Induced Systemic Resistance in the spp.- Jacq.-PepGMV Interaction, Elicited by Defense-Related Gene Expression.

Induced systemic resistance (ISR) is a mechanism involved in the plant defense response against pathogens. Certain members of the genus are able to promote the ISR by maintaining a healthy photosynthetic apparatus, which prepares the plant for future stress situations. The goal of the present study was to analyze the effect of the inoculation of on the expression of genes involved in plant responses to pathogens, as a part of the ISR, during the interaction of infected with PepGMV.

Common weeds as alternate hosts of Mexican variant of Papaya meleira virus in papaya orchards in México.

Presence of alternate hosts of plants is a great threat to the agriculture industry. Plants from several species growing in the papaya orchards affected by papaya sticky disease were examined for Papaya meleira virus (PMeV) infection causing this disease. The viral dsRNA was already detected in some plants from the family Poaceae or in watermelon.

Environmental Surveillance of SARS-CoV-2 RNA in Wastewater and Groundwater in Quintana Roo, Mexico.

The presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA in wastewater has been reported as a result of fecal shedding of infected individuals. In this study, the occurrence of SARS-CoV-2 RNA was explored in primary-treated wastewater from two municipal wastewater treatment plants in Quintana Roo, Mexico, along with groundwater from sinkholes, a household well, and submarine groundwater discharges. Physicochemical variables were obtained in situ, and coliphage densities were determined.

Healthy Photosynthetic Mechanism Suggests ISR Elicited by spp. in Plants Infected with PepGMV.

The aim of this study was to evaluate the effect of inoculation with spp. isolates on the photosynthetic apparatus of plants infected with PepGMV. In vitro and greenhouse experiments were performed to evaluate whether the inoculation improved plants' performance through the increase in photosynthetic efficiency to control PepGMV.

A Lineage of Begomoviruses Encode Rep and AC4 Proteins of Enigmatic Ancestry: Hints on the Evolution of Geminiviruses in the New World.

The begomoviruses (BGVs) are plant pathogens that evolved in the Old World during the Cretaceous and arrived to the New World (NW) in the Cenozoic era. A subgroup of NW BGVs, the " (SLCV) lineage" (S-Lin), includes viruses with unique characteristics. To get clues on the evolutionary origin of this lineage, a search for divergent members was undertaken.
