Competing Hexagonal and Square Lattices on a Spherical Surface.

The structural properties of packed soft-core particles provide a platform to understand the cross-pollinated physical concepts in solid-state and soft-matter physics. Confined on a spherical surface, the traditional differential geometry also dictates the overall defect properties in otherwise regular crystal lattices. Using molecular dynamics simulation of the Hertzian model as a tool, we report here the emergence of new types of disclination patterns: domain and counter-domain defects, when hexagonal and square patterns coexist.

SPM43.1 contributes to acid-resistance of non-symplasmata-forming cells in Pantoea agglomerans YS19.

Pantoea agglomerans YS19 is a rice endophytic bacterium characterized to form multicellular biofilm-like structures called symplasmata. Phenotypic distinctions between symplasmata-forming cells and planktonic cells are crucial for understanding YS19's survival strategies. In this study, a 43.

Rice endophyte Pantoea agglomerans YS19 forms multicellular symplasmata via cell aggregation.

Pantoea agglomerans is characterized by the formation of multicellular symplasmata. One unanswered question regarding this bacterium is how these structures are formed. In this study, the rice diazotrophic endophyte P.
