Numerous TCP genes (transcription factors with a TCP domain) occur in legumes. 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). These genes are therefore particularly interesting in Leg...

Duplication of some floral regulatory genes has occurred repeatedly in angiosperms, whereas others are thought to be single-copy in most lineages. We selected three genes that interact in a pathway regulating floral development conserved among higher tricolpates (LFY/FLO, UFO/FIM, and AP3/DEF) and screened for copy number among families of Lamiales that are closely related to the model species ...

Plant systems in use for the detection of environmental mutagens appear capable of detecting all types of genetic effects which can be studied in animals. The study of somatic mosaicism, however, is better developed in plants than in higher animals. A case is presented here which shows the ability of plant systems in analyzing a host of genetic end points, including chromosome aberrations like ...

Snapdragon (Antirrhinum majus) is one of the most widely cultivated grass flowers in world. WRKY transcription factors, VQ proteins and their interactions play crucial roles plant response to abiotic stresses. However, little known about gene families snapdragon. In present study, genes were comprehensively analyzed snapdragon using bioinformatics approaches, expression drought cold stresses wa...

It is well documented that arbuscular mycorrhizal fungi (AMF) affect growth and nutrient absorption in host plants under pot conditions. However, their effects on reproductive ornamental field conditions are unknown. Our study evaluated the of AMF flowering physiological traits snapdragon (Antirrhinum majus) greenhouse Seedlings were inoculated with Funneliformis mosseae (Nicolson & Gerd.) ...
