions as an immune regulator by targeting CsTRAF6 in Chinese tongue sole (Cynoglossus semilaevis). FISH & SHELLFISH IMMUNOLOGY 2023; 134:108606. [PMID: 36758656 DOI: 10.1016/j.fsi.2023.108606] [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: 11/19/2022] [Revised: 01/25/2023] [Accepted: 02/06/2023] [Indexed: 06/18/2023]
Abstract
The tumor necrosis factor receptor-associated factor 6 (TRAF6) can act as a fundamental adaptor protein in a chain reaction of signal transduction and cascade events to finish off immune defenses. However, immunomodulatory research on TRAF6 gene is still limited in fish. In this study, a novel miRNA, Cse-miR-33 was identified from the whole genome of Chinese tongue sole (Cynoglossus semilaevis). After separate infections with three different Vibrio strains (V. harveyi, V. anguillarum, V. parahemolyticus) and one virus (nervous necrosis virus, NNV), the expressions of CsTRAF6 and Cse-miR-33 displayed significant time-dependent changes in immune related tissues and the trends were opposite in general. Through target gene prediction and dual luciferase reporter assay, Cse-miR-33 was proven to regulate CsTRAF6 by combining with 3'-UTR sequence of the gene. The results of qRT-PCR and western blotting (WB) analyses showed that Cse-miR-33 blocked the translation of CsTRAF6 protein at post-transcriptional level, rather than degrading the target mRNA. Further experiment indicated that Cse-miR-33 inhibitor largely reduced the death rate of Chinese tongue sole caused by V. harveyi and NNV. The expressions of CsTRAF6-associated immune genes (such as CsIL-1R, CsMYD88, CsIRAK1, CsTNFα, CsIL6 and CsIL8) were also significantly changed in response to Cse-miR-33 agomir and inhibitor. The study suggested that Cse-miR-33 affected the immune response via targeting CsTRAF6 in C. semilaevis, which would provide us deep insights into miRNA-mediated regulatory network and help improve the immunity in fish.

Cadavid IC, Balbinott N, Margis R. Beyond transcription factors: more regulatory layers affecting soybean gene expression under abiotic stress. Genet Mol Biol 2023; 46:e20220166. [PMID: 36706026 PMCID: PMC9881580 DOI: 10.1590/1678-4685-gmb-2022-0166] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Accepted: 11/18/2022] [Indexed: 01/28/2023] Open
Abstract
Abiotic stresses such as nutritional imbalance, salt, light intensity, and high and low temperatures negatively affect plant growth and development. Through the course of evolution, plants developed multiple mechanisms to cope with environmental variations, such as physiological, morphological, and molecular adaptations. Epigenetic regulation, transcription factor activity, and post-transcriptional regulation operated by RNA molecules are mechanisms associated with gene expression regulation under stress. Epigenetic regulation, including histone and DNA covalent modifications, triggers chromatin remodeling and changes the accessibility of transcription machinery leading to alterations in gene activity and plant homeostasis responses. Soybean is a legume widely produced and whose productivity is deeply affected by abiotic stresses. Many studies explored how soybean faces stress to identify key elements and improve productivity through breeding and genetic engineering. This review summarizes recent progress in soybean gene expression regulation through epigenetic modifications and circRNAs pathways, and points out the knowledge gaps that are important to study by the scientific community. It focuses on epigenetic factors participating in soybean abiotic stress responses, and chromatin modifications in response to stressful environments and draws attention to the regulatory potential of circular RNA in post-transcriptional processing.

Waterlogging-Stress-Responsive LncRNAs, Their Regulatory Relationships with miRNAs and Target Genes in Cucumber ( Cucumis sativus L.). Int J Mol Sci 2021; 22:ijms22158197.

Abstract
Low oxygen level is a phenomenon often occurring during the cucumber cultivation period. Genes involved in adaptations to stress can be regulated by non-coding RNA. The aim was the identification of long non-coding RNAs (lncRNAs) involved in the response to long-term waterlogging stress in two cucumber haploid lines, i.e., DH2 (waterlogging tolerant—WL-T) and DH4 (waterlogging sensitive—WL-S). Plants, at the juvenile stage, were waterlogged for 7 days (non-primed, 1xH), and after a 14-day recovery period, plants were stressed again for another 7 days (primed, 2xH). Roots were collected for high-throughput RNA sequencing. Implementation of the bioinformatic pipeline made it possible to determine specific lncRNAs for non-primed and primed plants of both accessions, highlighting differential responses to hypoxia stress. In total, 3738 lncRNA molecules were identified. The highest number (1476) of unique lncRNAs was determined for non-primed WL-S plants. Seventy-one lncRNAs were depicted as potentially being involved in acquiring tolerance to hypoxia in cucumber. Understanding the mechanism of gene regulation under long-term waterlogging by lncRNAs and their interactions with miRNAs provides sufficient information in terms of adaptation to the oxygen deprivation in cucumber. To the best of our knowledge, this is the first report concerning the role of lncRNAs in the regulation of long-term waterlogging tolerance by priming application in cucumber.

Abstract
Beyond the most crucial roles of RNA molecules as a messenger, ribosomal, and transfer RNAs, the regulatory role of many non-coding RNAs (ncRNAs) in plant biology has been recognized. ncRNAs act as riboregulators by recognizing specific nucleic acid targets through homologous sequence interactions to regulate plant growth, development, and stress responses. Regulatory ncRNAs, ranging from small to long ncRNAs (lncRNAs), exert their control over a vast array of biological processes. Based on the mode of biogenesis and their function, ncRNAs evolved into different forms that include microRNAs (miRNAs), small interfering RNAs (siRNAs), miRNA variants (isomiRs), lncRNAs, circular RNAs (circRNAs), and derived ncRNAs. This article explains the different classes of ncRNAs and their role in plant development and stress responses. Furthermore, the applications of regulatory ncRNAs in crop improvement, targeting agriculturally important traits, have been discussed.

Abstract
Climate changes and environmental stresses have significant implications on global crop production and necessitate developing crops that can withstand an array of climate changes and environmental perturbations such as irregular water-supplies leading to drought or water-logging, hyper soil-salinity, extreme and variable temperatures, ultraviolet radiations and metal stress. Plants have intricate molecular mechanisms to cope with these dynamic environmental changes, one of the most common and effective being the reprogramming of expression of stress-responsive genes. Plant microRNAs (miRNAs) have emerged as key post-transcriptional and translational regulators of gene-expression for modulation of stress implications. Recent reports are establishing their key roles in epigenetic regulations of stress/adaptive responses as well as in providing plants genome-stability. Several stress responsive miRNAs are being identified from different crop plants and miRNA-driven RNA-interference (RNAi) is turning into a technology of choice for improving crop traits and providing phenotypic plasticity in challenging environments. Here we presents a perspective review on exploration of miRNAs as potent targets for engineering crops that can withstand multi-stress environments via loss-/gain-of-function approaches. This review also shed a light on potential roles plant miRNAs play in genome-stability and their emergence as potent target for genome-editing. Current knowledge on plant miRNAs, their biogenesis, function, their targets, and latest developments in bioinformatics approaches for plant miRNAs are discussed. Though there are recent reviews discussing primarily the individual miRNAs responsive to single stress factors, however, considering practical limitation of this approach, special emphasis is given in this review on miRNAs involved in responses and adaptation of plants to multi-stress environments including at epigenetic and/or epigenomic levels.

Abstract
Crop improvement is a continuous process in agriculture which ensures ample supply of food, fodder and fiber to burgeoning world population. Despite tremendous success in plant breeding and transgenesis to improve the yield-related traits, there have been several limitations primarily with the specificity in genetic modifications and incompatibility of host species. Because of this, new breeding techniques (NBTs) are gaining worldwide attention for crop improvement programs. Among the NBTs, genome editing (GE) using site-directed nucleases (SDNs) is an important and potential technique that overcomes limitations associated with classical breeding and transgenesis. These SDNs specifically target a compatible region in the gene/genome. The meganucleases (MgN), zinc finger nucleases (ZFN), transcription activator-like effectors nucleases (TALENs), and clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated endonuclease (Cas) are being successfully employed for GE. These can be used for desired or targeted modifications of the native endogenous gene(s) or targeted insertion of cis/trans elements in the genomes of recipient organisms. Applications of these techniques appear to be endless ever since their discovery and several modifications in original technologies have further brought precision and accuracy in these methods. In this review, we present an overview of GE using SDNs with an emphasis on CRISPR/Cas system, their advantages, limitations and also practical considerations while designing experiments have been discussed. The review also emphasizes on the possible applications of CRISPR for improving economic traits in crop plants.
