Figure 7From: SUMO E3 ligase AtMMS21 is required for normal meiosis and gametophyte development in ArabidopsisSUMOylation profiles of pollen proteins in wild-type and mms21-1 plants. Pollen protein extracts were analyzed by protein gel blots using anti-SUMO1polyclonal antibodies to detect SUMO-protein of wild-type and mms21-1. Arrows indicate missing SUMO conjugates in mms21-1. Coomassie brilliant blue staining of total protein was used as the loading control.Back to article page
