Further analysis of barley MORC1 using a highly efficient RNA-guided Cas9 gene-editing system.

ABSTRACT: Microrchidia (MORC) proteins comprise a family of proteins that have been identified in prokaryotes and eukaryotes. They are defined by two hallmark domains: a GHKL-type ATPase and an S5-fold. In plants, MORC proteins were first discovered in a genetic screen for Arabidopsis thaliana mutants compromised for resistance to a viral pathogen. Subsequent studies expanded their role in plant immunity and revealed their involvement in gene silencing and genome stabilization. Little is known about the role of MORC proteins of cereals, especially because knockout (KO) mutants were not available and assessment of loss of function relied only on RNAi strategies, which were arguable, given that MORC proteins in itself are influencing gene silencing. Here, we used a Streptococcus pyogenes Cas9 (SpCas9)
