{c}
<SHATTERPROOF1> is an <Arabidopsis thaliana> <gene> encoding a <MADS-box transcription factor> involved in <fruit dehiscence>. The <gene>'s product helps specify the <dehiscence zone>, the specialized region along which a mature <fruit> opens.<SHATTERPROOF MADS-box genes control seed dispersal in Arabidopsis by Sarah J. Liljegren and others>[Abstract; MADS-box genes and dehiscence-zone differentiation]{ref}
Its relationship with <SHATTERPROOF2> illustrates compensation between related <genes>. In the reported experiment, the single <mutant> did not show the novel opening defect seen when both functions were disrupted. Consequently, a normal-looking single <mutant> does not establish that <SHATTERPROOF1> has no developmental role; the appropriate comparison includes the double <mutant>.<SHATTERPROOF MADS-box genes control seed dispersal in Arabidopsis by Sarah J.
