“…It appears that cAMP-dependent signaling may be closely linked to cytosolic Ca 2+ as well as Na + and K + fluxes [20][21][22]. At the system level, rapid and reversible post-translational modification by phosphorylation is essential for plant development and adaptation to changing environmental conditions [23]. In mammals, increases in cAMP levels promote the phosphorylation of several intracellular enzymes via the activation of protein kinase A (PKA) [24].…”

3′,5′-cyclic adenosine monophosphate (cAMP) is finally recognized as an essential signaling molecule in plants where cAMP-dependent processes include responses to hormones and environmental stimuli. To better understand the role of 3′,5′-cAMP at the systems level, we have undertaken a phosphoproteomic analysis to elucidate the cAMP-dependent response of tobacco BY-2 cells. These cells overexpress a molecular "sponge" that buffers free intracellular cAMP level. The results show that, firstly, in vivo cAMP dampening profoundly affects the plant kinome and notably mitogen-activated protein kinases, receptor-like kinases, and calcium-dependent protein kinases, thereby modulating the cellular responses at the systems level. Secondly, buffering cAMP levels also affects mRNA processing through the modulation of the phosphorylation status of several RNA-binding proteins with roles in splicing, including many serine and arginine-rich proteins. Thirdly, cAMP-dependent phosphorylation targets appear to be conserved among plant species. Taken together, these findings are consistent with an ancient role of cAMP in mRNA processing and cellular programming and suggest that unperturbed cellular cAMP levels are essential for cellular homeostasis and signaling in plant cells.

“…While these terms are not as directly-related to physiological differences as the upregulated categories, fast growth is the most distinguishing factor of eastern versus western seed sources. The genetic mechanisms of how plants can achieve fast growth is complex; however, sterol biosynthetic processes and protein phosphorylation are known to be involved in plant growth and regulation (Schaller 2003, Li andLiu 2021).…”

The selection of an appropriate seed source for a given geographic region is critical to ensuring prosperous southern pine plantations. The observed variation between eastern and western loblolly pine seed sources has shown differences in economically advantageous traits such as drought tolerance, growth rates, and disease resistance. Understanding what drives these local adaptations is of interest, given that current forecasted climate modeling suggests there will be increased temperatures and changes to precipitation by the year 2050. The objectives of this experiment were to 1) identify differentially expressed transcripts between eastern and western loblolly pine sources; 2) link these transcripts to Arabidopsis orthologs; 3) compare GO categories of differentially-expressed transcripts. The findings highlighted include interesting pathways and genes that are related to the known differences among eastern and western seed provenances. Additionally, they represent fundamental differences in the beginning of seedling development without any treatment or disease pressure applied, showing that there are detectable differences between these two provenances at a young age. Overall, this experiment contributes to the body of literature on fundamental differences between loblolly pine seed sources.

“…Nearly half of expressed Arabidopsis proteins have been found to be phosphorylated. [71,72] Protein kinases predominantly catalyze a phosphoryl group transfer from ATP to the hydroxyl groups of specific serine (Ser, S), threonine (Thr, T), or tyrosine (Tyr, R) residues within target proteins. [70] Multiple kinases and phosphatases are essential for the phosphorylation-based regulation of auxin processes.…”

Auxin is a key regulator of plant developmental processes. Its effects on transcription are mediated by the AUXIN RESPONSE FACTOR (ARF) family of transcription factors. ARFs tightly control specific auxin responses necessary for proper plant growth and development. Recent research has revealed that regulated ARF protein accumulation and ARF nucleo‐cytoplasmic partitioning can determine auxin transcriptional outputs. In this review, we explore these recent findings and consider the potential for regulated ARF accumulation in driving auxin responses in plants.
