      Catalase and NO CATALASE ACTIVITY1 Promote Autophagy-Dependent Cell Death in Arabidopsis
      Thomas 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 Andersen
      Plant 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.

      Ser palmitoyltransfersase (SPT) regulation of sphingolipid homeostasis is critical for mediating plant growth and programmed cell death (PCD). As key components of this regulation, two 56–amino acid SPT-interacting proteins are shown to be essential for male gametophyte viability, and altered expression strongly affects SPT activity and sensitivity to the PCD-inducing mycotoxin fumonisin B1.

      Ser palmitoyltransfersase (SPT) regulation of sphingolipid homeostasis is critical for mediating plant growth and programmed cell death (PCD). As key components of this regulation, two 56–amino acid SPT-interacting proteins are shown to be essential for male gametophyte viability, and altered expression strongly affects SPT activity and sensitivity to the PCD-inducing mycotoxin fumonisin B1.

      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.

      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.

      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.

      Ser palmitoyltransfersase (SPT) regulation of sphingolipid homeostasis is critical for mediating plant growth and programmed cell death (PCD). As key components of this regulation, two 56–amino acid SPT-interacting proteins are shown to be essential for male gametophyte viability, and altered expression strongly affects SPT activity and sensitivity to the PCD-inducing mycotoxin fumonisin B1.

      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 study shows that cryptochrome2 (CRY2) mediates light suppression of leaf senescence in soybean by interacting with the bHLH transcription factor CIB1. In the absence of blue light or CRY2 signal, CIB1 binds to the E-box DNA motif of the promoter of senescence-associated genes to promote leaf senescence. In blue light, CRY2 interacts with CIB1 to inhibit its DNA binding and leaf senescence.
