MEO — Nicotiana attenuata

Summary

A4A49_57237 (MEO, also known as SKP1A) encodes a SKP1-like protein containing Skp1 component dimerisation and POZ domains, and is annotated with multiple molecular functions including cullin family protein binding, auxin receptor activity, and MAPK phosphatase activity. In coyote tobacco (Nicotiana attenuata), this gene is associated with SCF complex assembly, regulation of gibberellic acid-mediated signalling, negative regulation of cytokinin signalling, and acropetal auxin transport. It is linked to numerous traits including seedling vigour, submergence tolerance, bacterial blight disease resistance, plant male sterility, photoperiod-sensitive flowering time, seed oil content, heat and cold stress tolerance, and increased drought tolerance. The gene is also associated with organ growth regulation, leaf margin serration, root hair density, and vascular tissue morphology.
