例文モバイル版携帯版

  • Red and blue light are absorbed through several phytochromes and cryptochromes.
  • Phytochromes are the photoreceptors in a plant that are sensitive to light.
  • Most plants have multiple phytochromes encoded by different genes.
  • Unlike phytochromes and phototropins, cryptochromes are not kinases.
  • Phytochromes B E are more stable with phyB, the main phytochrome in seedlings grown in the light.
  • While all these phytochromes have significantly different protein components, they all use phytochromobilin as their light-absorbing chromophore.
  • Hence maize, for example, has six phytochromes-phyA1, phyA2, phyB1, phyB2, phyC1 and phyC2.
  • Presumably plant phytochromes are derived from an ancestral cyanobacterial phytochrome, perhaps by gene migration from the chloroplast to the nucleus.
  • Subsequently phytochromes have been found in other prokaryotes including " Deinococcus radiodurans " and " Agrobacterium tumefaciens ".
  • Some examples of conjugated proteins are lipoproteins, glycoproteins, phosphoproteins, hemoproteins, flavoproteins, metalloproteins, phytochromes, cytochromes, opsins and chromoproteins.
  • Molecular analyses of phytochrome and phytochrome-like genes in higher plants ( ferns, mosses, algae ) and photosynthetic bacteria have shown that phytochromes evolved from prokaryotic photoreceptors that predated the origin of plants.
  • It is known that although phytochromes are synthesized in the cytosol and the P r form is localized there, the P fr form, when generated by light illumination, is translocated to the cell nucleus.
  • In 1996 a gene in the newly sequenced genome of the cyanobacterium " Synechocystis " was noticed to have a weak similarity to those of plant phytochromes, the first evidence of phytochromes outside the plant kingdom.
  • In 1996 a gene in the newly sequenced genome of the cyanobacterium " Synechocystis " was noticed to have a weak similarity to those of plant phytochromes, the first evidence of phytochromes outside the plant kingdom.
  • Smith is best known for his discovery that phytochromes can detect changes in the colour that plants receive ( e . g ., because of shading from neighbouring plants ), which allows them to adjust their growth rates accordingly.
