“…Information concerning the evaluation of such differences is scarce, but recent work by Lu et al . () has revealed clear differences in the lipidome of Chlamydomonas nivalis exposed to nitrate or phosphate deprivation. Similarly, the lipid composition of Phaeodactylum tricornutum was differently modified by either nitrate or phosphate deprivation (Abida et al ., ).…”

“…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. Similarly, the lipid composition of Phaeodactylum tricornutum was differently modified by either nitrate or phosphate deprivation (Abida et al, 2015).…”

“…A recent report by Kamalanathan et al (2015) focused on the effect of P on total lipid production by Chlamydomonas reinhardtii and the work by Piepho et al (2010) evaluated phytoplankton P-induced sterol (ST) changes. Specific studies on the influence of P on the microalgal lipid class profile have been particularly scarce since the initial report of Lombardi & Wangersky (1991), with a handful of works in single species (Khozin-Goldberg & Cohen, 2006;Lu et al, 2013;Abida et al, 2015;Maat et al, 2016). Given the vast taxonomic diversity and metabolic differences that exist within eukaryotic phytoplankton, elucidation of lipid responses to P in new microalgal species is crucial for better physiological and biogeochemical understanding of microalgal lipids.…”

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.

Lipids

Lipids are among the most important organic compounds found in all living cells, from primitive archaebacteria to flowering plants or mammalian cells. They form part of cell walls and constitute cell storage material. Their biosynthesis and metabolism play key roles in faraway topics such as biofuel production (third-generation biofuels produced by microorganisms, e.g. algae) and human diseases such as adrenoleukodystrophy, Zellweger syndrome, or Refsum disease. Current lipidomic analysis requires fast and accurate processing of samples and especially their characterization. Because the number of possible lipids and, more specifically, molecular species of lipids is of the order of hundreds to thousands, it is necessary to process huge amounts of data in a short time. There are two basic approaches to lipidomic analysis: shotgun and liquid chromatography-mass spectometry. Both methods have their pros and cons. This review deals with lipidomics not according to the type of ionization or the lipid classes analyzed but according to the types of samples (organisms) under study. Thus, it is divided into lipidomic analysis of archaebacteria, bacteria, yeast, fungi, algae, plants, and animals.
