PNH — Daucus carota subsp. sativus

Summary

DCAR_027248, also known as DcPNH, encodes an Argonaute family protein containing Piwi, PAZ, and RNaseH-like domains, and is annotated with diverse molecular functions including siRNA binding, RNA endonuclease activity, and histone ubiquitin ligase activity. In carrots, this gene on chromosome 8 is associated with miRNA and siRNA processing, gene silencing, phloem development, somatic stem cell maintenance, and temporal regulation of development. It is linked to numerous traits including leaf morphology, root phototropism, flower development, lignin biosynthesis, photosynthetic ability, gibberellic acid and cytokinin content, and responses to UV light and osmotic stress. Phenotypic associations include leaf polarity, virus resistance, auxin signalling, arbuscular mycorrhizal colonization, seed dormancy, germination time, and reduced stomatal index. Related genes in other species connect the family to developmental timing, organ polarity, floral development, heat tolerance, and fruit yield.
