Target Genes of the MADS Transcription Factor SEPALLATA3: Integration of Developmental and Hormonal Pathways in the Arabidopsis Flower

Abstract: The molecular mechanisms by which floral homeotic genes act as major developmental switches to specify the identity of floral organs are still largely unknown. Floral homeotic genes encode transcription factors of the MADS-box family, which are supposed to assemble in a combinatorial fashion into organ-specific multimeric protein complexes. Major mediators of protein interactions are MADS-domain proteins of the SEPALLATA subfamily, which play a crucial role in the development of all types of floral organs. In … Show more

“…We find that some directly regulated transcription factors and signaling targets of OsMADS1 are distinct from those of Arabidopsis SEP3. Interestingly, our data also show, in instances, inverse gene expression outcomes for some targets common to OsMADS1 and SEP3 (Kaufmann et al, 2009). Thus, these findings provide insights on how OsMADS1 complexes modulate other transcription factors and the balance between auxin and cytokinin signaling to promote the determinate development of a rice FM.…”

“…8). As homologs of some of these genes in auxin signaling are also direct targets of Arabidopsis SEP3 (Kaufmann et al, 2009;Supplemental Table S7) and we find that OsPIN1 and OsETTIN2 are directly modulated by OsMADS1, we Figure 8. Model depicting the likely mechanism of OsMADS1 action in regulating meristem specification, determinacy, and organ differentiation through different stages of floret development.…”

“…While TFs typically act cooperatively and combinatorially on their cis-regulatory DNA targets for gene expression (Müller, 2001; Levine and Tjian, 2003;Chen and Rajewsky, 2007;Hobert, 2008), a single TF may also target hundreds of genes (Chen and Rajewsky, 2007;Kaufmann et al, 2009;Demura and Ye, 2010;Huang et al, 2012;Li et al, 2012). Many TFs also target their own genes (autoactivation or repression) (Becskei and Serrano, 2000;Wray et al, 2003;Li et al, 2012).…”
