Magnesium deficiency induced oxidative stress and antioxidant responses in mulberry plants

Scientia Horticulturae, 2006
Abstract The aim of the study was to implicate induction of oxidative stress and antioxidative responses with the effects of Mg deficiency in mulberry plants. Mulberry (Morus alba L.) cv. Kanva-2 plants grown in hydroponics were subjected to deficiency of Mg.

Correction of magnesium deficiency in tea plants through foliar applications

Communications in Soil Science and Plant Analysis, 1999
Abstract Magnesium (Mg) deficiency observed in tea estates of the Nigerian Beverage Production Company on the Mambilla Plateau of Nigeria resulted in a loss of about 2% of the tea estate including nursery crops and over 40% reduction in quality of made tea.

The response to oxidative stress induced by magnesium deficiency in kidney bean plants

Journal of Plant Biology, 1999
To understand the plant response to oxidative stresses, we studied the influence of magnesium (Mg++) deficiency on the formation of hydrogen peroxide (H2O2), malondialdehyde (MDA), and protease activity in kidney bean plants. The expression pattern of proteins under Mg++ deficiency also was examined via two-dimensional electrophoresis. The formation of

Changes in the Ultrastructure and Respiratory Control of Mitochondria from Maize Plants from Normal Nutrition to Magnesium Deficiency

Biochemie und Physiologie der Pflanzen, 1976
Summary Significant changes take place in both ultrastructure and energetic function of mitochondria from maize plants exhibited to magnesium deficiency. Between the 7th and 19th day after germination the protective mechanism of the oxaleacetic acid comes into action.

Structural and functional disorder in the photosynthetic apparatus of radish plants under magnesium deficiency

Functional Plant Biology, 2018
Magnesium (Mg) is one of the significant macronutrients which is involved in the structural stabilisation of plant tissues and many enzymes such as PSII. The latter efficiency and performance were analysed, using chlorophyll (Chl) a fluorescence induction kinetics and microscopic images, to detect the changes in structure and function of photosynthetic

Leaf diffusional capacity largely contributes to the reduced photosynthesis in rice plants under magnesium deficiency

Plant Physiology and Biochemistry
Numerous studies have clarified the impacts of magnesium (Mg) on leaf photosynthesis from the perspectives of protein synthesis, enzymes activation and carbohydrate partitioning. However, it still remains largely unknown how stomatal and mesophyll conductances (gs and gm, respectively) are regulated by Mg. In the present study, leaf gas exchanges, leaf

Changes in phloem export of sucrose in leaves in response to phosphorus, potassium and magnesium deficiency in bean plants

Journal of Experimental Botany, 1994
The effect of varied phosphorus (10 and 250 mmol P m -3 ), potassium (50 and 2010 mmol K m -3 ) and magnesium (20 and 1000 mmol Mg m -3 ) supply on sucrose, reducing sugars, amino acids, P, K, and Mg in phloem exudate was studied in bean (Phaseolus vulgaris L.) plants over a 12 d growth period in nutrient solution.

Partitioning of shoot and root dry matter and carbohydrates in bean plants suffering from phosphorus, potassium and magnesium deficiency

Journal of Experimental Botany, 1994
The influence of varied supply of phosphorus (10 and 250 mmol P m -3 ), potassium (50 and 2010 mmol K m -3 ) and magnesium (20 and 1000 mmol Mg m -3 ) on the partitioning of dry matter and carbohydrates (reducing sugars, sucrose and starch) between shoots and roots was studied in bean (Phaseolus vulgaris) plants grown in nutrient solution over a 12 d ...

Mechanism of zinc stress on magnesium deficiency in rice plants (Oryza sativa L.): Insights from magnesium isotopes

Science of The Total Environment
Magnesium (Mg) and zinc (Zn) are essential nutrients for plants. Mg deficiency often occurs in rice plants grown in Zn-polluted soil. However, the mechanism for this correlation is unclear. Here, we performed culture experiments on rice plants (Oryza sativa L.) and used Mg isotopes to investigate mechanisms of Zn stress on plant Mg deficiency.

Thermostability of the PYL–PP2C Heterodimer Is Dependent on Magnesium: In Silico Insights into the Link between Heat Stress Response and Magnesium Deficiency in Plants

Journal of Chemical Information and Modeling, 2018
Magnesium deficiency increases the susceptibility of plants toward heat stress. The correlation between magnesium levels and stress response has been studied at the physiological level; albeit, the molecular explanation to this relationship remains elusive.
