What is the origin and composition of cell-free DNA in human embryo spent culture media? Cell-free from media represents a mix maternal embryonic DNA, mixture can be more complex for mosaic embryos. In 2016, ~300 000 embryos were chromosomally and/or genetically analyzed using preimplantation genetic testing aneuploidies (PGT-A) or monogenic disorders (PGT-M) before transfer into uterus. While progress techniques has enabled analysis full karyotype single cell with high sensitivity...
Abstract Most plant pathogens exhibit host specificity but when former barriers to infection break down, new diseases can rapidly emerge. For a number of fungal diseases, there is increasing evidence that hybridization plays major role in driving jumps. However, the relative contributions existing variation versus mutations adapting host(s) unclear. Here we reconstruct evolutionary history two recently emerged populations fungus Pyricularia oryzae are responsible for diseases: wheat blast...
miR-30d is known to be up-regulated during the acquisition of receptivity in endometrium. In order determine transcriptomic and proteomic changes which occur after transient overexpression primary endometrial epithelial cells, vitro cultured human cells (hEECs) were studied experimentally. Two different miRNAs (scramble versus mimic; n = 15) transiently transfected into hEECs from four patients evaluated for mRNA protein expression using Agilent's gene microarray iTRAQ analysis techniques,...
The progressive decline of the ovarian follicle pool leads to reproductive ageing. latter is accompanied by age-related disorders, including various types cancer. In fact, highest rates cancer (OC) occur at postmenopause while OC risk significantly modulated parity records during previous fertile life. We approached age-parity relationship in C57BL/6 mouse model and herein describe presence nonheme iron (hemosiderin) deposits "age pigment" lipofuscin reproductively aged ovaries applying...
Abstract The in vitro derivation of human germ cells has attracted interest the last years, but their direct conversion from somatic not yet been reported. Here we tested ability male to directly convert into a meiotic cell-like phenotype by inducing them with combination selected key cell developmental factors. We started pool 12 candidates that were reduced 6, demonstrating ectopic expression line-related genes PRDM1, PRDM14, LIN28A, DAZL, VASA and SYCP3 induced (hFSK (46, XY) hMSC XY)) ....
Normal 0 21 MicrosoftInternetExplorer4 Species from different fungal genera have been indicated as responsible for the development of trunk diseases grapevines. Greeneria uvicola is bitter rot Vitis vinifera grape bunchesnear harvest, and can also attack other species. In Uruguay, G. was isolated dead arm affected grapevines an endophyte healthy canes. Cadophora luteo-olivacea a phialophora-likeascomycete with wide distribution that asymptomatic wood tissues in Petridisease-affected nursery...
Abstract Breeding programs generate vast amount of data which are often scattered in separate files. This hinders the application modern breeding tools such as multi‐environment analyses and genomic selection. research work describes process consolidating 23 years phenotypic, pedigree, records from Uruguayan national rice ( Oryza sativa L.) program, features structure resulting database. Using a custom‐made R code, we gathered all available 1997 to 2020 corresponding field trials, blast...
Stem rot and aggregated sheath spot are the two major stem diseases affecting rice (Oryza sativa L.) in temperate areas. A third fungal disease, blight, is a disease tropical Resistance to these key objective breeding programs but phenotyping challenged by confounding effects of phenological morphological traits such as flowering time (FT) plant height (PH). This study sought identify quantitative trait loci (QTL) for resistance three after removing FT PH. Two populations advanced germplasm,...
Piscirickettsia salmons, the causative agent of piscirickettsiosis, is genetically divided into two genomic groups, named after reference strains as LF-89-like or EM-90-like. Phenotypic differences have been detected between P. salmonis genogroups, including antibiotic susceptibilities, host specificities and pathogenicity. In this study, we aimed to develop a rapid, sensitive cost-effective assay for differentiation genogroups. Using an in silico analysis 16S rDNA digestion patterns,...
Symptoms corresponding to esca and Petri diseases have been described in Uruguay as being associated with Phaeomoniella chlamydospora Phaeoacremonium spp. Isolates of recovered from diseased grapevines were characterized identified. Additionally, specific primers developed for Pa. evaluated direct detection these fungi asymptomatic grapevine tissues. The bark was removed, the trunk underneath surface-disinfected. Chips symptomatic plated on potato dextrose agar incubated at 25°C. identified...
The rice crop and associated ecosystems constitute a rich mosaic of habitats that preserve biological diversity. Spiders are an abundant successful group natural predators considered efficient in the biocontrol major insect pests agroecosystems. Spider diversity different stages growth from eastern Uruguay was analysed. Field study developed on six farms with rotation system pasture, installed during intercropping stage as cover crop. Six crops distributed three locations were sampled...
Phellinotus, a neotropical genus of wood-decay fungi commonly found on living members the Fabaceae family, was initially described as containing two species, P. neoaridus and piptadeniae. The this genus, along with six other well-established genera some unresolved lineages, are current representatives ‘phellinotus clade’. On hand, based two-loci phylogenetic analysis, entities/lineages clade’ have been in Fomitiporella s.l. In work, we performed four-loci analyses our results shown to be...
Abstract Conservative biological control promotes the use of native natural enemies to limit size and growth pest populations. Although spiders constitute one most important groups predators in several crops, their trophic ecology remains largely unknown, especially for generalist taxa. In laboratory, we assessed predatory behaviour a wandering spider (the wolf Lycosa thorelli (Keyserling, 1877) against arthropods varying positions, all found South American soybean rice crops. As prey used...
Inocutis jamaicensis (Murrill) Gottlieb, J.E. Wright & Moncalvo was identified as the basidiomycetous species associated with ‘hoja de malvon’ grapevine disease in Argentina. Macro and micro-morphological characteristics of fruit bodies corresponded to those described for white-rotting fungus native plant species and Eucalyptus globulus Labill. planted Uruguay. Monokariotic isolates were obtained from basidiospores produced by of I. collected Vitis vinifera L. E. globulus. Dikaryons...

ABSTRACT Adaptive radiations fuel speciation and are characterized by rapid genetic diversification expansion into new ecological niches. Historically, these processes were believed to be driven selection on novel mutations but genomic analyses now indicate that standing variation gene flow often have prominent roles. How “old” is combined, however, its resulting architecture within newly-adapted populations not well understood. We reconstructed a recent radiation in the fungus, Pyricularia...
