Since the late 1980s, tomato production in Costa Rica has been affected by diseases caused whitefly-transmitted begomoviruses. The first was yellow mottle virus (ToYMoV), a locally evolved New World (NW) bipartite begomovirus associated with disease (ToYMoD). In 1990s, invasive NW leaf curl Sinaloa (ToLCSiV) detected and become established ToYMoD. Finally, Old (OW) monopartite (TYLCV) 2012 also is causing (TYLCD). present study, we investigated invasion biology of these tomato-infecting...

Tomato chlorosis virus (ToCV) is an emerging whitefly-transmitted crinivirus (2). In Costa Rica in 2007, ToCV was detected field-grown and greenhouse tomato (Solanum lycopersicum L.) plants causing symptoms of severe yellowing foliar (1). To identify alternative hosts that may serve as reservoirs, 78 samples were collected from multiple species common weeds growing adjacent to nurseries the Cartago Province, where previously identified, during autumn 2008 summer 2009. The on basis presence...

In September 2008, a survey of whiteflies and whitefly-borne viruses was performed in 11 pepper-growing greenhouses the province Cartago, Costa Rica. During this survey, vast majority sweet pepper (Capsicum annuum cv. Nataly) plants showed interveinal chlorosis, enations, necrosis, mild upward leaf curling. Large populations were present they found to be composed only Trialeurodes vaporariorum. Total RNA from frozen plant samples extracted with TRI Reagent (Molecular Research Inc.,...

Abstract Begomoviruses (genus Begomovirus , family Geminiviridae ) have emerged as important plant pathogens in tropical and subtropical regions worldwide. Although these viruses were reported during the 1970s Costa Rica, they are still poorly known. Therefore, objective of this study was to analyse diversity distribution begomoviruses commercial tomato sweet pepper fields from different agricultural production systems major growing Rica. A total 651 plants randomly sampled greenhouses open...

One of the most important invasive and harmful members genus Begomovirus (family Geminiviridae) is monopartite Tomato yellow leaf curl virus (TYLCV), which widespread over world associated with tomato disease (TYLCD). (Solanum lycopersicum) plants infected TYLCV show upward curling yellowing. In Latin America, isolates have been reported from Cuba, Dominican Republic, Mexico Puerto Rico (1), Guatemala (GenBank Accession No. GU355941), Venezuela (partial genome sequence DQ302033). Costa Rica,...

We estimated the genetic diversity of 50 Jatropha curcas samples from Costa Rican germplasm bank using 18 EST-SSR, one G-SSR and nrDNA-ITS markers. also evaluated phylogenetic relationships among nuclear ribosomal ITS Non-toxicity was G-SSRs SCARs A Neighbor-Joining (NJ) tree a Maximum Likelihood (ML) were constructed SSR markers sequences, respectively. Heterozygosity moderate (He = 0.346), but considerable compared to worldwide values for J. curcas. The PIC (PIC 0.274) inbreeding...

Agro-industrial waste from tropical environments could be an important source of lactic acid bacteria (LAB) with probiotic potential.Twelve LAB isolates were isolated pineapple silages. The species identification was carried out considering 16S rRNA and pheS genes. Experiments to evaluate the potential included survival under simulated gastrointestinal environment, in vitro antagonistic activity (against Salmonella spp. Listeria monocytogenes), auto-aggregation assays, antibiotic...

Web blight is one of the main diseases that affects bean (Phaseolus vulgaris) cultivation. It infects diverse organs at any growth stage plant and can be present different altitudes in a humid tropical climate. The causal agent this disease Thanatephorus cucumeris its sexual Rhizoctonia solani anamorph. objective investigation was to characterize molecular isolates R. obtained from plants production regions Costa Rica determine their virulence. Fifty-one samples symptomatic were collected...

The tobacco whitefly Bemisia tabaci (Gennadius) cryptic species complex and of the greenhouse Trialeurodes vaporariorum (Westwood) are extensively reported as destructive pests in vegetable crops worldwide. A survey was conducted 2011 2012 to determine occurrence genetic diversity present populations these whiteflies major production areas Costa Rica. Insect samples were collected from sweet pepper ( Capsicum annuum L.), tomato Solanum lycopersicum common bean Phaseolus vulgaris L.) weeds...

Desde inicios del decenio de 1990 y manera casi simultanea, se empezaron a observar afecciones desconocidas en numerosos cultivos, sobre todo regiones tropicales subtropicales. Dichas enfermedades eran causadas por begomovirus hasta entonces poco estudiados. Su vector es la mosca blanca Bemisia tabaci (Hemiptera: Aleyrodidae), que no habian registrado poblaciones tan desmedidas areas agricolas. Ello origino una seria crisis produccion nivel mundial, con perdidas millonarias para los...

Introduction: King grass (Cenchrus purpureus (Schumach.) Morrone, syn. Pennisetum purpuphoides) and pineapple peel (Ananas comosus) silages are food alternatives for livestock in conditions of feed shortage. Objective: To describe the dynamics microbiota present king silage during fermentation process using next generation sequencing (NGS) to evaluate protective effect Lacticaseibacillus paracasei_6714 as a inoculum against Listeria monocytogenes. Methods: We used an unrestricted randomized...

In Costa Rica, tomato (Solanum lycopersicum Linnaeus) Linnaeus (Solanales: Solanaceae) is one of the crops most severely affected by whiteflies (Hemiptera: Aleyrodidae) Trialeurodes vaporariorum (Westwood) and Bemisia tabaci (Gennadius) species complex. The objective this study was to monitor spatial distribution diversity these detect presence secondary bacterial endosymbionts in individuals collected areas intensive production. total, 628 whitefly were identified level using restriction...

Lactic acid bacteria (LAB) with potential for the development of multi-product processes are necessary valorization side streams obtained during biotechnological production lactic (LA). In this study, 14 LAB strains isolated from pineapple agro-industrial residues in Costa Rica were cultivated microplates, and six highest growth selected fermentation microbioreactors to evaluate LA acetic acid, consumption glucose. Lacticaseibacillus paracasei 6710 L. 6714 presented OD600 values (1.600...

The production of lactic acid (LA) through the microbial conversion agro-industrial residuals is an important process in biotechnology industry. growth kinetics 30 strains bacteria (LAB) isolated from residues were determined and nine selected for microbioreactor fermentation. Lactiplantibacillus pentosus_70-1 (1.662) L. pentosus_19-2 (1.563) showed highest OD600 values, whereas rates observed (0.267 h−1) Weissella soli_31 (0.256 h−1).
