This FT/FD heterodimer activates the downstream floral meristem identity gene APETALA1 (AP1) [ 12, 15, 16].
This snapshot of the major parasitic transcripts showed that 35 out of 106 tags (33%) mapped unambiguously to their genes with 100% sequence identity (downstream stop codon).
These data show the heterogeneous levels of aPKC and its subsequent polarisation depend on the acquisition of PrE identity downstream of FGF signalling.
Conversely, any transcriptional regulator expressed only in dHbl or dHbm neurons could only function as an effector of that specific differentiated identity, downstream of whatever factors mediate fate selection.
DLF1, homologous to Arabidopsis FD, form a complex with ZCN8 (maize FT protein) to activate downstream floral organ identity genes, such as ZMM5, the homolog of Arabidopsis SOC1 in maize.
However, several studies in eudicot species have failed to provide unambiguous support for a hypothesis that development of unisexual flowers would involve alterations in the expression patterns of the B- or C-function genes, which indicates that the genetic mechanisms in sex determination must act downstream of organ identity [ 60- 64].
Between Sw43, QW170, and QW218, all 18 nt were identical, but identities decreased downstream of this motif.
Activation of a G protein-coupled receptor (GPCR) triggers downstream signalling pathways whose identity is determined not only by the genetic background of the cell, but also by the interacting ligand.
Genes downstream vary both in identity and orientation, even among isolates of the same species (B. bronchiseptica), suggesting this region is a hotspot for recombination.
The functions of these transcription factors ultimately serve to establish chamber identity, so downstream effectors direct appropriate cell differentiation linked to the anatomical position within the heart.
