Characterization of SlNAC063 protein. (A) Sequence alignment of tomato SlNAC063 with SlNAC090, and Arabidopsis ANAC072, ANAC055, and ANAC019 proteins. The conserved NAC domains are indicated by red boxes, with five highly conserved subdomains A–E indicated by two-way arrows. C1 and C2 domains are indicated by green and red boxes, respectively. Predicted phosphorylation sites are indicated by arrows, S, serine; T, threonine; Y, tyrosine. (B) Phylogenetic tree analysis of SlNAC063 with other subgroup IIb NAC proteins from tomato, rice, and Arabidopsis thaliana and with two previously reported NAC proteins functionally characterized with respect to Al stress, i.e., rice bean VuNAR1 and Arabidopsis SUPPRESSOR OF GAMMA RESPONSE 1 (SOG1). Triangle: the position of SOG1. Star: the position of SlNAC063.
