Alphaviruses enter host cells via receptor-mediated endocytosis, using various cellular surface receptors such as matrix remodeling-associated protein 8 (MXRA8), low-density lipoprotein receptor class A domain-containing 3 (LDLRAD3), and very low-density lipoprotein receptor (VLDLR), which facilitate binding to the viral glycoproteins. Following entry, viral proteins are expressed and nonstructural proteins assemble into replication complexes in host cells, driving RNA synthesis and genome replication. Viral assembly occurs at the plasma membrane, where nascent virions bud from the host cell in a process driven by capsid and spike proteins.

Among these systems, the clustered regularly interspaced short palindromic repeats (CRISPR) and their CRISPR-associated proteins (Cas) are notably prevalent in LAB. The early characterization of this adaptive immune system was closely tied to the cheese industry, particularly with <i>Streptococcus thermophilus</i> in which CRISPR-Cas systems are ubiquitous and highly active. This review underscores the contributions of <i>S. thermophilus</i> and its virulent phages to our understanding of the function and mechanisms of CRISPR-Cas systems.

Each organelle has distinct structure-function relationships that change in response to diverse stimuli. Such remodeling events further affect organelle-organelle interaction networks facilitated by membrane contact sites, thereby activating rapid intra- and intercellular communication cascades. As viruses rely on repurposing the host cell machinery during infections, organelle remodeling is a fundamental facet and outcome of all viral infections. Some organelle remodeling events are unique to particular viruses, while others are shared by an array of viruses. Here, we review knowledge derived from this expanding yet still underexplored research area of infection-induced organelle remodeling. We focus on the molecular mechanisms used by viruses to temporally control organelle structure-function relationships.

This review examines the development of these ideas over the last 75 years from an ecological perspective using a mixture of theoretical and empirical studies.

I then consider how models of Fenner's study gradually developed into a major area of theoretical epidemiology. The emerging concepts were constantly challenged by new empirical studies that illustrated how virulence may be modified by culling, vaccination, and different forms of heterogeneity within and between species and spatial heterogeneity. The emerging field of phylodynamics has provided multiple new tools to analyze and visualize the evolution of virulence and a much broader perspective on the diversity of viruses and their hosts.

The dynamics of the transcription and replication are tightly regulated throughout the viral life cycle, with a switch from transcription to replication in the later stages of infection being essential for efficient progeny virus production. The mechanism by which the virus achieves the switch has emerged recently through structural and functional studies.

PLRV threatens global potato cultivation, especially in regions where vector management options are limited. In this review, we describe the effect of PLRV on the aphid holobiont and highlight studies of the evolutionary and mechanistic ways in which PLRV influences the aphid holobiont during plant infection. We explore ideas to address the pressing need for aphid and PLRV management strategies by targeting interactions within the holobiont.
