The number of proteins of interest and DPs in the protein repertoires from maize inbred lines M9 and SM9 under different photoperiods.

<p>The statistics were based on manual searching from GO categorization instead of simple annotation description of proteins in terms of the key items such as “photoperiodism”, “flower”, “cold”, and “salt/water/desiccation”. Some proteins involved multiple biological processes; therefore, the statistical figures may overlap. The boldface figures in the circles indicate the number of proteins under the items. The italics figures in the small circles represent the number of DPs. DPs, differential proteins in abundance; GO, Gene Ontology.
