Differential responsiveness of each PtLRR-RLK subfamily towards nine GEO (Gene Expression Omnibus) treatments. The frequency of occurrence of PtLRR-RLK genes with up-regulation pattern (A) or down-regulation pattern (B) in each PtLRR-RLK subfamily is presented as a heat-map. Genome-wide transcriptome analysis include callus induction 3 day, callus induction 15 days, shoot induction 3 days and shoot induction 8 days (GSE12152, transcriptome analysis of shoot organogenesis in poplar); LPI5_W_1 wk and LPI1_W_1 wk (GSE16783, wound-induced gene expression changes in Populus fremontii × Populus angustifolia: 1 week; clone RM5); LPI5_W_90 h and Root_W_90 h (GSE16785, wound-induced gene expression changes in Populus: 90 hours); MJ_48 hr (GSE16773, gene expression response of Populus tremuloides cell suspension cultures to methyl jasmonate feeding); LPI2_N-_4w, LPI5_N-_4w, LPI5_N-_8w (Populus leaves under nitrogen limitation, GSE14893); Pt_winter (transcriptional regulation in the winter survival and maintenance mechanism of poplar, GSE21480); root tip, Al treated, at 6 h (Transcriptomic response to aluminum stress in roots of aspen (Populus tremula L., GSE19297); leaf hypoxia and root hypoxia (Effect of hypoxia on gene expression in Grey poplar, GSE13109); 3 day and 7 day (Populus euphratica leaves subjected to infection by Marssonina pathogen, GSE23726).
