Figure 6From: MAP-ping genomic organization and organ-specific expression profiles of poplar MAP kinases and MAP kinase kinasesIntron and exon organization of Arabidopsis MAPKK genes (AtMKKs). Introns and exons are represented by black lines and colored boxes respectively. The length in base pairs of each intron and exon is also indicated. Numbers between brackets correspond to the intron phase. AtMKKs have been grouped according to phylogenetic classification [39].Back to article page
