Fig. 1From: Putative trehalose biosynthesis proteins function as differential floridoside-6-phosphate synthases to participate in the abiotic stress response in the red alga Pyropia haitanensisConserved domains in the P. haitanensis TPS family. The black bar indicates the amino acid sequence length of the complete ORF of PhTPS1–4; the red arrows on the bar indicate the recombinant expression region; the green, purple, and orange area on the bar show the CBM20, TPS, and TPP functional domains, respectively; the light pink area in the domains indicates that the related sequence segment had low homology with the conserved superfamily recorded in NCBIBack to article page
