TAILIEUCHUNG - Responses of reactive oxygen species and methylglyoxal metabolisms to magnesiumdeficiency differ greatly among the roots, upper and lower leaves of Citrus sinensis

Magnesium (Mg)-deficiency is one of the most prevalent physiological disorders causing a reduction in Citrus yield and quality. ‘Xuegan’ (Citrus sinensis) seedlings were irrigated for 16 weeks with nutrient solution containing 2 mM (Mg-sufficiency) or 0 mM (Mg-deficiency) Mg(NO3)2. | Responses of reactive oxygen species and methylglyoxal metabolisms to magnesiumdeficiency differ greatly among the roots upper and lower leaves of Citrus sinensis .den color inherit .ttnd ol .ttnd ul .ttnd dl padding 0 0px 0 20px .ttnd hr margin 10px 0px .ttnd a href javascript void 0 .ttnd a href color inherit dtextscript p text-align left dtextscript img vertical-align middle Cai et al.

Xuegan Citrus sinensis seedlings were irrigated for 16 weeks with nutrient solution lt br gt containing 2 mM Mg-sufficiency or 0 mM Mg-deficiency Mg NO3 2. Thereafter we investigated the Mg-deficient lt br gt effects on gas exchange and chlorophyll a fluorescence in the upper and lower leaves and Mg reactive oxygen lt br gt species ROS and methylglyoxal MG metabolisms in the roots lower and upper leaves. The specific objectives lt br gt were to corroborate the hypothesis that the responses of ROS and MG metabolisms to Mg-deficiency were greater lt br gt in the lower leaves than those in the upper leaves and different between the leaves and roots. lt br gt Results Mg level was higher in the Mg-deficient upper leaves than that in the Mg-deficient lower leaves. This lt br gt might be responsible for the Mg-deficiency-induced larger alterations of all the measured parameters in the lower lt br gt leaves than .
