(Universidad de Chile, 2023)Los líquenes consisten en asociaciones simbióticas entre un hongo (micobionte) y uno o dos organismos fotosintéticos (fotobionte/s) que pueden ser un alga verde y/o una cianobacteria. Además, se ha descrito la presencia ...
-
(Taylor and Francis, 2016)Autophagy is mainly regulated by post-translational and lipid modifications of ATG proteins. In some scenarios, the induction of autophagy is accompanied by increased levels of certain ATG mRNAs such as MAP1LC3B/LC3B, ATG5 ...
-
(México Federación Latinoamericana de Química, 1990)The leaves of P. glandulosa contain the active meroterpenoid bakuchiol, as well as angelicin, psoralen and a new cinnamic derivative.
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2002-09)Sulphur distribution with an insight in S-organic fractions was studied in volcanic-ash derived soils of Chile (Typic Dystrandepts, Palehumult) by isolating each fraction and measuring S directly by instrumental elemental ...
-
(Temuco, Chile, Universidad de la Frontera, Facultad de Ciencias Agropecuarias, 1999)En los suelos evaluados en este estudio junto con la determinación de la dinámica del carbono y la actividad biológica se determinó el status de algunos macroelementos esenciales. Entre los nutrientes de importancia se ...
