“…So, there is a large potential for increasing linoleic acid levels. While previous studies on other plant species show that ABA could enhance the accumulation of linoleic acid (Ju et al, 2016;Huo et al, 2020;Norlina et al, 2020), the effect of ABA on oil palm mesocarp is still unknown. Results in this study showed 20 µM ABA was found to significantly promote linoleic acid content in mesocarp compared to an untreated control.…”

“…Exogenous ABA increases levels of palmitic (C16:0) and stearic (C18:0) acids but decreases linoleic (C18:2) and α -linolenic (C18:3n3) acids in Chlorella vulgaris ( Norlina et al, 2020 ). Exogenous ABA can enhance oleic (C18:1) and linoleic acid (C18:2) accumulation in developing Siberian apricot ( Prunus sibirica ) seeds, and ABI3, SAD6, FAD2 , and KCS1-like showed upregulated expressions in ABA treatment compared with control ( Huo et al, 2020 ); it can also enhance the linoleic acid and elaidic acid content in Cabernet Sauvignon ( Vitis vinifera L.) grape berries ( Ju et al, 2016 ). While studies on other plant species show that exogenous ABA influences linoleic acid biosynthesis, this process is still not well understood in oil palm.…”

Abscisic acid plays an important role in fruit development. However, the effect of ABA on fatty acid biosynthesis in oil palm is still unknown. In this study, ABA treatments (CK, A1–A4) were applied to oil palm fruit at 16 WAP (weeks after pollination), and fatty acids in the mesocarp at 24 WAP were analyzed by GC-MS. Results showed that linoleic acid content under treatment A2 (20 μM ABA) was significantly higher (slightly increased by 8.33%) than the control. Therefore, mesocarp samples of A2, and the control at 16, 20, and 24 WAP was sampled for RNA-Seq. KEGG pathway enrichment analysis showed that 43 genes were differentially expressed in the fatty acid biosynthesis pathway, of which expression of EgFAD2 (unigene 105050201) under 20 μM ABA treatment was 1.84-fold higher than in the control at 20 WAP. Further sequence analysis found that unigene 105050201 had more ABA-responsive elements (ABRE), complete conserved domains, and a C-terminal signaling motif among two FAD2 copies. Furthermore, WGCNA and correlation analysis showed co-expression of EgFAD2 (unigene 105050201) with transcription factors (TFs) (WRI1, AP2-EREBP, bZIP, bHLH, C2C2-Dof, MYB, NAC, and WRKY), ABA signaling genes (PYR, PP2C, SnRK, and ABI5), and other genes involved in fatty acid biosynthesis (FATA, FATB, LACS, SAD, Oleosins, and so on). These results indicated that ABA treatment promoted the expression of FAD2 and other genes involved in fatty acid biosynthesis, which possibly resulted in the accumulation of linoleic acid. This study will be helpful for understanding the possible mechanisms through which ABA affects fatty acid biosynthesis and their accumulation in the mesocarp of oil palm.

“…The distribution pattern of phosphocholine was similar to that of PCs, which is likely due to the fact that phosphocholine is a precursor for PC biosynthesis [ 30 ]. Moreover, abscisic acid (ABA) plays a vital role in regulating embryo development and lipid metabolism in seeds [ 31 , 32 ]. The ZH9 and HP peanut had a great abundance of ABA which was distributed mainly in the central part of cotyledons.…”

Peanut (also called groundnut, Arachis hypogaea L.) seeds are used for producing edible oils and functional foods, and offer a rich source of lipids, proteins and carbohydrates. However, the location of these metabolites has not yet been firmly established. In the present study, the matrix-assisted laser desorption/ionization mass spectrometric imaging (MALDI-MSI) technique was applied to investigate spatial distribution of lipids and other key components in seeds of three peanut cultivars (ZH9, KQBH, HP). A total of 103 metabolites, including 34 lipid compounds, were putatively identified by MALDI-MSI. The abundance and spatial distribution of glycerolipids (GLs) and glycerophospholipids (GPs) were compared among the three peanut cultivars. All the identified lysophosphatidylcholine (LPC), phosphatidylethanolamine (PE) and phosphatidylcholines (PCs) were distributed mainly in the inner part of seeds. The visualization of phosphatidic acids (PAs) and triacylglycerols (TGs) revealed a dramatic metabolic heterogeneity between the different tissues making up the seed. The non-homogeneous spatial distribution of metabolites appeared to be related to the different functions of particular tissue regions. These results indicated that MALDI-MSI could be useful for investigating the lipids of foodstuffs from a spatial perspective. The present study may contribute to the development of oil crops with higher oil yields, and to improvement of food processing.

“…For instance, a study shows that crude palm oil has a shelf life of approximately six months [34]. Iodine value is used to determine total unsaturation within the fatty acid which influences the oxidation stability of the oil crop and the produced biodiesel [35][36][37]. Estimation of those properties in an oil crop mixture has been proven to correspond to the mixing ratio of the oil crops used in the biodiesel production [38].…”

A Diverse and Sustainable Biodiesel Supply Chain Optimisation Model Based on Properties Integration

Producing sustainable biodiesel from oil crops has been a great challenge, especially for oil crops plantations that involve various small and medium stakeholders. Differences in plantation activities and environments create a unique sustainability profile for each oil crop that may impose more sustainability issues such as deforestation problems in oil palm plantations. This paper embraced the unique sustainability index profile of each oil crop, and an investigation was performed to evaluate the feasibility of integrating multiple oil crops into the existing biodiesel refinery to improve its economic and sustainability performances. The selection of the process feed is proposed to be based on oil crop properties such as iodine value, peroxide value and saturated and unsaturated fatty acid contents. The sustainability profiles considered in the study include deforestation, oil yield, fertiliser impact, water impact and carbon footprint. Case studies demonstrated that a more balanced sustainability index profile could be achieved at a higher production cost—from USD 6.43 billion·y−1 in a cost-saving-centric solution to USD 39.90 billion·y−1 in a sustainability-improvement-centric solution. The study provided excellent insight into the impact on production cost to achieve sustainability which can help stakeholders to evaluate the feasibility of integrating multiple oil crops in the system.
