- Open AccessCatalase and NO CATALASE ACTIVITY1 Promote Autophagy-Dependent Cell Death in ArabidopsisThomas Hackenberg, Trine Juul, Aija Auzina, Sonia Gwiżdż, Anna Małolepszy, Katrien Van Der Kelen, Svend Dam, Simon Bressendorff, Andrea Lorentzen, Peter Roepstorff, Kåre Lehmann Nielsen, Jan-Elo Jørgensen, Daniel Hofius, Frank Van Breusegem, Morten Petersen, Stig Uggerhøj AndersenPlant Cell Nov 2013, 25 (11) 4616-4626; DOI: https://doi.org/10.1105/tpc.113.117192
Catalase directly interacts with and detoxifies reactive oxygen species. This work identifies catalase-deficient mutants in a screen for suppression of cell death and finds that promotion of cell death associated with the plant hypersensitive response requires catalase, suggesting that catalase could act as a direct molecular link between reactive oxygen species and cell death signaling.

This work shows that HOS1, previously characterized as a nuclear pore–associated E3 ubiquitin ligase, is required for nucleo-cytoplasmic mRNA export. This study demonstrates that this reduction in nucleo-cytoplasmic export by hos1, or mutations to other previously characterized nuclear pore–associated proteins, leads to altered RNA levels and rhythms, circadian clock function, and cold signaling.

Aldoximes are precursors of several classes of direct plant defense compounds. This study characterizes two cytochrome P450 monooxygenase enzymes, CYP79D6/7, which are involved in gypsy moth–induced aldoxime formation in western balsam poplar. Volatile formation mediated by CYP79s may be a general phenomenon in the plant kingdom.

This article identifies and characterizes an Arabidopsis protein, GGCT2;1, which has a cation transport regulator-like (ChaC-like) domain that functions as a γ-glutamyl cyclotransferase. In vivo studies in yeast and Arabidopsis establish that GGCT2;1 recycles Glu as part of the γ-glutamyl cycle and thus maintains GSH homeostasis to counteract heavy metal and metalloids toxicity.

The expression of calmodulin isoforms with unique Ca2+ binding affinities could confer on plant cells an additional ability to translate the distinct Ca2+ signals that accompany various stimuli. Using isoforms of conserved and divergent calmodulin sequences, this study finds that differences in affinity and the effect of competing Mg2+ tunes the responsiveness of the isoforms to the appropriate Ca2+ signature.

Some stages of the protein N-glycosylation pathway are required for corn smut (Ustilago maydis) to successfully infect its host plant. If fungal proteins are not properly glycosylated, the host plant can detect the infection and activate defense mechanisms to suppress it. Disruption of glycosylation pathways in Ustilago reduces its infectious capabilities but has few other phenotypes.

This work characterizes two cytochrome P450s and two monoterpene synthases that are coexpressed in flowers and thus predicted to be involved in monoterpenoid metabolism. The results show that despite Arabidopsis thaliana being autogamous, its flowers exhibit extensive linalool metabolism.

This work characterizes transgenic lines with altered expression of calmodulin (CaM) N-methyltransferase to demonstrate that the methylation status of CaM plays a role in CaM-mediated signaling pathways. The findings add a new level of complexity to our understanding of CaM signaling mechanisms in plants.

This work identifies the Arabidopsis thaliana mutant maigo5 (mag5), which abnormally accumulates precursor forms of storage proteins. MAG5 is a plant ortholog of yeast Sec16 that is a key component for COPII vesicle formation. MAG5/SEC16A is required for protein export from the ER and functions at ERESs that are associated with mobile Golgi stacks where it regulates COPII coat turnover.

Pathway engineering has been the predominant strategy used to enhance valuable natural products in plants. This study identifies sequestration mechanisms associated with pathway engineering outputs that enable the plastid organelle to adapt and accommodate newly synthesized precursors and products.

Kinesin-13A is a microtubule depolymerizing protein and is required for formation of secondary wall pit in metaxylem vessels. Kinesin-13A promotes local disassembly of cortical microtubules through Rho of Plant GTPase-MIDD1 complex to develop secondary wall pits. This study demonstrates that a pathway regulates cell wall structure through local regulation of cortical microtubule dynamics.

This work shows that HOS1, previously characterized as a nuclear pore–associated E3 ubiquitin ligase, is required for nucleo-cytoplasmic mRNA export. This study demonstrates that this reduction in nucleo-cytoplasmic export by hos1, or mutations to other previously characterized nuclear pore–associated proteins, leads to altered RNA levels and rhythms, circadian clock function, and cold signaling.

Plastid-localized glutathione reductase2 regulates root growth and root meristem maintenance through modulation of its GSH redox status, resulting in regulation of downstream effectors of the auxin/PLETHORA pathway, as well as of some auxin/ PLETHORA-independent pathways. This function differs from that of glutathione reductase1, which is not essential for plant development.

This study demonstrates that salt stress–induced changes in actin microfilament dynamics regulate mitochondrial movement and activity, which in turn regulate a salt-induced calcium change and cell death.
