Stepwise evolution of the developmental and symbiotic functions of DELLA in land plants

Summary DELLA proteins play diverse roles in development, plant-microbe interactions and stress responses, and are regulated by the hormone gibberellic acid (GA) in flowering plants. Here, we investigated the evolutionary conservation of functions of the single DELLA ortholog in...

A CsWRKY46-CsPBL9-CsARI1 tripartite regulatory module coordinates H2O2 production and callose deposition in citrus fruit immunity

Plant immunity against pathogens involves multiple immune responses and intricate regulatory networks. However, how immune networks are deployed in fruit remains poorly understood. Here, we show that citrus fruit immune responses, including hydrogen peroxide (H 2 O 2 ) production...

TurboID ‐based proteomic profiling reveals proxitome of the IRT1 metal transporter and new insight into IRT1 endocytosis

Summary Iron Regulated Transporter1 (IRT1) is the major root iron transporter responsible for broad‐spectrum metal absorption in Arabidopsis thaliana root epidermal cells. Non‐iron metal substrates of IRT1 were recently shown to regulate IRT1 cell surface levels by endocytosis an...
