Fig. 1. The core energy management machinery, comprising SnRKs, TORC, and the T6P pathway, and its interactions with multiple signals through complex feedback regulation to regulate growth and resilience trade-offs.
The cover depicts a whiteboard illustration of the original concept behind the workshop ‘Plant Energy Management: Molecular Mechanisms and Signalling,’ held at UPSC, Sweden, in August 2024. The aim was to expand upon the original TOR meeting by focusing on the inputs and outputs of the core energy management machinery in a species-agnostic manner.

Great preprint by Liu, Blanford et al. (2025) on how trehalose 6-phosphate #T6P stimulates plant cell growth via #PlantTOR and is required for sucrose-induced TOR activation in #Arabidopsis by suppressing #SnRK1 in a dose-dependent manner, thereby mediating the antagonistic TOR–SnRK1 relationship.
Great #preprint by Chen et al. (2025) on revealing the role of #SalicylicAcid (SA) in controlling central metabolic regulators #SnRK1 and #PlantTOR to coordinate plant immunity and growth by differential phosphorylation of #Arabidopsis NPR1, a key SA receptor (Ser-557 and Ser-55/59, respectively)🤯.
#ATSPB2025 conference organised by @bokuvienna.bsky.social happy to present progress of #roots phenotyping @barleymicrobreed.bsky.social and tracking elongation dynamics of #seedlingestablishment #roothairs #apicalhook #snrk1 #kin10
In HR, the study, titled "NpCIPK6–NpSnRK1 module facilitates intersubgeneric hybridization barriers in water lily by reducing abscisic acid content," reveals a novel molecular mechanism underlying cross-subgenus incompatibility in water lilies.

Details: doi.org/10.1093/hr/u...
aligning with previous studies we support that #KIN10 #Snrk1 differentially regulate root and shoot responses to biotic stress, with its absence leading to impaired root development and reduced pathogen sensitivity, while its overexpression enhances shoot immune responses at the cost of growth

Figure 6. Cytochrome c (CYTc) deficiency affects TOR pathway activity, downstream of SnRK1. (A) Western blot analysis of RPS6 phosphorylation in WT plants, cytc-1a and akin10-2 single mutants, and cytc-1a akin10-2 double mutants using anti-P-RPS6 antibodies. Extracts were prepared from seedlings grown for 3.5 days in 0.59 MS medium, followed by an extended night (16 h) for nutrient depletion and treatment with 20 mM glucose for 3 h to activate TOR (Xiong et al., 2013). Anti-RPS6 antibodies were used as a control of total RPS6 levels. Anti-Actin antibodies were used for the control of loading. The original uncropped image is shown in Figure S8. On the right, a quantification of P-RPS6 and total RPS6 band intensities relative to WT plants after normalisation with actin is shown. Different letters indicate significant differences (three independent experiments; P < 0.05; ANOVA). (B) Hypocotyl growth in WT plants, cytc-1a and akin10-2 single mutants, and cytc-1a akin10-2 double mutants grown as in (A) and supplemented with different concentrations of selective TOR inhibitor AZD-8055. Hypocotyl length was measured using ImageJ software. Asterisks indicate significant differences with WT (n = 20; P < 0.05; ANOVA). (C) Representative images of the experiment shown in (B). Bar: 0.5 cm.
Figure 6D. Model of the connection between cytochrome c (CYTc) levels and plant growth and stress responses. Under normal conditions (left), CYTc, probably acting as an OXPHOS component, exerts repression on SnRK1 activity, thus allowing TOR activation and plant growth. A decrease in CYTc levels (right) derepresses SnRK1, leading to growth inhibition and the activation of autophagy and stress responses. Since stress conditions affect mitochondrial function, it can be envisaged that CYTc dependent processes are part of a signal that influences the balance between growth and stress responses through SnRK1.
Great work by Coronel et al. (2024) on how altering cytochrome c (CYTc) levels affected #SnRK1 activity in #Arabidopsis 🌱, indicating a molecular link between #mitochondrial function and #PlantTOR -mediated growth under normal and mannitol stress conditions.
