expression of FEHs following phytohormone treatments, overview. Expression levels of the enzymes involved in fructan breakdown, are determined following pulse treatments with abscisic acid (ABA), auxin (AUX), ethylene (ET), gibberellic acid (GA), or kinetin (KIN) reveals a minor is effect evident for 1-FEH activity with an increased activity in response to KIN and a decrease by GA. LpFEH expression levels are increased 48 h following ET treatment, but this increase is significant only for Lp6-FEH |

several R2R3-MYB transcriptional regulators are analysed for their possible involvement in 1-FEH regulation via transient transactivation of 1-FEH target promoters and for in vivo co-expression with target genes under different stress and hormone treatments, overview |

the profile of water-soluble carbohydrate accumulation and loss is negatively correlated with the mRNA concentration of 1-FEH, especially 1-FEH w3 (1-FEH-6B) |

CiMYB3 and CiMYB5 selectively enhance promoter activities of 1-FEH1, 1-FEH2a, and 1-FEH2b genes, without affecting promoter activities of fructosyltransferase genes. Both factors recognize the MYB-core motifs (C/TNGTTA/G) that are abundantly present in 1-FEH promoters. In chicory hairy root cultures CiMYB5 and CiMYB3 act as positive regulators of the fructan degradation pathway. Expression of 1-FEH1 is potently induced by abscisic acid, iodoacetic acid, and jasmonic acid. Cold exposure caused a substantial upregulation of transcript levels of 1-FEH1 across different plant organs |

In chicory hairy root cultures CiMYB5 and CiMYB3 act as positive regulators of the fructan degradation pathway. Expression of 1-FEH2a is slightly induced by abscisic acid and iodoacetic acid, and more potently induced by jasmonic acid. Cold exposure causes a substantial upregulation of transcript levels of 1-FEH1 across different plant organs |
