General information

Mutant name abi2-1/hlq
Mutant/Transgenic plant mutant
Ecotype Ler

PMID 12008902
CommentThe harlequin mutant was isolates based on the phenotype of a distinct checkered pattern of ectopic,strong Dc3-GUS expression in the hypocotyl, root epidermis, and zones of elongation and maturation in the absence of ABA inductive treatment.
