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 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 of "FLC" is affected by other genes including "FLK", "FCA" and "VERNALIZATION2" ("VRN2"). Wild "Arabidopsis" plants have different alleles for the "FLC" gene, which correspond to ecotypes which either (a) flower rapidly and
