Abscisic acid: interactions with ethylene and reactive oxygen species in the regulation of root growth under water deficit
(University of Missouri--Columbia, 2011)Abscisic acid (ABA) is involved in several responses to plant water deficits, including an important role in root growth maintenance. Studies of the ABA-deficient maize mutant viviparous 14 (vp14) showed that ABA-deficiency ... -
Function of abscisic acid in maintenance of maize primary root growth under water deficit
(University of Missouri--Columbia, 2006)Previous studies suggested that ABA accumulation is required to maintain maize primary root elongation under water deficit and that one of the functions of ABA is to restrict ethylene evolution. These studies were conducted ... -
A genotypic comparison of plasticity of root system development during soil drying in soybean (Glycine max (L.) merrill)
(University of Missouri--Columbia, 2006)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Water deficit is responsible for significant losses in soybean (Glycine max (L.) Merrill) yield under dryland conditions. Under drought, increases in ... -
Plasticity of soybean (Glycine max (l.) Merrill) root system development under mild water deficit
(University of Missouri--Columbia, 2008)Drought is the major abiotic factor limiting soybean yield in the US. Under water deficit conditions, root systems may exhibit developmental plasticity resulting in morphological changes that extend the water-absorbing ... -
Role of oxalate oxidase and apoplastic reactive oxygen species in root growth regulation in water-stressed maize primary roots
(University of Missouri--Columbia, 2012)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Previous work on maize primary roots under water stress showed that cell elongation is maintained in the apical region of the growth zone but progressively ...
