- Open AccessProteomic Identification and Characterization of a Novel Peroxisomal Adenine Nucleotide Transporter Supplying ATP for Fatty Acid β-Oxidation in Soybean and ArabidopsisYuko Arai, Makoto Hayashi, Mikio NishimuraPlant Cell Dec 2008, 20 (12) 3227-3240; DOI: https://doi.org/10.1105/tpc.108.062877
This work identifies a novel protein, Glycine max PEROXISOMAL ADENINE NUCLEOTIDE CARRIER (PNC1), by proteomic analyses of peroxisomal membrane proteins. PNC1 and its homologs in Arabidopsis contribute to the transport of adenine nucleotides that are consumed by reactions to generate acyl-CoA for peroxisomal fatty acid β-oxidation during postgerminative growth.

- Open AccessFunctional Proteomics of Arabidopsis thaliana Guard Cells Uncovers New Stomatal Signaling PathwaysZhixin Zhao, Wei Zhang, Bruce A. Stanley, Sarah M. AssmannPlant Cell Dec 2008, 20 (12) 3210-3226; DOI: https://doi.org/10.1105/tpc.108.063263
This study identifies 1734 proteins of the guard cell proteome, examines novel signaling pathways, and finds that a myrosinase implicated in plant–herbivore interactions, THIOGLUCOSIDE GLUCOHYDROLASE1 (TGG1), is abundant in guard cells. Mutant analysis reveals key roles of TGG1 in ABA regulation of K+ channels and stomatal apertures, suggesting interplay between biotic and abiotic signaling.

The Arabidopsis translationally controlled tumor protein (TCTP) regulates vegetative growth, lateral root formation, and root hair development,and is also critical to pollen tube growth. These effects suggest that TCTP acts in the plant TOR signalling network, as in humans and Drosophila, but with plant-specific features such as crosstalk with auxin signaling.

The authors show that Arabidopsis PDIL2-1 is a functional protein disulfide isomerase localized in the ER and highly expressed in the micropylar region of the ovule. They also show that gain-of-function mutations, caused by truncated versions of enzymatically active PDIL2-1, act in sporophytic tissues. These mutations delay embryo sac maturation and disrupt pollen tube guidance in Arabidopsis.

The organization of microtubule arrays in plant cell morphogenesis depends on proteins that bundle microtubules. The major bundling protein is MAP65, which is encoded by a gene family comprising different isotypes that have unique abilities important for cell cycle progression. This work shows that a specific region in the C terminus of each isotype is essential for its unique function.

Expression of ASL19 and ASL20 in immature xylem vessels depends on VND6 and VND7, two key positive regulators of xylem differentiation. ASL19/20 overexpression generates xylem-like cells and induces ectopic VND7 expression in nonvascular tissues. Thus, ASL19 and ASL20 seem to be involved in a positive feedback loop for VND6/7 expression that regulates xylem differentiation.

REPRESSION OF SHOOT GROWTH (RSG) is a transcriptional activator functioning in GA feedback by regulating GA biosynthetic enzymes. This work identified a Ca2+-dependent protein kinase that regulates RSG by phosphorylation of RSG residue Ser-114. These results suggest that CDPK decodes the Ca2+ signal produced by GAs and regulates the intracellular localization of RSG.

Plants surviving under subzero temperatures in winter enhance their freezing tolerance during the fall season to avoid irreversible damage to the plasma membrane. This work provides evidence that the plant synaptotagmin SYT1 functions to enhance freezing tolerance by facilitating the membrane resealing that is essential for cells to survive after the plasma membrane is damaged.

This work provides evidence that the plant synaptotagmin SYT1 functions to enhance freezing tolerance by facilitating the membrane resealing that is essential for cells to survive after the plasma membrane is damaged.

- Open AccessStarch Granule Biosynthesis in Arabidopsis Is Abolished by Removal of All Debranching Enzymes but Restored by the Subsequent Removal of an EndoamylaseSebastian Streb, Thierry Delatte, Martin Umhang, Simona Eicke, Martine Schorderet, Didier Reinhardt, Samuel C. ZeemanPlant Cell Dec 2008, 20 (12) 3448-3466; DOI: https://doi.org/10.1105/tpc.108.063487
The major component of starch granules, amylopectin, is a branched glucan, the structure of which is determined by starch synthases, branching enzymes and debranching enzymes. This study reveals that when debranching enzymes are missing, amylases not normally involved in biosynthesis act on the nascent glucans, modifying their structure and thereby preventing starch granule formation.

The Rfo locus restores fertility to radish plants with Ogura cytoplasmic male sterility. Using transgenic rapeseed plants expressing genes of this locus, this study shows that the product of one gene associates in vivo with the sterility gene RNA and restores fertility by suppressing the synthesis of the sterility protein in the tapetum of anthers.

The authors show that Arabidopsis PDIL2-1 is a functional protein disulfide isomerase localized in the ER and highly expressed in the micropylar region of the ovule. They also show that gain-of-function mutations, caused by truncated versions of enzymatically active PDIL2-1, act in sporophytic tissues. These mutations delay embryo sac maturation and disrupt pollen tube guidance in Arabidopsis.

REPRESSION OF SHOOT GROWTH (RSG) is a transcriptional activator functioning in GA feedback by regulating GA biosynthetic enzymes. This work identified a Ca2+-dependent protein kinase that regulates RSG by phosphorylation of RSG residue Ser-114. These results suggest that CDPK decodes the Ca2+ signal produced by GAs and regulates the intracellular localization of RSG.
