RH4 — Brachypodium distachyon

Summary

BdRH4 (BRADI_1G34170V3) on Brachypodium distachyon chromosome 1 encodes a protein with DEAD-box RNA helicase domains and is annotated with RNA helicase activity, translation initiation factor activity, and additional molecular functions including tRNA-adenosine deaminase, histone acetyltransferase, and CDK activities. The gene is associated with cytoplasmic translational initiation, tRNA modification, asymmetric cell division, regulation of meiotic nuclear division and cell cycle G1/S phase transition, guard mother cell differentiation, pollen tube guidance, and RdDM. It is linked to traits including stem and culm length, leaf length, nitrate uptake, trichome morphology, and seed, embryo, root, and seedling development. Phenotypic associations include plant growth, reduced male transmission, pollen tube defects, reduced fertility, seed abortion, early embryo arrest, salt stress response, and cell cycle regulation. Related genes in other species are linked to cell cycle control, male gametophyte development, and embryo lethality.
