From: Adaptive expansion of the maize maternally expressed gene (Meg) family involves changes in expression patterns and protein secondary structures of its members

Figure 5

Specific Meg homologs are highly expressed in maize endosperm. (A) Bright-field micrograph of a maize endosperm at 8 days after pollination (DAP), showing the basal endosperm transfer cell (BETC), peripheral endosperm (PE) and starchy endosperm cell (SEC) layers. These three tissue types were isolated by cryo-microdissection, and gene-specific transcripts were evaluated by RNA-seq. Scale bar: 0.5 ○m. (B) Transcript levels of each Meg gene in the BETC, PE and SEC. The six highly-expressed genes are highlighted in green. Note that Meg transcripts are detected exclusively in BETC. (C) Abundances of Meg proteins in the maize endosperm at three developmental stages. The histogram is based on results from searching the maizeproteome.ucsd.edu. Meg proteins not found in the proteome database are omitted from the histogram. The x-axis is scaled to the normalized arbitrary unit according to the maize proteome database.
