      The Arabidopsis Leucine-Rich Repeat Receptor–Like Kinases BAK1/SERK3 and BKK1/SERK4 Are Required for Innate Immunity to Hemibiotrophic and Biotrophic Pathogens
      Milena Roux, Benjamin Schwessinger, Catherine Albrecht, Delphine Chinchilla, Alexandra Jones, Nick Holton, Frederikke Gro Malinovsky, Mahmut Tör, Sacco de Vries, Cyril Zipfel
      Plant Cell Jun 2011, 23 (6) 2440-2455; DOI: https://doi.org/10.1105/tpc.111.084301

      This work demonstrates that the leucine-rich receptor kinases (LRR-RKs) EFR and FLS2 form a ligand-induced complex with several LRR-RKs that belong to the SERK subfamily. Among these, BAK1 and BKK1 play an important role in responses to EF-Tu, flagellin, and other elicitors of plant defense and are required for full immunity to hemibiotrophic and biotrophic pathogens.

      Maize opaque5 Encodes Monogalactosyldiacylglycerol Synthase and Specifically Affects Galactolipids Necessary for Amyloplast and Chloroplast Function
      Alan M. Myers, Martha G. James, Qiaohui Lin, Gibum Yi, Philip S. Stinard, Tracie A. Hennen-Bierwagen, Philip W. Becraft
      Plant Cell Jun 2011, 23 (6) 2331-2347; DOI: https://doi.org/10.1105/tpc.111.087205

      The maize gene opaque5 encodes a monogalactosyldiacylglycerol synthase. Mutant analysis reveals that galactolipids with five double bonds are needed for thylakoid membrane function and cannot be substituted by the prevalent species with six double bonds. Galactolipid reduction results in altered starch granules, indicating a connection between amyloplast membranes and starch biosynthesis.

      Plant Cell Jun 2011, 23 (6) 2087-2105; DOI: https://doi.org/10.1105/tpc.111.086264

      We carried out a comparative transcriptome analysis in leaves of five closely related C3, C4, and C3-C4 intermediate Flaveria species to gain insight into the extent to which gene expression patterns were altered in the evolutionary progression from C3 to C4. The comparative analysis indicates that C4 evolution affected far more biological functions than only photosynthesis.

      Malonyl-CoA Synthetase, Encoded by ACYL ACTIVATING ENZYME13, Is Essential for Growth and Development of Arabidopsis
      Hui Chen, Hyun Uk Kim, Hua Weng, John Browse
      Plant Cell Jun 2011, 23 (6) 2247-2262; DOI: https://doi.org/10.1105/tpc.111.086140

      Malonic acid inhibits succinate dehydrogenase and is toxic to Arabidopsis seedlings. Biochemical assays demonstrate that ACYL ACTIVATING ENZYME13 (AAE13) of Arabidopsis is a malonyl-CoA synthetase. Characterization of an aae13 mutant indicates that the malonyl-CoA synthetase encoded by AAE13 is required for detoxification of endogenous malonate and for healthy growth and development of plants.

      This work demonstrates that the leucine-rich receptor kinases (LRR-RKs) EFR and FLS2 form a ligand-induced complex with several LRR-RKs that belong to the SERK subfamily. Among these, BAK1 and BKK1 play an important role in responses to EF-Tu, flagellin, and other elicitors of plant defense and are required for full immunity to hemibiotrophic and biotrophic pathogens.

      Functional analyses of cytokinin (CK)-deficient plants provide direct evidence that CKs negatively regulate plant response to drought and salt stresses. CK-deficient plants exhibited a strong stress-tolerant phenotype associated with abscisic acid (ABA) hypersensitivity. This study suggests that mutual regulation mechanisms between CK and ABA affect the plant’s adaptation to stressors and plant growth and development.

      Rice pps is a heterochronic mutant that shows a prolonged juvenile phase by repressing GA biosynthetic genes and altering expression patterns of microRNA genes but is early flowering. Positional cloning revealed that PPS is the ortholog of Arabidopsis COP1. Although PPS has a role in photomorphogenesis as COP1 does, PPS has additional roles in vegetative phase change and flowering time regulation.

      Plant Cell Jun 2011, 23 (6) 2331-2347; DOI: https://doi.org/10.1105/tpc.111.087205

      The maize gene opaque5 encodes a monogalactosyldiacylglycerol synthase. Mutant analysis reveals that galactolipids with five double bonds are needed for thylakoid membrane function and cannot be substituted by the prevalent species with six double bonds. Galactolipid reduction results in altered starch granules, indicating a connection between amyloplast membranes and starch biosynthesis.

      Plant Cell Jun 2011, 23 (6) 2106-2124; DOI: https://doi.org/10.1105/tpc.111.085464

      This work shows that a mutation of the PIN1 ortholog in Medicago truncatula, SLM1, caused multiple terminal leaflets and a reduction of lateral leaflets. Characterization of the mutant reveals that the terminal leaflet primordium in M. truncatula has a unique developmental mechanism and the elaboration of compound leaves is context dependent and tightly correlated with the auxin/SLM1 module.

      This work demonstrates that the leucine-rich receptor kinases (LRR-RKs) EFR and FLS2 form a ligand-induced complex with several LRR-RKs that belong to the SERK subfamily. Among these, BAK1 and BKK1 play an important role in responses to EF-Tu, flagellin, and other elicitors of plant defense and are required for full immunity to hemibiotrophic and biotrophic pathogens.

      Gibberellin Regulates PIN-FORMED Abundance and Is Required for Auxin Transport–Dependent Growth and Development in Arabidopsis thaliana
      Björn C. Willige, Erika Isono, René Richter, Melina Zourelidou, Claus Schwechheimer
      Plant Cell Jun 2011, 23 (6) 2184-2195; DOI: https://doi.org/10.1105/tpc.111.086355

      This work presents physiological, cell biological, and developmental data that establish that gibberellins (GA) is required for proper polar auxin transport in Arabidopsis thaliana. It shows that the GA pathway interacts with PIN protein-dependent auxin transport and development, suggesting that at least some of the growth defects of GA biosynthesis and signaling mutants are a result of altered auxin transport.
