L-Ascorbic acid-l-11C and its oxidation product, dehydro-L-ascorbic acid, produced labeled oxalic acid in oxalateaccumulating plants such as spinach seedlings (Spinacia oleracea) and the detached leaves of woodsorrel (Oxalis stricta and 0. oregana), shamrock (Oxalis adenopylla), and begonia (Begonia evansiana). In 0. oregana, conversion occurred equally well in the presence or absenice of light.

This observation has been extended by the present study to oxalateaccumulating plants. MATERIALS AND METHODSSpinach seedlings (Spinacia oleracea, var. Bloomsdale) were grown under greenhouse conditions in a vermiculite-pearlite mixture. Twelve-day-old seedlings were detached from their roots and placed in vials containing the radioactive solution as described in earlier studies (27)

“…Oxalic acid accumulates in certain species of plants such as spinach, woodsorrel, and begonia (6,10,12,23,24,26). Its formation has been attributed variously to carbohydrate metabolism, interconversions of components in the tricarboxylic acid cycle, glycolate metabolism, and pyruvate metabolism (23).…”

“…Many nonvascular plants, especially marine algae and certain fungi, produce mineralized tissues or mineralized cells. Some lichens may have as much as 66% of their dry weight formed by calcium oxalate (10), and some algae as much as 85% dry weight formed by calcium carbonate (27). The general conclusion that mineralized tissues are common in plants is sound.…”

Three Systems of Biomineralization in Plants with Comments on the Associated Organic Matrix

Biological Mineralization and Demineralization

Abstract. Three systems of biomineralization are common in higher plants. The formation of intracellular deposits of crystalline calcium oxalate takes place in a crystal vacuole. The individual crystal (one to many) develops within a crystal chamber bounded by a membrane and is often associated wi th tubules and membranes in the crystal vacuole. Other than the presence of pOlysaccharide and protein, the chemical nature of these elements is not well established. Exactly which elements constitute an organic matrix is not clear.In the formation of calcium carbonate in cystoliths, however, the structure that constitutes the organic matrix is clear. The carbonate is deposited in association with a siliconized cellulose and callose framework.

Solche Untersuchungen von Weinbeeren haben unvermeidlich den Fehler, daß unreifes und reifes Material nicht gleichzeitig verglichen werden kann.…”
