Production Cell

Acidovorax citrulli (Ac) is the causative agent of bacterial fruit blotch disease in watermelon. Since resistant cultivars have not yet been developed, the virulence factors/mechanisms of Ac need to be characterized. This study reports the functions of a putative pyridoxal phosphate-dependent aminotransferase (PpdaAc) that transfers amino groups to its substrates and uses pyridoxal phosphate as a coenzyme. It was observed that a ppdaAc knockout mutant had a significantly reduced virulence in watermelon when introduced via germinated-seed inoculation as well as leaf infiltration. Comparative proteomic analysis predicted the cellular mechanisms related to PpdaAc. Apart from causing virulence, the PpdaAc may have significant roles in energy production, cell membrane, motility, chemotaxis, post-translational modifications, and iron-related mechanisms. Therefore, it is postulated that PpdaAc may possess pleiotropic effects. These results provide new insights into the functions of a previously unidentified PpdaAc in Ac.

Seed Germination Proteins

Abstract During seed germination, proteins are translated not only from mRNAs newly transcribed upon imbibition but also from long-lived mRNAs that are synthesized during seed maturation and stored in the mature dry seeds. To clarify the distinct roles of proteins translated from long-lived mRNAs and de novo transcribed mRNAs in germinating rice embryos, proteome analysis based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) combining the use of a transcriptional inhibitor was performed. We observed that α-amanitin significantly represses transcription in germinating embryos; nevertheless, the embryos could germinate, albeit slowly. The proteomic analysis revealed that a total of 109 proteins were translated from long-lived mRNAs associated with germination as well as 222 proteins whose expression were dependent on de novo transcription upon imbibition. Transcriptomic datasets available in public databases demonstrated that mRNAs of the 222 proteins notably increased during germination while those of the 109 proteins highly accumulated in dry embryos and constitutively expressed upon imbibition. Gene Ontology enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis indicated that many of the 109 proteins from long-lived mRNAs are implicated in energy production such as glycolysis or annotated as nucleotide binding proteins, while the 222 proteins are involved in pathways such as pyruvate metabolism and TCA cycle following glycolysis, and momilactones biosynthesis. We propose that long-lived mRNAs support initial energy production and activation of translational machinery upon imbibition whereas de novo transcription accelerates the energy production after glycolysis, which enables rice seeds to germinate vigorously.

In the past most studies of the control of energy metabolism focus on the role of the phosphorylation potential ATP/ADP.Pi on the regulation of respiration. Studies using NMR techniques have demonstrated that the concentrations of these compounds for oxidation phosphorylation do not change appreciably throughout the cardiac cycle and during increases in cardiac work. Hence regulation of energy production by calcium ions, present in the mitochondrial matrix, has been the object of a number of recent studies.Three exclusively intramitochondnal dehydrogenases are key enzymes for the regulation of oxidative metabolism. They are activated by calcium ions in the low micromolar range. Since, however, earlier estimates of the intramitochondnal calcium, based on equilibrium thermodynamic considerations, were in the millimolar range, a physiological correlation was not evident. The introduction of calcium-sensitive probes fura-2 and indo-1 made monitoring of free calcium during changing energy metabolism possible. These studies were performed on isolated mitochondria and extrapolation to the in vivo situation is more or less speculative.
