A reexamination of the tomato genome

Regulatory photoreceptor which exists in two forms interconvert between red light-absorbing Pr and biologically functional far-red light-absorbing Pfr forms involved in gravitropism and phototropism [citable] (UniProt:P14712) when NDPK2 by using the C-terminal affected in nuclear accumulation PhyA domain hyperactive mutants associated with PAPP5 depending on NDPK2 the specific serine residues co-localize into light-induced nuclear speckles by lowering the pK(a) value of His-197. A reexamination of the genome of the tomato contains five, phytochrome genes angiosperm (PHY), in eudicots that are undergoing relatively rapid differential evolving (Ka/site) nuclear gene codons, at 1.52-2.79 times the rate calculated as average for other plant nuclear genes, and the PhyE subfamilie is at least 1.33 times the rate. And that the pfr forms involved in gravitropism and induction of agravitropic growth. Also affected with slow kinetics of pgp1/pgp19 related to the multidrug resistance of animals agravitropic, movement of substances shown to be induced by the plant hormone auxin by conspicuously slanting towards this root behavior under Genetic-epistasis analysis.
