Gene Expression Profiles in mur4-1, prl1, and mur4-1 prl1.

(A) Upregulated genes in mur4-1 were classified into six clusters according to their expression profiles in the wild type, mur4-1, prl1, and mur4-1 prl1. Cluster numbers and mutant alleles are indicated as follows: C, Col-0; m, mur4-1; p, prl1; mp, mur4-1 prl1.

(B) Downregulated genes in mur4-1 were classified into six clusters according to their expression profiles in the wild type, mur4-1, prl1, and mur4-1 prl1. Cluster numbers and mutant alleles are indicated as in (A).
