PR-1 — Nicotiana attenuata

Summary

A4A49_29708 (PR-1) in coyote tobacco (Nicotiana attenuata) on chromosome scaffold03254 encodes a PR-1 protein containing a CAP domain and a CRISP-related motif. This gene is associated with defense responses, including systemic acquired resistance, induced systemic resistance, innate immunity, and defense against other organisms. It is linked to salicylic acid and jasmonic acid anabolism, auxin signaling, programmed cell death, leaf senescence, abscission, secretion, detoxification, virus-induced PTGS, and sexual reproduction. The product localizes to the extracellular region and vacuole. Associations with traits include chlorophyll a and b content, carbohydrate content, and lignin content. Studies of related genes in other species link the PR-1 family to traits such as drought tolerance, plant height, chlorophyll content, fruit characteristics, and seedling vigor.
