Abstract

Polyploidization promotes the functional diversification of autophagy in plants, expanding autophagy-associated genes (AAGs) to support processes like chloroplast division and flowering. Analysis of 92,967 AAGs in Arabidopsis thaliana, Solanum lycopersicum, Camellia oleifera, and 74 other plant species shows that 45.69% of AAGs are polyploidy-related, highlighting polyploidy's role in linking autophagy to plant-specific functions.
