Advances in Researches on Phytochrome

Abstract

Abstract: The paper has summarized surveys and advances in research on phytochrome since 1920s’ it was discovered, including as follows:(1) Phytochrome plays important roles in the process of plant growth as main photoreceptors which regulate plant growth from seed germination to organ decrepitude;(2)There are five different genotypes of phytochrome, gene homologies and main reaction modes,especially distinguishing on reaction modes of molecular genes PhyA and PhyB of phytochrome; (3)It expatiated physiological functions of phytochromes at biochemistry and molecular level which included regulating on cell developments of phytochromes, how to regulate growth and blossom by regulating photoperiod reactions, gene expression regulations and synergistic effects on plant growth and fertility of phytochrome and plant hormone et cetera;(4)Although people have hardly studied effects on alfalfa fall dormancy of phytochrome and plant hormone so far, this paper brought forward prospects of research at this aspect.
