abscisic acid, exogenous sucrose, as well as treatments like spikelet thinning, leaf cutting increase enzyme expression and enzyme activity during rice grain filling, determination of protein, overview

effects of hypoxia, anoxia, and submergence on expression of gene sus2 in wild-type and in sus1, sus4, and sus1/sus4 mutants, overview
effects of hypoxia, anoxia, and submergence on expression of gene sus3 in wild-type and in sus1, sus4, and sus1/sus4 mutants, overview
effects of hypoxia, anoxia, and submergence on expression of genes sus1 in wild-type and in sus1, sus4, and sus1/sus4 mutants, overview
effects of hypoxia, anoxia, and submergence on expression of genes sus4 in wild-type and in sus1, sus4, and sus1/sus4 mutants, overview
effects of hypoxia, anoxia, and submergence on expression of genes sus5 in wild-type and in sus1, sus4, and sus1/sus4 mutants, overview
effects of hypoxia, anoxia, and submergence on expression of genes sus6 in wild-type and in sus1, sus4, and sus1/sus4 mutants, overview
enzyme activity increases by 20-200% for 10-20 days of plant growth in presence of (NH4)2SO4 as compared with the roots of plants growing without nitrogen, induction is higher under illumination by sunlight
-
enzymic activity is higher in immature internodes than in mature internodes in all cultivars, sucrose synthase transcript expression shows a similar pattern. Sucrose synthase activity is negatively correlated with sucrose and positively correlated with hexose sugars
expression of isoform SS1 is upregulated by anoxia and by cold temperatures
expression of isoform SS1 is upregulated by anoxia and by cold teperatures
expression of isoform SS3 is upregulated by water deprivation and by cold teperatures
isoform SUS3 is highly expressed during grain filling
-
root restriction treatment increases the enzyme expression, while it reduces cytochrome pathway, and alternative pathway respirations with reduced ATP content. The ratio of invertase/sucrose synthase activity is increased in the restricted roots together with a decrease in glucose content and an increase in fructose content
-
the enzyme activity increases 64.7% during seed development until 28 days after anthesis
-
the enzyme activity is the highest in fruits 44 days after blooming
-
the mRNA expression level of the enzyme is inhibited by abscisic acid or sucrose, but not by glucose after fruit disc incubation in vitro
-
the transcript level and protein abundance of CsSUS3 hardly change during salinity treatment, but the enzyme activity increased slightly, especially on the first and ninth days, compared with control
transcript profiling shows that gene expression of AtSUS1 is upregulated in 3-day-old galls and laser-microdissected giant cells of Meloidogyne javanica
transcript profiling shows that gene expression of AtSUS4 is upregulated in 3-day-old galls and laser-microdissected giant cells of Meloidogyne javanica
under anoxia, the induction of SUS1 is stronger than that of SUS4
when suffering hypoxia stress from flooding, CsSUS3 expression and SUS activity in roots increase, especially in the lateral roots. The soluble SUS activity increases, but the membrane fraction hardly changes. Drought stress modulated by PEG-6000 causes a transient and slight increase in CsSUS3 transcript level on the first and third days, but decreases similarly to control on the sixth and ninth days
