Exploring relationships between root architecture and growth of UK wheats (Triticum aestivum L.)
… during the grain filling period, growing deep rooting cultivars increased wheat yields by approximately 15%. Seedling root angle is associated with adult root system depth in Australian field-grown wheat cultivars (Triticum aestivum L.), but it is not yet known whether selection for root angle …

Evaluation of Barley (Hordeum vulgare L.) Stem and Root Traits that Influence Lodging
… within a set of field-based plant, stem and root mechanical and architectural traits that were well correlated to lodging, and 2) to identify and evaluate traits within a set of lab-based root architecture traits that were well correlated to lodging. To address the first objective, 13 spring …

Plant root development and hormone signalling during drought stress
The plant root system is crucial for plant survival, growth and development, and it plays an important role in plant resistance to drought stress. Drought is one of the primary factors that restrict plant growth and yield, and its threat to crop yields will increase along with the growing food …

Unlocking the genetic potential of the root system, rhizosheath mucilage and microbiome of wheat (Triticum aestivum L.)
… of latitudes across both hemispheres. The wheat root system is a crucial determinant of plant performance, yet roots are overlooked in breeding due to the challenge of studying organs below ground. Evidence from the literature indicate that water and nutrient uptake are often suboptimal in high …

Protein Phosphatase 2A Function in Response to Salt Stress in Arabidopsis thaliana: Defining Pathways and Genetic Interaction Networks
… subset of the A and C subunit mutants exhibited root skewing or curling phenotypes when grown on vertically-oriented plates supplemented NaCl. I characterized the root response of a1rcn1 and c4 mutants and found that the root phenotype was sodium specific and influenced by NaCl concentration, …

Evaluation of phenotyping methods for maize
… been developed that allow for the measurement of root complexity, stalk diameter and root angle. The method used is direct imaging of the root structures under controlled diffuse lighting. The method as developed in this work, differs in that the lighting is not diffuse, but structured in the form …

High-throughput maize root phenotyping
The root system is important for plant adaptability to changing environments. Although the importance of the root system is well reported in the research literature there is still a considerable lack of knowledge with regard to the development of root systems per se, and how root system complexity …

Mechanical and metallurgical properties of dissimilar metal joints using novel joining techniques
… with a negative gradient to value of the root angle on the mild steel side of the joints, as the angle at the root decreases the fatigue life increases. It was found that when joining the material combinations outlined in this research with Laser Hybrid Welding the resulting solidified …

Above and below ground phenotyping methods for corn
… be used to predict the PPY, the below ground root system is indicative of iii the plants’ stability, and of its ability to reach nutrients and water. A “Rhizotron” was constructed, which consists of a soil volume, visible behind a vertical glass pane. By growing a single corn plant in the …

Sviluppo e validazione di metodologie di miglioramento genetico dell'orzo basate sulla predizione genomica per sostenere l'innovazione varietale e l'agricoltura del futuro.
Il miglioramento genetico delle piante coltivate, iniziato circa 10.000 anni fa, è basato su un complesso processo di selezione della variabilità genetica al fine di creare nuove varietà più produttive, resistenti a malattie, capaci di adattarsi a condizioni climatiche sfavorevoli ed in …
