Fig. 3From: Genome-wide identification and expression analysis of SWEET gene family in Litchi chinensis reveal the involvement of LcSWEET2a/3b in early seed developmentPhylogenetic relationship, gene structure and conserved motif analysis of LcSWEET genes. a The neighbor-joining phylogenetic tree was constructed with MEGA7 using amino acid sequences of LcSWEETs, and the bootstrap test replicate was set as 1000 times. b The motif composition of LcSWEET proteins. Five motifs were displayed in different colored rectangles. c Exon-intron structure of 16 LcSWEET genes. Yellow roundrectangles represent exons and black lines with same length represent introns. Blue roundrectangles indicate the UTR region. d The amino acid sequences of 8 motifs of LcSWEET proteins were showedBack to article page
