Murici Ecological Station an average of . The dominant vegetation is dense rainforest in the Atlantic Forest biome. In the best preserved areas, mostly at the higher elevations, the forest forms a fairly uniform closed canopy up to high that provides shade and retains moisture. Tree species include murici ("Byrsonima sericea"), "Schefflera morototoni", "Parkia pendula", "Tabebuia" species, "Pseudobombax" species, "Bowdichia virgilioides", "Tapirira guianensis", "Handroanthus impetiginosus" and "Protium" species. The understory contains seedlings of trees, palms such as "Euterpe catinga", and many lianas and epiphytes, such as "Araceae", "Orchidaceae" ("dimerandra" species, "Dichaea" species, "Rodriguezia" species, "Cattleya labiata", "Pleurothallis" species, "Epidendrum" species, "Oncidium" species and
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
