Description:
We selected mutant K2942 from the sequenced ethyl methanesulfonate (EMS) population in tetraploid wheat Kronos (Krasileva et al., 2017, PNAS 14:E913). K2942 has a mutation in the miR156 target site of SPL-A4. The resulting miR156-resistant allele (rSPL-A4) was crossed to wildtype Kronos and then back-crossed three times to reduce background mutations. BC3F4 seeds homozygous for the mutation are the ones deposited here.
