Regulation of root hair density by phosphorus availability in Arabidopsis thaliana
We characterized the response of root hair density to phosphorus (P) availability in Arabidopsis thaliana. Arabidopsis plants were grown aseptically in growth media with varied phosphorusExpand

Shovelomics: high throughput phenotyping of maize (Zea mays L.) root architecture in the field
We present a method to visually score 10 root architectural traits of the root crown of an adult maize plant in the field in a few minutes. Phenotypic profiling of three recombinant inbred line (RIL)Expand

Topsoil foraging – an architectural adaptation of plants to low phosphorus availability
Low phosphorus availability is a primary constraint to plant productivity in many natural and agricultural ecosystems. Plants display a wide array of adaptive responses to low phosphorus availabilityExpand

Ethylene and abscission
A substantial body of literature supports the involvement of ethylene in abscission of leaves, flowers and flower parts, and fruit. Exogenous ethylene accelerates abscission in many, but not all,Expand

Regulation of Root Elongation under Phosphorus Stress Involves Changes in Ethylene Responsiveness1
We characterized the growth of the primary root of Arabidopsis under phosphorus sufficiency (1 mm phosphate) and deficiency (1 μm phosphate), focusing on the role of ethylene. We quantified theExpand

Ethylene and phosphorus availability have interacting yet distinct effects on root hair development.
The hypothesis that ethylene participates in the regulation of root hair development by phosphorus availability in Arabidopsis thaliana was tested by chemically manipulating ethylene synthesis andExpand

Ethylene: a regulator of root architectural responses to soil phosphorus availability
The involvement of ethylene in root architectural responses to phosphorus availability was investigated in common bean (Phaseolus vulgaris L.) plants grown with sufficient and deficient phosphorus.Expand

Root architectural tradeoffs for water and phosphorus acquisition.
Root architectural traits that increase topsoil foraging are advantageous for phosphorus acquisition but may incur tradeoffs for the acquisition of deep soil resources such as water. To examine thisExpand

Root cortical aerenchyma improves the drought tolerance of maize (Zea mays L.).
Root cortical aerenchyma (RCA) reduces root respiration in maize by converting living cortical tissue to air volume. We hypothesized that RCA increases drought tolerance by reducing root metabolicExpand
