UNLABELLED • PREMISE OF THE STUDY Sperm cell differentiation in ferns involves the origin of an elaborate locomotory apparatus, including 70+ flagella, and the structural modification of every cellular component. Because arabinogalactan proteins (AGPs) are implicated in molecular signaling and in regulation of plant development, we speculated that these glycoproteins would be present during spermiogenesis in ferns.• METHODS Using β-glucosyl Yariv reagents that specifically bind to and… CONTINUE READING
