LITERATURE
0.01 mM abscisic acid upregulates enzyme expression in petiole and leaf 10-24 h after treatment. Prolonged abscisic acid treatment to 72 h causes an induction of enzyme expression also in taproot. The enzyme expression is also upregulated 10 days after nitrogen starvation in all three organs
-
0.2 mM jasmonic acid methyl ester induces a 85fold accumulation of fructooligosaccharide (FOS) in the stems of Agave inaequidens. Significant FOS accumulation in this species also occurs in response to treatments with 1 mM salicylic acid, 8% sucrose, and 10% polyethylene glycol
-
elicitors such as salicylic acid and jasmonic acid methyl ester have a strong effect on fructooligosaccharide (FOS) accumulation. Exogenous application of 1 mM salicylic acid induces a 36fold accumulation of FOS of various degrees of polymerization in stems. 50 mM abscisic acid, 8% sucrose, and 1.0 mg/L kinetin also lead to a significant accumulation of low and high degrees of polymerization FOS in this species
enzyme expression is reduced under 0.1 mM 1-aminoyclopropane-1-carboxylic acid and cold (6°C) treatment
-
expression of 1-FFT is strongly induced upon transfer to high-carbon/low-nitrogen medium, limiting nitrogen supply by lowering KNO3 and (NH4)2SO4 concentrations to 5 and 0.2 mM, respectively, under an elevated sucrose concentration (6%), results in a strong increase in transcript level for 1-FFT, 1-FFT expression is transiently and only moderately induced during the first 24 h of cold exposure
-
increasing the carbon availability by increasing the sucrose concentration from 3 to 6% (w/v) does not result in sustained 1-FFT induction, LY-294002 does not affect the induction of 1-FFT expression
-
the enzyme activity in harvested tubers continuously decreases from 30 to 70 days after flowering. During storage of the tubers, a gradual decrease in enzyme activity takes placed
-
there is an increase in the enzyme activity in a drought-tolerant wheat cultivar exposed to drought stress for 7 days by water cessation
-
treatment with the calcium channel blocker LaCl3 prevents the induction of 1-FFT, the calmodulin antagonist W7 decreases the induction of 1-FFT, genistein and staurosporine reduce the expression of 1-FFT, endothal and cantharidin strongly repress the induction of 1-FFT in a very similar manner
