The road of lipid migration in flaxseed (Linum usitatissimum L.) during germination.

Lipids are essential sources of carbon and energy during flaxseed germination; however, the dynamic changes in key lipid metabolites, pathways, and their locations remain unclear. This study revealed that oil bodies migrated from well-distributed locations to the cell wall between 0-2 d, with cell contours gradually blurring during 2-3 d, initiating the germination process. Subsequently, the order of oil body migration was leaf > stem > root during 4-7 d.

Background: We aim to comprehensively analyze and validate the prognostic efficacy of tetraspanin 4 (TSPAN4) and several other migrasome-related markers in hepatocellular carcinoma (HCC).
Methods: The expression, diagnostic, and prognostic efficacy of five migrasome-related genes in HCC were analyzed using several databases. Five pairs of adjacent non-tumor tissues and HCC tissues were used to validate the expression.

Seed shattering (SS) functions are a survival mechanism in plants, enabling them to withstand adverse environmental conditions and ensure reproduction. However, this trait limits seed yield. , a perennial forage grass with many favorable traits, is constrained by SS, limiting its broader application.

We demonstrate that a short oligonucleotide complementary to a G-quadruplex domain can invade this iconic, noncanonical DNA secondary structure in ways that profoundly influence the properties and differential occupancies of the resulting DNA polymorphic products. Our spectroscopic mapping of the conformational space of the associated reactants and products, both before and after strand invasion, yield unanticipated outcomes which reveal several overarching features. First, strand invasion induces the disruption of DNA secondary structural elements in both the invading strand (which can assume an iDNA tetrad structure) and the invaded species (a G-quadruplex).

Norway maple and sycamore belong to the Acer genus and produce desiccation-tolerant and desiccation-sensitive seeds, respectively. We investigated the seed germination process at the imbibed and germinated stages using metabolomic and proteomic approaches to determine why sycamore seeds germinate earlier and are more successful at establishing seedlings than Norway maple seeds under controlled conditions. Embryonic axes and embryonic axes with protruded radicles were analyzed at the imbibed and germinated stages, respectively.
