DESCRIPTION:Location:   \n Affiliation: \n Host:\n Model-to-crop translatio
 n:interaction between mineral-nutrient availability and steroid hormones 
 Plants acquire essentialmineral nutrients from inherently heterogeneous so
 ils\, in which phosphateavailability vary. Consequently\, plants have deve
 loped adaptive strategies tocope with low phosphate levels\, including alt
 ernation between root growth enhancementand attenuation. Using the plant m
 odel Arabidopsis\, it was recently found thatthe steroid hormone signaling
  enables root growth plasticity in response tolimited availability of this
  nutrient.  In addition\, the molecularmechanism that operates at the ba
 se of this interaction was revealed. The aimof this study was to: i) trans
 late these findings to crop using tomato and ii)establish physiological gr
 owth conditions outside agar plates that facilitatesthe analysis of the hi
 dden root system in both plants.  Indeed\, weestablished an inert soil-l
 ike substance that allowed us to control the mineralcomposition in the med
 ia and thus\, to compare root responses of both plantspecies. As part of t
 he translation strategy\, we took a pharmacology approachto perturb hormon
 al levels in tomato and use the CRISPR/CAS9 method to createloss-of-functi
 on mutations in select key transcription factors. This revealedthat the ro
 ot system of tomato is shaped by low phosphate availabilitydepending on th
 e steroid signaling. However\, this modulation differed from thatoccurring
  in Arabidopsis\, highlighting the flexibility and adaptive response ofdif
 ferent plants to their environment. In addition\, we show that the hormone
 signaling affected the homeostasis of select elements\, but these were not
 common between tomato and Arabidopsis. Collectively\, these data demonstra
 tethat the interaction between phosphate availability and steroid hormones
  hasdifferent outcome in different plants. Thus\, this study highlights th
 e advantageof using various plant systems towards understanding of how pla
 nts makedevelopmental decisions in response to heterogeneous soil.  Thek
 nowledge in crop could be also harnessed for improving agriculture.
