The predicted expression levels of several other highly expressed genes of specific regulatory proteins are listed in Table 1.
We then quantified by qPCR the relative expression levels of several significantly differentially expressed genes from the GCOS Affymetrix method.
The expression levels of several genes in the tricarboxylic acid cycles were upregulated with xylose.
Moreover, the expression levels of several interferon-stimulated genes (ISGs) were measured by quantitative real-time PCR.
However, Suzuki et al. (2015) reported that NAA decreased endogenous auxin levels and the expression levels of several YUC genes in Arabidopsis.
Expression levels of several Yap1/p73 and Yap1/TEAD1 target genes were monitored by quantitative reverse transcription-polymerase chain reaction (RT-PCR).
The RNA repeats specifically sequester or change the expression levels of several RNA-binding proteins, leading to aberrant splicing of many target genes.
The expression levels of several auxin signaling genes, including IAA1, IAA2, and IAA3, as well as several auxin binding and transport genes, decreased significantly in ftsh4-4 plants.
Cave and surface A. mexicanus differ in the expression levels of several genes, including the gene sonic hedgehog (shh) whose expression is higher and differently situated in cavefish than in surface fish.
We therefore examined expression levels of several BR-synthetic genes in KYJ and smg11 panicles, including DWARF4, DWARF11 and BRD1 (Hong et al., 2002; Mori et al., 2002; Tanabe et al., 2005; Sakamoto et al., 2006).
In addition, expression levels of several genes of a pathway may need to be tuned to avoid accumulation of potentially inhibitory intermediates as demonstrated for C. glutamicum engineered for decaprenoxanthin overproduction [23].
