Project description:Human A549 lung epithelial cells were exposed directly at the air-liquid interphase towards combustion aerosols of wood burning. The goal was to compare the responses towards different wood and burning conditions. Beech log woods were burnt in a modern masonry heater, soft wood pellets were burnt in a pellet boiler.

Project description:Cork quality is a technological trait of large interest for the Mediterranean cork industry. Our manuscript analyses the proteins and phenolics of cork producing cells in order to collect data about the molecular/biochemical pathways determining cork quality. To the best of our knowledge, this information is sparse in the research and technological community but it would be a valuable tool for breeding. We show that cells leading to the production stoppable (highly valued) and non-stoppable cork have contrasting profiles regarding soluble and cell-wall bound phenolics. The difference was also observed when considering the protein profiles but the discrimination between cork quality groups is not as remarkable as when considering phenolics. In any case, the mitochondrial metabolism points out for higher energy demand in non-stoppable cork producing cells.

Project description:The phellogen or cork cambium is a bifacial stem cell population from which derivatives are formed by periclinal divisions and specified on opposing sides as phelloderm (inwardly) and phellem or cork (outwardly). Altogether the three layers constitute the periderm which covers and protects the radially-grown organs (stems, roots and tubers) and wounded tissues from dehydration and pathogen attack. The phellem is the final responsible of the protective function of periderm and despite its vital importance, just the suberin biosynthetic process has been studied molecularly while other processes are poorly understood. To shed some light on the phellem cell development from its formation to its final maturation, we used the innercork living material of cork planks extracted from cork oak (Quercus suber) in which we analysed the transcriptome at three time-points: at the beginning (April), maximum (June) and final (July) cork seasonal growth. Since cork presents seasonal growth and the process from phellogen derivative proliferation and specification to phellem cells is continuous, the time-course cork samples were used to approach the phellem cell formation and development. The June enrichment of phellem cells undergoing suberization was confirmed transcriptionally, observing highest expression of suberin-related genes in this month, thus validating our strategy. To highlight the major molecular processes embracing from phellogen to mature phellem cell, the differentially expressed genes between time-points were clustered based on their expression pattern. April transcriptome upregulates the processes involved in the meristem proliferation and maintenance and the triggering of cell differentiation, in agreement with the enrichment of phellogenic cells from which phellem cells are specified. The processes upregulated in Juny and July cork samples, were secondary metabolic processes compatible with the biosynthesis of secondary metabolites deposited within phellem cell wall such as suberin, lignin, extractives including fatty aciyl-derived compounds and triterpenes and also soluble aromatic compounds. The processes with a maximum in July showed upregulation of polyssacharides- and lignin-related processes compatible with a reinforcement of the cork cell wall, presumably related with the latecork formation with smaller and thickened-cells at the end of the growing season. For the above mentioned processes, we discuss the putative function of the most relevant genes in the context of phellem ontogeny. This work provides the most important molecular mechanisms during phellem cell development and provide relevant data for the understanding of the seasonal growth of cork, a material of important circular economic value.

Project description:Wood maturation produces two distinct wood tissues: juvenile wood (JW) and mature wood (LW), which are the major cause of wood qaulity variation within a tree. We investigate transcriptome reorganization during wood maturation process in radiata pine using a newly developed 18k cDNA microarrays.
