“…This result can be considered successful since the conversion of the molarity was based on an estimated value of molar mass. Indeed, the vegetable oil composition may considerably vary due to abiotic factors, such as temperature, soil salinity, sun exposition, and water supply [ 41 ]. Considering the complex composition of EOs and the very limited number of studies employing NMR for the quality control of these valuable products, this tool which improves and finalizes the previous work based on recognition of the adulterant oil, can be considered in our opinion both pioneering and promising.…”

Essential oils (EOs) are more and more frequently adulterated due to their wide usage and large profit, for this reason accurate and precise authentication techniques are essential. This work aims at the application of qNMR as a versatile tool for the quantification of vegetable oils potentially usable as adulterants or diluents in EOs. This approach is based on the quantification of both 1H and 13C glycerol backbone signals, which are actually present in each vegetable oil containing triglycerides. For the validation, binary mixtures of rosemary EO and corn oil (0.8–50%) were prepared. To verify the general feasibility of this technique, other different mixtures including lavender, citronella, orange and peanut, almond, sunflower, and soy seed oils were analyzed. The results showed that the efficacy of this approach does not depend on the specific combination of EO and vegetable oil, ensuring its versatility. The method was able to determine the adulterant, with a mean accuracy of 91.81 and 89.77% for calculations made on 1H and 13C spectra, respectively. The high precision and accuracy here observed, make 1H-qNMR competitive with other well-established techniques. Considering the current importance of quality control of EOs to avoid fraudulent practices, this work can be considered pioneering and promising.

“…Following harvest, pennycress seed can be pressed for oil and usually contains between 260 and 360 g kg −1 of oil (Cubins et al., 2019). When compared with other common oilseed species grown in the region (e.g., soybean [ Glycine max [L.] Merr] and canola [ Brassica napus L.]), pennycress seed produces a comparable or greater amount of oil per seed (Balbino, 2017). In the context of the agricultural landscape in the Upper Midwest, pennycress may provide additional oil yield alongside a soybean double crop, providing growers with an additional source of revenue in a given growing season.…”

Harvest aids did not advance maturity of non‐shatter pennycress

et al. 2023

Reliance on summer annual crops in the Upper Midwest results in fallow land from late fall through early spring, providing opportunities to integrate winter crops, such as pennycress (Thlapsi arvense L.), onto the landscape. Pennycress agronomics have primarily been studied using unimproved wild-type lines prone to seed shatter, resulting in significant yield loss if not harvested early. However, high plant and seed moisture complicates harvest and seed storage. A new breeding line with a reducedshatter mutation made it possible to use harvest aids to reduce plant moisture without the risk of seed loss. The objectives of this study were to quantify the reduction in pennycress seed and biomass moisture after applying a harvest aid and to assess the seed yield, oil content, and crude protein of the reduced-shatter line. This study was conducted over the 2018-2019 and 2019-2020 growing seasons with '"IO217" pennycress in Rosemount, MN. Seed moisture decreased to a similar level by harvest maturity regardless of treatment while swathing was the most effective method of reducing biomass moisture. Natural senescence decreased pennycress moisture content to a harvestable level at the same rate as treated plants, indicating that a harvest aid is not required at this time. Seed yield was two to six times higher than in studies using unimproved pennycress lines. Challenges associated with wild-type pennycress lines, such as uneven germination and late maturation, were prevalent in this study and further genetic improvement will be necessary to ensure successful pennycress production in the Upper Midwest.

“…Global plant oil production increased from approximately 161.6 million metric tons in 2012 to 213.2 million in 2022 ( Statista, 2022 ). However, due to the decreases in agricultural land and the rapid climate changes, it has become challenging to meet the growing demands for edible plant oil ( Huang et al, 2016 ; Balbino, 2017 ; Yang et al, 2018 ; Chen et al, 2020 ). To address this need, it is essential to utilize plant species with high oil production and solid environmental adaptation ( Bailey-Serres et al, 2019 ; Ortiz et al, 2020 ).…”

Yellowhorn (Xanthoceras sorbifolium) is an oil-bearing tree species growing naturally in poor soil. The kernel of yellowhorn contains valuable fatty acids like nervonic acid. However, the genetic basis underlying the biosynthesis of valued fatty acids and adaptation to harsh environments is mainly unexplored in yellowhorn. Here, we presented a haplotype-resolved chromosome-scale genome assembly of yellowhorn with the size of 490.44 Mb containing scaffold N50 of 34.27 Mb. Comparative genomics, in combination with transcriptome profiling analyses, showed that expansion of gene families like long-chain acyl-CoA synthetase and ankyrins contribute to yellowhorn fatty acid biosynthesis and defense against abiotic stresses, respectively. By integrating genomic and transcriptomic data of yellowhorn, we found that the transcription of 3-ketoacyl-CoA synthase gene XS04G00959 was consistent with the accumulation of nervonic and erucic acid biosynthesis, suggesting its critical regulatory roles in their biosynthesis. Collectively, these results enhance our understanding of the genetic basis underlying the biosynthesis of valuable fatty acids and adaptation to harsh environments in yellowhorn and provide foundations for its genetic improvement.
