WASF1 and infection: The SCAR/WAVE complex is involved in many processes contributing to important crop traits, such as stomatal dynamics and water use efficiency, infection thread formation during root nodulation, and control of cellular growth that impacts organ architecture and the adhesive properties of cells in the context of a tissue (Deeks et al. 2004; El-Assal Sel et al. 2004; Fu et al. 2013; Li et al. 2004; Ning et al. 2016; Zhou et al. 2016).
