Gene expression and enzyme activities of the D-mannose/L-galactose pathway influence L-ascorbic acid content in Myrciaria dubia
(Springer NatureChequia, 2015-12)
The aim of this work was to elucidate the molecular and biochemical mechanisms that control L-ascorbic acid (AsA) content variation in Myrciaria dubia. The AsA was quantified by high-performance liquid chromatography, gene ...
Deficiency of GDP-l-galactose phosphorylase, an enzyme required for ascorbic acid synthesis, reduces tomato fruit yield
(Springer, 2020-01)
Main conclusion: Reduced GDP-l-galactose phosphorylase expression and deficiency of ascorbic acid content lead to decreased fruit set and yield in tomato plants. Abstract: Reduced GDP-l-galactose phosphorylase expression ...
The effect of low ascorbic acid content on tomato fruit ripening
(Springer, 2020-08)
Main conclusion: The oxidant/antioxidant balance affects the ripening time of tomato fruit. Abstract: Ripening of tomato fruit is associated with several modifications such as loss of cell wall firmness and transformation ...
Ethylene signaling triggered by low concentrations of ascorbic acid regulates biomass accumulation in Arabidopsis thaliana
(Elsevier Science Inc, 2018-07)
Ascorbic acid (AA) is a major redox buffer in plant cells. The role of ethylene in the redox signaling pathwaysthat influence photosynthesis and growth was explored in two independent AA deficient Arabidopsis thaliana ...
