Phytocyanins (PCs), plant-specific blue copper proteins, are crucial for various biological processes during plant development. However, a comprehensive characterization of the soybean PC gene family (GmPC) is lacking. In this study, we performed genome-wide screening of soybean PC genes, and 90 PC genes were identified in the soybean genome. Further analysis revealed that the GmPC family was categorized into four subfamilies (stellacyanins, GmSCs; uclacyanins, GmUCs; plantacyanins, GmPLCs; and early nodulin-like proteins, GmENODLs). In-depth analysis revealed that each specific GmPC subfamily exhibited similar characteristics, with segmental duplications playing a major role in expanding the members of GmPC. Additionally, synteny and evolutionary constraint analyses suggested that GmPCs have undergone strong selective pressure for purification during the evolution of soybeans. The promoter cis-regulatory elements analysis of GmPCs suggested that GmPCs might play a crucial role in various stress responses. The expression patterns of GmPCs exhibited tissue-specific variations. Moreover, 23 of the GmPCs may be involved in soybean's response to salt stress. In all, our study presents a systematic overview of GmPC, which not only provides a valuable foundation for further functional investigations of GmPCs, but also offers new insights into the mechanism of soybean salt tolerance.

Molecularly imprinted polymers (MIPs) are obtained by initiating the polymerization of functional monomers surrounding a template molecule in the presence of crosslinkers and porogens. The best adsorption performance can be achieved by optimizing the polymerization conditions, but this process is time consuming and labor-intensive. Theoretical calculation based on calculation simulations and intermolecular forces is an effective method to solve this problem because it is convenient, versatile, environmentally friendly, and inexpensive. In this article, computational simulation modeling methods are introduced, and the theoretical optimization methods of various molecular simulation calculation software for preparing molecularly imprinted polymers are proposed. The progress in research on and application of molecularly imprinted polymers prepared by computational simulations and computational software in the past two decades are reviewed. Computer molecular simulation methods, including molecular mechanics, molecular dynamics and quantum mechanics, are universally applicable for the MIP-based materials. Furthermore, the new role of computational simulation in the future development of molecular imprinting technology is explored. [ABSTRACT FROM AUTHOR]
