Functional analysis of the differently expressed genes between the contrasting N treatments. (a) Top ten categories of the genes induced by nitrogen deprivation and repressed by nitrogen luxuriant supply. (b) Top ten categories of the genes repressed by nitrogen deprivation and induced by nitrogen luxuriant fertilization. (c) Number of genes differently expressed in the five most represented categories of Eucalyptus DEG. Genes induced by nitrogen deprivation and repressed by nitrogen luxuriant supply are presented in dark green for Eucalyptus and light green for Populus[13]. Genes repressed by nitrogen deprivation and induced by nitrogen luxuriant fertilization in dark red for Eucalyptus and light red for Populus. FUNCAT software [35] categories: SL, subcellular localization; PS, protein synthesis; PWBF/CR, protein with binding function or cofactor requirement; M, metabolism; CTFR, cellular transport, transport facilitation and transport routes; IWE, interaction with the environment; CRDV, cell rescue, defense and virulence; UP, unclassified proteins; PF, protein fate; SIWE, systemic interaction with the environment; T, transcription. (a) and (b) values in %.
