Ammonium stress increases microautophagic activity while impairing macroautophagic flux in Arabidopsis roots
(Wiley, 2020-11-22)Plant responses to NH4 + stress are complex, and multiple mechanisms underlying NH4 + sensitivity and tolerance in plants may be involved. Here, we demonstrate that macro‐ and microautophagic activities are oppositely ... -
An Autophagy-Related Kinase Is Essential for the Symbiotic Relationship between Phaseolus vulgaris and Both Rhizobia and Arbuscular Mycorrhizal Fungi
(American Society of Plant Biologists, 2016-09)Eukaryotes contain three types of lipid kinases that belong to the phosphatidylinositol 3-kinase (PI3K) family. In plants and Saccharomyces cerevisiae, only PI3K class III family members have been identified. These enzymes ... -

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 ... -
Are Sunflower chlorotic mottle virus infection symptoms modulated by early increases in leaf sugar concentration?
(Elsevier, 2010-09-15)Symptom development in a susceptible sunflower line inoculated with Sunflower chlorotic mottle virus (SuCMoV) was followed in the second pair of leaves at different post-inoculation times: before symptom expression (BS), ... -
Assessing spatial genetic structure from molecular marker data via principal component analyses: a case study in a Prosopis sp. fores
(Scientific Research Publishing, 2014-01)Advances in genotyping technology, such as molecular markers, have noticeably improved our capacity to characterize genomes at multiple loci. Concomitantly, the methodological framework to analyze genetic data has expanded, ... -
Assessment of genetic and epigenetic changes in virus-free garlic (Allium sativum L.) plants obtained by meristem culture followed by in vitro propagation
(2016-01)Garlic (Allium sativum) is a worldwide crop of economic importance susceptible to viral infections that can cause significant yield losses. Meristem tissue culture is the most employed method to sanitize elite cultivars. ... -
Assessment of lead tolerance on Glycine max (L.) Merr. at early growth stages
(Springer, 2021-01-11)Lead (Pb) contamination of agricultural soils, and subsequently of crops, has been widely reported. Soybean (Glycine max (L.) Merr.) has been indicated as a plant that accumulates Pb, even in soils that do not exceed the ... -
Bacillus subtilis ALBA01 alleviates onion pink root by antagonizing the pathogen Setophoma terrestris and allowing physiological status maintenance
(Springer, 2020)The soil-borne pathogen Setophoma terrestris is the causal agent of pink root of onion, one of the most challenging diseases in onion production. Conventional approaches for managing the disease like solarization, soil ... -
A bacterial endophyte from apoplast fluids protects canola plants from different phytopathogens via antibiosis and induction of host resistance
(American Phytopathological Society, 2019-03)Endophytic bacteria colonize inner plant tissues and thrive at the apoplast, which is considered its main reservoir. Because this niche is the place where the main molecular events take place between beneficial and pathogenic ... -
Benchmarking Nutraceutical Soybean Composition Relative to Protein and Oil
(Frontiers Media, 2021-08-11)The aim of this study was to explore relationships between protein, oil, and seed weight with seed nutraceutical composition, focused on total isoflavone (TI) and total tocopherol (TT) contents across genotypic and ... -
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 ... -
