Lineage-specific cascades suggest regulatory pathways. (A) Expression of a subset of E-lineage-specific patterns arranged by onset time (E-specific expression identified using the fivefold lineage cutoff). (B) Reporters with patterned expression in the E lineage. (C) Timing of all E-specific patterns. (D) Lineage-aligned reporter expression patterns of eight genes showing progressive restriction of expression in the daughters of AB (tbx-38), ABal (ceh-32 and hlh-26), ABalp (pha-4 and ceh-43) and ABalp daughters (tbx-11), granddaughter (alr-1), and in the left ASK neuron derived from this lineage (ttx-3). A poster-sized curated set of patterns distinguishing cells of all lineages is available as a Supplemental Poster.
