Genomic positions of the PRLIP genes and their phylogenetic
relationships. A, The arrangement of the PRLIP1 (At5g24210),
PRLIP2 (At5g24200), PRLIP4 (At5g24220), PRLIP5 (At5g24180), PRLIP6 (At5g24230), and PRLIP7 (At5g24190)
genes on chromosome 5 of Arabidopsis. A 37-kb region, where these genes are in
tandem positions, is projected in a bigger scale. B, Unrooted phylogenetic
tree of the Arabidopsis PRLIP proteins of the tandem repeat and three
additional Arabidopsis paralogs (PRLIP3:At2g05260, PRLIP8:
At5g50890, and PRLIP9:At4g10955) and their rice (Oryza
sativa) homologs (Q943F9, Q8S2P2, Q8RZ95, and Q8W0F0). The protein
sequences were aligned with ClustalW software, and an unrooted tree was
constructed using the TreeView program. The scale value of 0.1 indicates 0.1
amino acid substitutions per site. I, subgroup I; II, subgroup II; and III,
subgroup III.
