dc.description.abstract | The longevity of plant leaf organs is genetically determined. However, the molecular mechanisms underlying the control of longevity are still largely unknown. Here, we describe a T-DNA-insertional mutation of Arabidopsis thaliana that confers extended leaf longevity. The mutation, termed ore4-1 , delays a broad spectrum of age-dependent leaf senescence, but has little effect on leaf senescence artificially induced by darkness, abscisic acid (ABA), methyl jasmonate (MeJA), or ethylene. The T-DNA was inserted within the promoter region of the plastid ribosomal small subunit protein 17 (PRPS17 ) gene, and this insertion dramatically reduced PRPS17 mRNA expression. In the ore4-1 mutant, the leaf growth rate is decreased, while the maturation timing is similar to that of wild-type. In addition, the activity of the photosystem I (PSI) is significantly reduced in the ore4-1 mutant, as compared to wild-type. Thus, the ore4-1 mutation results in a deficiency in various chloroplast functions, including photosynthesis, which may decrease leaf growth. Our results suggest a possible link between reduced metabolism and extended longevity of the leaf organs in the ore4-1 mutation. | - |
