Various functions have been attributed to plant crystal idioblasts and crystals. There is evidence that oxalate synthesis is related to ionic balance. Plant crystals thus may be a manifestation of an effort to maintain an ionic equilibrium. In many plants oxalate is metabolized very slowly or not ...
Macronutrient deficiency can be observed either in the lower leaves or upper leaves of the plants depending upon the mobility of the nutrient, which is further controlled by Ca signaling. In this review, we explore the involvement of Ca in nutrient mobilization from old leaves to new leaves, ...
Calcium occurs as a relatively large, divalent ion which readily enters the apoplast and is bound in exchangeable form in cell walls and on the exterior surface of the plasmalemma. It occurs in only very low concentrations in the cytoplasm and chloroplasts and appears to have a limited role as...
It has not been possible to document hyperoxaluria as a result of thiamine deficiency in man, although this vitamin is a cofactor in the conversion of glyoxylate to α-hydroxy-β-ketoadipate. Intake of more than 4 gm/day of ascorbic acid can raise urinary oxalate excretion, but it has not ...
Related to calcium: Calcium deficiencycal·ci·um (kăl′sē-əm) n. Symbol Ca A silvery, moderately hard alkaline-earth metal that constitutes approximately 3.6 percent of the earth's crust and is a basic component of most animals and plants. It occurs naturally in limestone, gypsum, and...
Growth studies were done in defined liquid media to assess effects of Mn toxicity and Ca deficiency associated with soil acidity. The study included 23 str... HH Keyser,DN Munns - 《Soil Science Society of America Journal》 被引量: 259发表: 1979年 Overcoming the Stressful Effects of Salinity...
being activated and propagated throughout the plant body within seconds. This speed likely helps protect the plants from immediate insect attack. Touch triggered a single-peak [Ca2+]cytchange and AP in the rachilla, sequentially inducing [Ca2+]cytincreases at pulvini and subsequent leaflet movements...
21、"There were some proponents of the bigger dairy industry in Laos to improve acalciumdeficiency," says Durst, whose favorite is fried wasp.(德斯特最喜欢的是炸黄蜂,他说:“在老挝,一个较大的乳制品加工厂中有很多人支持改善钙缺乏。”)
Divya Sharma, Anil Kumar, in Calcium Transport Elements in Plants, 2021 18.5.3 Ca2+ ATPases The superfamily of P-type ATPases comprises of calcium pumps (Ca2+ ATPases) that directly utilize ATP as an energy source for ion transport. On the basis of protein sequence identity, two distinct...
In plants, calcium is involved in stress signal transmission and growth. The ultimate goal of this study was to shed light on the mechanisms underlying the effects of exogenous calcium on the mitochondrial antioxidant system, the activity of respiratory metabolism enzymes, and ion transport in ...
