LHY — Nicotiana attenuata

Summary

A4A49_29102 (LHY) on chromosome 8 of coyote tobacco (Nicotiana attenuata) encodes a protein with DNA-binding transcription activator activity, RNA polymerase II-specific, and is also annotated with kinase regulator, histone acetyltransferase, and phosphorelay response regulator activities. LHY is associated with upregulation and downregulation of circadian rhythm, temperature compensation of the circadian clock, and photoperiod-sensitive flowering time. It is linked to positive regulation of anthocyanin metabolism, positive regulation of flavonoid anabolism, positive regulation of photomorphogenesis, and negative regulation of leaf senescence. Associations extend to numerous agronomic traits: leaf area, vegetative vigor, seed set, fruit set, root system morphology, photoperiod sensitivity, light quality responses (blue, far-red, UV), nutrient responses (phosphorus uptake, iron and cadmium concentration), temperature stress response, aphid response, and spot blotch. The gene is also connected to flower opening rhythm, floral scent production, and benzyl acetone emission.
