“…Inhibition of the expression of the endogenous GmPEPC gene in soybean promoted the accumulation of oil, while the increase in PEPC activity favored the synthesis of protein (Zhang et al 2017;Zhao et al 2006). Transcription factors GmDof4 and GmDof11 increased the oil content in grains by activating the expression of fatty acid synthesisrelated genes such as acetyl-CoA carboxylase gene and by inhibiting the expression of protein synthesis-related genes (Wang et al 2007;Sun et al 2018). The ABI3 (Abscisic acid insensitive 3) gene is involved in regulating the synthetic pathways of both protein and oil (Lazarova et al 2002).…”

Key message Genetic resources contributes to the sustainable protein production in soybean. Abstract Soybean is an important crop for food, oil, and forage and is the main source of edible vegetable oil and vegetable protein. It plays an important role in maintaining balanced dietary nutrients for human health. The soybean protein content is a quantitative trait mainly controlled by gene additive effects and is usually negatively correlated with agronomic traits such as the oil content and yield. The selection of soybean varieties with high protein content and high yield to secure sustainable protein production is one of the difficulties in soybean breeding. The abundant genetic variation of soybean germplasm resources is the basis for overcoming the obstacles in breeding for soybean varieties with high yield and high protein content. Soybean has been cultivated for more than 5000 years and has spread from China to other parts of the world. The rich genetic resources play an important role in promoting the sustainable production of soybean protein worldwide. In this paper, the origin and spread of soybean and the current status of soybean production are reviewed; the genetic characteristics of soybean protein and the distribution of resources are expounded based on phenotypes; the discovery of soybean seed protein-related genes as well as transcriptomic, metabolomic, and proteomic studies in soybean are elaborated; the creation and utilization of high-protein germplasm resources are introduced; and the prospect of high-protein soybean breeding is described.

“…The expression of these genes could be increased in response to the new carbon supply conditions to ensure the correct redistribution of available carbon. In oilseeds, two different transcription factors were reported to regulate the expression of FAD2 genes, such as bHLH in sesame (Kim et al, 2007) and Dof11 in rapeseed (Sun et al, 2018). However, no similar information has been reported in oil fruit.…”

The relative contribution of carbon sources generated from leaves and fruits photosynthesis for triacylglycerol biosynthesis in the olive mesocarp and their interaction with water stress was investigated. With this aim, altered carbon source treatments were combined with different irrigation conditions. A higher decrease in mesocarp oil content was observed in fruits under girdled and defoliated shoot treatment compared to darkened fruit conditions, indicating that both leaf and fruit photosynthesis participate in carbon supply for oil biosynthesis being leaves the main source. The carbon supply and water status affected oil synthesis in the mesocarp, regulating the expression of DGAT and PDAT genes and implicating DGAT1-1, DGAT2, PDAT1-1, and PDAT1-2 as the principal genes responsible for triacylglycerol biosynthesis. A major role was indicated for DGAT2 and PDAT1-2 in well-watered conditions. Moreover, polyunsaturated fatty acid content together with FAD2-1, FAD2-2 and FAD7-1 expression levels were augmented in response to modified carbon supply in the olive mesocarp. Furthermore, water stress caused an increase in DGAT1-1, DGAT1-2, PDAT1-1, and FAD2-5 gene transcript levels.Overall, these data indicate that oil content and fatty acid composition in olive fruit mesocarp are regulated by carbon supply and water status, affecting the transcription of key genes in both metabolic pathways.

“…Manipulation of these regulatory elements has proven to be effective in a number of recent studies. For example, overexpression of transcription factors GmDof4 and GmDof11 was shown to increase the oleic acid content of Brassica napus seeds (Sun et al, 2018). Similarly, oil content of peanut seeds was significantly increased through overexpression of the transcription factor AtLEC1 (Tang et al, 2018).…”

Palm oil is the leading vegetable oil in terms of volume in the world market. Indonesia and Malaysia are the top producers and exporters of the commodity. The global production of palm oil reached 73.5 million tonnes in the period 2018/2019, up from approximately 70.5 million tonnes in 2017/2018. Oil palm is the most productive crop in the world being 10 times more productive than soyabean which produces only about 0.45 t oil per hectare. Nonetheless, the industry is continuously under pressure to improve productivity and sustainability. This will require concerted innovations across the entire palm oil supply chain and fully committed research efforts including upstream technologies to expedite crop improvement. At the Malaysian Palm Oil Board (MPOB), research efforts at development of tools for improving oil palm traits by genetic modification have been augmented more recently with omics-based approaches and all of these innovations are synchronised towards improved product quality. Omics is a multidisciplinary field encompassing genomics, epigenomics, transcriptomics, proteomics and metabolomics. Each of these fields provides an opportunity to understand and view oil palm biology from a global perspective, enabling accelerated discoveries for improved productivity and the development of new and improved varieties. An integrative omics approach promises great value in both phenotyping and diagnostic analyses. With the current technological capabilities, metabolomics is also being exploited for identifying unique chemical fingerprints to detect product contamination and adulteration in oil palm. This effort is actively being conducted in order to position the oil palm industry to meet and optimise the delivery of the highest quality oil with minimum environmental and social concerns. In this review, an overview is given on the current knowledge and progress made in oil palm research, focusing on the application of omics strategies and their integration with high-throughput technologies for oil palm crop improvement, development of geographical traceability system and ensuring that palm oil is free from residual oil contamination.
