What's a GeneRIF?

The fact that AGG1 and AGG2 are functionally interchangeable in some pathways implies that, at least for those pathways, signaling specificity resides in the distinctive spatiotemporal expression patterns exhibited by each gamma subunit.
Title: Signaling specificity provided by the Arabidopsis thaliana heterotrimeric G-protein γ subunits AGG1 and AGG2 is partially but not exclusively provided through transcriptional regulation.
AGG1, AGG2 and AGB1 control the immune responses and the regulation of cell wall composition.
Title: Arabidopsis heterotrimeric G-protein regulates cell wall defense and resistance to necrotrophic fungi.
GPA1, AGB1, AGG and RGS1 are involved in glucose attenuation of auxin-mediated lateral root formation.
Title: Glucose attenuation of auxin-mediated bimodality in lateral root formation is partly coupled by the heterotrimeric G protein complex.
Posttranslational modification of AGG1 is required for plasma membrane targeting.
Title: Dual lipid modification of Arabidopsis Ggamma-subunits is required for efficient plasma membrane targeting.
This research provides evidence of the functional association of alpha and beta with the gamma subunits in Arabidopsis, while also suggesting that plasma membrane localization may be critical for function of plant heterotrimeric G proteins.
Title: Over-expression of a truncated Arabidopsis thaliana heterotrimeric G protein gamma subunit results in a phenotype similar to alpha and beta subunit knockouts.
the Gbetagamma complex serves a signaling function in the ER independent of its function in the Galphabetagamma heterotrimer
Title: Heterotrimeric G protein signaling in the Arabidopsis unfolded protein response.
