Table II. Proteins associated with SGs and PBs in plants.

CCR4s, CAF1s, XRN4, and components of the mRNA-decapping complex are localized PBs but are only presented in Table I. AtLARP1A, a heat-specific cofactor of XRN4-mediated cotranslational decay, also accumulates in SGs and PBs under heat shock stress and is presented in Table I. All 11 Arabidopsis tandem zinc finger proteins are localized to cytoplasmic granules; however, only those with demonstrated colocalizations with known SG and/or PB components are included. AtSGS3 and AtAGO7 are typically present in distinct siRNA bodies but become positive for SG markers during heat stress. At, Arabidopsis thaliana; Os, Oryza sativa.
