Cattleya alaorii Cattleya alaorii Cattleya alaorii, commonly known as the Laelia alaorii, is a species of orchid endemic to Brazil (Bahia). The species was named after Mr. Alaor Oliveira, former employee at the University of São Paulo at Piracicaba, who first collected this species in a field excursion in the late 1960s. It was discovered in the 1970s in an isolated mountain chain near Itabuna, Bahia state. It grows in the very wet Bahia coastal forests ecoregion of the Atlantic Forest biome ("Mata Atlantica Brasileira"). It is found in rainforests at about above sea level. The plants are epiphytes in tall trees
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
