HTA8 — Arabidopsis thaliana

Summary

AT2G38810, also known as HTA8, encodes a probable histone H2A variant 2 (H2A.Z) in thale-cress (Arabidopsis thaliana). The protein contains a histone-fold domain and is annotated as a structural constituent of chromatin, with annotated activities including chromatin binding, DNA binding, protein heterodimerization, and various enzymatic activities such as histone acetylase and deacetylase activity, protein kinase activity, and PRMT activity. HTA8 is associated with thermomorphogenesis, detection of temperature, regulation of chromatin organization, heterochromatin organization, petal formation and development, shoot regeneration, vegetative phase change, and memory. It is linked to reactive oxygen species production, lateral root development, and gravitropic response. The gene is also associated with numerous traits including flowering time, leaf morphology and size, photosynthetic rate, stomatal closure, anthocyanin content, germination rate, and responses to high temperature, light intensity, jasmonic acid, cytokinin, and brassinosteroids.
