A list of species from which PCR using mudrA-specific primers was attempted. Abbreviations and primers are as listed in “Materials and Methods.” Sequences similar to mudrA in maize were successfully amplified from most species tested.

    • F1-a  No. of clones from a given PCR amplification sequenced.

    • F1-b  Sequence contains no stop or missense mutations.

    • F1-c  Sequence previously available.

    • F1-d  No successful amplification.
