Zea Lip: An atlas of glycerolipid profiles across leaf development in maize

UHPLC-MS/MS lipidomics of maize leaves (149 species, three genotypes, four growth stages, three leaf zones) shows genotype and leaf number explain most lipid variation.

Intraspecific variability rivals interspecific differences in root traits of temperate tree seedlings

This study quantifies intraspecific and interspecific variation in root traits of tree seedlings and finds that intraspecific variability often exceeds interspecific differences, highlighting the importance of plasticity in root traits for regeneration under climate change.

Salt stress shifts wild tomato root systems toward transport efficiency along a gravitropism-constrained Pareto front

The paper models how salt stress alters root system architecture in wild tomatoes by incorporating lateral-root curvature and identifies a heritable genetic locus associated with transport efficiency.

Phenological stage influences how white lupin (Lupinus albus) root exudate metabolites respond to phosphorus supply

This study shows that phenological stage has a stronger effect on root exudate metabolites in white lupin than phosphorus supply, with phosphorus effects only observed during flowering.

Root anatomical gradients and cultivar differences underlie variation in root hydraulic properties in German winter wheat

This study links root anatomical gradients and cultivar differences to variations in hydraulic properties in winter wheat using imaging and modeling.

Phosphorus limitation enhances root exudation and mineral bioweathering across diverse soil process domains

This study shows that phosphorus limitation increases root exudation of carboxylates, which enhances mineral dissolution across different soil types.

Secondary Growth and Exodermal Barriers Shape Local Root Hydraulics: Modeling Insights in Tomato

The paper models how secondary growth and exodermal barriers affect root hydraulics in tomato, showing exodermal suberin has little effect with a lignin cap and secondary growth is crucial for maintaining axial conductance.

MultiSpecies Canopy Segmentation: Interactive Machine-Learning and Pseudo-Labelling are key

This paper develops a method to train deep-learning models for multi-species canopy segmentation using FCNNs and pseudo-labeling, achieving high accuracy with reduced human effort.

The Rapid Anatomics Tool (RAT): A low-cost root anatomical phenotyping pipeline reveals changes in root anatomy along the root axis

The paper introduces RAT, a low-cost root anatomical imaging system, and shows reduced vascular complexity in wheat crown roots from basal to distal regions.

Root System Architecture Reorganization Under Decreasing Soil Phosphorus Lowers Root System Conductance of Zea mays

This study examines how decreasing phosphorus availability affects root system architecture and conductance in Zea mays, showing reduced conductance with lower phosphorus levels.

The evolution of root hydraulic traits in wheat over 100 years of breeding

This study examines how 100 years of wheat breeding affected root hydraulic traits, finding a decline in root number and hydraulic conductance while root diameter remained stable.

Novel multiscale insights into the composite nature of water transport in roots

The paper introduces MECHA, a mathematical model that predicts root radial permeability by integrating cell-level hydraulic properties and anatomical data from Zea mays roots.
