Plants have evolved various strategies to adapt nutrient limited condition. As a reflection, parasitic plants and legume species produce specialized organs, the haustorium and the nodule, respectively, in order to acquire unique routes for nutrient uptake through intimate interaction with surrounding organisms. Initiation and developmental progression of haustorium and nodule require signal guidance from the interacting partners and acquisition of new cell fates regulated by intrinsic hormonal and gene networks. Albleit their independent evolutionary origin, emerging studies have shown a certain degree of commonality in the regulatory system of both organs. This review (Cui et al., 2023. Curr. Opin. Plant Biol.) summaries recent advances on the molecular control of haustorium development in Orobanchaceae species and root nodule establishment in legume family with step-by-step comparisons, with the focus on the common regulatory roles of phytohormones and environmental nitrogen at different stages of corresponding organogenesis.
