Conserved Subgroups of the Plant-Specific RWP-RK Transcription Factor Family Are Present in Oomycete Pathogens.

ABSTRACT: Nitrogen is a major constituent of proteins, chlorophyll, nucleotides, and hormones and has profound effects on plant growth and productivity. RWP-RK family transcription factors (TFs) are key regulators that bind to cis-acting elements in the promoter regions of nitrogen use efficiency-related genes and genes responsible for gametogenesis and embryogenesis. The proteins share a conserved RWPxRK motif; have been found in all vascular plants, green algae, and slime molds; and are considered to be a plant-specific TF family. In this study, we show that RWP-RK proteins are also widely present in the Stramenopila kingdom, particularly among the oomycetes, with 12-15 members per species. These proteins form three distinct phylogenetic subgroups, two of which are relatively closely relate
