Phylogenetic analysis of MAPKKKs from banana, rice and Arabidopsis. The Neighbor-joining (NJ) tree was constructed using ClustalX 2.0 and MEGA 5.0 software with 1000 bootstrap replicates. Signs of different shapes represent MAPKKK proteins from banana (red round, Ma), rice (green rhombus, Os) and Arabidopsis (blue triangle, At).
