MEO — Nicotiana attenuata

Summary

A4A49_36321 (MEO, ASK12) in coyote tobacco (Nicotiana attenuata) encodes a SKP1-like protein containing a Skp1 component dimerisation domain and a POZ domain. The gene is associated with diverse molecular functions including MAPK phosphatase activity, cullin family protein binding, auxin receptor activity, and blue light photoreceptor activity. It is linked to SCF complex assembly, regulation of gibberellic acid-mediated signalling, acropetal auxin transport, and negative regulation of cytokinin signalling. Associations with agronomically relevant traits include bacterial blight disease resistance, submergence tolerance, seedling vigor, plant male sterility, photoperiod-sensitive flowering time, and seed oil content. The gene is also connected to drought tolerance, heat and cold stress tolerance, and root hair density. Related genes in other species link it to jasmonate perception, floral organ development, and defence against necrotrophic pathogens.
