Lycopersicon esculentum LeGPA1 sequence analysis. a LeGPA1 amino acid sequence alignment with other plant species. b Phylogenetic relationship between LeGPA1 protein and GPA1 proteins from other plant species. MEGA 5.1 was used for phylogenetic tree construction, with protein sequences used for such construction being from GenBank as follows: Nicotiana tomentosiformis (XP_009601362.1); Nicotiana benthamiana (ACR77527.1); Ricinus communis (XP_002516152.1); Hevea brasiliensis (XP_021680157.1); Abrus precatorius (XP_027368925.1); Cannabis sativa (XP_030489435.1); Trema orientale (PON39630.1); Capsicum annuum (XP_016537648.1); Solanum tuberosum (NP_001275141.1); Solanum lycopersicum (NP_001292984.1); Solanum chilense (TMX03447.1); and Solanum pennellii (XP_015083292.1). Bootstrap replicate values (1000×) were obtained. c Prediction of the conserved domain of LeGPA1
