MLO — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.1HG0065860, designated MLO on barley chromosome 1H, encodes a calmodulin-binding membrane protein. The gene is associated with immune response, programmed cell death, leaf development and senescence, and host invasion processes including invasive growth and cell polarization. It is linked to endosomal and vesicle transport, protein polyubiquitination, and virus-induced post-transcriptional gene silencing. Associations with powdery mildew resistance, leaf necrosis and chlorosis, and grain yield and fertility traits are recorded. Related genes in other species link it to resistance to powdery mildew, and sequence similarity connections extend to traits such as seed germination, chlorophyll content, and stomatal opening.
