RAN1 (TRAESCS1A02G413000) — triticum aestivum

Summary

TRAESCS1A02G413000 (TaRAN1) on wheat chromosome 1A encodes a Ran GTPase, a small GTP-binding protein with nucleocytoplasmic carrier activity and GTPase activity. The gene is associated with nucleocytoplasmic transport, ribosomal subunit export from the nucleus, miRNA export, phragmoplast assembly, cell plate formation, chromatin organization, and RNA splicing and methylation. TaRAN1 has been linked to drought and salt stress responses in wheat. Associations also include inflorescence branching, flowering time, vegetative-to-reproductive phase transition, root and seed development, leaf morphology, trichome distribution, stomatal closure, chloroplast development, and ethylene sensitivity. The protein localizes to the nuclear envelope, inner nuclear membrane, heterochromatin, and stress granules. Related genes in other species link the family to disease resistance, freezing tolerance, leaf senescence, trichome development, and ABA-mediated stress responses.
