Variability of plum pox virus populations in ppv-resistant transgenic and non-transgenic plums
Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Capote, Nieves, Cambra, Mariano
To determine the resistance to PPV in natural conditions, transgenic plums
(Prunus domestica) carrying the coat protein gene of Plum pox virus (PPV) were established
in the open field in Valencia, Spain in 1997. To assess the environmental impact
that the release of transgenic plums to the field has on the dynamic and
diversity of virus population, the variability of PPV populations present in transgenic
vs. non-transgenic plums was compared. Serological and molecular characterisation
of the…

Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Martínez-Alcántara, Belén, Quinones, Ana, Polo, Carolina, Primo-Millo, Eduardo, Legaz, Francisco
In citrus orchards, nitrogen uptake efficiency (NUE) is between 40 to 60% where any excess of nitrate is subjected to leaching below the rooting zone. The compound, 3,4-dimethylpyrazole phosphate (DMPP) inhibits the nitrification process in soil thus reducing/delaying nitrate leaching. The objective of this study was to evaluate the performance of DMPP added to ammonium sulphate (AS+DMPP), compared to ammonium sulphate (AS) and calcium-potassium nitrate (CPN), in fertigation of bearing orange…

Cooling of goat buck sperm in refrigerated bath or in itinere: effects on in vitro sperm quality
Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Mocé, Eva, Lozano-Palazón, Salvador A., López, I., Martínez-Granell, María M., Bernacer, José, Vicente, Carlos, Gómez, Ernesto A.
Goat buck sperm doses are kept at 4°C in refrigerated form. As a cold‐shock sensitive species, chilling to 4°C must be slow, which delays the doses delivery and their insemination. However, the time of transportation could be used for chilling. We studied if the sperm quality was similar between a system developed for chilling the doses during transportation and the programmable water bath (WB) in the lab. Twelve Murciano‐Granadina bucks were used. The concentration in each ejaculate (n = 12)…

Organ abscission is an important process in plant development and reproduction. During abscission, changes in cellular adhesion of specialized abscission zone cells ensure the detachment of infected organs or those no longer serving a function to the plant. In addition, abscission also plays an important role in the release of ripe fruits. Different plant species display distinct patterns and timing of organ shedding, most likely adapted during evolution to their diverse life styles. However,…

Ruiz, Marta, Quinones, Ana, Martínez-Alcántara, Belén, Aleza, Pablo, Morillon, Raphael, Navarro, Luis, Primo-Millo, Eduardo, Martínez-Cuenca, Mary-Rus
Tetraploidy modifies root anatomy which may lead to differentiated capacity to uptake
and transport mineral elements. This work provides insights into physiological and
molecular characters involved in boron (B) toxicity responses in diploid (2x) and
tetraploid (4x) plants of Carrizo citrange (Citrus sinensis L. Osb. Poncirus trifoliata L.
Raf.), a widely used citrus rootstock. With B excess, 2x plants accumulated more B
in leaves than 4x plants, which accounted for their higher B uptake and…

Multiplex real-time PCR for detection and quantification of Colletotrichum abscissum and C. gloeosporioides on Citrus leaves
Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Pereira, W. V., Bertolini, Edson, Cambra, Mariano, Massola Junior, N. S.
Colletotrichum abscissum and C. gloeosporioides are the causal agents of citrus Postbloom Fruit Drop (PFD), a major disease in several countries of the American continent. These pathogens infect only floral structures; however, in the absence of floral tissue, they survive asymptomatically on the leaf tissue. Thus, detecting and quantifying pathogens on leaves are critical for epidemiological studies. Colletotrichum species are detected through isolation, serological methods and conventional…

A single injection of corifollitropin alfa supplemented with human chorionic gonadotropin increases follicular recruitment and transferable embryos in the rabbit
Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Viudes-De-Castro, María P., Marco-Jiménez, Francisco, Más Pellicer, Alba, García-Domínguez, Ximo, Talavan, Amparo, Salvador Vicente, José
Superovulation protocols are designed to achieve maximum embryo yields. Nevertheless, ovarian response control and the quality of obtained embryos are still a challenge. On the other hand, to save the superovulated embryos until their subsequent use, it is usual to cryopreserve them, so it is also crucial to assess their cryotolerance. The aim of this study was to compare the efficacy of a single injection of corifollitropin alfa (FSH‐CTP) alone or supplemented with human chorionic gonadotropin…

Chloride regulates leaf cell size and water relations in tobacco plants
Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Franco-Navarro, Juan D., Brumos, Javier, Rosales, Miguel A., Cubero-Font, Paloma, Talón, Manuel, Colmenero-Flores, José M.
Chloride (Cl–) is a micronutrient that accumulates to macronutrient levels since it is normally available in nature and
actively taken up by higher plants. Besides a role as an unspecific cell osmoticum, no clear biological roles have been
explicitly associated with Cl– when accumulated to macronutrient concentrations. To address this question, the glycophyte
tobacco (Nicotiana tabacum L. var. Habana) has been treated with a basal nutrient solution supplemented
with one of three salt…

Can interactions among predators alter the natural regulation of an herbivore in a climate change scenario? The case of Tetranychus urticae and its predators in citrus
Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Urbaneja-Bernat, Pablo, Ibanez, Victoria, Montserrat, Marta, Aguilar-Fenollosa, Ernestina, Jaques, Josep A.
Climate change can dramatically affect the food web configuration of arthropod communities through its effects on species interactions. We have studied whether these effects could alter the probability of local extinction of three predatory mites naturally associated with the two spotted spider mite, Tetranychus urticae, in citrus in Spain and, therefore, disrupt the biological control of this phytophagous mite. Laboratory and semi-field results provide evidence that the natural regulation of T…

Residual toxicity of insecticides used against the Asian citrus psyllid and resistance management strategies with thiamethoxam and abamectin
Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Vanaclocha, Pilar, Jones, Moneen M., Tansey, James A., Monzó, César, Chen, Xulin, Stansly, Philip A.
The Asian citrus psyllid (ACP) is the key pest of citrus due to its role as vector of huanglongbing. ACP control mostly relies on frequent insecticide applications therefore increasing selection for insecticide resistance. Optimization of field application rates and rotation of insecticide modes of action (MoA) would minimize this risk. Baseline toxicity responses of ACP to commonly used insecticides provide a basis for defining application field rates and are thus needed to track potential…

Conde, Daniel, Perales, Mariano, Sreedasyam, Avinash, Tuskan, Gerald A., Lloret, Alba, Badenes, María L., González-Melendi, Pablo, Ríos, Gabino, Allona, Isabel
In temperate and boreal regions, perennial trees arrest cell division in their meristematic tissues during winter dormancy until environmental conditions become appropriate for their renewed growth. Release from the dormant state requires exposure to a period of chilling temperatures similar to the vernalization required for flowering in Arabidopsis. Over the past decade, genomic DNA (gDNA) methylation and transcriptome studies
have revealed signatures of chromatin regulation during active…

A multihost bacterial pathogen overcomes continuous population bottlenecks to adapt to new host species
Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Bacigalupe, Rodrigo, Tormo-Mas, María A., Penadés, José R., Fitzgerald, J. Ross
While many bacterial pathogens are restricted to single host species, some have the capacity to undergo host switches,
leading to the emergence of new clones that are a threat tohuman and animal health. However, the bacterial traits that
underpin a multihost ecology are not well understood. Following transmission to a new host, bacterial populations are
influenced by powerful forces such as genetic drift that reduce the fixation rate of beneficial mutations, limiting the
capacity for host…

Alternation of wet and dry sides during partial rootzone drying irrigation enhances leaf ethylene evolution
Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Pérez-Pérez, Juan G., Puertolas, Jaime, Albacete, Alfonso, Dodd, Ian C.
Soil drying increases endogenous ABA and ACC concentrations in planta, but how these compounds interact to regulate stomatal responses to soil drying and re-watering is still unclear. To determine the temporal dynamics and physiological significance of root, xylem and leaf ABA and ACC concentrations in response to deficit irrigation (DI) or partial rootzone drying (PRD-F) and re-watering, these variables were measured in plants exposed to similar whole pot soil water contents. Both DI and PRD-F…

Multiple stresses occurring with boron toxicity and deficiency in plants
Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
García-Sánchez, Francisco, Simón-Grao, Silvia, Martínez-Nicolás, Juan J., Alfosea-Simón, Marina, Liu, Chunguang, Chatzissavvidis, C., Pérez-Pérez, Juan G., Cámara-Zapata, Jose M.
Boron (B), an essential nutrient for plants, participates in many physiological processes, with emphasis its role in the formation of the plant’s cell wall. In soil, the range between deficiency and toxicity of B is very narrow as compared to other nutrients, which makes its management in agriculture very difficult, as it depends on the soil and environmental conditions. B stress simultaneously acts with others (extreme temperatures, excess of light, high concentration of CO2, drought, salinity…

Short-term response of young mandarin trees to desalinated seawater irrigation
Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Maestre-Valero, José F., Martínez-Álvarez, Victoriano, Jódar-Conesa, Francisco J., Acosta, Jose A., Martín-Gorriz, Bernardo, Robles, Juan M., Pérez-Pérez, Juan G., Navarro, Josefa M.
Water deficit and increasing pressure on water resources in semi-arid regions has led to the spread of irrigation with non-conventional water resources, such as desalinated seawater (DSW). The few existent studies to date, mainly carried out in Israel and Spain, have shown that suitable management of irrigation with DSW must be performed to avoid agronomic problems and reductions in crop productivity and fruit quality in the mid-long term. To the best of our knowledge, in the case of citrus,…

Self-(In)compatibility Systems: Target Traits for Crop-Production, Plant Breeding, and Biotechnology
Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Munoz-Sanz, Juan V., Zuriaga, Elena, Cruz-García, Felipe, McClure, Bruce, Romero, Carlos
Self-incompatibility (SI) mechanisms prevent self-fertilization in flowering plants based on
specific discrimination between self- and non-self pollen. Since this trait promotes outcrossing
and avoids inbreeding it is a widespread mechanism of controlling sexual plant reproduction.
Growers and breeders have effectively exploited SI as a tool for manipulating domesticated
crops for thousands of years. However, only within the past thirty years have studies begun to
elucidate the underlying…

Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Martínez-Andújar, Cristina, Albacete, Alfonso, Martínez-Pérez, Ascensión, Pérez-Pérez, José Manuel, Asins, María J., Pérez-Alfocea, Francisco
Selection and breeding of rootstocks that can tolerate low K supply may increase crop productivity in low fertility soils and reduce fertilizer application. However, the underlying physiological traits are still largely unknown. In this study, 16 contrasting recombinant inbred lines (RILs) derived from a cross between domestic and wild tomato species (Solanum lycopersicum × Solanum pimpinellifolium) have been used to analyse traits related to the rootstock-mediated induction of low (L, low…

The persistent southern tomato virus modifies miRNA expression without inducing symptoms and cell ultra-structural changes
Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Elvira-González, Laura, Medina, Vicente, Rubio, Luis, Galipienso, Luis
Southern tomato virus (STV) is a double-stranded RNA virus (genus Amalgavirus, family Amalgaviridae) with a persistent lifestyle, transmitted only vertically by seed. STV is widely distributed showing a high incidence in tomato crops from different production regions. Acute viruses usually induce plant development and cell ultra-structural changes related to the production of plant symptoms. Some of these changes are the consequence of alterations in the expression of endogenous plant microRNAs…

Genetic inhibition of flowering differs between juvenile and adult Citrus trees
Repositorio: ReDivia Repositorio Digital del Instituto Valenciano de Investigaciones Agrarias
Munoz-Fambuena, Natalia, Nicolás-Almansa, M., Martínez-Fuentes, Amparo, Reig, Carmina, Iglesias, Domingo J., Primo-Millo, Eduardo, Mesejo, Carlos, Agustí, Manuel
Background and Aims
In woody species, the juvenile period maintains the axillary meristems in a vegetative stage, unable to flower, for several years. However, in adult trees, some 1-year-old meristems flower whereas others remain vegetative to ensure a polycarpic growth habit. Both types of trees, therefore, have non-flowering meristems, and we hypothesize that the molecular mechanism regulating flower inhibition in juvenile trees is different from that in adult trees.
Methods
In adult Citrus…
