No full textTraceability, which is the ability to trace the history, application or location of an entity, by means of recorded identifications, is becoming the more and more important for the certification of food products. We have adopted a proteomic approach to trace three commercial varieties of emmer. We have analysed the protein pattern using two-dimensional electrophoresis. We have moreover compared amylolitic isoforms of the three emmer varieties. Our results have showed that each variety has some specific spots, which could be used as a molecular marker. We have also observed differences in the amylolitic activity between the three varieties of emmer

Aconitase: To be or not to be inside plant glyoxysomes, that is the question
No full textAfter the discovery in 1967 of plant glyoxysomes, aconitase, one the five enzymes involved in the glyoxylate cycle, was thought to be present in the organelles, and although this was found not to be the case around 25 years ago, it is still suggested in some textbooks and recent scientific articles. Genetic research (including the study of mutants and transcriptomic analysis) is becoming increasingly important in plant biology, so metabolic pathways must be presented correctly to avoid misinterpretation and the dissemination of bad science. The focus of our study is therefore aconitase, from its first localization inside the glyoxysomes to its relocation. We also examine data concerning the role of the enzyme malate dehydrogenase in the glyoxylate cycle and data of the expression of aconitase genes in Arabidopsis and other selected higher plants. We then propose a new model concerning the interaction between glyoxysomes, mitochondria and cytosol in cotyledons or endosperm during the germination of oil-rich seeds
