Phylogenetic analysis of GbRLK . (a) Alignment of deduced amino acid sequences of GbRLK and other kinases. (AAB47421, Pto from tomato; BAB08490, protein kinase from Arabidopsis; AAT70497, protein kinase from peach; BAD37843, protein kinase from rice; AAD44031, PK3 from barley; AAK20741, TAK33 from barley; AAB82755, Xa21 from rice). (b) Phylogenetic relationships between GbRLK and other kinase proteins from Gossypium hirsutum and Gossypium barbadense. (c) Phylogenetic relationships between GbRLK and other reported receptor-like kinase proteins from the eudicot Arabidopsis thaliana (AtANXUR1, AEE74120; AtPBS1, AED91858; AtCERK1, AEE76532; AtPR5K, AED94289; AtACR4, AEE79920; AtWAK1, AEE30079; AtRKF3, AEC10923; AtBRI1, AEE87069; AtERECTA, AEC07825; AtCLV1, AEE35762; AtRLK5, AEE85494; AtPERK1, AEE76920; AtPEK12, AEE30401; AtCRK1, AEE29801; AtSD113, AEE28721; AtRKS1, AEE28720; AtCRK5, EFH43988; AtCRK10, AEE84719; AtRLK3, CAA09731; AtFLS2, AED95370; AtLRK13, AEE78027; AtRLK1, AED97394; AtRLK4, BAC42412; AT4G27300; AT4G11890; AT5G24080; AT4G32300; AT5G01540; AT4GO2410; AT3G59750; AT1G09970; AT1G66880; AT2G33580) and some representative members of Oryza sativa (Xa21, AAB82755), Lycopersicon esculentum (LePTO, BAB08490), and Triticum aestivum (TaLRK10, AAC49629). The phylogenetic tree was constructed using the maximum likelihood method in MEGA 5.0. Numbers on internal nodes are the percentage bootstrap support values (1000 re-sampling); only values exceeding 50% are shown.
