New paper on the functional diversification of exocyst subunits published in Plant Journal

The exocyst complex is an octameric evolutionarily conserved tethering complex engaged in the regulation of polarized secretion in eukaryotic cells. In this paper, we focused on systematic comparison of two isoforms of the SEC15 exocyst subunit, SEC15a and SEC15b. We have documented that both isoforms are parts of the exocyst complex and play dominant roles in the exocyst-dependent secretion in the male gametophyte or sporophyte, respectively.
