A simplified representation of the hormonal crosstalk network for the regulation of root growth under osmotic stress conditions, in a vascular cell expressing PIN1, demonstrating that the responses of auxin transporters, hormones and signalling components to osmotic stress are nonlinear and complex. Abbreviations: DR5p, DR5 regulated yellow fluorescent protein; DIIp, DII‐VENUS protein; PLSp, POLARIS peptide; PIN1, PIN1 auxin efflux transporter protein; AUX1, AUX1 auxin influx transporter protein; ET, ethylene; X, the unknown factor that regulates auxin transport from the aerial tissues; EIN2, EIN2 ethylene signalling protein; ERF1m, ERF1 mRNA transcript; ABA, abscisic acid; RD29Bm, RD29B mRNA transcript; CK, active cytokinin; ARR5m, ARR5 mRNA transcript; TCS, cytokinin response reporter; osmotic stress, the osmotic stress imposed by the growth medium. Red boxes group related activities.
