PR1A — Nicotiana attenuata

Summary

A4A49_13127 (PR1A) on chromosome 10 of coyote tobacco (Nicotiana attenuata) encodes a protein containing a CAP domain and a V5/Tpx1-like cysteine-rich secretory protein (CRISP) domain. The gene is associated with systemic acquired resistance, defense responses to other organisms, immune response, hypersensitivity, and detoxification. It is linked to jasmonic acid signaling, ethylene anabolism, phenylpropanoid anabolism, and nucleoside anabolism. Associations include responses to water, phenylalanine, and salinity inhibition, as well as sexual reproduction, embryogenesis, nuclear export, translation initiation, and homeostasis. The gene is connected to seed maturation, photosynthetic rate, drought tolerance, and resistance to Botrytis cinerea. The protein localizes to the extracellular region and vacuole. Studies of related genes in other species link the family to bacterial wilt, nematode, and virus resistance, as well as salt tolerance and herbivore defense.
