      Using a protoplast-based promoter-activation system, this work identifies a MYB-like factor termed EOBI that is important in floral scent production. Direct interactions of EOBI with EOBII and of both proteins with ODO1 and structural phenylpropanoid scent-related genes allow tight regulation of scent throughout flower development.

      Plant Cell Dec 2012, 24 (12) 4850-4874; DOI: https://doi.org/10.1105/tpc.112.107144

      This work examines the postembryonic functions of Target of Rapamycin (TOR) in Arabidopsis by generating rapamycin-sensitive Arabidopsis plants via transgenic expression of a yeast protein. Examination of these lines indicates that in plants, as in animals, TOR acts in the integration of metabolism, nutrition, and life span.

      April Jennifer Madrid Liwanag, Berit Ebert, Yves Verhertbruggen, Emilie A. Rennie, Carsten Rautengarten, Ai Oikawa, Mathias C.F. Andersen, Mads H. Clausen, Henrik Vibe Scheller
      Plant Cell Dec 2012, 24 (12) 5024-5036; DOI: https://doi.org/10.1105/tpc.112.106625

      GALS1, GALS2, and GALS3 are members of glycosyltransferase family GT92 in Arabidopsis thaliana. Loss-of-function mutants in the three corresponding genes are deficient in pectic β-1,4-galactan. GALS1 is shown to function as a β-1,4-galactan synthase in vitro, and GALS1 overexpressors have a 50% increased content of β-1,4-galactan in the cell walls.

      This article provides an analysis of chloroplast signal recognition particle (cpSRP) evolution within the green and red lineages. A focus lies on the distribution and characterization of the plastid-encoded SRP RNA component. Furthermore, the cpSRP system of Physcomitrella patens containing an SRP RNA and a cpSRP43 component was investigated, and the structure of the cpFtsY receptor was solved.

      Many plant microRNAs are deeply conserved in all land plants, from mosses to flowering plants. We carry out functional studies of two such microRNAs, miR156 and miR390, in the moss Physcomitrella patens and identify them as components of a broadly conserved gene regulatory network that controls the timing of plant development.

      Plant Cell Dec 2012, 24 (12) 4917-4929; DOI: https://doi.org/10.1105/tpc.112.105163

      This work reveals that two non-DNA binding HLH factors (PRE1 and IBH1) and a DNA binding bHLH factor (HBI1) form an interaction cascade that controls cell elongation. BR, GA, light, and temperature signals regulate the expression level of PRE1; PRE1 binds to and inhibits IBH1; IBH1 interacts with and inhibits HBI1 binding to promoter DNA of two EXPANSIN genes.

      Pipecolic Acid, an Endogenous Mediator of Defense Amplification and Priming, Is a Critical Regulator of Inducible Plant Immunity

      Plant Cell Dec 2012, 24 (12) 5123-5141; DOI: https://doi.org/10.1105/tpc.112.103564

      The Lys catabolite pipecolic acid (Pip) is identified as a critical signal for several forms of inducible plant immunity, acting as a central component of a feedback amplification mechanism that potentiates plant defense responses. Accumulation of Pip is necessary for the establishment of systemic acquired resistance (SAR) and sufficient to trigger SAR-related defense priming.

      This chemical genetics work reveals natural variation in a newly identified R protein homolog, named VICTR, that produces primary root growth arrest in response to the small molecule DFPM. DFPM perception and signal transduction require early components of the plant R gene resistance signaling network, and the R protein VICTR coresides in complexes not only with EDS1 but also PAD4.

      GALS1, GALS2, and GALS3 are members of glycosyltransferase family GT92 in Arabidopsis thaliana. Loss-of-function mutants in the three corresponding genes are deficient in pectic β-1,4-galactan. GALS1 is shown to function as a β-1,4-galactan synthase in vitro, and GALS1 overexpressors have a 50% increased content of β-1,4-galactan in the cell walls.

Sugars from photosynthesis, the hormone auxin, and members of the PHYTOCHROME INTERACTING FACTOR (PIF) family of proteins have all been shown individually to regulate growth. This work shows that sugars regulate auxin biosynthesis via PIF proteins, indicating that the three in fact act together in growth regulation.

Furthermore, the cpSRP system of Physcomitrella patens containing an SRP RNA and a cpSRP43 component was investigated, and the structure of the cpFtsY receptor was solved.

      This chemical genetics work reveals natural variation in a newly identified R protein homolog, named VICTR, that produces primary root growth arrest in response to the small molecule DFPM. DFPM perception and signal transduction require early components of the plant R gene resistance signaling network, and the R protein VICTR coresides in complexes not only with EDS1 but also PAD4.

      Using a protoplast-based promoter-activation system, this work identifies a MYB-like factor termed EOBI that is important in floral scent production. Direct interactions of EOBI with EOBII and of both proteins with ODO1 and structural phenylpropanoid scent-related genes allow tight regulation of scent throughout flower development.

Examination of these lines indicates that in plants, as in animals, TOR acts in the integration of metabolism, nutrition, and life span.

      Coordinated spatiotemporal-specific cell proliferation is critical to plant growth and development. This study demonstrates the function of a mitogen-activated protein kinase cascade downstream of the ERECTA receptor-like kinase in regulating localized cell proliferation, which determines the inflorescence architecture and size in Arabidopsis thaliana.

      Whether the leaflet shape gene Ln has a pleiotropic effect on the number of seeds per pod (NSPP) trait or not has long been debated in soybean research. This study shows that both the leaflet shape and NSPP traits are regulated by a single gene, which is a homolog of Arabidopsis JAGGED that regulates leaf and flower development, and establishes a novel role for JAGGED in fruit development.

      This article provides an analysis of chloroplast signal recognition particle (cpSRP) evolution within the green and red lineages. A focus lies on the distribution and characterization of the plastid-encoded SRP RNA component. Furthermore, the cpSRP system of Physcomitrella patens containing an SRP RNA and a cpSRP43 component was investigated, and the structure of the cpFtsY receptor was solved.

      The Lys catabolite pipecolic acid (Pip) is identified as a critical signal for several forms of inducible plant immunity, acting as a central component of a feedback amplification mechanism that potentiates plant defense responses. Accumulation of Pip is necessary for the establishment of systemic acquired resistance (SAR) and sufficient to trigger SAR-related defense priming.

      Plants adjust growth to suit opportunities and limitations in their environment. Sugars from photosynthesis, the hormone auxin, and members of the PHYTOCHROME INTERACTING FACTOR (PIF) family of proteins have all been shown individually to regulate growth. This work shows that sugars regulate auxin biosynthesis via PIF proteins, indicating that the three in fact act together in growth regulation.

      Plants adjust growth to suit opportunities and limitations in their environment. Sugars from photosynthesis, the hormone auxin, and members of the PHYTOCHROME INTERACTING FACTOR (PIF) family of proteins have all been shown individually to regulate growth. This work shows that sugars regulate auxin biosynthesis via PIF proteins, indicating that the three in fact act together in growth regulation.

      This study indentifies Arabidopsis UBP16 as a functional ubiquitin-specific protease involved in salt tolerance and SERINE HYDROXYMETHYLTRANSFERASE1 as a putative target of UBP16.

      This article provides an analysis of chloroplast signal recognition particle (cpSRP) evolution within the green and red lineages. A focus lies on the distribution and characterization of the plastid-encoded SRP RNA component. Furthermore, the cpSRP system of Physcomitrella patens containing an SRP RNA and a cpSRP43 component was investigated, and the structure of the cpFtsY receptor was solved.
