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

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 ...

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.

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.

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.

The effects of short-term deficiency of boron on potassium, calcium, and magnesium distribution in leaves and roots of tomato (Lycopersicon esculentum) plants

, 1990
Boron deficiency frequently affects long distance transport of nutrients in plants. In this investigation K, Ca and Mg distributions in shoots and roots of tomato plants under conditions of short-time B deficiency were studied. Plants were grown in water cultures with variation in B supply: 0.0 (−B) and 0.5 (+B)mgL−1. Soluble and insoluble fractions of

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

Antagonistic effects of iron and/or magnesium deficiencies on enzyme activities in lettuce (Lactuca sativaL.) plants

The Journal of Horticultural Science and Biotechnology, 2014
Summary Lactuca sativa L. is one of the most important sources of phytonutrients including vitamins, carotenoids, and antioxidants. However, lettuce growth and quality are strongly affected by soil fertility. In this study, the influence of iron (Fe) and/or magnesium (Mg) deficiencies on the growth, anti-oxidant properties, and ferric chelate reductase
