“…Down-regulation of SEP1/2 clade genes in tomato, LeTM29 (Ampomah- Dwamena et al 2002), and gerbera, GhGRCD2 (Uimari et al 2004), has produced plants with altered floral organs. In aspen, the lines with suppression of SEP1/2 clade genes, PTM3/4, were indistinguishable from wild-type plants (Cseke et al 2005).…”

“…For example, the ectopic expression of FBP9-like genes of Capsicum (CaMADS1) and of Nicotiana (NsMADS4) produced short, early flowering plants (Sung et al 2001) but no modification in the floral shape in transgenic tobacco (Jang et al 2002). However, Arabidopsis plants that ectopically expressed PTM3/4 of aspen (Cseke et al 2005), or LMADS4 of lily (Tzeng et al 2003), showed no visible phenotypic changes compared to the wild-type plant.…”

SEPALLATA (SEP) MADS box genes play essential and diverse roles in reproductive organ development. To investigate the SEP gene function in peach we isolated three SEP-like genes, PrpMADS2, PrpMADS5, and PrpMADS7, which belong to distinct SEP gene clades. They appeared as single copy genes in the peach genome and were found to preferentially express in flowers and fruits. Arabidopsis transformants expressing 35S: PrpMADS2 were indistinguishable from wild-type plants. Overexpression of PrpMADS5 led to earlier flowering. Through chimeric repressor silencing technology, PrpMADS5 was found to function in floral organ development. Expression of PrpMADS7 in Arabidopsis caused a dramatic attenuation of both juvenile and adult growth phases and, in severely affected plants, it led to flower formation immediately after the embryonic phase. Two microsatellite markers were developed for PrpMADS2 and PrpMADS5 and assigned to the genetic linkage groups 5 and 1, respectively. PrpMADS7, previously identified as PrpAGL2, and PrpMADS5 were identified as potential loci to modify the flowering time and floral organs in Prunus species. Moreover, our results showed the diversification of SEP genes in peach.

Phalaenopsis amabilis (L.) Blume is an indigenous orchid species in Indonesia. This orchid has a white large flower. The large flower is caused by the existence of gene that has an important role in flower development. One of the genes is SEPALLATA 1. This gene is a member of superfamily MADS-Box gene. SEPALLATA 1 gene is a marker of primordial flower organ. This study aimed to isolate SEPALLATA1 gene from Phalaenopsis amabilis (L.) Blume by PCR using forward primer 5'-GCT-GGA-GCG-GAT-CGA-GAA-CA-3'and reverse primer 5'-TCA-TGC-AAG-CCA-ACC-AGG-TG-3'. This study successfully amplified 691 bp lengths of SEPPALATA1 fragment, lacking 20 bp upstream which consist its start codon.

“…The binary vector for over-expression of PTM5 (PTM5 sense) was constructed by inserting a double CaMV 35S/AMV RNA4 promoter, PTM5 coding region (minus the 5′ and 3′ UTRs), and 3′ NOS terminator sequence into the pTCS5 binary vector as previously described (Cseke et al, 2005). pTCS5 has a NPTII/ GUS fusion gene driven by a 35S-promoter for kanamycin selection and GUS reporter expression.…”

“…Our lab has isolated a variety of aspen MADS-box genes that fall within the major phylogenetic classes of MADS-box genes. Most of these genes were shown to be important in the processes of flower formation (Cseke et al, 2003a(Cseke et al, , 2005. However, several MADS-box genes were also identified from developing vascular tissues including the vascular cambium, the secondary meristem responsible for the increase in the girth of stems, branches, and roots.…”
