LITERATURE
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). Lp6-FEH level is increased 48 h following ABA treatment. LpFEH expression levels are increased 48 h following ET treatment, but this increase is significant only for Lp6-FEH. Lp6-FEH expression is increased 24 and 48 h (significant) following AUX and KIN treatment compared to the corresponding controls
for variety DH 338, under the drought treatment 1-FEH and 6-FEH activity increases are much less pronounced but increase strongly in the well-watered plants
in the stubble of seedlings and in young haplocorms from adult timothy plants, transcripts of 6-FEH1 are significantly increased (about 7fold) within 3 h of defoliation, followed by an increase in fructan 6-exohydrolase activity
the transcript levels of 6-FEH increase with decrease in ambient temperatures and the levels decrease under snow in snow mold-resistant cultivars
Wfh-sm3 transcripts increase in wheat leaf tissues inoculated with snow mold and incubated under snow cover
