“…A; Broadley et al ), which is similar to the maximum critical organic‐N: critical P concentration ratio determined for a range of crop species (Greenwood et al ) and is consistent with a protein:RNA ratio of about 15 (assuming ratios of ester‐P: nucleic acid P:lipid‐P:inorganic‐P of 1:2:1.3:1.4, Veneklaas et al ). Differences in foliar N:P ratios of plants with balanced growth are generally related to differences in leaf P concentrations, rather than leaf N concentrations (Sterner and Elser , Raven ). Since growth rates of organisms are positively correlated with rRNA abundance, greater foliar P concentrations are generally associated with greater growth rates and, through this, ecological strategy (Sterner and Elser , Niklas , Raven ).…”

The ionome is defined as the elemental composition of a subcellular structure, cell, tissue, organ or organism. The subset of the ionome comprising mineral nutrients is termed the functional ionome. A ‘standard functional ionome’ of leaves of an ‘average’ angiosperm, defined as the nutrient composition of leaves when growth is not limited by mineral nutrients, is presented and can be used to compare the effects of environment and genetics on plant nutrition. The leaf ionome of a plant is influenced by interactions between its environment and genetics. Examples of the effects of the environment on the leaf ionome are presented and the consequences of nutrient deficiencies on the leaf ionome are described. The physiological reasons for (1) allometric relationships between leaf nitrogen and phosphorus concentrations and (2) linear relationships between leaf calcium and magnesium concentrations are explained. It is noted that strong phylogenetic effects on the mineral composition of leaves of angiosperm species are observed even when sampled from diverse environments. The evolutionary origins of traits including (1) the small calcium concentrations of Poales leaves, (2) the large magnesium concentrations of Caryophyllales leaves and (3) the large sulphur concentrations of Brassicales leaves are traced using phylogenetic relationships among angiosperm orders, families and genera. The rare evolution of hyperaccumulation of toxic elements in leaves of angiosperms is also described. Consequences of variation in the leaf ionome for ecology, mineral cycling in the environment, strategies for phytoremediation of contaminated land, sustainable agriculture and the nutrition of livestock and humans are discussed.

“…By contrast, far fewer studies have been devoted to assessing the effects of phosphorus (P) on lipid composition and metabolism in microalgae. Different physiological responses can be expected in phytoplankton as a result of differences in either N or P resource availability (Raven, 2015), and such differences can also be expected in the lipid composition of microalgae. Information concerning the evaluation of such differences is scarce, but recent work by Lu et al (2013) has revealed clear differences in the lipidome of Chlamydomonas nivalis exposed to nitrate or phosphate deprivation.…”

Interspecific variability in phosphorus‐induced lipid remodelling among marine eukaryotic phytoplankton

The response of marine microalgal lipids to phosphorus is of central importance in phytoplankton ecology but remains poorly understood. We determined how taxonomically diverse microalgal species remodelled their lipid class profile in response to phosphorus availability and whether these changes coincided with those already known to occur in land plants and in the limited number of phytoplankton species for which data are available. The complete lipid class profile and specific lipid ratios influenced by phosphorus availability were quantified in two green microalgae and seven Chromalveolates exposed to phosphorus repletion, deprivation and replenishment. Lipid class cell quota changes in the two green microalgae resembled the currently described pattern of betaine lipids substituting for phospholipids under phosphorus depletion, whereas only two of the studied Chromalveolates showed this pattern. Sulpholipids counterbalanced phosphatidylglycerol only in Picochlorum atomus. In all other species, both lipids decreased simultaneously under phosphorus deprivation, although sulpholipids declined more slowly. Phosphorus deprivation always induced a decrease in digalactosyl-diacylglycerol. However, the ratio of digalactosyl-diacylglycerol to total phospholipids increased in eight species and remained unchanged in Isochrysis galbana. Marine phytoplankton seems to have evolved a diversified mechanism for remodelling its lipid class profile under the influence of phosphorus, with cryptophytes and particularly haptophytes exhibiting previously unobserved lipid responses to phosphorus.

“…Indonesia is an archipelagic country, having the second longest shoreline in the world after Canada according to various data from the internet. The length of Indonesia's shoreline is 106,000 km, and the area of its sea is 5.8 million km 2 . Approximately 1,060,000 ha of land along the shoreline had the potential to be utilized for agriculture.…”

“…In addition to N., the availability of P in soil is also important because legumes are more responsive to P [1]. Phosphorus plays important roles in energy transfer within plant cells, and it can improve the effectiveness of the N function, and the efficiency of N uses [2].…”

Indonesia is an archipelagic country, having vast coastal areas which have not been utilized optimally for crop cultivation because their poor soil properties become a limiting factor for plant growth. It is, therefore, necessary to use cultivation technology, such as the use of biofertilizers to overcome this limiting factor. The objective of this study was to determine the appropriate biofertilizers for improving the quality of soybean seeds, the rhizosphere environment, and the soybean yield in a coastal area. The study was conducted in Bengkulu, Indonesia, using Randomized Complete Block Design, with a single factor, namely biofertilizers. Six treatments were applied, namely the addition of Arbuscular Mycorrhizal Fungi (AMF), phosphate-solubilizing fungi (PSF), Rhizobium (R), AMF+PSF, R+AMF, and R+PSF. The results of this study showed that, in general, the inoculation of biofertilizers could increase the yield of soybeans in the coastal area, as indicated by the higher yield of plants in this study than those as described in the literature. The dual inoculation of PSF+AMF resulted in the highest protein content, the largest populations of PSF and AMF, the highest percentage of root colonization of AMF, plant phosphorus concentration and absorption, the weight of seeds per plant and yield. Meanwhile, the highest fat content of seed was found in the plants inoculated with PSF. In coastal soil, the dual application of biofertilizers, namely PSF and AMF, should be done, instead of a single application. Further studies are needed to increase the protein content and to reduce the fat content of soybean seeds.
