Detection of the Ammonium Ion in Space

, 2013
We report on the detection of a narrow feature at 262816.73 MHz towards Orion and the cold prestellar core B1-bS, that we attribute to the 1(0)-0(0) line of the deuterated Ammonium ion, NH3D+.

Longevity in plants impacts phylogenetic and population dynamics

New Phytologist, EarlyView.
Summary Phylogenies of long‐lived plants often exhibit short molecular branch lengths and high levels of gene‐tree conflict. However, the biological mechanisms underlying these patterns remain unclear. We examine this with simulations and through empirical examination of several large seed plant clades.

RNA-Binding Proteins as Targets to Improve Salt Stress Tolerance in Crops

Agronomy, 2020
Salt stress drastically reduce crop productivity. In order to identify genes that could improve crop salt tolerance, we randomly expressed a cDNA library of the halotolerant sugar beet in a sodium-sensitive yeast strain.

Starch synthesis in Brachypodium distachyon endosperm occurs in dynamic, connected amyloplast compartments

New Phytologist, EarlyView.
Summary The morphology of starch granules is a major determinant of the functional and nutritional properties of starch and is highly variable among cereal species. Much of this morphological variation stems from differences in the spatial and temporal patterns of starch granule initiation in amyloplasts during grain development.

Nuclear Structure Calculations for Two-Neutrino Double-β Decay

Advances in High Energy Physics, 2016
We study the two-neutrino double-β decay in 76Ge, 116Cd, 128Te, 130Te, and 150Nd, as well as the two Gamow-Teller branches that connect the double-β decay partners with the states in the intermediate nuclei.

Discovery and characterizatopn of small molecular weight metallocarboxypeptidase inhibitors [PDF]

, 2010
Descripció del recurs: el 02 de novembre de 2010Las hidrolasas son enzimas que catalizan la ruptura del enlace amida o peptódico, y por lo tanto son denominadas también proteasas o peptidasas. Las proteasas constituyen cerca del 2 % del genoma humano, lo

New amphiphilic amino acid derivatives for efficient DNA transfection in vitro [PDF]

, 2017
Nucleic acids-based therapies have recently developed as next-generationagents for treating and preventing viral infection, cancer, and genetic disorders,but their use is still limited due to its relatively poor delivery into targetedcells.
