Abstract
The tissue culture process is usually involved in gene transfer and genome editing in plants. Like other species, there is enormous variation among wheat genotypes in tissue culture response. In the rapidly advancing system of CRISPR/Cas9 for genome editing, particle bombardment has received increasing attention as a delivery method for a large amount of nucleic acids and RNA-protein complexes. However, the efficiency of transformation by particle bombardment has been low in wheat, and only a limited number of varieties have been transformed. In this study, replacement of maltose with trehalose as an osmolyte for high osmotic treatment for the protection of tissues from physical impacts improved callus formation in immature wheat embryos and efficiency of transformation and genome editing in varieties that are relatively poor in tissue culture response. The range of varieties amenable to biolistic transformation and genome editing may be expanded by this modification.
期刊介绍：
Plant Biotechnology is an international, open-access, and online journal, published every three months by the Japanese Society for Plant Biotechnology. The journal, first published in 1984 as the predecessor journal, “Plant Tissue Culture Letters” and became its present form in 1997 when the society name was renamed to Japanese Society for Plant Cell and Molecular Biology, publishes findings in the areas from basic- to application research of plant biotechnology. The aim of Plant Biotechnology is to publish original and high-impact papers, in the most rapid turnaround time for reviewing, on the plant biotechnology including tissue culture, production of specialized metabolites, transgenic technology, and genome editing technology, and also on the related research fields including molecular biology, cell biology, genetics, plant breeding, plant physiology and biochemistry, metabolic engineering, synthetic biology, and bioinformatics.
