PNH — Daucus carota subsp. sativus

Summary

DCAR_018752 (symbol DcPNH) on carrot chromosome 5 encodes a protein containing Argonaute_Mid_dom, Piwi_ago-like, ArgoL2, ArgoL1, Argonaute_N, Piwi, PAZ_dom, PAZ_dom_sf, RNaseH_sf, and RNaseH-like_sf domains, with annotated molecular functions including siRNA binding, RNA endonuclease activity, dsRNA binding, and histone ubiquitin ligase activity. The gene is associated with miRNA metabolic process, LsiRNA processing, pre-miRNA processing, gene silencing by miRNA-directed mRNA cleavage, phloem development, somatic stem cell population maintenance, and temporal regulation of development. Associations with traits include leaf and flower morphology, root phototropism, lignin biosynthesis, photosynthetic ability, vegetative growth time, and gibberellic acid and cytokinin content. Phenotypic associations link DcPNH to leaf polarity and shape, auxin signalling, virus resistance, juvenile-to-adult transition, seed dormancy, and reduced seed longevity. Related genes in other species are associated with histone ubiquitination, early flowering, pale leaves, and reduced seed dormancy.
