Abstract

Ribosome biogenesis is a complex process requiring rRNA and several proteins. Ribosomal RNA processing factor 2 (RPF2) is known to be involved in the processing of 25S rRNA and 5S rRNA. We report the role of RPF2 in plants in growth, development and drought stress response. RPF2 interact with plant-specific SOC1, NAC1 transcription factors and with RPL10, and plays a role in the regulation of flowering and root development. The RPF2 binds to promoters of flowering and root-associated genes. Overexpression of RPF2 in Arabidopsis and N.benthamiana showed a robust phenotype, higher trichomes and early flowering, and the mutants or RNAi lines showed the opposite phenotype. RPF2-OE plants are insensitive to ABA, and mutants showed higher water loss. The RPF2-OE plants are resistant to drought stress compared to wild type and RNAi lines.
