Intercellular Concentration Gradients of 3-Phosphoglycerate and Triose-Phosphate Demonstrate Operation of an Energy Shuttle in NAD-Malic Enzyme and Phosphoenolypyruvate Carboxykinase C4 Subtypes

The paper demonstrates that NAD-ME and PEPCK C4 plant subtypes use an intercellular energy shuttle involving 3-phosphoglycerate and triose phosphate gradients between bundle sheath and mesophyll cells.

C4 photosynthetic pathway fluxes in transgenic rice plants

This study demonstrates that four core C4 pathway reactions are operating in transgenic rice, establishing in vivo flux for a functional carbon-concentrating mechanism.

Transient uncoupling of the Suc-Tre6P-SnRK1 nexus during salt stress associates with biphasic metabolic reprogramming and root plasticity

This study shows that salt stress in alfalfa causes a two-phase metabolic response involving transient disruption of the Suc-Tre6P-SnRK1 pathway, leading to root plasticity.

Exploring the diversity of the CO2-concentrating mechanism (CCM) in different C4 subtypes

The paper investigates C4 pathway fluxes in three C4 grass subtypes using 13CO2 pulse-chase experiments, revealing that both malate and aspartate contribute to the C4 cycle in all subtypes.

TPS Proteins coordinate plant growth with sugar availability via the SnRK1 Kinase

This study identifies TPS5/6/7 as T6P sensors that inhibit SnRK1 activity to coordinate plant growth with sugar availability in Arabidopsis thaliana.

Overcoming extensive redundancy in the arabidopsis TREHALOSE-6-PHOSPHATE PHOSPHATASE gene family reveals connections to development

The paper investigates the role of Arabidopsis TPP genes, showing they redundantly regulate shoot architecture, sugar metabolism, iron homeostasis, and photosynthesis through Tre6P signaling.

Intercellular compartmentation of trehalose 6-phosphate metabolism in Setaria viridis leaves

This study identifies that trehalose 6-phosphate is mainly synthesized and localized in bundle sheath cells of Setaria viridis leaves.

Seasonal changes in the physiology and metabolism of grapevine perennating buds

This study examines seasonal changes in grapevine perennating buds, identifying three phases of dormancy and their metabolic and physiological characteristics.

Too much sugar makes plants "pregnant": maternal sucrose signals fertilization in Arabidopsis seeds

The paper shows that sucrose triggers a fertilization-independent response in Arabidopsis maternal tissues, initiating seed development through hormonal and sugar signaling.

Wave-like SnRK1 Activation and Tre6P-Sucrose Imbalance Shape Early Salt Stress Response in Growing Alfalfa Leaves

This study shows that wave-like SnRK1 activation and Tre6P-sucrose imbalance occur early in alfalfa's salt stress response, linking metabolic shifts to growth inhibition.

The stress-protectant molecule trehalose mediates fluconazole tolerance in Candida glabrata

This study identifies trehalose as a mediator of fluconazole tolerance in C. glabrata by altering sterol composition, showing that trehalose deficiency reduces drug tolerance.

Spliceosomal complex components are critical for adjusting the C:N balance during high-light acclimation

The paper identifies spliceosomal components critical for adjusting carbon:nitrogen balance and anthocyanin accumulation during high-light acclimation in Arabidopsis.
