Journal ArticleDOI
Topsoil foraging – an architectural adaptation of plants to low phosphorus availability
TL;DR: 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.
Journal ArticleDOI
Shovelomics: high throughput phenotyping of maize ( Zea mays L.) root architecture in the field
TL;DR: 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.
Journal ArticleDOI
Root architectural tradeoffs for water and phosphorus acquisition
TL;DR: The hypothesis that root architectural tradeoffs exist for multiple resource acquisition, particularly when resources are differentially localised in the soil profile, is supported.
Journal ArticleDOI
Regulation of root hair density by phosphorus availability in Arabidopsis thaliana
TL;DR: 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.
Journal ArticleDOI
Ethylene and abscission
TL;DR: 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.
