Fig. 2From: Identification and characterization of HAK/KUP/KT potassium transporter gene family in barley and their expression under abiotic stressPhylogenetic relationship and sequence characteristics of HvHAK proteins. a Phylogenetic tree of HvHAK proteins. b Conserved motifs and domains of HvHAK proteins. Conserved domains and motifs were indicated on the upper side and lower side of protein sequences, respectively. c Structure of HvHAK genes. Introns and exons were represented with black lines and green boxes, respectivelyBack to article page
