Mastoparan induces Ca(2+)-dependent deflagellation of the unicellular green alga Chlamydomonas moewusii Gerloff, as well as the activation of phospholipase C and the production of inositol 1,4, 5-trisphosphate (InsP(3); T. Munnik et al., 1998, Planta 207: 133-145).

We previously reported that transcripts for a 30-kD nodulin (Npv30) are very abundant in the nodule. In this paper we describe the isolation and characterization of Npv30 cDNA and genomic clones. Npv30 has the following characteristic features: (a) a putative signal sequence at the deduced amino-terminal region, (b) a proline-rich stretch at the carboxy terminus, and (c) a characteristic domain of four cysteines that resemble metal-binding sites.

Alcohols induce mating-structure activation in Chlamydomonas eugametos gametes. From the effect of ethanol on the (32)P-labelling of polyphosphoinositides, we conclude that the synthesis of these lipids is stimulated. Biologically inactive concentrations of ethanol (<6%) had no effect on synthesis, but 6-8% ethanol stimulated synthesis for upto 60 min.
