Heat stress survival: Unraveling the HsfA2-ACTIN dynamics in lily varieties

A research team has identified that the heat stress transcription factor HsfA2 and actin-interacting protein (AIP) LACTIN interact at the protein level in Lilium longiflorum "White Heaven," mediating gene expression and protecting cells from heat stress. This interaction does not occur in Lilium oriental "Siberia," potentially explaining the difference in heat resistance between the varieties.
