Chloroplasts modulate elongation responses to canopy shade by retrograde pathways involving HY5 and abscisic acid / Ortiz-Alcaide, Miriam (Centre de Recerca en Agrigenòmica) ; Llamas, Ernesto (Centre de Recerca en Agrigenòmica) ; Gómez-Cadenas, Aurelio (Universitat Jaume I) ; Nagatani, Akira (Kyoto University) ; Martínez-García, Jaime F. (Centre de Recerca en Agrigenòmica) ; Rodríguez Concepción, Manuel (Centre de Recerca en Agrigenòmica)
Plants use light as energy for photosynthesis but also as a signal of competing vegetation. Using different concentrations of norflurazon and lincomycin, we found that the response to canopy shade in Arabidopsis (Arabidopsis thaliana) was repressed even when inhibitors only caused a modest reduction in the level of photosynthetic pigments.

Institut de Ciències Fotòniques) ; Li Li (Robert W. Holley Center for Agriculture and Health) ; Rodríguez Concepción, Manuel (Centre de Recerca en Agrigenòmica)
Profound metabolic and structural changes are required for fleshy green fruits to ripen and become colorful and tasty. In tomato (Solanum lycopersicum), fruit ripening involves the differentiation of chromoplasts, specialized plastids that accumulate carotenoid pigments such as β-carotene (pro-vitamin A) and lycopene.

27 p, 5.9 MB Interference with plastome gene expression and Clp protease activity in Arabidopsis triggers a chloroplast unfolded protein response to restore protein homeostasis / Llamas, Ernesto (Centre de Recerca en Agrigenòmica) ; Pulido, Pablo (Centre de Recerca en Agrigenòmica) ; Rodríguez Concepción, Manuel (Centre de Recerca en Agrigenòmica)
Disruption of protein homeostasis in chloroplasts impairs the correct functioning of essential metabolic pathways, including the methylerythritol 4-phosphate (MEP) pathway for the production of plastidial isoprenoids involved in photosynthesis and growth. [...]

19 p, 1.6 MB Specific Hsp100 chaperones determine the fate of the first enzyme of the plastidial isoprenoid pathway for either refolding or degradation by the stromal Clp protease in Arabidopsis / Pulido, Pablo (Centre de Recerca en Agrigenòmica) ; Llamas, Ernesto (Centre de Recerca en Agrigenòmica) ; Llorente, Briardo (Centre de Recerca en Agrigenòmica) ; Ventura, Salvador (Universitat Autònoma de Barcelona. Departament de Bioquímica i Biologia Molecular) ; Wright, Louwrance P. (Max Planck Institute for Chemical Ecology) ; Rodríguez Concepción, Manuel (Centre de Recerca en Agrigenòmica)
The lifespan and activity of proteins depend on protein quality control systems formed by chaperones and proteases that ensure correct protein folding and prevent the formation of toxic aggregates. We previously found that the Arabidopsis thaliana J-protein J20 delivers inactive (misfolded) forms of the plastidial enzyme deoxyxylulose 5-phosphate synthase (DXS) to the Hsp70 chaperone for either proper folding or degradation.

17 p, 3.6 MB Differential subplastidial localization and turnover of enzymes iInvolved in isoprenoid biosynthesis in chloroplasts / Perello, Catalina (Centre de Recerca en Agrigenòmica) ; Llamas, Ernesto (Centre de Recerca en Agrigenòmica) ; Burlat, Vincent (Centre national de la recherche scientifique (França)) ; Ortiz-Alcaide, Miriam (Centre de Recerca en Agrigenòmica) ; Phillips, Michael A. (Centre de Recerca en Agrigenòmica) ; Pulido, Pablo (Centre de Recerca en Agrigenòmica) ; Rodríguez Concepción, Manuel (Centre de Recerca en Agrigenòmica)
Plastidial isoprenoids are a diverse group of metabolites with roles in photosynthesis, growth regulation, and interaction with the environment. The methylerythritol 4-phosphate (MEP) pathway produces the metabolic precursors of all types of plastidial isoprenoids. [...]
