All together, genes involved in primary wall modification, wood growth, and tracheid dimensions were differentially expressed in branch wood of Populus, providing more clues to the molecular mechanisms affecting wood formation.
The majority of these transcripts were more highly expressed in branch tips (wnts 2, 2b, 5a, 5b, 8a & 8b, lrp1, krem1, and dkk3), but five genes showed higher expression in colony bases (wnts 7a & 7b, lrp6, sox17 and casein kinase I).
According to previous in situ results, SNB is initially expressed in the branch meristem and spikelet meristem, and is then primarily restricted in the boundary region of the spikelet and glume primordia.
As Z3 is highly expressed in panicle branches, similar to the expression levels in leaf blade (Fig. 6b), it is plausible that the Z3 protein also functions in translocating metal ions into grains.
Timeless, a transcription factor involved in the regulation of circadian rhythms, and expressed in the branching ureteric tips, has also been shown to regulate ureteric branching morphogenesis [ 28].
Na,K-ATPase alpha-1 and alpha-3 were lightly expressed in MMA branches and nerve fibers, but not at capillaries.
Vascular endothelial growth factors (VEGF), necessary for development of the lung vasculature, are expressed in both branching tubular airways and vascular mesenchymal cells.
We demonstrate that Fras1 is expressed in UB branches and that renal agenesis occurs with high penetrance in homozygous Fras1 null mutant blebbed (bl) mice maintained in a C57BL6J background.
We demonstrate that Fras1 is expressed in the branching ureteric bud (UB), and that renal agenesis occurs in homozygous Fras1 null mutant blebbed (bl) mice on a C57BL6J background.
In support of this idea, GLP-1 receptors have been detected immunohistologically in human portal vein sections, with corresponding GLP-1 receptor mRNA expression in the nodose ganglion (the inferior ganglion of the vagus nerve) [ 12], suggesting that GLP-1 receptors are expressed in afferent branches of the vagus, including those innervating the portal vein.
FK1 on Chr7 only was expressed in the feather branch, but not in the rachis, ramus, or calamus (fig. 5 G1 – G5).
