Abstract
Vascular plants have a network of vasculature in their leaves which supplies water and nutrients and exports photoassimilates to other tissues The vascular network is patterned during the development of leaf primordia through the induction of provascular differentiation by auxin Arabidopsis thaliana Dof58 encoding a Doftype transcription factor is expressed early in provascular cells under the control of the MONOPTEROS transcription factor also known as auxin response factor 5 ARF5 Here we report the effect of overexpressing Dof58 in provascular cells on the formation of the vascular network Overexpression of Dof58 inhibited the formation of higherorder veins in cotyledons and leaves probably through transcriptional repression by Dof58 The expression of auxinassociated transcription factor genes DORNRöSCHEN and SHIRELATED SEQUENCE 5 was downregulated in the Dof58 overexpressors and overexpression of these genes partially rescued the impaired formation of higherorder veins in Dof58overexpressing lines suggesting that the overexpression of Dof58 modulates the auxin response and leads to impaired vein formation in A thaliana
