High impact information on FAS1

 

Biological context of FAS1

  • The phenotype and allelism indicated that the mutant has a defect in both the FASCIATA1 (FAS1) gene and the FT gene located on the bottom arm of chromosome 1 [5].
  • In order to clarify the implications of CAF-1 in the maintenance of chromatin states in higher eukaryotes, we investigated transcriptional gene silencing (TGS) of various genes in fas mutants [6].
  • Furthermore, TGS of the silent beta-glucuronidase (GUS) transgene was also de-repressed randomly in fas [6].
  • Loss-of-function mutants of CAF-1 in Arabidopsis, fasciata (fas), show a variety of morphological abnormalities and unique defects in gene expression in the meristems [6].
