Conversely, Klf2 and Tiparp displayed pulse-like rapid upregulation within 1 3 h followed by a decline in transcript level, which in the case of Klf2 reaches baseline; a similar biphasic pattern of expression was observed for Tgfb3, Il15ra and Mt2.
Microarray studies of shoot tissues of Vitis vines exposed to water-deficit stress also showed a decline in transcript abundance for cell wall metabolism genes [ 24], and similar processes appear to occur in berries.
The role of peroxynitrite is supported by the fact that exposing cells to this anion causes a decline in mtRNA transcripts (Ballinger et al., 2000).
Extending the temporal window of the assay, we observed a decline in the transcript abundance of these UPR targets until 48 h (Fig. 1C).
The endo/ecodormancy transition (SEP to NOV) was characterized by a further decline in transcripts participating in cellular processes as well as primary and secondary metabolism functional categories, similar to what was observed in the para/endodormancy transition.
Northern blot analysis indicated a decline in the ATP sulfurylase transcript levels during seed development.
Furthermore, Iglesias-Acosta et al. [ 64] reported a decline in PIP1 and PIP2 transcript abundance in the roots of broccoli plants under increasing temperature, while Chen and Arora [ 65] highlighted the role of aquaporins (SoPIP2 1 and SoδTIP) during the recovery of spinach leaves from reversible freeze-thaw injury.
Seed growth from 25 to 30 DAA was characterized by a decline in the abundance of TaSUT2 transcripts.
NF-YA also regulates the expression of genes involved in the G1/S transition, and has been previously shown to exhibit a decline in protein levels without a change in transcript level with increasing senescence in IMR90 cells [ 41].
Both genes displayed a decline in expression as the seed coat matured, but PsLAR transcripts decreased significantly faster than PsANR transcript.
