Phenotype
accumulation of anthocyanins (purple colouration) in cotyledons of developing embryos; dark-grown seedlings resemble light-grown wild-type seedlings having short hypocotyl, open and enlarged cotyledons, accumulation of anthocyanins, chloroplast-like plastid differentiation; expression of light-induced genes in dark-grown plants; light-grown seedlings are heavily pigmented, with anthocyanin accumulation even in roots, open cotyledons, shoots are small and abnormally shaped, lethal (development arrested soon after initiation of primary leaves); maintained as heterozygote; Blue-light- or dark-grown mutants contain high levels of anthocyanins and are not responsive to cytokinins. Vandenbussche, et al. (2007)<p>Both dark- and light-grown homozygous mutant seedlings are severely retarded in their development, with significantly reduced cell elongation in their hypocotyls and reduced cell enlargement in their cotyledons. Both mature seeds and seedlings homozygous for the mutations exhibit dark purple coloration in their hypocotyls and cotyledons due to high levels of anthocyanin accumulation. Most important, homozygous mutants are adult lethal. Occasionally, some mutant individuals will develop up to three pairs of tiny true leaves before senescence. Not a single mutant plant has been able to survive to reproduce.
