High impact information on PHYC

  • Two functionally distinct PHYC haplotype groups are distributed in a latitudinal cline dependent on FRIGIDA, a locus that together with FLOWERING LOCUS C explains a large portion of the variation in A. thaliana flowering time [1].
  • We show that allelic variation at the PHYTOCHROME C (PHYC) photoreceptor locus affects both traits in natural populations of A. thaliana [1].
  • The sos2 mutations, which are recessive, were mapped to the lower arm of chromosome V, approximately 2.3 centimorgans away from the marker PHYC [2].
  • Because the hcf109 locus was mapped at a distance < 0.1 centimorgans from the phytochrome C gene, its molecular characterization by positional cloning is possible [3].
  • The results revealed new details of the tissue-specific expression and light regulation of the PHYC and CRY1 and 2 promoters [4].

Biological context of PHYC

  • Southern analyses indicate that the tomato genome does not contain both a PHYC and a PHYF [5].
  • The Stellaria PHYC contains three long introns within the coding region at conserved locations as in most angiosperm PHY genes [6].
  • Mapping of the transcription start site and 5'-untranslated region of the rice PHYC transcript indicates that it contains an unusually long, intronless, 5'-untranslated leader sequence of 715 bp [7].
  • Genomic mapping shows that the PHYA, PHYB, and PHYC genes are all located on chromosome 3 of rice, in synteny with these genes in linkage group C (sometimes referred to as linkage group A) of sorghum [7].
  • Comparison of genomic and cDNA PHYC sequences shows that the rice PHYC gene contains three introns in the protein-coding region typical of most angiosperm PHY genes, in contrast to Arabidopsis PHYC, which lacks the third intron [7].
