Since PCs are normally formed in (Df enX31/+) heterozygous embryos ([12] and data not shown), but not in (Df enX31/Df gsbX62) embryos (Figure 6B2), we asked which NBs required a normal level of GsbN expression to form the PCs.
Thus, two regions of the INO promoter contain regulatory sequences sufficient to promote the specific pattern of INO expression in the ovule, and both require additional sequences to generate a normal level of expression.
First, there's a question of what constitutes a "normal" level of spending and saving.
A normal level of alertness.
And returning to a normal level of brand spending.
Arabidopsis allele-specific imprinted genes encode multiple types of proteins, including a putative transcription factor (HDG3), a heat shock protein, a phosphoinositide phosphatase (AT3G14205), three chromatin proteins, and a gene required for normal levels of phytic acid accumulation in seeds (Kim and Tai, 2010).
In support of a role in cell proliferation, SpRunt is required for normal levels of cyclins B and D, which are expressed in a proliferation-specific pattern similar to that displayed by SpRunt [ 19, 20].
ZIP1 is a transverse filament protein of the synaptonemal complex that is required for normal levels of meiotic recombination and pairing between homologous chromosomes during meiosis.
By comparing H2A.Z binding to global gene expression in budding yeast strains engineered so that normally unstable transcripts are abundant, we show that H2A.Z is required for normal levels of antisense transcripts as well as sense ones.
In this study, however, we found that in developing leaves under excessive light conditions and in mature leaves beginning at the reproductive stage, even high levels of OsPORA mRNA and protein failed to fully substitute for OsPORB activity, which is required for normal levels of Chl synthesis.
