Plants invest considerable resources of carbon and calcium in crystal formation indicating that it is an important basic process in growth and development. The diversity of crystal shapes as well as their prevalence and spatial distribution have led to several hypotheses regarding crystal function in plants. The proposed functions include roles in ion balance in plant defense in tissue

C. monogyna ssp. monogyna Jacq. in C. orientalis var. orientalis Pallas ex Bieb. both whewellite and weddelite crystals were found. Although there were some differences among the soluble and insoluble oxalate contents they were

Functions of biominerals may depend on their shape sie abundance placement and chemical composition. In this review we highlight advances in understanding physiological and ecological significance of biomineraliation in plants

Dietary oxalate can contribute considerably to the amount of urinary oxalate excretion. Because cereal foods play an important role in daily nutrition the soluble and total oxalate contents of various types of cereal grains milling products bread pastries

Vitamin C also can get converted into oxalate on getting metabolied . When consumed this oxalate can bind to minerals in the body and form compounds including calcium oxalate and iron
Read MoreIntroduction. The occurrence of calcium oxalate crystals CaC 2 O 4 or CaOx has been observed in plants of several botanical families and they contribute a large portion of the total calcium of these plants.CaOx deposits have been described in most tissues and organs as either intracellular usually associated with vacuoles of specialied cells idioblasts or extracellular deposits

Read MoreThe scattering function of cystoliths and other oxalate druses was already demonstrated for leaves of pecan trees. 3 Here we show that calcium oxalate druses can function as light scatterers even in the case of an annual herbaceous plant. Together all these observations point to the fact that calcium oxalates and cystoliths functioning as light

It is required for various structural roles in the cell wall and membranes it is a countercation for inorganic and organic anions in the vacuole and the cytosolic Ca 2 concentration Ca 2 cyt is an obligate intracellular messenger coordinating responses to numerous developmental cues and environmental challenges

In an attempt to produce ample amounts of oxalate in Arabidopsis two genes from the oxalate biosynthetic operon of B. glumae Nakata and He 2010 were utilied.Both the obcA and obcB genes were inserted behind the 35S Cauliflower mosaic virus CaMV promoter and expressed separately in Arabidopsis
