Dual Roles of Heterotrophic Ammonia-Oxidizing Bacteria in Enhancing Compensatory Growth upon Post-Drought in Maize.

This study investigates the mechanisms driving maize compensatory growth upon post-drought, to reveal how the root's original cytokinins are regulated by the two-fold roles of heterotrophic bacteria with ammonia-oxidizing (HAOB) capabilities. The HAOB' dual roles encompass influencing root cytokinin synthesis and transport through nitrification and a direct pathway. Experiment 1 involved introducing the application of varying amounts of NO to the roots to examine how nitrification affects cytokinin roots-to-leaves transport.

Selection of Reference Genes for Real-time Quantitative PCR Normalization in the Process of var. Infecting Wheat.

var. is a soil borne pathogenic fungus associated with wheat roots. The accurate quantification of gene expression during the process of infection might be helpful to understand the pathogenic molecular mechanism.
