Occurrence of Yam Mosaic Virus and Yam Mild Mosaic Virus on spp. Germplasm Collection in Cuba-Epidemiology of Associated Diseases.

Potyvirus diseases are one of the main challenges facing the production of yam ( spp.). The objective of this study was to identify the potyviruses present in the spp.

Uncovering the Mechanisms: The Role of Biotrophic Fungi in Activating or Suppressing Plant Defense Responses.

This paper discusses the mechanisms by which fungi manipulate plant physiology and suppress plant defense responses by producing effectors that can target various host proteins. Effector-triggered immunity and effector-triggered susceptibility are pivotal elements in the complex molecular dialogue underlying plant-pathogen interactions. Pathogen-produced effector molecules possess the ability to mimic pathogen-associated molecular patterns or hinder the binding of pattern recognition receptors.

Phylodynamics of sunflower chlorotic mottle virus, an emerging pathosystem.

Distribution and epidemiological patterns of sunflower chlorotic mottle virus (SCMoV) in sunflower (Helianthus annuus L.) growing areas in Argentina were studied from 2006 to 2017. The virus was detected exclusively in the Pampas region (Entre Ríos, Santa Fe, Córdoba, La Pampa and Buenos Aires provinces).
