Cell density and airspace patterning in the leaf can be manipulated to increase leaf photosynthetic capacity (2017)
Journal Article

The pattern of cell division, growth and separation during leaf development determines the pattern and volume of airspace in a leaf. The resulting balance of cellular material and airspace is expected to significantly influence the primary function o...

Shaping 3D root system architecture (2017)
Journal Article

Plants are sessile organisms rooted in one place. The soil resources that plants require are often distributed in a highly heterogeneous pattern. To aid foraging, plants have evolved roots whose growth and development are highly responsive to soil si... Read More about Shaping 3D root system architecture.

Quantification of seed-soil contact of sugar beet (Beta vulgaris) using X-ray Computed Tomography (2017)
Journal Article

© 2017 The Author(s). Background: Seed-soil contact is important to ensure successful germination, however, there is a paucity of reported studies that have quantified the microstructure at and around this critical interface, mainly due to the opacit...

Quantification of differences in germination behaviour of pelleted and coated sugar beet seeds using X-ray Computed Tomography (X-ray CT) (2017)
Journal Article

Seed enhancement technologies i.e. priming, pelleting and coating have been extensively9 used throughout the last century to improve crop yield and to reduce losses associated with pest infestation. However, until recently, it has not been possible t...

Root morphology and biomechanical characteristics of high altitude alpine plant species and their potential application in soil stabilization (2017)
Journal Article

Glacial forefields host young, poorly developed soils with highly unstable environmental conditions. Root system contribution to soil stabilization is a well-known phenomenon. Identifying the functional traits and root morphology of pioneer vegetatio...

Root hydrotropism is controlled via a cortex-specific growth mechanism (2017)
Journal Article

Plants can acclimate by using tropisms to link the direction of growth to environmental conditions. Hydrotropism allows roots to forage for water, a process known to depend on abscisic acid (ABA) but whose molecular and cellular basis remains unclear...
