Fig. 3From: Genome-wide search and structural and functional analyses for late embryogenesis-abundant (LEA) gene family in poplarChromosomal localization of the PtrLEA genes and gene duplication events. a Distribution of the genes on chromosomes of poplar, the small blue are represents pairs of tandem repeated genes. b Duplicate pairs of the PtrLEA genes in poplar. The red lines represent collinear pairs of the PtrLEA genes, while the gray lines indicate collinear pairs of all poplar genesBack to article page
