Environmental influence on reproductive traits of buffel grass facultative apomictic genotypes and its implication in plant breeding
(Wiley, 2023-10-04)Cenchrus ciliaris L., a perennial C4 grass, is one of the most widely used forage species in warm and dry regions worldwide. The widespread use of the cultivar Texas raises concerns about genetic homogeneity and vulnerability. ... -
Los extractos vegetales como artefacto tecnológico para la transición agroecológica: experiencias de prueba en Córdoba, Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional del Litoral, 2023-07-06)Este artículo analiza dos Marcos Tecnológicos en disputa vigentes en la Región Agroalimentaria de Córdoba Centro: el convencional (MTC), con una presencia dominante en el sector agropecuario y el agroecológico (MTAE), con ... -
The Arabidopsis chromatin regulator MOM1 is a negative component of the defense priming induced by AZA, BABA and PIP
(Frontiers Media, 2023-05-09)In plants, the establishment of broad and long-lasting immunity is based on programs that control systemic resistance and immunological memory or “priming”. Despite not showing activated defenses, a primed plant induces a ... -
Cytogenetic evidence of hybridization in Prosopis alba, P. hassleri, and P. fiebrigii in the semiarid-humid Chaco transition
(Taylor and Francis, 2023-06-06)Hybridization is a common and widespread phenomenon in vascular plants, leading to genetic exchange between related species. Interspecific hybridization has been extensively reported in Prosopis, a key genus of the Gran ... -
Editorial: Legumes and their microbiome in climate change mitigation
(Frontiers Media, 2023-06-12)Climate change accelerates or enhances the incidence of a variety of abiotic and biotic stresses on agricultural and forest productivity. By changing different aspects of agriculture management, we can lower the risk of ... -
