Higher order Arabidopsis 14-3-3 mutants show 14-3-3 involvement in primary root growth both under control and abiotic stress conditions
Arabidopsis 14-3-3 proteins are a family of conserved proteins that interact with numerous partner proteins in a phospho-specific manner, and can affect the target proteins in a number of ways; e.g. modification of enzymatic activity. We isolated T-DNA insertion lines in six 14-3-3 genes within the non-epsilon group that phylogenetically group in three closely related gene pairs. In total, 6 si...
متن کاملInvolvement of 14-3-3 protein GRF9 in root growth and response under polyethylene glycol-induced water stress.
Plant 14-3-3 proteins are phosphoserine-binding proteins that regulate a wide array of targets via direct protein-protein interactions. In this study, the role of a 14-3-3 protein, GRF9, in plant response to water stress was investigated. Arabidopsis wild-type, GRF9-deficient mutant (grf9), and GRF9-overexpressing (OE) plants were treated with polyethylene glycol (PEG) to induce mild water stre...
متن کاملThe Arabidopsis 14-3-3 multigene family.
The 14-3-3 proteins are ubiquitous eukaryotic proteins and are encoded by a gene family in many species. We examined the 14-3-3 gene family in Arabidopsis thaliana and found that it contains 10 members. Four new cDNAs, GF14 epsilon, GF14 kappa, GF14 mu, and GF14 nu, and two new genomic clones of GF14 phi and GF14 nu were isolated and characterized. Together with the six previously described 14-...
متن کاملThe rice 14-3-3 gene family and its involvement in responses to biotic and abiotic stress.
14-3-3 proteins function as major regulators of primary metabolism and cellular signal transduction in plants. However, their involvement in plant defense and stress responses is largely unknown. In order to better address functions of the rice 14-3-3/GF14 proteins in defense and abiotic stress responses, we examined the rice GF14 family that comprises eight numbers. The phylogenetic comparison...
متن کاملArabidopsis 14-3-3 Proteins: Fascinating and Less Fascinating Aspects
14-3-3 Dimers are well known to interact with diverse target proteins throughout eukaryotes. Most notably, association of 14-3-3s commonly requires phosphorylation of a serine or threonine residue within a specific sequence motif of the client protein. Studies with a focus on individual target proteins have unequivocally demonstrated 14-3-3s to be the crucial factors modifying the client's acti...
