La fosfoenolpiruvato carboxilasa (PEPC; EC 4.1.1.31) es una enzima citosólica multifuncional que está implicada en procesos clave del metabolismo del carbono y del nitrógeno. La PEPC cataliza la ß-carboxilación irreversible del fosfoenolpiruvato (PEP) para formar oxalacetato (OAA) y fosfato inorgánico (Pi). Realiza el primer paso de...

To reduce the impact on the environment and enhance the sustainability of resources, it is necessary to promote and strengthen the use of landrace cultivars that advocate regenerative agriculture. In this study, the growth and development as well as the anaerobic digestion (AD) of six different landrace cultivars, two commercial hybrids...

Phosphoenolpyruvate carboxylase (PEPC; EC 4.1.1.31) is an enzyme family with pivotal roles in plant carbon and nitrogen metabolism. A main role for non-photosynthetic PEPC is as anaplerotic enzyme to load tricarboxylic acid (TCA) cycle with carbon skeletons that compensate the intermediates diverted for biomolecule synthesis such as amino...

Background: The application of microorganisms as bioestimulants in order to increase the yield and/or quality of agricultural products is becoming a widely used practice in many countries. In this work, five plant growth-promoting rhizobacteria (PGPR), isolated from cultivated rice paddy soils, were selected for their plant growth-promoting...

Phosphoenolpyruvate carboxylase (PEPC) is an enzyme family with central roles in carbon and nitrogen metabolisms. In order to obtain knowledge about the function of specific PEPC isoenzymes, we have characterized RNAi sorghum lines with decreased level of PPC3 (Ppc3 lines). PPC3 is the main root PEPC, and participates in responses to salinity...

Phosphoenolpyruvate carboxylase (PEPC) plays central roles in photosynthesis, respiration, amino acid synthesis, and seed development. PEPC is regulated by different post-translational modifications. Between them, the phosphorylation by PEPC-kinase (PEPCk) is widely documented. In this work, we simultaneously silenced the three sorghum genes...

Phosphoenolpyruvate carboxylase (PEPC) is a carboxylating enzyme with important roles in plant metabo-lism. Most studies in C4plants have focused on photosynthetic PEPC, but less is known about non-photosynthetic PEPC isozymes, especially with respect to their physiological functions. In this work, weanalyzed the precise roles of the sorghum...
