An Arabidopsis gene encoding a C2H2-domain protein with alternatively spliced transcripts is essential for endosperm development.

abstract：:Primary adhesion of zoospores of the green macroalga Enteromorpha to substrata involves a massive release of adhesive glycoproteins from Golgi-derived, membrane-bounded vesicles in the anterior region of the spore, followed by rapid curing. This process is sensitive to low concentrations (5-10 microg x ml(-1)) of the ...
