CYCB2 — Zea mays

Summary

ZM00001EB272010 (ZmCYCB2) on maize chromosome 6 encodes a cyclin B2 protein with cyclin A/B-like and cyclin-box domains, and is annotated with cyclin-dependent protein serine/threonine kinase regulator activity. This gene is associated with mitotic G2/M transition, mitotic cell cycle phase transition, cell cycle progression, root meristem development, meristem identity, and root meristem size. It is linked to grain number, ear weight, ear diameter, cob diameter, floret number, ear length, yield trait, seed dormancy, germination rate, chlorophyll content, photosynthetic rate, quantum yield, leaf angle, plant male sterility, cytoplasmic male sterility, pollen fertility restoration trait, and salinity tolerance. Additional associations include C4 photosynthesis, phloem loading, oxidative phosphorylation, and mitochondrial processes. Related genes in other species are linked to male fertility and sterility.
