BAT477 was derived from the cross (G3834 × G4493) × (G4792 × G5694) and combines deep rooting ability with greater water uptake efficiency (White et al. 1994a, b; Beebe et al. 2010).
First, the Mesoamerican gene pool advanced lines BAT 477 was selected based on its deep rooting ability and known drought tolerance [ 35], and second, the Andean gene pool genotype G19833 was selected based on resistance to both Al-toxicity and low phosphorus soil stresses [ 36, 37].
But a peek into its history shows a deep-rooted ability to reinvent itself.
Additionally, Paulownia can be used as an environmental protection tree because of its deep root system and ability to grow on nutrient-poor soil [ 1, 4].
P. juliflora's high coppicing ability and deep roots enable them to survive in drylands where they provide a number of benefits including alternative energy sources (Ayanu et al. 2015).
To enhance a crop's ability to avoid drought stress, therefore, the introduction of genes responsible for deep rooting into shallow-rooting cultivars is a promising breeding strategy.
The ability to grow deep roots is currently the most accepted target trait for improving drought resistance, but genetic variation has been reported for a number of traits that may affect drought response.
Our nominee must have deep roots in our party as well as the ability to appeal to liberal idealists, greens and working-class Londoners of all political persuasions.
He could not influence in any meaningful manner the national narratives that had sunk deep roots in other European countries and thus undermined those countries' ability to adapt.
The ability to maintain such high transpiration rates seems to be mainly due to the trees developing deep root systems (>4.8 m deep) which exploited the moisture stored in the sub-soil and regolith (Clulow et al. 2011).
