PIN2 — Nicotiana attenuata

Summary

A4A49_16286 (PIN2) on chromosome 3 of coyote tobacco (Nicotiana attenuata) encodes a serine-type endopeptidase inhibitor of the Protease_inhibitor_I20 family. The gene is associated with diverse biological processes including oviposition, chewing, trichome differentiation and branching, regulation of cell division and growth, secondary metabolism, ethylene anabolism, jasmonic acid signaling, secretion, regeneration, G1 and S phases of the cell cycle, nonsense-mediated mRNA decay, and virus-induced PTGS. It is also linked to protein content. Studies of related genes in other species connect the PIN2 family to root dry weight, stem diameter, transpiration rate, and seed dormancy.
