Abstract excerpt

The phytohormone cytokinin has diverse functions in plants, most of which have been primarily elucidated in the eudicotyledonous plant Arabidopsis (Arabidopsis thaliana). To further characterize the role of cytokinin in a monocot, we used CRISPR-Cas9 to generate rice (Oryza sativa) lines with frameshift alleles in genes encoding the 4 putative histidine kinase (HK) cytokinin receptors, resulting in all single and...
