“…The snapdragon gene DEFH49 is expressed mainly in carpels, but also in petals and stamens (Davies and SchwarzSommer, 1994). The OM1 transcript of the orchid Aranda debora was found only in mature flowers (Lu et al, 1993). Six different AGL2-like genes reported from maize (Cacharró n et al, 1995) have diverse expression patterns, ranging from early onset of expression in developing spikelet primordia (ZMM6) to late expression restricted to the developing gynoecial ridge and silk of the female inflorescence (ZMM7).…”

Three MADS-box genes isolated from Monterey pine (Pinus radiata), PrMADS1, PrMADS2, and PrMADS3, are orthologs to members of the AGL2 and AGL6 gene subfamilies in Arabidopsis. These genes were expressed during early stages of pine shoot development in differentiating seed-and pollen-cone buds. Their transcripts were found within a group of cells that formed ovuliferous scale and microsporophyll primordia. Expression of PrMADS3 was also detected in a group of cells giving rise to needle primordia within differentiated vegetative buds, and in needle primordia.

“…In monocotyledonous plants, MADS box genes have been extensively studied, e.g. in maize (Schmidt et al, 1993;Fischer et al, 1995;Mena et al, 1995;Theissen et al, 1995), rice (Chung et al, 1994(Chung et al, , 1995Greco et al, 1997), orchid (Lu et al, 1993), hyacinth (Li et al, 2001(Li et al, , 2002, and wheat (Murai et al, 1997), but not in monocot trees. Palms represent about half of the subclass Arecidae of monocot trees with over 2600 species in the world.…”

Characterization of oil palm MADS box genes in relation to the mantled flower abnormality

In vitro propagation of oil palm (Elaeis guineensis Jacq.) frequently induces a somaclonal variant called 'mantled' abnormality, in which the stamens of both male and female flowers are transformed into carpels. This leads to a reduced yield or complete loss of the harvest of palm oil. The high frequency of the abnormality in independent lines and the high reversal rate suggest that it is due to an epigenetic change. The type of morphological changes suggest that it involves homeotic MADS box genes that regulate the identity of the flower whorls. We have isolated a number of MADS box genes from oil palm inflorescences by a MADS box-directed mRNA display approach. The isolated partial cDNAs included genes that were likely to function at the initial stages of flowering as well as genes that may function in determination of the inflorescence and the identity of the flower whorls. For four genes that were homologous to genes known to affect the reproductive parts of the flower, full length cDNAs were isolated. These were a B-type MADS box gene which may function in the determination of stamen formation, a C-type gene expected to be involved in stamen and carpel formation, and two putative SEP genes which act in concert with the A-, Band C-type MADS box gene in determining flower whorl formation. The B-type gene EgMADS16 was functionally characterized as a PISTILLATA orthologue; it was able to complement an Arabidopsis thaliana pi mutant. Whether EgMADS16, or any of the other EgMADS genes, are functionally involved in the mantled condition remains to be established.

“…In monocots, MADS box genes have been cloned from orchid (Lu et al, 1993), maize (Schmidt et al, 1993), rice (Chung et al, 1994), and sorghum (Greco et al, 1997). However, little is known about the functions of MADS box genes in monocots, although the MADS box genes are believed to play substantial roles on floral organ identity.…”

Polymerase chain reaction (PCR) with degenerate primers was utilized for partial cloning of the MADS box gene family from wheat (Triticum aestivum L.). PCR products corresponding to a part of the MADS box region were cloned and sequenced. Eleven individual clones sequenced were classified into seven types on the basis of the nucleotide sequence and five types on the deduced amino acid sequence, which included two wheat-specific MADS box protein sequences. RT-PCR analysis with degenerate primers revealed preferential expression of the MADS box genes in young spikes. Furthermore, genomic Southern blot analysis with degenerate PCR products as probes indicated that wheat MADS box genes constitute a multigene family and are dispersed throughout the genome.
