Signaling pathways such as a small GTPase mediated signal transduction was over-represented in broad without peak promoters (Additional file 3).
GO analyses of genes up-regulated in fiber initials using UniProt cognates identified genes associated with a small GTPase mediated signal transduction pathway.
Based on its orthology with Arabidopsis RDR2 and phenotypes for maize mutants, the current model for MOP1 activity is that it functions in a small RNA mediated pathway to direct DNA methylation and heterochromatin formation at transcriptionally silenced loci.
Six genes (Contig10324, Contig85, Contig16430, Contig2338, Contig6782, Contig1658) involved in a small GTPase mediated signal transduction pathway (P = 0.0169) were up-regulated in 1 dpa fiber and persisted in 10 dpa fiber [ 32, 33].
RNA-directed DNA methylation (RdDM) is a small RNA-mediated epigenetic modification that contributes to transcriptional silencing of transposons and repetitive sequences in plants.
However, the changes in single channel properties cannot account for the increase in mEPSC amplitude or the inward rectification of AMPARs in the GluR1-S845A mutants, which should display a smaller GluR1-mediated current.
A small-molecule-mediated interaction between a CRL and its substrate is not unique to the F-box protein TIR1.
