= SHATTERPROOF genes
{c}
The <SHATTERPROOF genes> are the related <Arabidopsis thaliana> <genes> <SHATTERPROOF1> and <SHATTERPROOF2>, encoding <MADS-box transcription factors> involved in <fruit dehiscence>. Their developmental role connects regulation of <gene expression> to formation of the <dehiscence zone> and adjacent <lignin> deposition.<SHATTERPROOF MADS-box genes control seed dispersal in Arabidopsis by Sarah J. Liljegren and others>[Nature404, pp.766–770; Abstract]{ref}
The paired experiment matters. Compare the normal <plant>, each single <mutant>, and the double <mutant>. An effect appearing chiefly in the last comparison supplies evidence for <genetic redundancy>; observing only the normal <plant> and one single <mutant> could miss the shared function.<SHATTERPROOF MADS-box genes control seed dispersal in Arabidopsis by Sarah J. Liljegren and others>[Abstract; individual and combined gene disruptions]{ref}
The family name groups the two loci; it does not identify one fused <gene>. The opening <phenotype> also does not by itself enumerate the <transcription factors>' direct <DNA> targets. Distinguishing locus identity, regulatory activity and tissue-level outcome makes the experimental claim precise.
