Redox regulation of auxin signaling and plant development in Arabidopsis.
Thioredoxin (NTR/TRX) and glutathione (GSH/GRX) are the two major systems which play a key role in the maintenance of cellular redox homeostasis. They are essential for plant development, cell division or the response to environmental stresses. In a recent article, we studied the interplay between the NADP-linked thioredoxin and glutathione systems in auxin signaling genetically, by associating...
متن کاملRedox regulation of plant homeodomain transcription factors.
Several families of plant transcription factors contain a conserved DNA binding motif known as the homeodomain. In two of these families, named Hd-Zip and glabra2, the homeodomain is associated with a leucine zipper-like dimerization motif. A group of Hd-Zip proteins, namely Hd-ZipII, contain a set of conserved cysteines within the dimerization motif and adjacent to it. Incubation of one of the...
متن کاملRedox regulation
he protein that does everything, 14–3-3, has now been shown to direct traffic. Ita O'Kelly, Steve Goldstein, and colleagues (Yale University, New Haven, CT) find that 14–3-3 can displace -COP from various proteins, thus freeing them from retention in the ER and leading to surface expression. Goldstein set out to find proteins interacting with the COOH terminus of a K ϩ leak channel, KCNK3, and...
متن کاملPlant development: regulation by protein degradation.
Many aspects of eukaryotic development depend on regulated protein degradation by the ubiquitin-proteasome pathway. This highly conserved pathway promotes covalent attachment of ubiquitin to protein substrates through the sequential action of three enzymes called a ubiquitin-activating enzyme (E1), a ubiquitin-conjugating enzyme (E2), and a ubiquitin-protein ligase (E3). Most ubiquitinated prot...
متن کاملPlant development regulation: Overview and perspectives.
Plant development, as occur in other eukaryotes, is conducted through a complex network of hormones, transcription factors, enzymes and micro RNAs, among other cellular components. They control developmental processes such as embryo, apical root and shoot meristem, leaf, flower, or seed formation, among others. The research in these topics has been very active in last decades. Recently, an expl...
