25. Optimal Thermal Environments for Plant Metabolic Processes (Cucumis sativus L.) (Light-Harvesting Chlorophyll a/b Pigment-Protein Complex of Photosystem II and Seedling Establishment in Cucumber).
Analysis of the temperatures providing maximal photosystem II fluorescence reappearance following illumination and thermal kinetic windows (TKWs), obtained from the temperature characteristics of enzyme apparent Km values, have been proposed as indicators of the bounds of thermal stress in plants. In this study, we have evaluated the temperature optimum for

26. The Effect of α-Amanitin on the Arabidopsis Seed Proteome Highlights the Distinct Roles of Stored and Neosynthesized mRNAs during Germination1
To investigate the role of stored and neosynthesized mRNAs in seed germination, we examined the effect of α-amanitin, a transcriptional inhibitor targeting RNA polymerase II, on the germination of nondormant Arabidopsis seeds. We used transparent testa mutants, of which seed coat is highly permeable, to better ascertain that the drug can reach the embryo du

27. Arginine Catabolism in the Cyanobacterium Synechocystis sp. Strain PCC 6803 Involves the Urea Cycle and Arginase Pathway
Cells of the unicellular cyanobacterium Synechocystis sp. strain PCC 6803 supplemented with micromolar concentrations of l-[14C]arginine took up, concentrated, and catabolized this amino acid. Metabolism of l-[14C]arginine generated a set of labeled amino acids that included argininosuccinate, citrulline, glutamate, glutamine, ornithine, and proline. Product
