Fig. 2From: Genome-wide identification and expression analysis of the NAC transcription factor family in tomato (Solanum lycopersicum) during aluminum stressThe exon-intron structure of SlNAC genes in accordance to the phylogenetic relationship. The unrooted phylogenetic tree was constructed with 1000 bootstrap based on the full length sequences of SlNACs. Exon-intron structure analysis of SlNAC genes was performed by using the online tool GSDS. Lengths of exons and introns of each SlNAC gene were exhibited proportionallyBack to article page
