The maize proteins were compared against the Arabidopsis protein set using BLASTP (see text for details). Maize query sequences are listed that did not match any Arabidopsis sequences at the 1e-5 level. Not listed: zeins, some sequences of highly biased composition and putative maize-specific proteins. Brackets () are used to show related entries; for example, BETL2 has GenBank accession number CAB44662, and BETL3 CAB44663.
