Yang E, Zheng M, Zou X, Huang X, Yang H, Chen X, Zhang J. Global Transcriptomic Analysis Reveals Differentially Expressed Genes Involved in Embryogenic Callus Induction in Drumstick ( Moringa oleifera Lam.). Int J Mol Sci 2021; 22:ijms222212130. [PMID: 34830008 PMCID: PMC8619801 DOI: 10.3390/ijms222212130] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2021] [Revised: 11/01/2021] [Accepted: 11/06/2021] [Indexed: 12/25/2022] Open
Abstract
The plant embryogenic callus (EC) is an irregular embryogenic cell mass with strong regenerative ability that can be used for propagation and genetic transformation. However, difficulties with EC induction have hindered the breeding of drumstick, a tree with diverse potential commercial uses. In this study, three drumstick EC cDNA libraries were sequenced using an Illumina NovaSeq 6000 system. A total of 7191 differentially expressed genes (DEGs) for embryogenic callus development were identified, of which 2325 were mapped to the KEGG database, with the categories of plant hormone signal transduction and Plant-pathogen interaction being well-represented. The results obtained suggest that auxin and cytokinin metabolism and several embryogenesis-labeled genes are involved in embryogenic callus induction. Additionally, 589 transcription factors from 20 different families were differentially expressed during EC formation. The differential expression of 16 unigenes related to auxin signaling pathways was validated experimentally by quantitative real time PCR (qRT-PCR) using samples representing three sequential developmental stages of drumstick EC, supporting their apparent involvement in drumstick EC formation. Our study provides valuable information about the molecular mechanism of EC formation and has revealed new genes involved in this process.

MOLECULAR BREEDING : NEW STRATEGIES IN PLANT IMPROVEMENT 2021; 41:55. [PMID: 37309401 PMCID: PMC10236038 DOI: 10.1007/s11032-021-01247-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Accepted: 08/25/2021] [Indexed: 06/14/2023]
Abstract
Alkaligrass (Puccinellia tenuiflora) is a monocotyledonous halophyte pasture, which has strong tolerance to saline-alkali, drought, and chilling stresses. We have reported a high-quality chromosome-level genome and stress-responsive proteomic results in P. tenuiflora. However, the gene/protein function investigations are still lacking, due to the absent of genetic transformation system in P. tenuiflora. In this study, we established a higher efficient Agrobacterium-mediated transformation for P. tenuiflora using calluses induced from seeds. Agrobacterium strain EHA105 harbors pANIC 6B vectors that contain GUS reporter gene and Hyg gene for screening. Ten mg·L-1 hygromycin was used for selecting transgenic calluses. The optimized condition of vacuum for 10 min, ultrasonication for 10 min, and then vacuum for 10 min was used for improvement of conversion efficiency. Besides, 300 mg·L-1 timentin was the optimum antibiotics in transformation. PCR amplification exhibited that GUS gene has been successfully integrated into the chromosome of P. tenuiflora. Histochemical GUS staining and qRT-PCR analysis indicated that GUS gene has stably expressed with ß-glucuronidase activity in transgene seedlings. All these demonstrated that we have successfully established an Agrobacterium-mediated transformation system of P. tenuiflora, which provides a good platform for further gene function analysis and lays a solid foundation for molecular breeding.
