Abstract
Sorghum is a recalcitrant crop for Agrobacterium-mediated genetic transformation. Several parameters related to Agrobacterium-mediated transformation were tested to optimize sorghum transformation frequencies. In this study, we evaluated pretreatment of sorghum variety Tx430 immature embryos using Agrobacterium strain GV2260. Pretreatment of immature embryos with heat (43°C) treatment for 15 or 21 min, and centrifugation resulted in a transformation efficiency of up to 1.9% of immature embryos treated. Although further optimization to enhance transformation efficiency is required, this study contributes to the genetic validation of genes of interest and molecular breeding in sorghum plants.
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.
