TL;DR: Significant indications are provided that higher-order complex formation is a general and essential molecular mechanism for plant MADS box protein functioning and attribute a pivotal role to the SEP3 'glue' protein in mediating multimerization.

TL;DR: Functional complementation of the sepallata mutant by FBP2 and the finding that theFBP2 protein forms multimeric complexes with other floral homeotic MADS box proteins indicate that FBP 2 represents the same E function as SEP3 in Arabidopsis.

TL;DR: It is concluded that both FBP24 and ABS are necessary to determine the identity of the endothelial layer within the ovule in Arabidopsis and the results presented here demonstrate the importance of the comparative analysis of key regulatory genes in various model systems to fully understand all aspects of plant development.

TL;DR: Four full-length MADS-box cDNAs from chrysanthemum have been isolated and further functionally characterized, and it is concluded that CDM44 is most likely the SEP3 functional equivalent, because theCDM44 protein interacts with CDM proteins of the AP1/FUL and AG subfamilies, and as a higher order complex with the heterodimer between the presumed B-typeCDM proteins.

TL;DR: This approach provides a highly detailed in situ map of MADS domain protein presence during early and later stages of floral development, and shows that the down-regulation of the homeodomain transcription factor WUSCHEL in ovular tissues is preceded by the occurrence of both AGAMOUS and SEPALLATA3 proteins, supporting the hypothesis that both proteins together suppress W USCHEL expression in the ovule.
