dc.description.abstractWhile the molecular response of salinized plants in the short-medium term (hours-days) has been broadly studied, the knowledge about the nature of the genes involved in maintaining homeostatic conditions the long term (months-years) has remained elusive. With this aim, we have analyzed the transcriptome of leaves from citrus plants acclimated to moderate salinity (2 years with NaCl 30 mM). Through functional genomics, using the 7K cDNA chip from ¿Consorcio Valenciano de Genómica Funcional de Cítricos¿, the transcriptome of citrus plants acclimatized to salinity was analyzed in mature leaves (8 months) and immature leaves (2 months). Although immature leaves accumulated low levels of chloride (0.51%±0.06), they exhibited high responsiveness to salinity (1,211 differential-responsive genes) compared with mature leaves, which cumulated higher chloride levels (1.05% ± 0.01), and showed a lower number of differentially-responsive genes (100 genes). Immature leaves induced functional categories that were not induced in mature leaves, like ¿cell wall biosynthesis¿, ¿metabolism¿, ¿defense¿, ¿secretion and membrane traffic¿, ¿water transport¿ and ¿antioxidant activity¿. On the other hand, the degree of coincidence was higher in the group of genes that were repressed by salinity. Both mature and immature leaves repressed genes mostly involved in ¿stress response¿. We highlight how the same plant organ in different developmental stages show huge differences in the amount and nature of genes which are responding to an abiotic stimulus.-
