Unification of Electromagnetic Interactions and Gravitational Interactions [PDF]

Commun.Theor.Phys.38:322-326,2002, 2002
Unified theory of gravitational interactions and electromagnetic interactions is discussed in this paper. Based on gauge principle, electromagnetic interactions and gravitational interactions are formulated in the same manner and are unified in a semi-direct product group of U(1) Abel gauge group and gravitational gauge group.

Insect eggs trigger systemic acquired resistance against a fungal and an oomycete pathogen. [PDF]

, 2021
Plants are able to detect insect eggs deposited on leaves. In Arabidopsis, eggs of the butterfly species Pieris brassicae (common name large white) induce plant defenses and activate the salicylic acid (SA) pathway.

The Hippo kinase LATS2 impairs pancreatic β-cell survival in diabetes through the mTORC1-autophagy axis

Nature Communications, 2021
Diabetes is characterized by dysfunction and loss of beta-cells, and promoting beta-cell survival is of therapeutic interest. Here the authors show that Large-tumor suppressor 2 (LATS2), a core component of the Hippo signaling pathway, induces beta-cell ...

Strain-level characterization of broad host range mobile genetic elements transferring antibiotic resistance from the human microbiome

Nature Communications, 2022
Here, Forster et al. compare 1354 cultured commensal strains (540 species) to 45,403 pathogen strains (12 species), identifying 64,188 MGE-mediated antibiotic resistance gene transfer events between the two groups, and show that 15 broad host range MGEs ...

A symbiotic footprint in the plant root microbiome

Environmental Microbiome, 2023
Background A major aim in plant microbiome research is determining the drivers of plant-associated microbial communities. While soil characteristics and host plant identity present key drivers of root microbiome composition, it is still unresolved ...

ECS1 and ECS2 suppress polyspermy and the formation of haploid plants by promoting double fertilization

eLife, 2023
The current pace of crop plant optimization is insufficient to meet future demands and there is an urgent need for novel breeding strategies. It was previously shown that plants tolerate the generation of triparental polyspermy-derived plants and that ...

Host adaptation in gut Firmicutes is associated with sporulation loss and altered transmission cycle

Genome Biology, 2021
Background Human-to-human transmission of symbiotic, anaerobic bacteria is a fundamental evolutionary adaptation essential for membership of the human gut microbiota.

Elucidation of Essential Genes and Mutant Fitness during Adaptation toward Nitrogen Fixation Conditions in the Endophyte Azoarcus olearius BH72 Revealed by Tn-Seq

Microbiology Spectrum, 2022
Azoarcus olearius BH72 is a diazotrophic model endophyte that contributes fixed nitrogen to its host plant, Kallar grass, and expresses nitrogenase genes endophytically.

Two-dimensional three-body quadrupole-quadrupole interactions [PDF]

, 2021
Similar to interactions between dipoles, or van der Waals interactions, quadrupole-quadrupole interactions are interactions between quadrupoles. In this article, we study the quadrupole interactions between highly excited atoms or Rydberg atoms. In addition, unlike many other calculations, in which the primary focus was on the one-dimensional two-body ...

Critical structural elements for the antigenicity of wheat allergen LTP1 (Tri a 14) revealed by site-directed mutagenesis

Scientific Reports, 2022
Lipid transfer proteins (LTPs) were identified as allergens in a large variety of pollens and foods, including cereals. LTPs belong to the prolamin superfamily and display an α-helical fold, with a bundle of four α-helices held together by four disulfide
