Involvement of microRNA-related regulatory pathways in glucose-mediated control of Arabidopsis early seedling development

ABSTRACT: In plants, sugars such as glucose act as signaling molecules that promote changes in gene expression programs impacting on growth and development. Recent evidences have revealed the potential participation of mRNA decay control in some aspects of glucose-mediated regulatory responses suggesting a role of microRNAs (miRNAs) in these responses. In order to get a better understanding of glucose-mediated development modulation involving miRNA-related regulatory pathways, early seedling development of mutants impaired in miRNA biogenesis (hyl1-2) and miRNA-activity (ago1-25) were evaluated. Both mutants exhibited a glucose hyposensitive phenotype from germination up to seedling establishment, indicating that miRNA regulatory pathways may be involved in the glucose-mediated delay of early seedl
