The analysis of cell fate patterning during the vulval development of Caenorhabditis elegans has relied mostly on the direct observation of cell divisions and cell movements (cell lineage analysis). However, reconstruction of the developing vulva from EM serial sections has suggested seven different cell types (vulA, vulB1, vulB2, vulC, vulD, vulE, and(More)
Bas1p and Bas2p (Pho2p) are Myb-related and homeodomain DNA binding proteins, respectively, required for transcription of adenine biosynthetic genes in Saccharomyces cerevisiae. The repression of ADE genes in adenine-replete cells involves down-regulation of the functions of one or both of these activator proteins. A LexA-Bas2p fusion protein was found to(More)
The great-grandprogeny of the Caenorhabditis elegans vulval precursor cells (VPCs) adopt one of the final vulA, B1, B2, C, D, E, and F cell fates in a precise spatial pattern. This pattern of vulval cell types is likely to depend on the cis-regulatory regions of the transcriptional targets of intercellular signals in vulval development. egl-17, zmp-1, and(More)
