Uniprot | TISSUE SPECIFICITY: Isoform 1 is specifically expressed in flowers, mostly in petals, inflorescence and flower buds. Isoform 2 is expressed ubiquitously (leaves, flowers and stems). {ECO:0000269|PubMed:16902407}. |

Description |
TAIR | A basic helix-loop-helix encoding gene (BIGPETAL, BPE) involved in the control of petal size. BPE is expressed via two mRNAs derived from an alternative splicing event. The BPEub (AT1G59640.1)transcript is expressed ubiquitously, whereas the BPEp (AT1G59640.2) transcript is preferentially expressed in petals. Plants that lack the petal-expressed variant BPEp have larger petals as a result of increased cell size. BPEp is positively regulated downstream of APETALA3, PISTILLATA, APETALA1 and PISTILLATA3 and is negatively regulated downstream of AGAMOUS. |
UniProt | Involved in the control of petal size, by interfering with postmitotic cell expansion to limit final petal cell size. {ECO:0000269|PubMed:16902407}. |

- BIGPETALp (BPEp)acts downstream of petal organ identity genes and regulates the size of A. thaliana petals by restricting cell expansion. [BIGPETAL] [BPE]
[PMID: 16902407] - BPEp acts downstream of OPR3 in the jasmonate biosynthesis pathway. Jasmonate regulates BPEp expression at the post-transcriptional level.
[PMID: 19765234] - The physical and genetic interactions between BPEp and ARF8 suggest that BPEp function likely affects auxin-mediated gene responses.
