1. Identification of Potential Inhibitors of Severe Acute Respiratory Syndrome-Related Coronavirus 2 (SARS-CoV-2) Main Protease from Non-Natural and Natural Sources: A Molecular Docking Study
So far, there is neither a vaccine nor a specific antiviral drug to prevent or treat COVID-19 (coronavirus disease) infection. Recent studies have been done to investigate the capacity of human immunodeficiency virus type 1 (HIV-1) protease inhibitors be used in the treatment of COVID-19 patients. Some of those drugs have shown to be promising. Natural chemi

2. Chemical diversity and activity profiles of HIV-1 reverse transcriptase inhibitors from plants
Abstract Current challenges to antiretroviral therapy have opened new vistas in the search for novel drugs from natural products. This review focusses on plants as sources of inhibitors for human immunodeficiency virus type 1 (HIV-1) reverse transcriptase. Based on a systematic search of the literature, anti-HIV-1 reverse transcriptase activity was recorded

3. Etiology, occurrence and epidemiology of a begomovirus disease in passionflower in the southwest of Bahia
ABSTRACT: Severe mosaic symptoms, accompanied by yellow spots, abnormally small leaves, fruit malformation and cracking, reduced plant growth, and high levels of whitefly (Bemisia tabaci MEAM1) infestation were observed in passionflower (Passiflora edulis) orchards in southwestern Bahia, Brazil. The aim of this work was to identify the species of begomovirus

4. Probing the Pharmacological Parameters, Molecular Docking and Quantum Computations of Plant Derived Compounds Exhibiting Strong Inhibitory Potential Against NS5 from Zika Virus
ABSTRACT Zika virus (ZIKV) is known for microcephaly and neurological disease in humans and the nonstructural proteins of ZIKV play a fundamental role in the viral replication. Among the seven nonstructural proteins, NS5 is the most conserved and largest protein. Two major functional domains of NS5 i.e. methyltransferase (MTase) and RNA-dependent RNA polymer

5. Alternative hosts of Cowpea aphid-borne mosaic virus (CABMV) in sesame (Sesamum indicum) crops grown in Paraguay
Sesame (Sesamum indicum L.) production in Paraguay has been severely affected by infection with Cowpea aphid-borne mosaic virus (CABMV), which causes a disease known locally as ka'are. Because very little is known about the epidemiology of this disease, a survey was performed in fields surrounding affected sesame plantations to identify CABMV-infected plants

6. Present status of citrus leprosis in Argentina and Paraguay
Citrus leprosis (CL) was first described in South America in the 1920's. It is considered similar to a disease first observed back to 1860 in Florida. It is a destructive disease characterized by localized lesions on the leaves, fruits and stems, which may lead to the death of the affected plant if left untreated. Around 1940, CL was demonstrated to be trans

7. Aphelenchoides besseyi Christie (Nematoda: Aphelenchoididae), agente causal del amachamiento del frijol común
Identification of the causal agent of the disease "amachamiento" of common bean was carried out using four tests: analysis of double strand RNA (dsRNA) of viral origin, DAS-ELISA technique, applying Koch's postulates and the pathogenicity test. The analysis to detect dsRNA brought about two bands of approximately 1100 and 3200 bp, a similar pattern of bands

8. Biological, serological and molecular characterization of Brazilian isolates of Zucchini yellow mosaic virus / Caracterização biológica, sorológica e molecular de isolados brasileiros do vírus do mosaico amarelo da abobrinha
O vírus do mosaico amarelo da abobrinha (Zucchini yellow mosaic virus - ZYMV) é provavelmente um dos mais dinâmicos e prejudiciais vírus emergentes de plantas. Desde sua primeira detecção na Itália e na França em 1973 e 1979, respectivamente, o ZYMV tem sido reportado em mais de 50 países variando de condições climáticas tropicais a temperadas em

9. Tomato severe rugose virus (ToSRV) e Tomato chlorosis virus (ToCV): relações com a Bemisia tabaci biótipo B e eficiência de um inseticida no controle da transmissão do ToSRV / Tomato severe rugose virus (ToSRV) and Tomato chlorosis virus (ToCV): relashionship with Bemisia tabaci biotype B and efficiency of an insecticide to control the transmission of ToSRV
A cultura do tomateiro (Solanum lycopersicum L.) é importante mundialmente devido ao alto consumo de seus frutos. Nos últimos anos surgiram nesta cultura no Brasil alguns vírus emergentes com altas taxas de disseminação, como begomovírus e crinivírus, transmitidos pela Bemisia tabaci biótipo B, que podem causar danos à produção do tomateiro. A esp

10. Desempenho horticultural de clones de lima ácida `Tahiti´ enxertados em citrumelo `Swingle´ cultivados com e sem irrigação / Horticultural performance of Tahiti lime selections grafted on Swingle citrumelo under irrigated and non-irrigated conditions
A partir da década de 1990, em função da valorização da fruta no mercado interno e do aumento das exportações da fruta in natura, observou-se aumento da importância da lima ácida Tahiti (Citrus latifolia (Yu. Tanaka) Tanaka) sob os aspectos econômico e social no agronegócio brasileiro. A diversidade genética da espécie é pequena e os cultivos c

11. Resposta de genótipos de citros à leprose e variabilidade genética da ORF p29 do vírus da leprose dos citros C (CiLV-C) / Response of citrus genotypes to leprosis and genetic variability of ORF p29 from Citrus leprosis virus C (CiLV-C)
Viruses have, potentially, broad genetic variability because of their need to adapt to several changes that they are exposed to. Therefore, genetic variability is essential for their survival; it is the first step to adapt to a new host, to break resistance down, to change symptoms and virulence, which justifies the interest in studies in this area. These st

12. Caracterização biológica e molecular de isolados do vírus do mosaico da cana-de-açúcar do Estado de São Paulo / Biological and molecular characterization of isolates of Sugarcane mosaic virus from São Paulo state
A cana-de-açúcar é cultivada em diversos países do mundo. O Brasil é atualmente o maior produtor mundial de cana-de-açúcar e o maior exportador dos produtos derivados dessa espécie, tais como açúcar e etanol. A cultura da cana-deaçúcar apresenta muitos problemas fitossanitários que prejudicam a produção, entre eles o causado pelo vírus do mos
