Wide range of interacting partners of pea Gβ subunit of G-proteins suggests its multiple functions in cell signalling

► Interacting proteins (IPs) of pea Gβ subunit were screened by Y2H system. ► The colony filter lift and ONPG assays were employed to calculate β-gal activity. ► Characteristics of the seven IPs confirmed their role in stress and plant development. ► This study will enrich the knowledge of G-proteins signalling with respect to stress.
