      Article
      Open Access
      The MADS-domain transcription factor SEEDSTICK (STK) controls several aspects of plant reproduction. STK is co-expressed with CESTA (CES), a basic Helix-Loop-Helix (bHLH) transcription factor-encoding gene. CES was reported ...
    • Maternal control of PIN1 is required for female gametophyte development in Arabidopsis
