Expression profiles of LbPLS1 , LbTSP2-A , LbTSP2-B , LbTSP2-C and LbTSP2-D in different tissues from Laccaria bicolor . LbPLS1 and LbTSP2-A, LbTSP2-B, LbTSP2-C and LbTSP2-D expressions were measured by 60-mer oligoarrays (NimbleGen) using RNA extracted from mycorrhiza, mycelia and fruiting bodies (carpophores). LbPLS1, LbTSP2-A, LbTSP2-B, LbTSP2-C and LbTSP2-D expressions were calculated relative to the transcripts levels of the constitutively expressed gene EIF-5A (LACBI1_192615). Each data point is the mean between values of two biological replicates and a third value corresponding to the mean of two biological replicates. Standard deviation is indicated by error bars. PLS1 is constitutively expressed in all tissues, LbTSP2-A transcripts are barely detectable in comparison to LbTSP2-B, LbTSP2-C and LbTSP2-D transcripts that are expressed in all tissues. LbTSP2-B is strongly expressed in mycorrhiza and mycelia whereas LbTSP2-C and LbTSP2-D are up-expressed in fruiting bodies and in mycorrhiza, respectively.
