Arrowheads in (B, D, F, H, J, and L) indicate the orientation of GFP-PIN1 localization, basal in procambial cells, and apical in protoderm.

Recent data show that ATHB8 expression is regulated directly by MP, is required for procambial cell specification, and its loss of function phenotype is masked by MP function

The HD-Zip transcription factor AtHB8 is a positive regulator of vascular cell differentiation; its promoter is active in cells prior to their adopting vascular procambial cell fate, as well as in developed strands

Vascular coordination is poor throughout the mutant seedling and originates from patterning problems at the point of procambial coordination.

E: hyd1 seedling (detail from d) showing lack of procambial and vascular strand coordination at the branch point in the upper hypocotyl; bar = 50 µm.

Here we show that the proAtHB8: GUS marker is very poorly localized in the hyd mutants, particularly in embryos where longitudinal procambial traces are established which define the plant body, and also in cotyledons and true leaves of establishment-stage seedlings.

These observations suggest that the patterning processes allowing the definition of the procambial strands have been disrupted in the

For visualization of procambial tissue in whole-mount embryos, developing siliques were harvested from plants heterozygous for hyd/fk mutations, and carrying the proAtHB8:: GUS transgene, the testa punctured with a fine tungsten histology needle, and the embryos vacuum-infiltrated with X-Gluc in buffer.

The monopteros mutant, for example, is expressed in the Arabidopsis embryo, and the mutant is characterized by abnormal divisions in the prospective procambial tissue in the embryo and defective cotyledonary vein formation
