      Arabidopsis Class I KNOTTED-Like Homeobox Proteins Act Downstream in the IDA-HAE/HSL2 Floral Abscission Signaling Pathway
      Chun-Lin Shi, Grethe-Elisabeth Stenvik, Ane Kjersti Vie, Atle M. Bones, Véronique Pautot, Marcel Proveniers, Reidunn B. Aalen, Melinka A. Butenko
      Plant Cell Jul 2011, 23 (7) 2553-2567; DOI: https://doi.org/10.1105/tpc.111.084608

      This work reports the characterization of a new mutant allele of the KNOX gene BP/KNAT1 and reveals that BP/KNAT1 inhibits floral organ abscission in Arabidopsis by restricting abscission zone cell size and number. It puts forward a model whereby IDA signaling suppresses BP/KNAT1, which in turn allows KNAT2 and KNAT6 to induce floral organ abscission.

      Plant Cell Jul 2011, 23 (7) 2708-2724; DOI: https://doi.org/10.1105/tpc.110.081547

      This study examines the lignin biosynthesis pathway in the lycophyte Selaginella moellendorffii. An O-methyltransferase gene was found clustered with the gene encoding a phenylpropanoid meta-hydroxylase known to catalyze the formation of syringyl lignin subunits. The O-methyltransferase is shown to function in the same enzymatic pathway as the phenylpropanoid meta-hydroxylase.

      A Novel Calcium Binding Site in the Slow Vacuolar Cation Channel TPC1 Senses Luminal Calcium Levels
      Beata Dadacz-Narloch, Diana Beyhl, Christina Larisch, Enrique J. López-Sanjurjo, Ralf Reski, Kazuyuki Kuchitsu, Thomas D. Müller, Dirk Becker, Gerald Schönknecht, Rainer Hedrich
      Plant Cell Jul 2011, 23 (7) 2696-2707; DOI: https://doi.org/10.1105/tpc.111.086751

      The slow vacuolar channel is the dominant cation channel of the vacuolar membrane and is regulated by cytosolic as well as vacuolar calcium. Here, the vacuolar calcium binding site is characterized at the molecular level, adding to our understanding of calcium signaling in the extracytosolic space.

      Perturbation of Arabidopsis Amino Acid Metabolism Causes Incompatibility with the Adapted Biotrophic Pathogen Hyaloperonospora arabidopsidis
      Johannes Stuttmann, Hans-Michael Hubberten, Steffen Rietz, Jagreet Kaur, Paul Muskett, Raphael Guerois, Paweł Bednarek, Rainer Hoefgen, Jane E. Parker
      Plant Cell Jul 2011, 23 (7) 2788-2803; DOI: https://doi.org/10.1105/tpc.111.087684

      This work identified two different Arabidopsis mutants that have reduced susceptibility to an infectious biotrophic pathogen due to overaccumulation of the amino acid Thr. This is detrimental for the host plant and the infecting pathogen but does not affect disease caused by some other pathogen species. Therefore, the host metabolic state can influence disease in quite a specific manner.

      Differential Regulation of Cellulose Orientation at the Inner and Outer Face of Epidermal Cells in the Arabidopsis Hypocotyl
      Elizabeth Faris Crowell, Hélène Timpano, Thierry Desprez, Tiny Franssen-Verheijen, Anne-Mie Emons, Herman Höfte, Samantha Vernhettes
      Plant Cell Jul 2011, 23 (7) 2592-2605; DOI: https://doi.org/10.1105/tpc.111.087338

      Whereas microtubules and cellulose synthase trajectories are transversely oriented on the outer epidermal surface of Arabidopsis hypocotyl cells only for part of the growth cycle, microtubules and microfibrils at the inner surface remain transverse throughout growth. The inner face of the epidermis is thus established as a regulator of growth anisotropy in the hypocotyl.

      Plant Cell Jul 2011, 23 (7) 2738-2753; DOI: https://doi.org/10.1105/tpc.111.086975

      Ectopic expression of a MYB transcription factor, ODO1, in tomato fruit altered Phe and phenylpropanoid metabolism, as shown by metabolic profiling and flux analysis. This disruption permitted identification of a set of coregulated genes, including prephenate aminotransferase, which converts prephenate to arogenate. The results establish a fruit arogenate pathway for Phe synthesis.

      Plant Cell Jul 2011, 23 (7) 2592-2605; DOI: https://doi.org/10.1105/tpc.111.087338

      Whereas microtubules and cellulose synthase trajectories are transversely oriented on the outer epidermal surface of Arabidopsis hypocotyl cells only for part of the growth cycle, microtubules and microfibrils at the inner surface remain transverse throughout growth. The inner face of the epidermis is thus established as a regulator of growth anisotropy in the hypocotyl.

      Ectopic expression of a MYB transcription factor, ODO1, in tomato fruit altered Phe and phenylpropanoid metabolism, as shown by metabolic profiling and flux analysis. This disruption permitted identification of a set of coregulated genes, including prephenate aminotransferase, which converts prephenate to arogenate. The results establish a fruit arogenate pathway for Phe synthesis.

      This work presents the cucumber mitochondrial genome sequence. Its extremely large size reflects the proliferation of dispersed repeats, large introns, and an abundance of chloroplast and nuclear DNA. The genome has an unusual multichromosomal structure, and computational analyses reveal a large number of recombinationally active repeats.

      This study shows that the major ubiquitin receptors involved in targeting ubiquitylated proteins for proteasome-mediated proteolysis are functionally redundant in Arabidopsis. Interestingly, in addition to playing a redundant role in substrate recognition, the Arabidopsis proteasome subunit RPN10 maintains the structural integrity of proteasome, which is critical for vegetative and reproductive growth.

      The plastid ribosomal release factor-like protein PrfB3 arose from a gene duplication and has subsequently lost the two most important tripeptide motifs required for stop codon recognition and catalysis. This work shows that PrfB3 is essential in vascular plants and has been recruited for binding and environment-dependent stabilization of petB RNA to regulate cytochrome b6f complex levels.

      This work identified two different Arabidopsis mutants that have reduced susceptibility to an infectious biotrophic pathogen due to overaccumulation of the amino acid Thr. This is detrimental for the host plant and the infecting pathogen but does not affect disease caused by some other pathogen species. Therefore, the host metabolic state can influence disease in quite a specific manner.

      This work identified two different Arabidopsis mutants that have reduced susceptibility to an infectious biotrophic pathogen due to overaccumulation of the amino acid Thr. This is detrimental for the host plant and the infecting pathogen but does not affect disease caused by some other pathogen species. Therefore, the host metabolic state can influence disease in quite a specific manner.

This disruption permitted identification of a set of coregulated genes, including prephenate aminotransferase, which converts prephenate to arogenate. The results establish a fruit arogenate pathway for Phe synthesis.

      Plant Cell Jul 2011, 23 (7) 2738-2753; DOI: https://doi.org/10.1105/tpc.111.086975

      Ectopic expression of a MYB transcription factor, ODO1, in tomato fruit altered Phe and phenylpropanoid metabolism, as shown by metabolic profiling and flux analysis. This disruption permitted identification of a set of coregulated genes, including prephenate aminotransferase, which converts prephenate to arogenate. The results establish a fruit arogenate pathway for Phe synthesis.

      Plant Cell Jul 2011, 23 (7) 2680-2695; DOI: https://doi.org/10.1105/tpc.111.085324

      The plastid ribosomal release factor-like protein PrfB3 arose from a gene duplication and has subsequently lost the two most important tripeptide motifs required for stop codon recognition and catalysis. This work shows that PrfB3 is essential in vascular plants and has been recruited for binding and environment-dependent stabilization of petB RNA to regulate cytochrome b6f complex levels.

      We constructed a CRE/lox clonal deletion system named BOB (Brother of Brainbow), which allows tissue-specific elimination of gametophytic essential genes from desired cells. The null sectors, marked by a combination of fluorescent proteins, show that genomic removal of RBR leads to cell-autonomous overproliferation of the quiescent center and distal columella stem cells.

      This work identified two different Arabidopsis mutants that have reduced susceptibility to an infectious biotrophic pathogen due to overaccumulation of the amino acid Thr. This is detrimental for the host plant and the infecting pathogen but does not affect disease caused by some other pathogen species. Therefore, the host metabolic state can influence disease in quite a specific manner.

      This study shows that the major ubiquitin receptors involved in targeting ubiquitylated proteins for proteasome-mediated proteolysis are functionally redundant in Arabidopsis. Interestingly, in addition to playing a redundant role in substrate recognition, the Arabidopsis proteasome subunit RPN10 maintains the structural integrity of proteasome, which is critical for vegetative and reproductive growth.

      Plant Cell Jul 2011, 23 (7) 2592-2605; DOI: https://doi.org/10.1105/tpc.111.087338

      Whereas microtubules and cellulose synthase trajectories are transversely oriented on the outer epidermal surface of Arabidopsis hypocotyl cells only for part of the growth cycle, microtubules and microfibrils at the inner surface remain transverse throughout growth. The inner face of the epidermis is thus established as a regulator of growth anisotropy in the hypocotyl.

      Plant Cell Jul 2011, 23 (7) 2553-2567; DOI: https://doi.org/10.1105/tpc.111.084608

      This work reports the characterization of a new mutant allele of the KNOX gene BP/KNAT1 and reveals that BP/KNAT1 inhibits floral organ abscission in Arabidopsis by restricting abscission zone cell size and number. It puts forward a model whereby IDA signaling suppresses BP/KNAT1, which in turn allows KNAT2 and KNAT6 to induce floral organ abscission.

      Plant Cell Jul 2011, 23 (7) 2581-2591; DOI: https://doi.org/10.1105/tpc.111.086199

      We constructed a CRE/lox clonal deletion system named BOB (Brother of Brainbow), which allows tissue-specific elimination of gametophytic essential genes from desired cells. The null sectors, marked by a combination of fluorescent proteins, show that genomic removal of RBR leads to cell-autonomous overproliferation of the quiescent center and distal columella stem cells.

      Plant Cell Jul 2011, 23 (7) 2708-2724; DOI: https://doi.org/10.1105/tpc.110.081547

      This study examines the lignin biosynthesis pathway in the lycophyte Selaginella moellendorffii. An O-methyltransferase gene was found clustered with the gene encoding a phenylpropanoid meta-hydroxylase known to catalyze the formation of syringyl lignin subunits. The O-methyltransferase is shown to function in the same enzymatic pathway as the phenylpropanoid meta-hydroxylase.

      Plant Cell Jul 2011, 23 (7) 2680-2695; DOI: https://doi.org/10.1105/tpc.111.085324

      The plastid ribosomal release factor-like protein PrfB3 arose from a gene duplication and has subsequently lost the two most important tripeptide motifs required for stop codon recognition and catalysis. This work shows that PrfB3 is essential in vascular plants and has been recruited for binding and environment-dependent stabilization of petB RNA to regulate cytochrome b6f complex levels.

      Plant Cell Jul 2011, 23 (7) 2568-2580; DOI: https://doi.org/10.1105/tpc.111.087643

      In plants grown under field conditions, seed dormancy varies considerably with the time of year the seed is set, and this variation is important for the coordination of plant life history and seed quality. This work elucidates the mechanisms through which environmental temperature during seed set affects the germination behavior of seeds when released from the mother plant.

      In the cyanobacterial photoprotective mechanism, one red-activated Orange Carotenoid Protein binds to the core of the phycobilisome and quenches all its fluorescence. This binding stabilizes the red form. Addition of the Fluorescence Recovery Protein accelerates fluorescence recovery in darkness by interacting with the red protein and destabilizing its binding to the phycobilisome.
