Journal ArticleDOI
Heterotrimeric G Proteins Facilitate Arabidopsis Resistance to Necrotrophic Pathogens and Are Involved in Jasmonate Signaling
Yuri Trusov,James E. Rookes,David Chakravorty,D. J. Armour,Peer M. Schenk,José Ramón Botella +5 more
TL;DR: It is hypothesized that Gβγ acts as a direct or indirect enhancer of the jasmonate signaling pathway in plants and is coherent with the classic heterotrimeric mechanism of action.
Journal ArticleDOI
Heterotrimeric G Protein γ Subunits Provide Functional Selectivity in Gβγ Dimer Signaling in Arabidopsis
Yuri Trusov,James E. Rookes,Kimberley Tilbrook,David Chakravorty,Michael G. Mason,David J. Anderson,Jin-Gui Chen,Alan M. Jones,José Ramón Botella +8 more
TL;DR: It is shown that both Gγ subunits form functional Gβγ dimers and that each provides functional selectivity to the plant heterotrimeric G proteins, revealing a mechanism underlying the complexity of G protein–mediated signaling in plants.
Journal ArticleDOI
An atypical heterotrimeric G‐protein γ‐subunit is involved in guard cell K+‐channel regulation and morphological development in Arabidopsis thaliana
David Chakravorty,Yuri Trusov,Wei Zhang,Biswa R. Acharya,Michael B. Sheahan,David W. McCurdy,Sarah M. Assmann,José Ramón Botella +7 more
TL;DR: A new Arabidopsis G-protein γ-subunit (AGG3) that modulates morphological development and ABA-regulation of stomatal aperture is identified that implicates G-proteins in such a crucial agronomic trait.
Journal ArticleDOI
Extra-Large G Proteins Expand the Repertoire of Subunits in Arabidopsis Heterotrimeric G Protein Signaling
TL;DR: The XLG-Gβγ heterotrimers provide additional signaling modalities for tuning plant G protein responses and increase the repertoire of G protein heterOTrimer combinations from three to 12.
Journal ArticleDOI
Diversity of heterotrimeric G-protein γ subunits in plants
TL;DR: Phylogenetic analyses suggest that types C and B most probably originated independently from type A ancestors and a new flexible nomenclature for plant Gγ subunits is proposed.
