Abstract

The Class V zygote-specific gene from Chlamydomonas reinhardtii has been cloned and sequenced. This gene encodes a polypeptide of 86 amino acids, which contains a signal peptide and 6 cysteine residues arranged in an inverted symmetrical repeat. The Class V gene product is postulated to be a component of the zygote cell wall. Southern analysis revealed two tandemly oriented and closely linked copies of the Class V gene, designated A and B. The A gene appears to be a pseudogene, based on analysis of Class V cDNAs, primer extension with gene-specific primers, and Northern analysis which failed to detect an A gene transcript. Genetic analysis using a related Chlamydomonas species that lacks the A gene, but which produces normal zygotic progeny, further indicates that the A gene is not required for zygote development.
