Transgenic Improvement for Biotic Resistance of Crops. Int J Mol Sci 2022; 23:ijms232214370. [PMID: 36430848 PMCID: PMC9697442 DOI: 10.3390/ijms232214370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 11/15/2022] [Accepted: 11/17/2022] [Indexed: 11/22/2022] Open
Abstract
Biotic constraints, including pathogenic fungi, viruses and bacteria, herbivory insects, as well as parasitic nematodes, cause significant yield loss and quality deterioration of crops. The effect of conventional management of these biotic constraints is limited. The advances in transgenic technologies provide a direct and directional approach to improve crops for biotic resistance. More than a hundred transgenic events and hundreds of cultivars resistant to herbivory insects, pathogenic viruses, and fungi have been developed by the heterologous expression of exogenous genes and RNAi, authorized for cultivation and market, and resulted in a significant reduction in yield loss and quality deterioration. However, the exploration of transgenic improvement for resistance to bacteria and nematodes by overexpression of endogenous genes and RNAi remains at the testing stage. Recent advances in RNAi and CRISPR/Cas technologies open up possibilities to improve the resistance of crops to pathogenic bacteria and plant parasitic nematodes, as well as other biotic constraints.

Yu H, Yang Q, Fu F, Li W. Three strategies of transgenic manipulation for crop improvement. FRONTIERS IN PLANT SCIENCE 2022; 13:948518. [PMID: 35937379 PMCID: PMC9354092 DOI: 10.3389/fpls.2022.948518] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Accepted: 06/27/2022] [Indexed: 06/15/2023]
Abstract
Heterologous expression of exogenous genes, overexpression of endogenous genes, and suppressed expression of undesirable genes are the three strategies of transgenic manipulation for crop improvement. Up to 2020, most (227) of the singular transgenic events (265) of crops approved for commercial release worldwide have been developed by the first strategy. Thirty-eight of them have been transformed by synthetic sequences transcribing antisense or double-stranded RNAs and three by mutated copies for suppressed expression of undesirable genes (the third strategy). By the first and the third strategies, hundreds of transgenic events and thousands of varieties with significant improvement of resistance to herbicides and pesticides, as well as nutritional quality, have been developed and approved for commercial release. Their application has significantly decreased the use of synthetic pesticides and the cost of crop production and increased the yield of crops and the benefits to farmers. However, almost all the events overexpressing endogenous genes remain at the testing stage, except one for fertility restoration and another for pyramiding herbicide tolerance. The novel functions conferred by the heterologously expressing exogenous genes under the control of constitutive promoters are usually absent in the recipient crops themselves or perform in different pathways. However, the endogenous proteins encoded by the overexpressing endogenous genes are regulated in complex networks with functionally redundant and replaceable pathways and are difficult to confer the desirable phenotypes significantly. It is concluded that heterologous expression of exogenous genes and suppressed expression by RNA interference and clustered regularly interspaced short palindromic repeats-cas (CRISPR/Cas) of undesirable genes are superior to the overexpression of endogenous genes for transgenic improvement of crops.

Abstract
Viruses are obligate parasites that replicate intracellularly in many living organisms, including plants. Consequently, no chemicals are available that target only the virus without impacting host cells or vector organisms. The use of natural resistant varieties appears as the most reliable control strategy and remains the best and cheapest option in managing virus diseases, especially in the current ecological context of preserving biodiversity and environment in which the use of phytosanitary products becomes limited. Common bean is a grain legume cultivated mainly in Africa and Central-South America. Virus diseases of common bean have been extensively studied both by breeders to identify natural resistance genes in existing germplasms and by pathologists to understand the molecular bases of plant-virus interactions. Here we present a critical review in which we synthesize previous and recent information concerning 1) main viruses causing diseases in common bean, 2) genetic resistance to viruses in common bean, 3) the different resistance phenotypes observed and more particularly the effect of temperature, 4) the molecular bases of resistance genes to viruses in common bean, and 5) future prospects using transgenic-engineered resistant lines.

Abstract
Common bean (Phaseolus vulgaris L.) is a source of proteins for about one billion people worldwide. In Brazil, 'BRS Sublime', 'BRS Vereda', 'BRS Esteio', and 'BRS Estilo' cultivars were developed by Embrapa to offer high yield to farmers and excellent quality to final consumers. In this work, grain proteomes of these common bean cultivars were compared based on two-dimensional gel electrophoresis (2-DE) and tandem mass spectrometry (MS/MS). Principal component analysis (PCA) was applied to compare 349 matched spots in these cultivars proteomes, and all cultivars were clearly separated in PCA plot. Thirty-two differentially accumulated proteins were identified by MS. Storage proteins such as phaseolins, legumins, and lectins were the most abundant, and novel proteins were also identified. We have built a useful platform that could be used to analyze other Brazilian cultivars and genotypes of common beans.

Abstract
In plants, RNA interference (RNAi)-based antiviral defense is mediated by multigenic families of Dicer-like enzymes generating small interfering (si)RNAs from double-stranded RNA (dsRNA) produced during replication and/or transcription of RNA and DNA viruses, and Argonaute enzymes binding viral siRNAs and targeting viral RNA and DNA for siRNA-directed posttranscriptional and transcriptional silencing. Successful viruses are able to suppress or evade the production or action of viral siRNAs. In antiviral biotech approaches based on RNAi, transgenic expression or non-transgenic delivery of dsRNA cognate to a target virus pre-activates or boosts the natural plant antiviral defenses. Design of more effective antiviral RNAi strategies requires better understanding of viral siRNA biogenesis and viral anti-silencing strategies in virus-infected plants.

Abstract
The genetically modified (GM) common bean event Embrapa 5.1 was commercially approved in Brazil in 2011; it is resistant to golden mosaic virus infection. In the present work grain proteome profiles of two Embrapa 5.1 common bean varieties, Pérola and Pontal, and their non-GM counterparts were compared by two-dimensional gel electrophoresis (2-DE) followed by mass spectrometry (MS). Analyses detected 23 spots differentially accumulated between GM Pérola and non-GM Pérola and 21 spots between GM Pontal and non-GM Pontal, although they were not the same proteins in Pérola and Pontal varieties, indicating that the variability observed may not be due to the genetic transformation. Among them, eight proteins were identified in Pérola varieties, and four proteins were identified in Pontal. Moreover, we applied principal component analysis (PCA) on 2-DE data, and variation between varieties was explained in the first two principal components. This work provides a first 2-DE-MS/MS-based analysis of Embrapa 5.1 common bean grains.
