High impact information on Antirrhinum

  • The PHANTASTICA gene encodes a MYB transcription factor involved in growth and dorsoventrality of lateral organs in Antirrhinum [1].
  • The 2959 bp HFL1 sequence predicts a 2.0 kb open reading frame (ORF1) with substantial amino acid similarity to the transposases of Activator (Ac) from maize (Zea mays) and Tam3 from snapdragon (Antirrhinum majus) [2].
  • AS1 encodes a myb domain protein, closely related to PHANTASTICA in Antirrhinum and ROUGH SHEATH2 in maize, both of which negatively regulate knotted-class homeobox genes [3].
  • In two mutants in distantly related species, terminal flower 1 in Arabidopsis and centroradialis in Antirrhinum, inflorescences that are normally indeterminate are converted to a determinate architecture [4].
  • Dorsoventral asymmetry of the Antirrhinum corolla depends on expression of the CYC and DICH genes in dorsal petals [5].

Associations of Antirrhinum with chemical compounds

  • Niv-525 is a semi-dominant allele of the nivea locus, which encodes the enzyme chalcone synthase required for flower pigment biosynthesis in Antirrhinum majus [12].
  • The benzenoid ester, methylbenzoate is one of the most abundant scent compounds detected in the majority of snapdragon (Antirrhinum majus) varieties [13].
  • Aureusidin synthase, a polyphenol oxidase (PPO), specifically catalyzes the oxidative formation of aurones from chalcones, which are plant flavonoids, and is responsible for the yellow coloration of snapdragon (Antirrhinum majus) flowers [14].
  • Expression of an Antirrhinum dihydroflavonol reductase gene results in changes in condensed tannin structure and accumulation in root cultures of Lotus corniculatus (bird's foot trefoil) [15].
  • The same result was obtained with a UF3GT from Antirrhinum majus and a flavonol 4'-O-glucosyltransferase from Allium cepa [16].
 

Gene context of Antirrhinum

  • Genes of this class in Arabidopsis (TCP1) and snapdragon (Antirrhinum majus; CYCLOIDEA) have been shown to be asymmetrically expressed in developing floral primordia, and in snapdragon, they are required for floral zygomorphy (bilaterally symmetrical flowers) [17].
  • The UFO gene shows extensive homology with FIMBRIATA (FIM), a gene mediating between meristem and organ identity genes in Antirrhinum [18].
  • It has previously been proposed for Antirrhinum that another gene, FIMBRIATA (FIM), mediates between the LFY and AP3 orthologs, with the three genes acting in a simple regulatory hierarchy [19].
  • Analysis of the transcription factor WUSCHEL and its functional homologue in antirrhinum reveals a potential mechanism for their roles in meristem maintenance [20].
  • As a first step in exploring their function in plants, we isolated four cdc2-related genes from Antirrhinum [21].
