| Research Abstract |
A fructan exohydrolase gene, Pp6-FEH1 was transcriptionally induced in basal parts of timothy after cutting. This suggests that Pp6-FEH1 is involved in the energy supply for regrowth after cutting. Glucose and sucrose inhibited the up-regulation of Pp6-FEH1 transcripts. Transcriptional induction of Pp6-FEH1 by cold also suggests its involvement in increase of freezing tolerance by producing mono-saccharides known as cryoprotectants. Reporter assay revealed the promoter region involved in the cold induction of timothy FEH.
