Plant and soil 2007 v.301 no.1-2 pp. 37-49
ISSN:

Subject:
Taraxacum officinale; abscisic acid; biosynthesis; corn; field experimentation; habitats; tungsten; water stress
Abstract:
... The effect of tungsten as a potential inhibitor of ABA biosynthesis in plants was tested both under controlled conditions in the greenhouse or laboratory and in the field at a site naturally enriched with tungsten. Although as predicted in all cases the activity of aldehyde oxidase was strongly inhibited by tungsten, in well watered, greenhouse-grown maize plants increased concentrations of tungst ...

Subject:
Zea mays; biomass; biosynthesis; corn; drought; drought tolerance; ethyl methanesulfonate; flavonols; gene expression regulation; homeostasis; hydrogen peroxide; mutants; oxygen; photosynthesis; seedlings; soil water content; stomatal conductance; stomatal movement; temperature; transcriptome; transcriptomics; water stress; water use efficiency
Abstract:
... BACKGROUND AND AIMS: As drought threatens the yield and quality of maize (Zea mays L.), it is important to dissect the molecular basis of maize drought tolerance. Flavonoids, participate in the scavenging of oxygen free radicals and alleviate stress-induced oxidative damages. This study aims to dissect the function of flavonoids in the improvement of maize drought tolerance. METHODS: Using far-inf ...

biosynthesis; catalase; catechol oxidase; corn; gluconeogenesis; glycolysis; malondialdehyde; microirrigation; peroxidase; proline; root growth; root shoot ratio; soil water content; starch; sucrose; superoxide anion; superoxide dismutase; transcriptome; water uptake; water use efficiency
Abstract:
... AIMS: This study assessed the effect of stable soil water content on root growth and water use efficiency in maize under a negative pressure irrigation system. METHODS: A two-year pot experiment for maize was carried out under negative pressure irrigation and drip irrigation. The root growth characteristics and water use efficiency by the maize was evaluated. In addition, transcriptome sequencing ...

Subject:
aluminum; benzoxazinoids; biosynthesis; chelation; corn; cultivars; exudation; hydroxamic acids; root growth; root tips; salicylic acid
Abstract:
... BACKGROUND AND AIMS: Although aluminum (Al) exclusion via root exudation of organic matters is a common resistance mechanism adopted by many plant species, whether root exudation of benzoxazinoids, such as hydroxamic acids (HAs), confers Al resistance remains unclear. METHODS: We performed physiological characterization for an Al-resistant maize cultivar TY and a sensitive maize cultivar ZD. RESUL ...
