Cattleya amethystoglossa Cattleya amethystoglossa Cattleya amethystoglossa (the "amethyst-lipped Cattley flower") is a bifoliate species of orchid from the genus "Cattleya". "C. amethystoglossa" is native to Brazil in the states of Bahia and possibly Espirito Santo, where it is found near sea level in close proximity to the Atlantic Ocean. "C. amethystoglossa" grows on palm tree trunks, rock, and large tree branches high in the canopy of evergreen trees. This plant is found growing in bright, airy, humid locations. Its native range has been greatly reduced due to habitat destruction, logging, and agriculture. "C. amethystoglossa" is a tall plant and has pseudobulbs that
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
