Hierarchical clustering of CUTs based on their differential expression during abiotic stress. The expression levels of 109 CUTs in cpl1-2 plants and in wild-type plants subjected to Fe deficiency (Fe-free nutrient solution for 24 h; Gene Expression Omnibus accession GSE15189), ABA (1 µm ABA for 3 h; NASCArray accession 176), salt (130 mm NaCl for 6 h; NASCArray accession 139), or mannitol (300 mm mannitol for 12 h; NASCArray accession 140) were subjected to hierarchical clustering using the Pearson correlation distance and average linkage rule.
