Protocol for genome editing in wild allotetraploid rice Oryza alta

Abstract

Summary: We present a protocol for Agrobacterium-mediated genetic transformation and genome editing in wild allotetraploid rice Oryza alta. We detail steps to induce embryogenic calli from mature seeds and co-cultivate with Agrobacterium after infection. We further describe how to select transformed cells that proliferated from infected calli based on hygromycin resistance, resulting in regeneration of transformed plantlets with multiple edited alleles. Edited lines produced via this protocol can be used for gene functions studies and de novo domestication of O. alta.For complete details on the use and execution of this protocol, please refer to Yu et al. (2021). : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
