The CGIAR at a crossroads: assessing the role of international agricultural research in poverty alleviation from an innovation systems perspective por Ekboir, Javier M.

“…These capabilities should refer not only to scientific research but also to new ways to support innovation and to design and implement poverty-alleviation programs. Finally, CGIAR researchers should adopt new research methods to better integrate into local and international innovation networks.…”

Utilization of tissue culture techniques for the conservation and international exchange of cassava (Manihot esculenta) germplasm por Roca, W., Narvaez, J, Rodríguez, J., Reyes, R., Mafla, G., Beltrán, J., Roa E, Julio César, Ramírez, H., Rodríguez, A.M.

“…With the exception of variation in the color of root epidermis and cortex, no changes resulted solely from in vitro storage in any of the morphological, agronomic, and biochemical characters evaluated. Finally the use of a modified Murashige and Skoog medium, supplemented with GA, thiourea, and sucrose, to achieve embryo germination and plant development in 10 wild Manihot spp., is reported. …”

Statistical selection: Main approaches and a modification with a preference threshold por Coolen, Franciscus Petrus Antonius, Laan, P. van der

“…A short review is given on the use of a loss function as a generalization of selection of an épsilon-best treatment is a generalization of a best treatment and is defined as a treatment on a "distance" less than épsilon of the best treatment. Finally, a generalization of the concept of the Indifference Zone selection is presented. …”

Expanding the benefits of Tnt1 for the identification of dominant mutations in polyploid crops: A single allelic mutation in the MsNAC39 gene produces multifoliated alfalfa por Jozefkowicz, Cintia, Gomez, Maria Cristina, Odorizzi, Ariel, Iantcheva, Anelia, Ratet, Pascal, Ayub, Nicolás Daniel, Soto, Gabriela Cynthia

“…Specifically, we show that a single allelic mutation in the MsNAC39 gene produces multifoliate leaves (mfl) alfalfa plants, a pivot trait of breeding programs of this forage species. Finally, we discuss the potential application of a combination of preliminary screening of beneficial dominant mutants using Tnt1 mutant libraries and genome editing via the CRISPR/Cas9 system to identify target genes and to rapidly improve both autogamous and allogamous polyploid crops.…”

The Gln15Arg mutation in the transcriptional factor PALM1 produces multifoliate alfalfa por Gomez, Maria Cristina, Jozefkowicz, Cintia, Mozzicafreddo, Matteo, Odorizzi, Ariel, Arolfo, Valeria, Basigalup, Daniel Horacio, Ayub, Nicolás Daniel, Soto, Gabriela Cynthia

“…Specifically, we showed that the mutation of the conserved glutamine 15 of the transcriptional factor PALM1 to arginine produces heptafoliate leaves in alfalfa, improving its digestibility and nutritional quality. Finally, we discuss the potential use of this mutation to rapidly generate transgenic-free legume forages with higher nutritional value via adenine base editors.…”

Cómo guardar granos húmedos sin perder calidad por Roskopf, Rubén Darío, De La Torre, Diego

“…El temporal de lluvia, que comenzó a finales de abril y se extendió hasta comienzos de mayo en algunas regiones, provocó la interrupción de las labores de trilla y la aparición de serios problemas vinculados con alta humedad de granos como la presencia de brotado, dehiscencia, enfermedades y disminuciones en el peso específico. …”

Following the star: Inflorescence heliotropism por Serrano, Alejandro M., Arana, María Veronica, Vanhaelewyn, Lucas, Ballare, Carlos Luis, Van Der Straeten, Dominique, Vandenbussche, Filip

“…In addition, we discuss the mechanisms underlying different types of heliotropism in two species commonly used as model systems: Arabidopsis and sunflower. Finally, the ecological consequences of floral heliotropism are elaborated with an emphasis on the effects on plant reproductive success, and the potential agricultural implications of manipulating heliotropic responses are addressed as well. …”

Antioxidant characterization of new dietary fiber concentrates from papaya pulp and peel (Carica papaya L.) por Nieto Calvache, Jhon, Cueto, Mario Alberto, Farroni, Abel Eduardo, Escalada Pla, Marina de, Gerschenson, Lia Noemi

“…Likewise, lutein, zeaxanthin, β-carotene and β-criptoxanthin were identified and quantified by HPLC. Finally, an analysis of digestibility showed that about 65% of the polyphenols associated to pulp and peel DFCs were potentially bioaccessible in the small intestine and that the portion of indigestible fiber had antioxidant capacity. …”

Sensibilidad varietal del olivo a la tuberculosis causada por Pseudomonas savastanoi pv. savastanoi por Penyalver, Ramón, Garcia, Amparo, Del Río, C., Caballero, J. M., Pinochet, J., Piquer, J., López, María M.

“…La tuberculosis del olivo, enfermedad también conocida como roña fue ya descrita por Theophrastus 400 años antes de Cristo, pero hasta finales del siglo XIX no se sospechó su etiología bacteriana. …”

Importance of ground-dwelling predators on controlling 'Ceratitis capitata 'in Spanish citrus orchards por Monzó, César, Sabater-Munoz, Beatriz, García, José L., Urbaneja, Alberto, Castanera, Pedro

“…Moreover, functional response parameters against this prey were also obtained. Finally, preydetection tools (molecular markers and immuno-assays) are being developed to establish the role of those predators in the control of C. capitata under field conditions.…”

Modulation of Dormancy and Growth Responses in Reproductive Buds of Temperate Trees por Lloret, Alba, Badenes, María L., Ríos, Gabino

“…Stress tolerance, dormancy, and flowering processes are thus physically and temporarily restricted to a bud, and consequently forced to interact at the regulatory level.We review recent genomic, genetic, and molecular contributions to the knowledge of these three processes in trees, highlighting the role of epigenetic modifications, phytohormones, and common regulatory factors. Finally, we emphasize the utility of transcriptomic approaches for the identification of key structural and regulatory genes involved in bud processes, illustrated with our own experience using peach as a model.…”

Boletín Agroclimático Regional: mesa técnica agroclimática de Sucre julio 2025

“…Los modelos de predicción climática indican una probabilidad de 67% de que estas condiciones neutrales continúen durante el trimestre julio-septiembre. Aunque hacia finales del año aumenta la incertidumbre, el escenario más probable sigue siendo la continuidad de la fase neutral, lo puede favorecer las lluvias si se aporta humedad de otros sistemas.…”

Relación entre el ataque de nemátodos y la muerte súbita del cacao (Theobroma cacao L.) en Bahia, Brasil por Jiménez Sáenz, E.

“…Although circumstantial, this evidence strongly suggests that they origin of the so-called “morte súbita” is closely associated to the attack of plant parasitic nematodes, which destroy the feeding roots and eventually kill the plant. Finally, the other recommends, among other things, that further research should be performed in order to prove the suspected relationship between the injury caused by the root-knot and/or the root-lesion nematodes and the “sudden death” of the cacao tree.…”
