Temporal relationship between the transcription of two Arabidopsis MADS box genes and the floral organ identity genes.
MADS box genes play important roles in specifying floral meristem and floral organ identity. We characterized the temporal and spatial expression patterns of two members of this gene family, AGL4 and AGL5 (for AGAMOUS [AG]-like). AGL4 RNA initially accumulates after the onset of expression of the floral meristem identity genes but before the onset of expression of the floral organ identity gene...
متن کاملFunctional conservation of MADS-box factors controlling floral organ identity in rice and Arabidopsis.
Studies on MADS-box genes in Arabidopsis and other higher eudicotyledonous flowering plants have shown that they are key regulators of flower development. Since Arabidopsis and monocotyledonous rice are distantly related plant species it is interesting to investigate whether the floral organ identity factors have been conserved in their functions, and if not, to understand the differences. Arab...
متن کاملThe duplicated B-class MADS-box genes display dualistic characters in orchid floral organ identity and growth.
Orchidaceae are an excellent model to examine perianth development because of their sophisticated floral architecture. In this study, we identified 24 APETALA3 (AP3)-like and 13 PISTILLA (PI)-like genes from 11 species of orchids and characterized them into four AP3- and two PI-duplicated homologs. The first duplication event in AP3 homologs occurring in the early evolutionary history of the Or...

MADS-box genes are involved in floral development and evolution.
MADS-box genes encode transcription factors in all eukaryotic organisms thus far studied. Plant MADS-box proteins contain a DNA-binding (M), an intervening (I), a Keratin-like (K) and a C-terminal C-domain, thus plant MADS-box proteins are of the MIKC type. In higher plants most of the well-characterized genes are involved in floral development. They control the transition from vegetative to ge...
