Abstract excerpt
Phytochrome-interacting factors (PIFs) have been established as negative regulators of vascular patterning and xylem differentiation in the herbaceous plant Arabidopsis thaliana, however, the regulatory role of PIFs in secondary growth in woody species remains unclear. Here, we examines the expression patterns and involvement of PtoPIF3.1 and PtoPIF3.2 during stem growth and secondary xylem development in Populus...
