Transcriptome analysis of differentially expressed genes in the harlequin (hlq) mutant

ABSTRACT: Plant growth and development is continuous and modular, a combination that allows morphogenesis by controlled cell division and elongation and serves to facilitate plantsM-bM-^@M-^Y adaptations to changing environments. Plasticity is achieved through integration of external and internal signals to regulate meristem activities. We previously characterized the pleiotropic phenotypes of the harlequin (hlq) mutant, isolated on the basis of ectopic expression of ABA- and auxin-inducible proDc3:GUS in roots and hypocotyls. Mutants are skotomorphogenic (dark development of true leaves and chlorophyll accumulation), have deformed and collapsed epidermal cells that accumulate callose and starch and stain strongly with the vital dye fluorescein diacetate, brittle stems and leaves, cell walls with
