"The MADS-box encodes a novel type of DNA-binding domain found so far in a diverse group of transcription factors from yeast, animals, and seed plants."[1]

"The MADS-box comprises 180 nucleotides, encoding 60 amino acids [...] MADS is an acronym for the four DNA-binding proteins MCM1 [minichromosome maintenance gene 1], AGAMOUS [...], DEFICIENS [...], and SRF [serum response factor]."[1]

The "[Antirrhinum majus mutant squamosa (squa)] SQUA is a member of a family of transcription factors which contain the MADS-box, a conserved DNA binding domain."[2]

The "MADS-box is [...] AGAGGGAAAGTACAACTGAAGAGGATAGAGAACAAGATCAATAGACAGGTGACTTT CTCAAAGAGGAGAGGTGGATTGTTGAAAAAAGCTCATGAGCTCTCTGTGCTTTGTG ATGCTGAAGTGGCTCTTATTGTCTTCTCTAATAAGGGGAAGCTATTTGAGTATTCT ACTGAT",[2] which has 174 nucleotides (nts) and begins with the nucleotides for the amino acids RGK.[2] The six nucleotides following the MADS box are "TCTTGC"[2] which may be the additional six needed to get to 180 nts.

"RIN [Ripening Inhibitor] binds to DNA sequences known as the CA/T-rich-G (CArG) box, which is the general target of MADS box proteins (Ito et al., 2008)."[3]

Peaches

"An AGC box (AGCCGCC) was found [from peach (Prunus persica L. Batsch cv. Loring)] between 886 and 892 bp upstream of the translation start site which has been shown in other ethylene-responsive PR genes to be a binding site for ethylene-responsive binding factor proteins (ERF proteins) (Ohme-Takagi and Shinshi, 1995; Sato et al., 1996; Jia and Martin, 1999; Fujimoto et al., 2000)."[4]

"The peach ACO1 does have an AGC box that has been found to bind ethylene responsive elements in response to pathogen infections (Ohme-Takagi et al., 2000; Rushton et al., 2002). Only the apple ACO1 also contains this sequence. In addition, both PpACO1 and the apple ACO1 have a MADS box transcription factor binding site (CarG) (Tilly et al., 1998), but none of the other ACO genes do. "[4]
