Legacy of historic ozone exposure on plant community and food web structure
(Public Library of Science, 2017-08)
Information on whole community responses is needed to predict direction and magnitude of changes in plant and animal abundance under global changes. This study quantifies the effect of past ozone exposure on a weed community ...
Fuerzas armadas y militarización de los guardias nacionales en la frontera sur de Argentina (provincia de Buenos Aires, 1862-1879)Armed forces and militarization of the national guards on the southern border of Argentina (Buenos Aires province, 1862-1879)
(Universidad Complutense de Madrid, 2017-11)
En este artículo se examina cómo el Estado nacional argentino logró monopolizar el control de las fuerzas armadas en la frontera sur del país, a partir de analizar el aporte de cada una de ellas al sistema militar ...
Epstein-Barr virus down-regulates tumor suppressor DOK1 expression
(Public Library of Science, 2014-05)
The DOK1 tumor suppressor gene encodes an adapter protein that acts as a negative regulator of several signaling pathways. We have previously reported that DOK1 expression is up-regulated upon cellular stress, via the ...
Fungal endophytes help prevent weed invasions
(Elsevier, 2013-01)
This study tested whether the endophyte-promoted competitive superiority of forage grass can be used in biological weed control. Feasibility of endophytes in weed control was tested by manipulating endophyte colonization ...
DNA Topoisomerase 1α Promotes Transcriptional Silencing of Transposable Elements through DNA Methylation and Histone Lysine 9 Dimethylation in Arabidopsis
(Public Library Of Science, 2014-05)
RNA-directed DNA methylation (RdDM) and histone H3K9 dimethylation (H3K9me2) are related transcriptional silencing mechanisms that target transposable elements (TEs) and repeats to maintain genome stability in plants. RdDM ...
Kinetics and functional diversity among the five members of the NADP-malic enzyme family from Zea mays, a C4 species
(Springer, 2013-04)
NADP-malic enzyme (NADP-ME) is involved in different metabolic pathways in several organisms due to the relevant physiological functions of the substrates and products of its reaction. In plants, it is one of the most ...
Rab24 interacts with the Rab7/Rab interacting lysosomal protein complex to regulate endosomal degradation
(Wiley Blackwell Publishing, Inc, 2016-11)
Endocytosis is a multistep process engaged in extracellular molecules internalization. Several proteins including the Rab GTPases family coordinate the endocytic pathway. The small GTPase Rab7 is present in late endosome ...
