Project description:The rationale: Activation of the immune response antagonizes plant growth and development in absence of pathogen, and such autoimmune phenotype is often suppressed by the elevation of ambient temperature. However, the molecular regulation of ambient temperature-sensitive intersection of immune response and growth is largely elusive. Methods: A genetic screen identified an Arabidopsis mutant, zed1-D, by its high temperature-dependent growth retardation. A combination of molecular, cytological and genetic approaches was used to investigate the molecular basis behind the temperature-sensitive growth and immune response in zed1-D. Key results: A dominant mutation in HOPZ-ETI-DEFICIENT 1 (ZED1) is responsible for a high temperature-dependent autoimmunity and growth retardation in the zed1-D. The autoimmune phenotype in the zed1-D is dependent on the HOPZ-ACTIVATED RESISTANCE 1 (ZAR1). ZED1 and some ZED1-related kinases (ZRKs) are induced by elevated temperature and function cooperatively to suppress the immune response by modulating the transcription of SUPPRESSOR OF NPR1-1 CONSTITUTIVE 1 (SNC1) in absence of pathogen. Main conclusion: Our data reveal a previously unidentified role of ZRKs in ambient temperature-sensitive immune response in absence of pathogen, and thus disclose a possible molecular mechanism underlying temperature-mediated intersection of immune response and growth in plants.

Abstract:
Circadian clocks exhibit 'temperature compensation', meaning
that they show only small changes in period over a broad
temperature range. Several clock genes have been implicated in
the temperature-dependent control of period in Arabidopsis. We
show that blue light is essential for this, suggesting that the
effects of light and temperature interact or converge upon
common targets in the circadian clock. Our data demonstrate
that two cryptochrome photoreceptors differentially control
circadian period and sustain rhythmicity across the
physiological temperature range. In order to test the
hypothesis that the targets of light regulation are sufficient
to mediate temperature compensation, we constructed a
temperature-compensated clock model by adding passive
temperature effects into only the light-sensitive processes in
the model. Remarkably, this model was not only capable of full
temperature compensation and consistent with mRNA profiles
across a temperature range, but also predicted the
temperature-dependent change in the level of LATE ELONGATED
HYPOCOTYL, a key clock protein. Our analysis provides a
systems-level understanding of period control in the plant
circadian oscillator.

Project description:Pattern-recognition receptors (PRRs) mediate basal resistance to most phytopathogens. However, plant responses can be cell type-specific and the mechanisms governing xylem immunity remain largely unknown. We show that the lectin receptor-like kinase LORE contributes to xylem basal resistance in Arabidopsis upon infection with Ralstonia solanacearum, a destructive plant pathogen that colonizes the xylem to cause bacterial wilt. Following R. solanacearum infection, LORE is activated by phosphorylation at residue S761, initiating a phosphorelay that activates reactive oxygen species production and cell wall lignification. To prevent prolonged activation of immune signaling, LORE recruits and phosphorylates type 2C protein phosphatase LOPP, which dephosphorylates LORE and attenuates LORE-mediated xylem immunity to maintain immune homeostasis. A LOPP knockout confers resistance against bacterial wilt disease in Arabidopsis and tomatoes without impacting plant growth. Thus, our study reveals a regulatory mechanism in xylem immunity involving the reversible phosphorylation of receptor-like kinases

Project description:Arabidopsis MPK11 is activated and plays a role in the flg22 sensing. Mitogen-activated protein kinases (MAPKs) mediate cellular signal transduction during stress responses, as well as diverse growth and developmental steps in eukaryotes. Pathogen infection or treatment with conserved pathogen-associated molecular patterns (PAMPs) such as the bacterial flagellin-derived flg22 peptide are known to activate three Arabidopsis thaliana MAPKs, MPK3, MPK4 and MPK6. Several stresses, including flg22 treatment, are known to increase MPK11 expression but activation of MPK11 has not been shown. Here, we show that MPK11 activity can indeed be increased through flg22 elicitation. Expression profiling using a small-scale microarray for defense-related genes revealed that cinnamyl alcohol dehyrogenase 5 (CAD5) requires MPK11 for full flg22-induced expression. An mpk11 mutant showed increased flg22-mediated growth inhibition but no altered susceptibility to Pseudomonas syringae, Botrytis cinerea or Alternaria brassicicola. A 24 DNA microarray study using toral RNA from an Arabidopsis mutant (mpk11 SALK049352) as well as wild type treated with water or flg22.

Project description:We performed global scale microarray analysis to identify detailed mechanisms by which nonpermissive temperature induces cell growth arrest and differentiation in astrocyte RCG-12 cells harboring temperature-sensitive simian virus 40 large T-antigen by using an Affymetrix GeneChip system. Astrocyte RCG-12 cells used in this study were derived from primary cultured rat cortical glia cells infecting with a temperature-sensitive simian virus 40 large T-antigen. Although the cells grew continuously at the permissive temperature, the nonpermissive temperature led to cell growth arrest and differentiation. Of the 15,923 probe sets analyzed, nonpermissive temperature differentially expressed 556 probe sets by >2.0-fold. Keywords: Astrocyte cell; growth arrest; differentiation; temperature-sensitive simian virus 40 large T-antigen; nonpermissive temperature

Project description:The model plant Arabidopsis thaliana responds to mild high temperature by increased elongation growth of organs to enhance cooling capacity, in a process called thermomorphogenesis. Our understanding of the genetic regulation of thermomorphogenesis has increased in recent years. However, hardly anything is known about molecular mechanisms outside A. thaliana and cellular signaling pathways have been underexplored. Therefore, we mapped changes in protein phosphorylation in A. thaliana and crops exposed to warm temperature. Based on these results, we identified and characterized a novel, functionally conserved signaling complex of MITOGEN-ACTIVATED PROTEIN KINASE KINASE KINASE KINASEs (MAP4KS) in warm temperature-mediated growth regulation in plants. This contributes to our understanding of warm temperature signaling, and can help guarantee food security under a changing climate.
