Compared with small heat shock proteins (sHSPs) in other organisms, those plants are the most abundant and diverse. However, molecular mechanisms by which sHSPs involved cell protection remain unknown. Here, we characterized role of HSP21, a plastid nucleoid-localized sHSP, chloroplast development under stress. We show that an Arabidopsis thaliana knockout mutant HSP21 had ivory phenotype Quantitative real-time RT-PCR, run-on transcription, RNA gel blot, polysome association analyses...
Abstract To gain insights into the molecular details of photosystem I (PSI) biogenesis, we characterized PsbP-domain protein1 (ppd1) mutant Arabidopsis thaliana that specifically lacks PSI activity. Deletion PPD1 results in an inability to grow photoautotrophically and a specific loss stable complex. Unaltered transcription translation plastid-encoded genes indicate acts at posttranslational level. In vivo protein labeling experiments reveal rate synthesis reaction center proteins PsaA/B...
Yield in cereals is a function of grain number and size. Sucrose (Suc), the main carbohydrate product photosynthesis higher plants, transported long distances from source leaves to sink organs such as seeds roots. Here, we report that transgenic rice plants (Oryza sativa) expressing Arabidopsis (Arabidopsis thaliana) phloem-specific Suc transporter (AtSUC2), which loads into phloem under control protein2 promoter (pPP2), showed an increase yield up 16% relative wild-type field trials....
Abstract Whole spinach (Spinacia oleracea) plants were subjected to heat stress (25°C–50°C) in the dark for 30 min. At temperatures higher than 35°C, CO2 assimilation rate decreased significantly. The maximal efficiency of photosystem II (PSII) photochemistry remained unchanged until 45°C and only slightly at 50°C. Nonphotochemical quenching increased significantly either absence or presence dithiothreitol. There was an appearance characteristic band around 698 nm 77 K fluorescence emission...
Significance Our results demonstrate that SUPPRESSOR OF THYLAKOID FORMATION 1 (SOT1), an Arabidopsis pentatricopeptide repeat (PPR) protein with a small MutS-related (SMR) domain, has endonuclease activity. The SMR moiety of SOT1 performs the endonucleolytic maturation 23S and 4.5S rRNA through PPR domain specifically recognizing 13-nucleotide RNA sequence in 5′ end chloroplast 23S–4.5S precursor. also show can be engineered to recognize cleave predicted substrate. findings suggest could...
Glutathione reductase (GR) catalyzes the reduction of glutathione disulfide (GSSG) to reduced (GSH) and participates in ascorbate-glutathione cycle, which scavenges H2 O2 . Here, we report that chloroplastic/mitochondrial GR2 is an important regulator leaf senescence. Seed development homozygous gr2 knockout mutant was blocked at globular stage. Therefore, investigate function senescence, generated transgenic Arabidopsis plants with decreased using RNAi. The RNAi displayed early onset...
