Conversely, lines over-expressing OsCKX4 show enhanced root system development.
We demonstrated enhanced root colonization by H. seropedicae in the presence of humic acids (Figure 1).
Citric acid enhanced root number at 6 mM level followed by 3 mM citric acid.
Applying organic amendments to polybag medium may improve soil physico-chemical properties and enhance root development.
Enhanced root growth parameters can be attributed to the presence of humic acid in vermicompost and vermiwash.
P. indica enhanced root and shoot biomass of colonized plants under both well-watered and water-deficit conditions.
Elevated CO2 enhanced root and shoot biomass, but this positive effect was reduced when plants were grown under high temperature.
Humic acids have been known to enhance root growth (Tallini et al. 1991) and nutrient uptake by increasing the root cell membrane permeability (Valdrighi et al. 1996).
Probably, enhanced root uptake combined with leaf/stem/sheath efflux transport can be an effective way to increase the Fe concentration in rice grains.
Enhanced root colonization and biocontrol activity was gained in B. amyloliquefaciens SQR9 by disruption of the global regulator abrB gene [23].
