“…Therefore, it is likely that calcicole species have a tightly controlled or reduced uptake of Ca to survive in calcareous soils (Jefferies and Willis 1964, Raza et al 2000, Valentinuzzi et al 2015. In addition, they may have the capacity for compartmentation and/or physiological inactivation of Ca, such as producing Ca oxalate (Fink 1991, Webb 1999 or Ca sulfate (He et al 2014, Reid et al 2016, excreting Ca salts via stomata, or storing Ca 2+ in leaf glands and trichomes (Silva et al 1996, Charisios et al 2003, Wu et al 2011.…”

Phosphorus (P)-deficiency symptoms are known for Lupinus species grown in calcareous soil, but we do not know if this is due to a high calcium (Ca) availability or a low P availability in the soil. To address this problem, we explored both the effects of Ca and its interactions with P on nutrient status and growth of three Lupinus species. Two Ca-sensitive genotypes (L. angustifolius L. P26723 and L. cosentinii Guss. P27225) and two Ca-tolerant genotypes (L. angustifolius L. cv Mandelup and L. pilosus Murr. P27440) were grown hydroponically at two P (0.1 and 10 μM) and three Ca (0.1, 0.6 and 6 mM) levels. Leaf symptoms and biomass were recorded, whole leaf and root nutrient concentrations were analysed, and leaf cellular P and Ca concentrations were determined. Phosphorus-deficiency symptoms were only observed in the Ca-sensitive genotypes. Among all the genotypes in this study, the Ca-tolerant L. pilosus showed an ability to maintain stable leaf Ca and P concentrations whereas the Ca-tolerant L. angustifolius cv Mandelup did not maintain a stable whole leaf Ca concentration, but maintained a low cytosolic Ca concentration through effective Ca compartmentation. However, the two Ca-sensitive genotypes, L. angustifolius P26723 and L. cosentinii, did not exhibit an ability to maintain a stable whole leaf Ca concentration or effectively compartmentalise Ca. Therefore, having the capacity to maintain a stable whole leaf Ca concentration or effectively compartmentalising Ca in leaves are likely critical for Lupinus species to be Ca tolerant.

“…High Ca 2+ in cytoplasm also precipitates the essential inorganic P, whilst excess rhizospheric Ca 2+ can severely impair photosynthesis and disrupt K + fluxes (Sanders et al 1999). Thus, calcicoles had to develop effective Ca exclusion mechanisms to withstand high Ca 2+ of cytoplasm in the proximity of their roots (Charisios et al 2003). Previous study on tobacco found that it develops a mechanism of metal detoxification by the exudation of metal/Ca-containing particles through leaf trichomes (Harada and Choi 2008).…”

Calcium (Ca) is an important nutrient element for plant growth and development. Nevertheless, excessive Ca restricts plant communities in Carich environments. Lonicera confusa DC. is one species adapted to Ca-rich environments in the karst area of southwest China; however, the anatomical mechanism that allows these plants to respond to a Ca-rich environment remains unclear. L. confusa was cultivated in two types of soil with controlled Ca levels. The ultrastructure of leaves at different developmental stages was observed, and their Ca contents analyzed by laser scanning confocal microscope and energy-dispersive X-ray spectroscopy. There was no significant difference in leaves between the two experimental groups at very early stages of development. The glands of leaves growing in Carich soil became saturated and showed a steady increase of Ca content in the following stages. The Ca level in leaf trichomes also increased steadily, compared with those from Ca-poor soil. When the leaves matured, Ca salts were excreted via stomata of L. confusa from Ca-rich soil. L. confusa had a special anatomical mechanism of responding to Ca-rich environments by excreting Ca salts via stomata, and storing Ca 2+ in leaf glands and trichomes.
