Figure 8.—

Ccc1p-like membrane proteins in plants. (A) Ccc1p-like Arabidopsis and rice (Os) proteins were aligned as in the Figure 2 legend. Names of proteins with ILR3-regulated accumulation of the encoding mRNAs are shown in black, and others are in gray. Identical residues in at least four proteins are shaded in black; chemically similar residues are shaded in gray. Solid lines over the alignment indicate predicted transmembrane domains in At1g21140; lines below the alignment indicate predicted transmembrane domains in At2g01770. (B) CCC1-like genes are expressed in various tissues. Bars represent average transcript level from Genevestigator (Zimmermann et al. 2004) compiled microarray data plus standard errors. Genes depicted in solid bars are ILR3-regulated; those shown in shaded bars are not. Expression data are shown for entire seedlings (S; n = 320 chips), roots (R; n = 187), rosettes (L; n = 576), inflorescences (I; n = 139), and cell suspension (C; n = 42) of wild-type Col-0. At3g43630 is not shown because the ATH1 chip lacks probes specific for this transcript.
