B-1 — Zea mays

Summary

ZmB-1 (ZM00001EB200350) on maize chromosome 4 encodes a protein containing CDPK, EF-hand, and protein kinase domains, and is annotated with calcium-dependent protein kinase activity, red/far-red light photoreceptor activity, and nitrate transmembrane transporter activity. The gene is associated with C4 photosynthesis, nitrate transmembrane transport, potassium ion import, response to symbiont, and appressorium formation. It has been linked to traits including tassel branch number, leaf curling, photosynthetic ability, carotenoid content, photoperiod-sensitive flowering time, water stress response, glyphosate sensitivity, and nitrate content. Associations also include root-to-shoot nitrate transport, salt tolerance, seed longevity, cadmium resistance, and lateral root development. Related genes in other species are linked to nitrate uptake, lateral root proliferation, and drought tolerance.
