摘      要：A hallmark of plant development is *** system architecture modulation in response to fluctuations of nutrient and water supply is a case in point(Giehl et al.,2014).The formation and length of lateral roots or the density of root hairs are strongly influenced by the availability of macro-and *** actively forage for mineral-rich patches in the typically heterogeneous soil environment and adjust their development systemically to increase the surface for nutrient ***,the opposite can happen as well.A recent study by Wang et al.(2023)convincingly demonstrated an active avoidance of unfavorable conditions by rice *** the seminal root of rice seedlings was placed between two agar blocks,one of them containing cations at toxic concentrations,adventitious roots developed only on the non-stress side,while development on the stress side was arrested(Figure 1).Besides,far more lateral roots were formed than in the absence of asymmetrically applied *** a while,this resulted in a total root biomass equivalent to that of control *** roots,in other words,had successfully shifted away from the stressful environment.
