Rice TSV3 Encoding Obg-Like GTPase Protein Is Essential for Chloroplast Development During the Early Leaf Stage Under Cold Stress
The Spo0B-associated GTP-binding (Obg) proteins are essential for the viability of nearly all bacteria. However, the detailed roles of Obg proteins in higher plants have not yet been elucidated. In this study, we identified a novel rice (Oryza sativa L.) thermo-sensitive virescent mutant (tsv3) that displayed an albino phenotype at 20° before the three-leaf stage while being a normal green at 3...
متن کاملEstablishment of the chloroplast genetic system in rice during early leaf development and at low temperatures
Chloroplasts are the central nodes of the metabolic network in leaf cells of higher plants, and the conversion of proplastids into chloroplasts is tightly coupled to leaf development. During early leaf development, the structure and function of the chloroplasts differ greatly from those in a mature leaf, suggesting the existence of a stage-specific mechanism regulating chloroplast development d...
متن کاملArabidopsis OBG-like GTPase (AtOBGL) is localized in chloroplasts and has an essential function in embryo development.
OBG-like GTPases, a subfamily of P-loop GTPases, have divers and important functions in bacteria, including initiation of sporulation, DNA replication, and protein translation. Homologs of the Bacillus subtilis spo0B GTP-binding protein (OBG) can be found in plants and algae but their specific function in these organisms has not yet been elucidated. Here, it is shown that AT5G18570 encodes an A...
متن کاملSpecific expression of the chloroplast gene for RNA polymerase (rpoB) at an early stage of leaf development in rice.
The rpoB gene for the beta subunit of rice chloroplast RNA polymerase was found to be highly expressed in unexpanded immature leaves that contained proplastids, indicating the specific expression of rpoB at an early stage of chloroplast development. A putative transcription start site (tss) was identified, but the 5' upstream region of the tss had no sequences resembling typical --35 and --10 e...
متن کاملTargeting an Essential GTPase Obg for the Development of Broad-Spectrum Antibiotics.
A promising new drug target for the development of novel broad-spectrum antibiotics is the highly conserved small GTPase Obg (YhbZ, CgtA), a protein essential for the survival of all bacteria including Neisseria gonorrhoeae (GC). GC is the agent of gonorrhea, a prevalent sexually transmitted disease resulting in serious consequences on reproductive and neonatal health. A preventive anti-gonorrh...
