YS1 — Hordeum vulgare subsp. vulgare
Summary
HORVU.MOREX.R3.3HG0254240 (YS1, HvYS1) on barley chromosome 3H encodes a pentatricopeptide repeat (PPR) protein with RNA nuclease activity, RNA and mRNA binding, and zinc binding. The gene is associated with chloroplast and mitochondrial mRNA modification, specifically cytidine-to-uridine editing, as well as thylakoid membrane organization, photosystem I assembly, regulation of chlorophyll biosynthesis, and response to high light intensity and cold. It is linked to chloroplast RNA editing, photosystem II assembly, chloroplast development, and abscisic acid sensitivity. The protein localizes to the chloroplast stroma, plastid, mitochondria, vacuole, and cytoplasm. Related genes in other species are linked to photosynthetic acclimation, pale green leaves, and defects in ndhD RNA editing and photosystem II function.
