Mutation introduced in DDTFR10/A gene of ethylene response element-binding protein (EREBP) family through CRISPR/Cas9 genome editing confers increased Fusarium wilt tolerance in tomato. PHYSIOLOGY AND MOLECULAR BIOLOGY OF PLANTS : AN INTERNATIONAL JOURNAL OF FUNCTIONAL PLANT BIOLOGY 2023; 29:1-10. [PMID: 36733839 PMCID: PMC9886765 DOI: 10.1007/s12298-022-01273-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Revised: 12/20/2022] [Accepted: 12/21/2022] [Indexed: 06/18/2023]
Abstract
We investigated the role of the DDTFR10/A gene of the ethylene response element-binding protein (EREBP) family through the CRISPR/Cas9 genome editing approach. The associated role of this gene in tomato fruit ripening was known. The involvement of ripening-regulatory proteins in plant defense has been documented; therefore, to find the involvement of the DDTFR10/A gene in host susceptibility, we introduced the mutation in DDTFR10/A gene through CRISPR/cas9 in the genome of the tomato plant. The 50% biallelic and 50% homozygous mutations were observed in the T0 generation. The CRISPR/Cas9 edited plants showed 40% reduced symptoms of Fusarium wilt compared to control plants (non-edited). The DDTFR10/A gene expression in tomato plants was evaluated against biotic (Fusarium wilt) and abiotic (salinity) stresses, and the upregulated expression of this gene was found under both challenges. However, a comparative increase in DDTFR10/A gene expression was observed in tomato plants upon inoculation with Fusarium oxysporum f. sp. lycopersici. The phenotypic assay performed on edited tomato plants demonstrated the role of the DDTFR10/A gene in contributing toward susceptibility against Fusarium wilt.

BMC PLANT BIOLOGY 2021; 21:97. [PMID: 33596830 PMCID: PMC7890976 DOI: 10.1186/s12870-021-02868-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Accepted: 02/01/2021] [Indexed: 05/03/2023]
Abstract
BACKGROUND Banana is a tropical fruit with a high economic impact worldwide. Cold stress greatly affects the development and production of banana. RESULTS In the present study, we investigated the functions of MaMAPK3 and MaICE1 involved in cold tolerance of banana. The effect of RNAi of MaMAPK3 on Dajiao (Musa spp. 'Dajiao'; ABB Group) cold tolerance was evaluated. The leaves of the MaMAPK3 RNAi transgenic plants showed wilting and severe necrotic symptoms, while the wide-type (WT) plants remained normal after cold exposure. RNAi of MaMAPK3 significantly changed the expressions of the cold-responsive genes, and the oxidoreductase activity was significantly changed in WT plants, while no changes in transgenic plants were observed. MaICE1 interacted with MaMAPK3, and the expression level of MaICE1 was significantly decreased in MaMAPK3 RNAi transgenic plants. Over-expression of MaICE1 in Cavendish banana (Musa spp. AAA group) indicated that the cold resistance of transgenic plants was superior to that of the WT plants. The POD P7 gene was significantly up-regulated in MaICE1-overexpressing transgenic plants compared with WT plants, and the POD P7 was proved to interact with MaICE1. CONCLUSIONS Taken together, our work provided new and solid evidence that MaMAPK3-MaICE1-MaPOD P7 pathway positively improved the cold tolerance in monocotyledon banana, shedding light on molecular breeding for the cold-tolerant banana or other agricultural species.

Insertional Mutagenesis Approaches and Their Use in Rice for Functional Genomics. PLANTS 2019; 8:plants8090310. [PMID: 31470516 PMCID: PMC6783850 DOI: 10.3390/plants8090310] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/12/2019] [Revised: 08/07/2019] [Accepted: 08/07/2019] [Indexed: 01/01/2023]
Abstract
Insertional mutagenesis is an indispensable tool for engendering a mutant population using exogenous DNA as the mutagen. The advancement in the next-generation sequencing platform has allowed for faster screening and analysis of generated mutated populations. Rice is a major staple crop for more than half of the world's population; however, the functions of most of the genes in its genome are yet to be analyzed. Various mutant populations represent extremely valuable resources in order to achieve this goal. Here, we have reviewed different insertional mutagenesis approaches that have been used in rice, and have discussed their principles, strengths, and limitations. Comparisons between transfer DNA (T-DNA), transposons, and entrapment tagging approaches have highlighted their utilization in functional genomics studies in rice. We have also summarised different forward and reverse genetics approaches used for screening of insertional mutant populations. Furthermore, we have compiled information from several efforts made using insertional mutagenesis approaches in rice. The information presented here would serve as a database for rice insertional mutagenesis populations. We have also included various examples which illustrate how these populations have been useful for rice functional genomics studies. The information provided here will be very helpful for future functional genomics studies in rice aimed at its genetic improvement.
