Regulation of root hair density by phosphorus availability in Arabidopsis thaliana
TLDR
The results show that phosphorus availability can fundamentally alter root anatomy, leading to changes in root hair density, which are presumably important for phosphorus acquisition.
Topsoil foraging – an architectural adaptation of plants to low phosphorus availability
TLDR
Comparisons of contrasting genotypes in controlled environments and in the field show that plants with better topsoil foraging have superior phosphorus acquisition and growth in low phosphorus soils, and it appears that many architectural responses to phosphorus stress may be mediated by the plant hormone ethylene.
Shovelomics: high throughput phenotyping of maize (Zea mays L.) root architecture in the field
TLDR
The method to visually score 10 root architectural traits of the root crown of an adult maize plant in the field in a few minutes underscores the suitability of the method to evaluate genotypes across environments.
Ethylene and abscission
TLDR
A substantial body of literature supports the involvement of ethylene in abscission of leaves, flowers and flower parts, and fruit, and endogenous ethylene production increases before abscissions, while in others a change in ethylene sensitivity can be demonstrated.
Ethylene: a regulator of root architectural responses to soil phosphorus availability
TLDR
Enhanced ethylene production and altered ethylene sensitivity in phosphorus-deficient plants may be responsible for root responses to phosphorus deficiency.
Regulation of Root Elongation under Phosphorus Stress Involves Changes in Ethylene Responsiveness1
TLDR
The root system acclimates to phosphorus deficiency by changing the signal transduction pathway connecting ethylene levels to growth and division, which regulates the maximal rate of relative elongation rather than the size of the growth zone.
Ethylene and phosphorus availability have interacting yet distinct effects on root hair development.
TLDR
Multiple effects of low phosphorus from the earliest stages of root hair development, and cross-talk between ethylene and phosphorus in the control of a subset of the low phosphorus effects, concentrating on those later in development are demonstrated.
Root architectural tradeoffs for water and phosphorus acquisition.
TLDR
The hypothesis that root architectural tradeoffs exist for multiple resource acquisition, particularly when resources are differentially localised in the soil profile, is supported.
A Novel Image-Analysis Technique for Kinematic Study of Growth and Curvature1[W][OA]
TLDR
KineRoot is capable of analyzing a large number of images to generate local root growth and root curvature data over several hours, permitting kinematic analysis of growth and gravitropic responses for a variety of root types.

TLDR
It is proposed that a better understanding of the root phenome is needed to effectively translate genetic advances into improved crop cultivars and to develop methods to measure phene expression rapidly and economically without artefacts.
