This theoretical article begins by introducing and discussing the historical background, core concept "Fourth Love" and its related categories.

() induces petal senescence through a novel JA-associated regulatory pathway in .

Unlabelled: Flowers are crucial for the reproduction of flowering plants and their senescence has drastic effects on plant-animal interactions as well as pollination. Petal senescence is the final phase of flower development which is regulated by hormones and genes. Among these, jasmonic acid (JA) has emerged as a major contributor to petal senescence, but its molecular mechanisms remain elusive.

DNA Nanostructures: Self-Adjuvant Carriers for Highly Efficient Subunit Vaccines.

Subunit vaccines based on antigen proteins or epitopes of pathogens or tumors show advantages in immunological precision and high safety, but are often limited by their low immunogenicity. Adjuvants can boost immune responses by stimulating immune cells or promoting antigen uptake by antigen presenting cells (APCs), yet existing clinical adjuvants struggle in simultaneously achieving these dual functions. Additionally, the spatial organization of antigens might be crucial to their immunogenicity.
