Plant architecture can act as a pivotal determinant of crop yield by maximizing photosynthate accumulation in grains,but no *** rapeseed ideotype has yet been ***,semi-dwarf and compact(SDC)rapeseed plant types with the capacity to maximize silique number per hectare and seed weight per silique are expected to optimize plant architecture for groundbreaking seed yield,avoiding lodging and promoting mechanical harvest(Liu et al.,2022).In this study,we report the mutant dc1,which exhibits DC plant architecture with significantly increased silique number in the main inflorescence compared with currently cultivated high and loose(HL)plant types like those of elite cultivars(Figure 1A and Supplemental Figure 1).

The study explored the influence of defatted flaxseed gum powder(DFGP) on the stability and quality of sesame paste by measuring and analyzing its composition, color, texture, particle size, centrifugal oil separation rate,rheological properties, and microstructure. The results showed that the moisture and polysaccharide content of sesame paste was increased as the DFGP increased. Additionally, the hardness, gumminess, and chewiness of the sesame paste was improved, while the presence of particles with small particle size(1–100 μm) was *** rate of oil precipitation was reduced by 28.99% when the amount of DFGP was 6%. The sesame paste samples exhibited pseudoplastic behavior, demonstrating shear thinning. As the shear rate increased, the apparent viscosity of sesame paste gradually decreased. Both the storage modulus(G’) and the loss modulus(G’’) increased as the shear frequency increased. The microstructure observation revealed that protein and oil were evenly distributed in the sesame paste system, and the addition of DFGP enhanced the bonding between oil and *** study can provide valuable references for high-quality sesame paste products in the food industry.
