Drought induces distinct growth response, protection, and recovery mechanisms in the maize leaf growth zone
(2015-10)Drought is the most important crop yield-limiting factor, and detailed knowledge of its impact on plant growth regulation is crucial. The maize (Zea mays) leaf growth zone offers unique possibilities for studying the ... -
Variabilidad de la duración promedio de la gestación intra-piara y su relación con el orden de parto en cerda = Intra-herd variability of the average duration of pregnancy and its relationship with birth order in sows
(2015-12)La duración media de la gestación en las cerdas varía entre 113 a 117 días, siendo influida por varios factores, incluido el estadío reproductivo materno. La importancia de conocer la duración media en cada granja radica ... -
Use of silencing reporter and agroinfiltration transient assays to evaluate the potential of hpRNA construct to induce multiple tospovirus resistance
(2015-12)Tospoviruses are devastating plant viruses causing severe economic losses in a diverse range of crops worldwide. Here, we describe the development and evaluation of an RNA interference (RNAi) broad-spectrum virus resistance ... -
Essential oils and their combinations with iprodione fungicide as potential antifungal agents against withe rot (Sclerotium cepivorum Berk) in garlic (Allium sativum L.) crops
(2016)This study was conducted to evaluate essential oils (EOs) and their binary combinations with fungicideiprodione (Ip) as a potential fungicide against Sclerotium cepivorum Berk in order to reduce the amountof pesticide ... -
Cultivo in vitro de anteras como estrategia para el mejoramiento genético de Buffelgrass (Cenchrus ciliaris L)
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2016)Buffelgrass es una gramínea forrajera que se reproduce principalmente por apomixis. El objetivo del presente trabajo es generar variabilidad genética, mediante cultivo in vitro, en caracteres asociados a tolerancia a sequía ... -
Alfalfa dwarf cytorhabdovirus P protein is a local and systemic RNA silencing supressor which inhibis program med RISC activity and prevents transitive amplification of RNA silencing
(2016)Plants employ RNA silencing as an innate defense mechanism against viruses. As a counter-defense, plant viruses have evolved to express RNA silencing suppressor proteins (RSS), which target one or more steps of the ... -
Genotypic variation in response to salinity in a new sexual germplasm of Cenchrus ciliaris L.
(2016)As part of breeding program for new salt- tolerant sexual genotypes of Cenchrus ciliaris L., we evaluated the salt- stress response of two new sexual hybrids, obtained by controlled crosses, at seedling and germination stages. -
Complete genome sequence of a new enamovirus from Argentina infecting alfalfa plants showing dwarfism symptoms
(2016)Alfalfa dwarf disease, probably caused by synergistic interactions of mixed virus infections, is a major and emergent disease that threatens alfalfa production in Argentina. Deep sequencing of diseased alfalfa plant samples ... -
FISH-mapping of the 5S rDNA locus in chili peppers (Capsicum-Solanaceae)
(2016)We present here the physical mapping of the 5S rDNA locus in six wild and fi ve cultivated taxa of Capsicum by means of a genus-specifi c FISH probe. In all taxa, a single 5S locus per haploid genome that persistently mapped ... -
Molecular detection of Thecaphora frezzi in peanut (Arachis Hypogaea L.) seeds
(2016)Thecaphora frezii is the causal agent of peanut smut, important disease in the Argentine production area. The pathogen can be dispersed by kernels, through surface contamination or small lesions. The aim of this work was ... -
Cytorhabdovirus P3 genes encode 30K-like cell-to-cell movement proteins
(2016)Plant viruses encode movement proteins (MP) to facilitate cell-to-cell transport through plasmodesmata. In this study, using trans-complementation of a movement-defective turnip vein-clearing tobamovirus (TVCV) replicon, ... -
Occurrence and characterization of a severe isolate of Watermelon mosaic virus from Argentina
(2016)More than 50 viruses have been reported in cucurbit crops worldwide. In Argentina, cucurbit viruses have been associated with important yield losses. The most prevalent and widespread potyvirus is Watermelon mosaic virus ... -
The 18S–25S ribosomal RNA unit of yerba mate (Ilex paraguariensis A. St.-Hil.)
(2016)We present the first report of the transcribed 18S–25S ribosomal DNA (rDNA) unit of the South American crop Ilex paraguariensis. This tree is consumed as an infusion named “mate”. Next-generation sequencing data were ... -
Genetic variability and recombination analysis of the coat protein gene of Strawberry mild yellow edge virus
(2016)Strawberry mild yellow edge virus (SMYEV) has been detected in most of the strawberry production regions worldwide. However, little is known about differences between distinct isolates. The aim of this study was to enhance ... -
Use of 454-Pyrosequencing for the characterization of Sweet potato virus C and Sweet Potato Feathery Mottle virus Isolates fron Argentina and Development of a Multiplex one - step RT-PCR for Their Simultaneous Detection
(2016)454-pyrosequencing was applied as a tool to identify etiological agents involved in the symptoms observed in a sweet potato sample from Argentina. RNA was purified from symptomatic material and sequenced using a Roche 454 ... -
First report of cowpea mild mottle virus in chia (Salvia hispanica)
