Phylogenetic tree showing the relationship of rice ROS-bZIP1 (Os08g43090) to known classes of plant bZIP transcription factors. Scheme is based on genome-wide survey and classification of Arabidopsis bZIP proteins [15]. ROS-bZIP1 belongs to Class-I, which also includes the RF2a, RF2b and VSF-1 of rice and VIP1 of rice and Arabidopsis. All Arabidopsis genes included in this neighbor-joining tree are identified by standard genomic locus numbers. Phylogenetic tree was assembled using clustalW.
