LOB — Asparagus officinalis

Summary

A4U43_C05F1970, also known as AoLOB, encodes a LOB domain-containing transcription factor on asparagus chromosome 5. The product exhibits DNA-binding transcription factor activity, with both activator and repressor functions, protein homodimerization and identical protein binding. AoLOB is associated with specification of symmetry, adaxial/abaxial axis polarity, organ boundary specification, leaf formation, petal development, root development, and asymmetric cell division. It is linked to regulation of innate immune response, response to virus, shade avoidance, phenylpropanoid metabolism, and ROS metabolic process. The gene is associated with yield, flowering time, photoperiod-sensitive flowering, leaf morphology traits, seed and fruit growth and development, anthocyanin content, brassinosteroid and abscisic acid sensitivity, and abiotic stress response. Localization evidence places the product in the nucleus, nucleolus, mitochondria, and condensed chromosome. Related genes in other species link the LOB family to leaf adaxial-abaxial polarity, leaf morphology, and vein formation.
