Arabidopsis DNA glycosylase MBD4L improves recovery of aged seeds
(Wiley, 2024-07-04)DNA glycosylases initiate the base excision repair (BER) pathway by catalyzing the removal of damaged or mismatched bases from DNA. The Arabidopsis DNA glycosylase methyl-CpG-binding domain protein 4 like (MBD4L) is a ... -
Ecophysiological mechanisms underlying the positive relationship between seed protein concentration and yield in soybean under field heat and drought stress
(Wiley, 2024-06)A positive relationship between protein concentration and yield has been documented in different combinations of genotype and environment, often under potential conditions. However, the ecophysiological bases underlying ... -
Los bioinsumos en el mundo forestal: ¿mejoran el crecimiento en vivero de plantas de algarrobo blanco?
(Colegio de Graduados en Ciencias Forestales de Santiago de Estero, 2023)¿Qué es un bioinsumo?, es una pregunta necesaria para poder comprender que se trata de aquellos productos de origen biológico (vegetal, animal o microbiano) usados para mejorar la productividad, sanidad o tolerancia al ... -
Respuesta micorrícica a la aplicación de inóculos de hongos micorrícicos arbusculares nativos en simbiosis con Neltuma alba = Mycorrhizal response to the application of inoculums of arbuscular mycorrhizal fungi native in symbiosis with Neltuma alba
(Facultad de Ciencias Forestales, Universidad Nacional de Santiago del Estero, 2023-12-22)Neltuma alba es un importante recurso forestal en Argentina debido a sus múltiples usos, motivo por el cual ha sido sobreexplotada.
