Contributions of lignification, tissue arrangement patterns, and cross-sectional area to whole-stem mechanical properties in Arabidopsis thaliana
Plant cells withstand mechanical stress originating from turgor pressure by robustly maintaining the mechanical properties of the cell wall. This applies at the organ scale as well; many plant stems act as pre...

Open AccessThe phosphorylated pathway of serine biosynthesis affects sperm, embryo, and sporophyte development, and metabolism in Marchantia polymorpha
Serine metabolism is involved in various biological processes. Here we investigate primary functions of the phosphorylated pathway of serine biosynthesis in a non-vascular plant Marchantia polymorpha by analyzing...

Open AccessPyrophosphate inhibits gluconeogenesis by restricting UDP-glucose formation in vivo
Pyrophosphate (PPi) is produced by anabolic reactions and serves as an energy donor in the cytosol of plant cells; however, its accumulation to toxic levels disrupts several common biosynthetic pathways and is...

Genetic variation in ZmVPP1 contributes to drought tolerance in maize seedlings
Feng Qin and colleagues perform a genome-wide association study for drought tolerance in maize seedlings and find 42 candidate genes. They characterize a promoter insertion in the ZmVPP1 gene containing MYB-bindi...

Regulation of PPi Levels Through the Vacuolar Membrane H+-Pyrophosphatase
Inorganic pyrophosphate (PPi) is a high-energy compound, although the free energy change of its hydrolysis is approximately 60 % that of ATP. PPi is generated as a by-product of macromolecule biosyntheses in p...

Control of Leaf Morphogenesis by Long- and Short-Distance Signaling: Differentiation of Leaves Into Sun or Shade Types and Compensated Cell Enlargement
The flattened, thin lamina of leaves captures sunlight for photosynthesis and facilitates gas exchange. Therefore, the size and shape of a leaf are fundamentally important features of its integrity and fun...

Coordination of cell proliferation and cell expansion in the control of leaf size in Arabidopsis thaliana
Size is an important parameter in the characterization of organ morphology and function. To understand the mechanisms that control leaf size, we previously isolated a number of Arabidopsis thaliana mutants with a...
