Cattleya iricolor Cattleya iricolor Cattleya iricolor is a species of orchid native to the eastern montane forests of Ecuador and Peru. "Cattleya iricolor" is an epiphytic orchid with slightly compressed pseudobulbs with a single terminal leaf each. The leaves are narrow, up to 35 cm long and 3 cm wide. Flowers are very fragrant, creamy white or yellowish, 8 cm across in size, with long and narrow petals and sepals, pointy lip; up to 6 flowers per pseudobulb. "Cattleya iricolor" grows in Peru and Ecuador in montane forests of the eastern Andes at elevations of ca.1000 m. The conservation status of "Cattleya
Flowering Locus C produce a number of generations during one summer ("summer-annual"), or (b) flower only after vernalization ("winter-annual" or "late-flowering"). This kind of variation can also be provided by variation in the "FRIGIDA" ("FRI") gene. Flowering Locus C Flowering Locus C ("FLC") is a MADS-box gene that in late-flowering ecotypes of the plant "Arabidopsis thaliana" is responsible for vernalization. In a new seedling "FLC" is expressed, which prevents flowering. Upon exposure to cold, less "FLC" is expressed (to a degree depending on the amount of cold), and flowering becomes possible. "FLC" is extensively regulated through epigenetic modifications and transcriptional control. The expression
