Fig. 7: Schematic model of the role of SGs in sequestering ATG proteins upon HS.
From: Stress granules sequester autophagy proteins to facilitate plant recovery from heat stress
During the HS phase, the ATG1/ATG13 complex, PI3K complex, and ATG5-ATG12 complex are recruited to SGs, resulting in the inhibition of autophagy. During the HS recovery phase, ATG proteins are released as SGs disassemble, thereby promoting autophagy to remove ubiquitinated proteins.
