Beyond arabidopsis: differential UV-B response mediated by UVR8 in diverse species
(Frontiers Media, 2019-06)Ultraviolet-B radiation (UV-B, 280–315 nm) is an important environmental signal that regulates growth and development in plants. Two dose-dependent UV-B response pathways were described in plants: a specific one, mediated ... -
Male Sexual Behavior and Pheromone Emission Is Enhanced by Exposure to Guava Fruit Volatiles in Anastrepha fraterculus
(Plos One, 2015-04)Background: Plant chemicals can affect reproductive strategies of tephritid fruit flies by influencing sex pheromone communication and increasing male mating competitiveness. Objective and Methodology: We explored whether ... -
Complementary Sex Determination in the Parasitic Wasp Diachasmimorpha longicaudata
(Plos One, 2015-03)We studied the sex determination in Diachasmimorpha longicaudata, a parasitoid braconid wasp widely used as biological control agent of fruit pest tephritid flies. We tested the complementary sex determination hypothesis ... -
Candidate Gene Approach for Parasite Resistance in Sheep – Variation in Immune Pathway Genes and Association with Fecal Egg Count
(Plos One, 2014-02-12)Sheep chromosome 3 (Oar3) has the largest number of QTLs reported to be significantly associated with resistance to gastro-intestinal nematodes. This study aimed to identify single nucleotide polymorphisms (SNPs) within ... -
Ongoing speciation within the Anastrepha fraterculus cryptic species complex: the case of the Andean morphotype
(Wiley, 2014-09)The Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) cryptic species complex is currently composed of seven taxonomically recognized morphotypes. Both, pre‐ and post‐zygotic isolation has been documented among ... -
Plant chemicals and the sexual behavior of male tephritid fruit flies
(Oxford University Press, 2018-09)Plant compounds affect insects in many different ways. In addition to being a food source, plants also contain secondary metabolites that may have positive and negative impacts on insects. The influence of these compounds ... -
The origin and genetic diversity of the causal agent of Asian soybean rust, Phakopsora pachyrhizi, in South America
(Wiley, 2015-06)A sequence‐based approach was used to investigate molecular genetic variations in Phakopsora pachyrhizi, an obligate biotrophic pathogen that causes Asian soybean rust. In Argentina, the samples came from uredinium‐bearing ... -
LOV‐domain photoreceptor, encoded in a genomic island, attenuates the virulence of Pseudomonas syringae in light‐exposed Arabidopsis leaves
(Wiley, 2013-10)In Arabidopsis thaliana, light signals modulate the defences against bacteria. Here we show that light perceived by the LOV domain‐regulated two‐component system (Pst–Lov) of Pseudomonas syringae pv. tomato DC3000 (Pst ... -
Cryptic genetic structure in an Argentinian population of Anastrepha fraterculus (Diptera: Tephritidae) evidenced by SSR markers and quantitative traits
(Czech Academy of Sciences, 2019-04)In some regions of Argentina and Brazil, the South American fruit fly Anastrepha fraterculus (Wied.) (Diptera: Tephritidae) causes significant damage to crops. An efficient integrated management program requires knowledge ... -
Yeast derivatives and wheat germ in the adult diet modulates fecundity in a tephritid pest
(Cambridge University Press, 2019-04)Anastrepha fraterculus (Wiedemann), a pest of great economic importance in South America, needs urgently to be controlled by environmentally friendly methods such as the sterile insect technique for which mass rearing of ... -
Evolution of pre‐zygotic and post‐zygotic barriers to gene flow among three cryptic species within the Anastrepha fraterculus complex
(Wiley, 2013-09)Tropical tephritids are ideally suited for studies on population divergence and speciation because they include species groups undergoing rapid radiation, in which morphologically cryptic species and sister species are ... -
Response of the fruit fly parasitoid Diachasmimorpha longicaudata to host and host‐habitat volatile cues
(Wiley, 2012-05)Chemical information is crucial to insect parasitoids for successful host location. Here, we evaluated the innate response of Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae), a fruit fly larval parasitoid, ... -
Cooperativity in proton sensing by PIP aquaporins
(Wiley, 2019-03)One of the most intriguing properties of plasma membrane intrinsic protein (PIP) aquaporins (AQPs) is their ability to modulate water transport by sensing different levels of intracellular pH through the assembly of homo‐ ... -
In vivo and in vitro propagation of “macela”: a medicinal-aromatic native plant with ornamental potential
(Sociedade Brasileira de Floricultura e Plantas Ornmentais, 2018-12)Achyrocline satureioides is a shrub native from South America. In popular medicine it is used in infusions such as digestive, carminative, antispasmodic, eupeptic and emmenagogue. However, its main use is as an ingredient ... -
Plant growth-promoting genes can switch to be virulence factors via horizontal gene transfer
(Springer, 2018-10)There are increasing evidences that horizontal gene transfer (HGT) is a critical mechanism of bacterial evolution, while its complete impact remains unclear. A main constraint of HGT effects on microbial evolution seems ... -
Exploring the ancestral mechanisms of regulation of horizontally acquired nitrogenases
(Springer, 2015-10)The vast majority of Pseudomonas species are unable to fix atmospheric nitrogen. Although several studies have demonstrated that some strains belonging to the genus Pseudomonas sensu stricto do have the ability to fix ... -
