RABBIT EARS, encoding a SUPERMAN-like zinc finger protein, regulates petal development in Arabidopsis thaliana.
Floral organs usually initiate at fixed positions in concentric whorls within a flower. Although it is understood that floral homeotic genes determine the identity of floral organs, the mechanisms of position determination and the development of each organ have not been clearly explained. We isolated a novel mutant, rabbit ears (rbe), with defects in petal development. In rbe, under-developed p...
متن کاملRABBIT EARS regulates the transcription of TCP4 during petal development in Arabidopsis
Plant organ growth requires the proper transition from cell proliferation to cell expansion and differentiation. The CIN-TCP transcription factor gene TCP4 and its post-transcriptional regulator microRNA319 play a pivotal role in this process. In this study, we identified a pathway in which the product of the C2H2 zinc finger gene RABBIT EARS (RBE) regulates the transcription of TCP4 during Ara...
متن کاملNMR structure of the single QALGGH zinc finger domain from the Arabidopsis thaliana SUPERMAN protein.
Zinc finger domains of the classical type represent the most abundant DNA binding domains in eukaryotic transcription factors. Plant proteins contain from one to four zinc finger domains, which are characterized by high conservation of the sequence QALGGH, shown to be critical for DNA-binding activity. The Arabidopsis thaliana SUPERMAN protein, which contains a single QALGGH zinc finger, is nec...
متن کاملThe DnaJ-Like Zinc Finger Domain Protein PSA2 Affects Light Acclimation and Chloroplast Development in Arabidopsis thaliana
The biosynthesis of chlorophylls and carotenoids and the assembly of thylakoid membranes are critical for the photoautotrophic growth of plants. Different factors are involved in these two processes. In recent years, members of the DnaJ-like zinc finger domain proteins have been found to take part in the biogenesis and/or the maintenance of plastids. One member of this family of proteins, PSA2,...
متن کاملGene encoding a putative zinc finger protein in Synechocystis PCC6803.
A 5.5-kb HindIII fragment of Synechocystis PCC6803 containing a liverwort (ORF316) homolog encoding a putative zinc finger protein was cloned. Nucleotide sequence analysis showed that the homology of the amino acid sequence deduced from the ORF326 of Synechocystis PCC6803 with the counterparts of a liverwort and tobacco was 50% and 46%, respectively. Synechocystis ORF326 also showed 38% homolog...
