PNH — Daucus carota subsp. sativus

Summary

DCAR_024186 (DcPNH) on carrot chromosome 7 encodes a PAZ domain-containing protein with multiple annotated molecular functions including histone ubiquitin ligase and deubiquitinase activities, superoxide dismutase activity, dsRNA and siRNA binding, and RNA endonuclease activity. The gene is associated with miRNA and siRNA processing, gene silencing, phloem development, somatic stem cell maintenance, and temporal regulation of development. It is linked to traits including leaf and flower morphology, root phototropism, lignin biosynthesis, photosynthetic ability, cytokinin and gibberellic acid content, UV light sensitivity, and osmotic response. Phenotypic associations include leaf polarity, auxin signalling, virus resistance, seed dormancy, germination time, and arbuscular mycorrhizal colonization. Related genes in other species are associated with developmental timing, organ polarity, floral development, heat tolerance, and fruit yield.
