Exogenous Gibberellins Induce Wheat Spike Development under Short Days Only in the Presence of VERNALIZATION1 por Pearce, Stephen, Vanzetti, Leonardo Sebastian, Dubcovsky, Jorge

“…Based on these observations, we propose a model in which FLOWERING LOCUS T is up-regulated in the leaves under LDs and is then transported to the shoot apical meristem, where it simultaneously induces the expression of VRN1 and GA biosynthetic genes, which are both required for the up-regulation of the early floral meristem genes SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1-1 and LEAFY and the timely development of the wheat spike.…”

Synergy between glyphosate- and cypermethrin-based pesticides during acute exposures in tadpoles of the common South American Toad Rhinella arenarum por Brodeur, Celine Marie Julie, Poliserpi, Maria Belen, D'Andrea, María Florencia, Sanchez, Marisol

“…The magnitude of the synergy (factor by which toxicity differed from concentration addition) was constant at around twofold for all tested proportions of the glyphosate Glifoglex + cypermethrin Glextrin mixture; whereas the magnitude of the synergy varied between 4 and 9 times in the glyphosate Glifosato Atanor + cypermethrin Xiper mixture. …”

Oral acute toxicity of imidacloprid, thiamethoxam and clothianidin in eared doves: a contribution for the risk assessment of neonicotinoids in birds por Addy Orduna, Laura, Brodeur, Celine Marie Julie, Mateo Soria, Rafael

“…Imidacloprid also differed from the other two neonicotinoids in terms of the onset and intensity of intoxication signs and the times of death and recovery. All three insecticides induced a reduction in food consumption that led to body weight loss. …”

Estimating the protection afforded by foot-and-mouth disease vaccines in the laboratory por Paton, D. J., Reeve, R., Capozzo, Alejandra Victoria, Ludi, A.

“…Antibody-virus interactions may vary between virus serotypes and strains and protection may be affected by the vaccination regime and the nature and timing of field virus challenge. Finally, tests employing biological reagents are difficult to standardise, whilst cross-protection data needed for test calibration and validation are scarce. …”

Diversity of floral regulatory genes of japonica rice cultivated at northern latitudes por Naranjo, Laura, Talón, Manuel, Domingo, Concha

“…The existence of non-functional Hd1 alleles and the lack of correlation of their presence with flowering times in plants grown under long day conditions, indicate a minor role of this branch in this process and the existence of an alternative regulatory pathway in northern latitudes. …”

Non-destructive assessment of chloride in persimmon leaves using a miniature visible near-infrared spectrometer por Visconti, Fernando, De-Paz, José M.

“…To study the feasibility of such models, a persimmon orchard was grown in E Spain and irrigated with eight waters ranging in Cl− concentration from 70 to 350 mg/L. Then, six times throughout the growing season the Vis-NIR foliar reflectance spectra of various representative leaves per Cl− treatment were recorded with a portable miniature Vis-NIR spectrometer. …”

Exclusion of ground-nesting ants promotes biological control, but facilitates the establishment of an exotic canopy-nesting ant species por Plata, Ángel, Gómez-Martínez, María A., Beitia, Francisco J., Tena, Alejandro

“…This ant species established its colonies under the sepals of persimmon fruit, and its abundance increased by more than 10 times in trees with physical barriers. Our results show that the exclusion of native ground-nesting from fruit trees can promote the control of invasive mealybugs, but may also facilitate the establishment and spread of exotic canopy-nesting ant species, hence increasing their invasive potential. …”

Forecast models of coffee leaf rust symptoms and signs based on identified microclimatic combinations in coffee-based agroforestry systems in Costa Rica por Merle, Isabelle, Tixler, Philippe, Virginio Filho, Elias de Melo, Cilas, Christian, Avelino, Jacques

“…However, the appearance of a symptom or sign can be influenced by complex combinations of meteorological variables acting at different times and for different durations. In our study, we monitored a total of 5400 coffee leaves during a year and a half, in different agroforestry systems, in order to detect the onset dates of the disease symptoms, such as lesion emergence, and signs, such as sporulation and infectious area increase. …”
