PNH — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0187760, designated HvPNH, encodes an Argonaute-family protein containing Piwi, PAZ and RNaseH-like domains, and is annotated with siRNA and miRNA binding activities. In barley, this gene is associated with somatic stem cell population maintenance, miRNA metabolism, pre-miRNA processing, gene silencing by miRNA-directed mRNA cleavage, regulation of meiotic DNA double-strand break formation, female meiotic nuclear division, acropetal auxin transport, and temporal regulation of development. It is linked to traits such as spikelet fertility, inflorescence development, leaf shattering, photosynthetic ability, gibberellic acid and cytokinin content, and responses to UV-A and UV-B light. Related genes in other species are associated with shoot apical meristem initiation, leaf polarity, antiviral immunity, meiosis, grain yield, and reproductive development.
