DOG1 — Arabidopsis thaliana

Summary

AT5G45830, known as DOG1 (DELAY OF GERMINATION 1), encodes a protein containing a seed development/stress response regulatory domain and a TGA domain, and exhibits sequence-specific DNA binding and protein binding activities. DOG1 is associated with seed dormancy processes, entry into dormancy, and germination timing, as well as abscisic acid anabolism and gibberellin catabolism. The gene is linked to germination ratio, seed longevity, seed viability, seed size, drought sensitivity, salt stress response, flowering time, and seedling establishment. DOG1 also shows associations with sugar signaling, glucose sensitivity, and thermoinhibition. The protein localizes to both the cytoplasm and nucleus, and is connected to DNA imprinting, nucleosome disassembly, and transcription by RNA polymerase II. Related genes in other species further support the gene's association with seed maturation and stress responses.
