HDG2 is highly enriched in meristemoid population of stomatal cell lineages. (A) HDG2 absolute and relative expression levels among wild-type and stomatal mutants enriched in specific epidermal cell populations. Absolute expressions (dark gray) are from ATH1 microarray data; relative expressions (light gray) are from qRT-PCR analysis. Data are mean values of triplicates; error bars indicate s.e.m. Col, wt; spch, pavement-cell only; mute scrm-D, overwhelmingly enriched in meristemoids; scrm-D, stomata-only epidermis. Below each graph are confocal images of cotyledons from corresponding genotypes. (B) Stomatal-lineage accumulation of HDG2 transcriptional reporter (HDG2pro::nls-3xGFP) in seedling epidermis. (C) Stomatal-lineage accumulation of HDG2 translational reporter (HDG2pro::HDG2-GFP) in 10-day-old abaxial cotyledon epidermis. Scale bars: 20 μm. (D) Expression levels of AtML1 and PDF2 compared with HDG2 among wild-type and stomatal mutants.
