Expression of Arabidopsis WRI1 and DGAT1 during soybean embryo development alters oil and carbohydrate composition

ABSTRACT: Soybean (Glycine max [L.] Merr.) is the largest feedstock for protein and second largest source of vegetable oil in the world. In order to evaluate whether the expression of ATWRI1 and AtDGAT1 could direct carbon flow towards lipid accumulation, we generated three independent transformation events (WD-1, -2, and -3). The transgenic events were evaluated in three field trials (2018, 2019, and 2020) as well as greenhouse conditions. RNAseq analysis was performed in immature embryos of both transgenic events grown under greenhouse conditions. We discovered that Glycolysis and FA metabolism enzymes are enriched in WD differentially expressed genes during seed development.

Project description:<h4>Background</h4>Bioconversion of wood into bioproducts and biofuels is hindered by the recalcitrance of woody raw material to bioprocesses such as enzymatic saccharification. Targeted modification of the chemical composition of the feedstock can improve saccharification but this gain is often abrogated by concomitant reduction in tree growth.<h4>Results</h4>In this study, we report on transgenic hybrid aspen (Populus tremula × tremuloides) lines that showed potential to increase biomass production both in the greenhouse and after 5 years of growth in the field. The transgenic lines carried an overexpression construct for Populus tremula × tremuloides vesicle-associated membrane protein (VAMP)-associated protein PttVAP27-17 that was selected from a gene-mining program for novel regulators of wood formation. Analytical-scale enzymatic saccharification without any pretreatment revealed for all greenhouse-grown transgenic lines, compared to the wild type, a 20-44% increase in the glucose yield per dry weight after enzymatic saccharification, even though it was statistically significant only for one line. The glucose yield after enzymatic saccharification with a prior hydrothermal pretreatment step with sulfuric acid was not increased in the greenhouse-grown transgenic trees on a dry-weight basis, but increased by 26-50% when calculated on a whole biomass basis in comparison to the wild-type control. Tendencies to increased glucose yields by up to 24% were present on a whole tree biomass basis after acidic pretreatment and enzymatic saccharification also in the transgenic trees grown for 5 years on the field when compared to the wild-type control.<h4>Conclusions</h4>The results demonstrate the usefulness of gene-mining programs to identify novel genes with the potential to improve biofuel production in tree biotechnology programs. Furthermore, multi-omic analyses, including transcriptomic, proteomic and metabolomic analyses, performed here provide a toolbox for future studies on the function of VAP27 proteins in plants.

Project description:Atherosclerosis is the preliminary cause of coronary artery disease, one of the diseases that ac-count for the largest number of fatal mortalities. Physical activity is an effective strategy to restrain atherosclerosis from deterioration. Evidence indicated that the changes of proteomic profile is highly associated with the atherosclerosis development, but the mechanism behind the exercise for atherosclerosis amelioration has not yet been investigated from the proteomics perspective. Hence, the proteomic profiles could further elucidate the systematic effects of exercise interven-tion on ApoE knockout atherosclerotic model and high fat diet intervention. In current study, Apoeem1Narl/Narl mice were randomly allocated into a normal diet (ND), western diet (WD) and WD with 12 weeks exercise intervention (WD EX) groups. The plasm proteome between WD and WD EX demonstrate the significant difference, and ten major pathways, including cardiovascular disease (CVD)–hematological disease, cellular compromise–inflammatory response, protein synthesis, connective tissue disorders, cellular movement–immune cell tracking, inflammatory response, etc., were generated by the IPA analysis. The fourteen proteins (PROS, PROZ, C2, F5, C5, SERPINA 10, FGB, FGG, CFB, F12, CRP, CFHR1, HABP2, and PPIA) critically involved in CVD–hematological disease pathway showed significant difference among groups. The PROS, F5, C5, FGG, and CFB levels associated with thrombosis and atherosclerosis induced by WD were significantly decreased by exercise intervention in WD EX. Furthermore, the F5 and FGG were well-demonstrated the important roles for thrombosis of atherosclerotic pathogenesis but the complement factor C5 in the development of atherosclerosis is not fully understood. In current study, the exercise could significantly alleviate the significantly elevated C5 and inflammation induced by WD group in accordance to amelioration of atherosclerosis. Therefore, exercise could mitigate chemotaxis through the modulation of the C5 level and innate immunity, thereby alle-viating the pathogenesis of atherosclerosis in western-diet induced obese mice.
