“…Two MADS-box genes DEFICIENS (DEF) of Antirrhinum majus (Schwarz-Sommer et al 1990) and AGAMOUS of A. thaliana (Yanofsky et al 1990) play important roles in flower development. In addition to floral morphogenesis, MADS-box genes have also been proposed to be involved in vegetative development (Rounsley et al 1995;Heard et al 1997;Carmona et al 1998;GarciaMaroto et al 2002;Montiel et al 2004). For instance, POTM1 (MADS-box 1) of potato (Kang and Hannapel 1996) regulates the transitional phase from vegetative meristem to inflorescence meristem (Hart and Hannapel, 2002).…”

“…In contrast, potato STMADS11 and STMADS16 (Carmona et al 1998;Garcia-Maroto et al 2000) are involved in promoting vegetative growth. Similarly, AGL17 (Agamous-like 17) subfamily members, including NMHC5, DEFH125, ANR1, AGL16, AGL17, and AGL21 (Rounsley et al 1995;Heard et al 1997;Zhang and Forde 1998;Alvarez-Buylla et al 2000;Burgeff et al 2002), are also related to vegetative morphogenesis. Thus, MADS-box transcription factors appear to participate in divergent functions.…”

Storage root formation and development in sweet potato [Ipomoea batatas (L) Lam. Convolvulaceae] is a complex process characterized by the cessation of root elongation, genesis of vascular cambium, anomalous and interstitial cambia, and increase in radial growth by increased cell proliferation and expansion concomitant with the massive deposition of starch and storage proteins that eventually result in storage root enlargement. Phytohormones play a crucial role in the formation of storage roots. Three class I knotted-like homeobox (KNOX1) genes-SRF1, SRF5, and SRF6-modulate carbohydrate metabolism and cell division. The genes Ibkn1 and Ibkn2 activate cytokinin biosynthesis. Transcription factors derived from MADS box genes IbMADS1, IbMADS3, IbMADS4, and IbAGL17 induce signal transduction pathway leading to storage root formation and development. The occurrence of SRD1 transcripts mainly in the actively dividing cells, including the vascular and cambium cells, and the increase in endogenous indole-3-acetic acid (IAA) content and three auxin-inducible AUX/IAA gene transcripts concomitantly with SRD1 transcripts suggest the involvement of SRD1 during the early stage of storage root development. Along with IbMADS1 induction, two storage root marker genes, which encode a major storage protein sporamin and IbAGPase that encodes AGPase for ADP-glucose production in starch biosynthesis, are up-regulated during the early period of storage root development. A class III HD-Zip protein 8 regulating the development of cambia and secondary vascular tissues, a short-root protein that is a key regulator in root 157 radial patterning, meristem maintenance, and asymmetric cell division, the expansin gene IbEXP1 encoding a cell wall loosening protein, genes encoding cyclin A-and cyclin D-like proteins, and five cyclin-dependent kinases are upregulated during storage root formation. Genes encoding ADP-glucose pyrophosphorylase, granule-bound starch synthase, starch synthase, and phosphoglucomutase are up-regulated, whereas genes encoding pyruvate decarboxylase and lactate dehydrogenase are down-regulated during storage root development. The endogenous sucrose levels influence the expression of two AGPase isoforms: ibAGP1 and ibAGP2. The expression of cell wall-bound (extracellular/apoplast) acid invertase activity gene (cwINV) predominates during early period, whereas the expression of cytosolic activity of sucrose synthase gene (SuSy) predominates during later period of storage root enlargement. The competition between lignification and formation of anomalous cambia and the associated starchaccumulating cells determine storage root development. Genes encoding enzymes such as coumaroyl-CoA synthase, caffeoyl-CoA O-methyltransferase, and cinnamyl alcohol dehydrogenase during storage root formation reduce lignification in tissue sections of storage roots.

“…SHP1 and SHP2 are expressed in the ovules and in the developing pistil and fruit, where they share largely redundant functions in specifying the fruit dehiscence zone required for seed-pod shattering, by controlling the formation of specialized valve margin cells that are found only in fruits of the Brassicaceae (Liljegren et al, 2000). STK is expressed in the developing ovule primordia and seeds and functions in specifying ovule identity (D function) along with the AG and SHP1/SHP2 genes (Rounsley et al, 1995;Favaro et al, 2003;Pinyopich et al, 2003). Remarkably, in a demonstration of how gene function can be unpredictably partitioned between products of a gene-duplication event, AG and PLENA (PLE ), its functional counterpart in Antirrhinum, respectively, belong to the paralogous euAG and PLENA lineages that descended from the core eudicot duplication event.…”

“…For example, those which are expressed in primordia of the three inner whorls of flowers might mediate between floral meristem and organ identity genes (Pnueli et al 1994a;Angenent et al 1994;Savidge et al 1995). Moreover, the expression patterns of several MADS-box genes suggest that they might be involved in vegetative growth, root or fruit development, or embryogenesis (Ma et al 1991;Mandel et al 1994;Shore and Sharrocks 1995;Davies and Schwarz-Sommer 1994;Pnueli et al 1991;Flanagan and Ma 1994;Rounsley et al 1995;Heck et al 1995).…”

Classification and phylogeny of the MADS-box multigene family suggest defined roles of MADS-box gene subfamilies in the morphological evolution of eukaryotes

The MADS-box encodes a novel type of DNA-binding domain found so far in a diverse group of transcription factors from yeast, animals, and seed plants. Here, our first aim was to evaluate the primary structure of the MADS-box. Compilation of the 107 currently available MADS-domain sequences resulted in a signature which can strictly discriminate between genes possessing or lacking a MADS-domain and allowed a classification of MADS-domain proteins into several distinct subfamilies. A comprehensive phylogenetic analysis of known eukaryotic MADS-box genes, which is the first comprising animal as well as fungal and plant homologs, showed that the vast majority of subfamily members appear on distinct subtrees of phylogenetic trees, suggesting that subfamilies represent monophyletic gene clades and providing the proposed classification scheme with a sound evolutionary basis. A reconstruction of the history of the MADS-box gene subfamilies based on the taxonomic distribution of contemporary subfamily members revealed that each subfamily comprises highly conserved putative orthologs and recent paralogs. Some subfamilies must be very old (1,000 MY or more), while others are more recent. In general, subfamily members tend to share highly similar sequences, expression patterns, and related functions. The defined species distribution, specific function, and strong evolutionary conservation of the members of most subfamilies suggest that the establishment of different subfamilies was followed by rapid fixation and was thus highly advantageous during eukaryotic evolution. These gene subfamilies may have been essential prerequisites for the establishment of several complex eukaryotic body structures, such as muscles in animals and certain reproductive structures in higher plants, and of some signal transduction pathways. Phylogenetic trees indicate that after establishment of different subfamilies, additional gene duplications led to a further increase in the number of MADS-box genes. However, several molecular mechanisms of MADS-box gene diversification were used to a quite different extent during animal and plant evolution. Known plant MADS-domain sequences diverged much faster than those of animals, and gene duplication and sequence diversification were extensively used for the creation of new genes during plant evolution, resulting in a relatively large number of interacting genes. In contrast, the available data on animal genes suggest that increase in gene number was only moderate in the lineage leading to mammals, but in the case of MEF2-like gene products, heterodimerization between different splice variants may have increased the combinatorial possibilities of interactions considerably. These observations demonstrate that in metazoan and plant evolution, increased combinatorial possibilities of MADS-box gene product interactions correlated with the evolution of increasingly complex body plans.
