“…The enzyme S-adenosylmethionine decarboxylase (AdoMetDC) decarboxylates adenosylmethionine (AdoMet) to produce dcAdoMet. CPuORF-mediated translational control of AdoMetDC has been well documented in different systems (Ivanov et al, 2010; Uchiyama-Kadokura et al, 2014) and was recently reviewed in detail (Poidevin et al, 2019).…”

“…NMD allows the plant to identify and destroy mRNAs that would otherwise give rise to partial proteins, which may possess maladaptive activities. The NMD mechanism requires three Upf proteins (UPF1 to UPF3), SMG1 and SMG7, and a helicase distantly related to eIF4A, eIF4A III (Ohtani & Wachter, 2019; Poidevin, Unal, Belda‐Palazon, & Ferrando, 2019). NMD is further stimulated by other accessory proteins such as the helicase DDX6 (RH12) (Sulkowska et al, 2019).…”

Translational gene regulation in plants: A green new deal

The molecular machinery for protein synthesis is profoundly similar between plants and other eukaryotes. Mechanisms of translational gene regulation are embedded into the broader network of RNA-level processes including RNA quality control and RNA turnover. However, over eons of their separate history, plants acquired new components, dropped others, and generally evolved an alternate way of making the parts list of protein synthesis work. Research over the past 5 years has unveiled how plants utilize translational control to defend themselves against viruses, regulate translation in response to metabolites, and reversibly adjust translation to a wide variety of environmental parameters. Moreover, during seed and pollen development plants make use of RNA granules and other translational controls to underpin developmental transitions between quiescent and metabolically active stages. The economics of resource allocation over the daily light-dark cycle also include controls over cellular protein synthesis. Important new insights into translational control on cytosolic ribosomes continue to emerge from studies of translational control mechanisms in viruses. Finally, sketches of coherent signaling pathways that connect external stimuli with a translational response are emerging, anchored in part around TOR and GCN2 kinase signaling networks. These again reveal some mechanisms that are familiar and others that are different from other eukaryotes, motivating deeper studies on translational control in plants.

“…Moreover, PAs reprogramming oxidative and nitrosative status of salt exposed citrus plants could affect their redox status (Tanou et al, 2014). Newest findings suggest that PAs can adjust the quality control of post-transcriptional regulation (Poidevin et al, 2019). Some important N-containing metabolite like proline amino acid (Szepesi and Szollosi, 2018;Guan et al, 2020) or gamma-aminobutyric acid (GABA) as endproduct of PA catabolism could be involved in abiotic stress responses (Su et al, 2019).…”

Halotropism is a sodium specific tropic movement of roots in order to obtain the optimal salt concentration for proper growth and development. Numerous results suggest that halotropic events are under the control and regulation of complex plant hormone pathway. This minireview collects some recent evidences about sodium sensing during halotropism and the hormonal regulation of halotropic responses in glycophytes. The precise hormonal mechanisms by which halophytes plant roots perceive salt stress and translate this perception into adaptive, directional growth forward increased salt concentrations are not well understood. This minireview aims to gather recently deciphered information about halotropism focusing potential hormonal aspects both in glycophytes and halophytes. Advances in our understanding of halotropic responses in different plant species could help these plants to be used for sustainable agriculture and other future applications.
