PAL — Nicotiana attenuata

Summary

A4A49_27559 (PAL, TPA1) in coyote tobacco (Nicotiana attenuata) encodes a phenylalanine ammonia-lyase (EC 4.3.1.24) with ammonia-lyase and protein dimerization activity, and also DNA-binding transcription factor activity. The gene is associated with floral scent production and herbivore defense response in this species. It is associated with salicylic acid and L-phenylalanine breakdown, cinnamic acid and phenylpropanoid anabolism, lignin breakdown, cell wall thickening, guard cell fate commitment, drought recovery, response to low humidity and UV-B, and negative regulation of cytokinin signalling. Associations also include photosynthetic rate, respiration rate, UV light sensitivity, disease resistance, wound response, anthocyanin accumulation, and tolerance to salt, freezing, chilling, copper stress, and pathogens including Corynespora cassiicola and Cucumber mosaic virus. The protein localises to the cytosol, nucleus, and SCF complex.
