HHP1 — Nicotiana attenuata

Summary

A4A49_33012 (NaHHP1) on coyote tobacco chromosome scaffold02711 encodes a protein of the AdipoR/HlyIII-related family with DNA-binding, transcription factor and signaling receptor activities, and is associated with membrane, mitochondrial and nuclear localisation. The gene is linked to abscisic acid (ABA) and gibberellic acid responses, stomatal closure, and regulation of ABA anabolism and signaling. It has been connected to seed dormancy, endosperm development, seed morphogenesis, and seed longevity, as well as flowering time, leaf senescence, stamen morphology, pollen fertility, and male fertility. Associations also include responses to freezing, cold, drought, osmotic stress, oxidative stress, sucrose, and temperature stress, plus seedling growth and development, disease tolerance, and cell adhesion. Studies of related genes in other species link the family to cold tolerance, stomatal development, and freezing tolerance.
