Sequence analysis of CESA1 T157 and S162 phosphorylation site conservation. (A) Amino acid sequences of CesA1 homologs from various plants species were aligned in ClustalX2, and the amino acid sequence regions surrounding the T157 and S162 phosphorylation sites in CesA1 are presented. The residues corresponding to these positions are labeled above the alignment. (B) This alignment was used to generate a sequence logo (weblogo.berkeley.edu/logo.cgi) illustrating the conservation of each amino acid surrounding the T157 and S162 phosphorylation sites (indicated with asterisks). The number of letters at each position indicates the types of amino acids found in each position of the alignment, whereas the height of each letter indicates increasing conservation of a particular residue.
