Direct and indirect responses of the Arabidopsis transcriptome to an induced increase in trehalose 6-phosphate

An induced increase in trehalose 6-phosphate levels affects gene expression directly by inhibiting SnRK1 and indirectly through changes in sucrose levels, impacting growth, metabolism, and signaling pathways.

Diel fluctuations in in-vivo SnRK1 activity in Arabidopsis rosettes during light-dark cycles

The paper measures in-vivo SnRK1 activity in Arabidopsis during light-dark cycles and finds it peaks at night and is influenced by metabolic regulators like Tre6P and glucose 6-phosphate.

Operation of Carbon-Concentrating Mechanisms in Cyanobacteria and Algae requires altered poising of the Calvin-Benson cycle

The paper compares Calvin-Benson cycle metabolite profiles in cyanobacteria and algae with terrestrial plants, finding distinct patterns suggesting the operation of carbon-concentrating mechanisms.

The pathway of starch synthesis in Arabidopsis thaliana leaves

The paper resolves a 20-year controversy by showing that ADPG pyrophosphorylase in chloroplasts, not sucrose synthase in the cytosol, is the primary source of ADPG for starch synthesis in Arabidopsis leaves.

The role of trehalose 6-phosphate in shoot branching - local and non-local effects on axillary bud outgrowth in arabidopsis rosettes

This study investigates the role of Tre6P in shoot branching by manipulating its levels in axillary buds and vascular tissues, showing both local and systemic effects on branching via FT.

A partial C4 photosynthetic biochemical pathway in rice

This paper introduces a partial C4 photosynthetic pathway in rice by expressing four C4 enzymes, showing increased 13C incorporation into malate and aspartate but limited flux into the Calvin-Benson cycle.

Overexpression of sedoheptulose-1,7-bisphosphatase enhances photosynthesis in Chlamydomonas reinhardtii and has no effect on the abundance of other Calvin-Benson cycle enzymes

This study overexpresses sedoheptulose-1,7-bisphosphatase in Chlamydomonas reinhardtii, increasing photosynthesis and growth without affecting other Calvin-Benson cycle enzymes.

Phytochrome light receptors control metabolic flux, and their action during seedling development sets the trajectory for biomass production

This study shows that phytochromes regulate metabolic flux and biomass production by controlling glucose-starch balance and carbon allocation during seedling development.

Kingdom-wide comparison reveals conserved diurnal gene expression in Archaeplastida

The paper compares diurnal gene expression across nine Archaeplastida species, finding conserved transcriptional programs despite evolutionary divergence and lifestyle differences.

Photoperiodic control of the Arabidopsis proteome reveals a translational coincidence mechanism

The paper quantifies the Arabidopsis proteome across photoperiods, identifies translational coincidence as a mechanism for photoperiodic protein regulation, and shows its conservation in other phototrophic organisms.
