BackgroundCRISPR has been increasingly used for plant genetic improvements because of its high efficiency and precision. Recently, the authors have reported the possibility of homology-directed repair (HDR) using CRISPR/Cas9 through woody plants such as poplar. HDR often replaces nucleotides with one donor DNA template (DDT), including homologous sequences.MethodsCRISPR–Cas9 was recruited, and three variables, Agrobacteria inoculator concentration, pDDT/pgRNA ratio, and homologous arm length, were designed to integrate nptII and 2XCamV 35S into the MKK2 promoter zone.ResultsHere, we showed that recovered poplars on kanamycin-supplemented media exhibited enhanced expression of MKK2 affected by the precise integration of 2XcamV 35S and nptII, improving biochemical and phenotypic properties. Our findings confirmed that Agrobacterium inoculator OD600 = 2.5, increased DDT numbers during cell division to 4:1 pDDT/pgRNA, and optimized homologous arms 700 bp caused efficient HDR and increased MKK2 expression.ConclusionEfficient transformations resulted from optimized variables, directly affecting the HDR efficiency through woody plants such as poplar.</p
