Root Systems Biology [PDF]

open access: yesFrontiers in Plant Science, 2014
The understanding of biological complexity has been greatly facilitated by cross-disciplinary, holistic approaches that allow insights into the function and regulation of biological processes that cannot be captured by dissecting them into their individual components. In addition, the development of novel tools has dramatically increased our ability to

Root and Root Canal Morphology Classification Systems [PDF]

open access: yesInternational Journal of Dentistry, 2021
Introduction. While there are many root morphology classification systems with their own distinct advantages, there are many shortcomings that come along with each system. Objectives.

Completely Integrable Systems Associated with Classical Root Systems [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
We study integrals of completely integrable quantum systems associated with classical root systems. We review integrals of the systems invariant under the corresponding Weyl group and as their limits we construct enough integrals of the non-invariant ...

Spatio-Temporal Variation in Water Uptake in Seminal and Nodal Root Systems of Barley Plants Grown in Soil [PDF]

open access: yesFrontiers in Plant Science, 2020
The spatial and temporal dynamics of root water uptake in nodal and seminal roots are poorly understood, especially in relation to root system development and aging.

A Divided Difference Operator [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
We construct a divided difference operator using GKM theory. This generalizes the classical divided difference operator for the cohomology of the complete flag variety.

On a chain of reproducing kernel Cartan subalgebras

open access: yesMoroccan Journal of Pure and Applied Analysis, 2021
Let 𝔤 be a semisimple Lie algebra, j a Cartan subalgebra of 𝔤, j*, the dual of j, jv the bidual of j and B(., .) the restriction to j of the Killing form of 𝔤.

Optimizing Crop Water Use for Drought and Climate Change Adaptation Requires a Multi-Scale Approach

open access: yesFrontiers in Plant Science, 2022
Selection criteria that co-optimize water use efficiency and yield are needed to promote plant productivity in increasingly challenging and variable drought scenarios, particularly dryland cereals in the semi-arid tropics. Optimizing water use efficiency

High-Throughput in situ Root Image Segmentation Based on the Improved DeepLabv3+ Method

open access: yesFrontiers in Plant Science, 2020
The Rhizotrons method is an important means of detecting dynamic growth and development phenotypes of plant roots. However, the segmentation of root images is a critical obstacle restricting further development of this method.

The arithmetic Tutte polynomials of the classical root systems [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
Many combinatorial and topological invariants of a hyperplane arrangement can be computed in terms of its Tutte polynomial. Similarly, many invariants of a hypertoric arrangement can be computed in terms of its arithmetic Tutte polynomial. We compute the

Root Pulling Force Across Drought in Maize Reveals Genotype by Environment Interactions and Candidate Genes

open access: yesFrontiers in Plant Science, 2022
High-throughput, field-based characterization of root systems for hundreds of genotypes in thousands of plots is necessary for breeding and identifying loci underlying variation in root traits and their plasticity.
