| Title | Rice <i>TSV3</i> Encoding Obg-Like GTPase Protein Is Essential for Chloroplast Development During the Early Leaf Stage Under Cold Stress. | |
|
Abstract: 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 (<i>Oryza sativa</i> L.) <i>thermo-sensitive virescent</i> mutant (<i>TSV3</i>) that displayed an albino phenotype at 20° before the three-leaf stage while being a normal green at 32° or even at 20° after the four-leaf stage. The mutant phenotype was consistent with altered chlorophyll content and chloroplast structure in leaves. Map-based cloning and complementation experiments showed that <i>TSV3</i> encoded a small GTP-binding protein. Subcellular localization studies revealed that TSV3 was localized to the chloroplasts. Expression of <i>TSV3</i> was high in leaves and weak or undetectable in other tissues, suggesting a tissue-specific expression of <i>TSV3</i> In the <i>TSV3</i> mutant, expression levels of genes associated with the biogenesis of the chloroplast ribosome 50S subunit were severely decreased at the three-leaf stage under cold stress (20°), but could be recovered to normal levels at a higher temperature (32°). These observations suggest that the rice nuclear-encoded <i>TSV3</i> plays important roles in chloroplast development at the early leaf stage under cold stress. |
