Abstract
Toward the understanding the mechanisms of formation of leaf-venation pattern, we have isolated and analyzed Arabidopsis mutants defective in formation of leaf veins. no vein-1 mutant (nov-1) often produces leaves without veins. Expression patterns of ATHB8 and DR5 in nov-1 suggest that NO VEIN gene (NOV) is necessary for prepro/procambial cell formation and for proper auxin accumulation pattern that is prerequisite for vascular development in leaves. NOV encodes a protein with unknown function. Null alleles of nov-2~5 mutants exhibit embryo-defective phenotype. The phenotype of nov mutants and expression pattern of ATHB8 and DR5 in nov mutants will be presented.
