About 967 million reads and ... -
Genetic determinants of Vitamin C content in higher plants
Fenech-Torres, Mario; Amorim-Silva, Vitor; Smirnoff, Nicholas; Valpuesta-Fernandez, Victoriano; Botella-Mesa, Miguel Angel (2018-07-18)Ascorbic acid (AsA, VitC) is the most abundant water-soluble antioxidant in plants and it plays a plethora of biological roles including resistance to abiotic stress. Hence, including VitC as a trait to improve in breeding ... -
How are DGK1 and DGK2 involved in membrene contact sites?
Garía-Hernández, Selene; Ruiz López, Noemi; Botella-Mesa, Miguel Angel (Reunión Biología de Plantas Hispano Luso, 2021-07-07)Eukaryotic cells have regions of interaction between two organelles where some proteins, which act as tether, bring both membranes closer (10-30 nm) without fusion, named membrane contact sites (MCS). Two organelles that ... -
