In contrast, vertebrate species, particularly mammals, typically exhibit "global" DNA methylation patterns (Robertson 2005; Rollins 2006; Chen and Riggs 2011) where candidate methylation sites across the entire genome are completely methylated, except for those in promoter regions where the methylation level varies highly among different tissues, cells, growth conditions, and developmental stages.
The reduction in promoter accessibility at most genes in XSyx4-CG3603 is apparently not sufficient to cause detectable changes in gene expression, except in the case of white.
DNA binding motifs of Pdr1/3p were found in promoter regions of PDR3, YAP5, PDR6, and RPN4; Yap1p binding sites in all six transcription factor genes except for PDR1; and Hsf1p sites in all six genes except for PDR1.
All probes showed increased dosage change, except the probe in the promoter, in agreement with the MLPA results.
Histochemical staining of GUS activity during reproductive growth was also observed in the petiole of green leaves and the split margins in siliques in all promoter constructs except the GmPRP2p-471, buthehexpressionon level was much lower than in roots.
High scoring SphR binding sites are found in their promoter regions except for CYA_1059 in Aprime, CYB_0274 in Bprime and PMT9312_0720 in MIT9312.
Indeed, we detected no T2D-related differential methylation satisfying our significance criterion except for a single CpG in the promoter of CIDEB that, in turn, displays no significant differential DNA methylation in T2D pancreatic islets.
Sequence analysis for two female-specific genes revealed gene duplication except for differences in the promoter regions.
For instance, in the experimentally defined transcriptional unit containing the genes deoC, upp, MHP7448_0525, lon and tuf, all the genes, except MHP7448_0525, contain promoter sequences in their upstream regions (with scores varying from 8.4 to 11) (data not shown).
Most of the genes here analyzed exhibited CpG islands in their promoter sequences, except for MITF and TNF.
