▶ AI Summary
The study examined how heat stress alters the protein and lipid makeup of plastoglobules and thylakoids in the B73 maize inbred line, revealing increased plastoglobule size, number, and adjacent lipid droplets over time. Key changes included elevated triacylglycerol, plastoquinone derivatives, and specific proteins such as Fibrillin 1a/2, indicating a protective role in membrane remodeling and oxidative defense, and suggesting targets for enhancing heat resilience in maize.
