The protein alignment composite of 51 NOI containing proteins from monocots, dicots and moss was generated using the Ensembl plant database (http://plants.ensembl.org/) . The 51 NOI containing proteins were selected on the basis of their sequence homology to AtRIN4. Green bars show areas of amino acid alignment while the white areas are gaps in the alignment. Dark green bars indicate the consensus alignment in the collapsed tree. The regions corresponding to the C- and N- NOI domains are shown by red bars. The highest level of conservation in sequence is seen in the C-NOI domain, followed by the N-NOI domain and the region representing the conserved C-terminal cysteines.
