“…On the one hand, the vacuolar ion concentration can be increased, and increase the water content to reduce the osmotic pressure of the kernel. On the other hand, cationic transport increased the substance content of kernel, and K, Mn and Cu could promote protein synthesis with providing su cient fatty acid synthase [54,55]. Therefore, increasing the contents of K, Mn and Cu in leaves can increase the contents of palmitic and saturated fatty acid, similar to those previously reported by Cao et al [49].…”

“…The 20 ~ 40 cm soil layer pH had the greatest positive effect on root Cu and Mn contents, root Mn content had the greatest positive effect on leaves K content, Root K content was positive and signi cantly correlated with leaves Cu and Mn contents. Leaves N content had the greatest negative effect on kernel Cu and Mn contents, Leaves Al content had the greatest negative effect on kernel K content, The results indicated that the increase of soil pH promoted the uptake of Cu and Mn elements by C. oleifera roots, which transported from root to leaves through xylem and produces the "Viers effect" with K strongly in uencing by transpiration [54]. Cu and Mn are involved in protein synthesis, and Al can bind to proteins [55].…”

“…Leaves N content had the greatest negative effect on kernel K content, indicating that the increase of soil pH promoted K element absorption in C. oleifera roots, and the K content in organ was constrained by the N content in its upstream organ. It may be that K + is transported in the xylem of plants, which competes for the ion channel with the transport of NO 3 [53,54]. The 20 ~ 40 cm soil layer pH had the greatest positive effect on root Cu and Mn contents, root Mn content had the greatest positive effect on leaves K content, Root K content was positive and signi cantly correlated with leaves Cu and Mn contents.…”

Background Most of C. oleifera forests have low yield and poor quality, largely associating with soil fertility. Soil physical and chemical properties interact with each other to affect soil fertility. C. oleifera growing under different soil conditions affected their yield and oil composition. Three main soil types were selected, and redundancy, correlation, and double-screening stepwise regression analysis were used, for exploring the relationships between Camellia oleifera nutrients uptake and soil physical and chemical properties, shedding light on the transport law of nutrient elements from root, leaves, and kernel, and elaborating the regulation of fruit yield and oil composition. Results In the present study, available soil elements content of C. oleifera forest were mainly regulated by water content, pH value total N, P and Fe contents. Seven elements (N, P, K, Mg, Cu, Mn and C) were key for kernel’s growth and development, with N, P, K, Cu and Mn contents determining the yield traits. The transport characteristics of these nutrients from root, leaves to the kernel were synergistic and antagonistic effects. There were two ways to control the oil production and the content of various oil components: one was to adjust N, P, K, Mg, Zn, Fe and Cu contents of leaves by applying corresponding foliar fertilizers, while the other was to change the soil water content and pH, and apply N, P, Zn, Mg and Ca fertilizers. Conclusion Soil type controlled nutrient absorption by soil pH, water content and total N, P and Fe content. There were synergistic and antagonistic effects on the inter-organ transport of nutrient elements, ultimately affecting the contents of N, P, K, Cu and Mn in kernel, which determined the yield and oil composition of C. oleifera.

Seven elements (N, P, K, Mg, Cu, Mn and C) were key for kernel’s growth and development, with N, P, K, Cu and Mn contents determining 74.0% the yield traits. The transport characteristics of these nutrients from root, leaves to the kernel had synergistic and antagonistic effects. Increasing oil production and unsaturated fatty acid content can be accomplished in two ways: one through increasing N, P, Mg, and Zn contents of leaves by applying corresponding N, P, Mg, Zn foliar fertilizers, while the other through maintaining proper soil moisture content by applying Zn fertilizer in the surface layer and Mg and Ca fertilizer in deep gully. Conclusion Soil type controlled nutrient absorption by soil pH, water content and total N, P and Fe content. There were synergistic and antagonistic effects on the inter-organ transport of nutrient elements, ultimately affecting N, P, K, Cu and Mn contents in kernel, which determined the yield and oil composition of C. oleifera.

Augmenting salt tolerance in rice by regulating uptake and tissue specific accumulation of Na⁺‐ through Ca²⁺‐induced alteration of biochemical events

The protective effect of Ca 2+ against NaCl toxicity was investigated in two rice varieties with contrasting for salt tolerance to understand the mechanistic details of the antagonism to address adverse effects of salinity on agriculture.• The study primarily examined the influence of Ca 2+ on expression/activity of the effectors and regulators involved in Na + translocation.• Calcium reduced uptake of Na + concomitant with higher tissue K + /Na + in seedlings, comparatively more in salt-tolerant Nona Bokra than in salt-sensitive IR-64, together with a significant increase in root PM H + ATPase in the former, but not in the latter. Increased antagonism in Nona Bokra could be the result of Ca 2+ signalling-mediated phosphorylation of PM H + ATPase in roots caused by a significant Ca 2+ -dependent increase in expression of OsCIPK24, which did not occur in IR-64. Furthermore, significant Ca 2+ -mediated NaCl-induced increase in transcription of 14-3-3 protein in Nona Bokra, but not in IR-64, might also lead to a greater protective effect of Ca 2+ in the former, as 14-3-3 protein is essential for activating PM H + ATPase.• Thus, efficient functioning of PM H + ATPase could be key in determining resistance of plants to salinity, implying that identification of the Ca 2+ -dependent kinase phosphorylating the PM H + ATPase threonine residue and manipulation of its expression, together with expression of 14-3-3 proteins could be an important strategy to improve salt tolerance of crops and their cultivation in salt-affected lands.
