e6“Low phosphorus significantly changed root anatomy, causing a 9% increase in root diameter, a 31% decrease in the cross‐sectional area of individual trichoblasts, a 40% decrease in the cross‐sectional area of individual atrichoblasts, and 45% more cortical cells in cross‐section”

Other claims from this paper (14)
- Intervention effect Root hair density was about five times greater in low phosphorus media than in high phosphorus media.
- Intervention effect Root hair density decreased logarithmically as phosphorus concentration increased within the tested range.
- Intervention effect Root hair density increased under deficiencies of other nutrients, but less strongly than under low phosphorus.
- Intervention effect Indoleacetic acid increased root hair density under high phosphorus but had very little effect under low phosphorus.
- Intervention effect The auxin transport inhibitor CMPA increased root hair density under high phosphorus but had very little effect under low phosphorus.
- Intervention effect The ethylene precursor ACC increased root hair density under high phosphorus but had very little effect under low phosphorus.
- Intervention effect The ethylene synthesis inhibitor AOA increased root hair density under high phosphorus but had very little effect under low phosphorus.
- Intervention effect Low phosphorus increased root diameter by 9%.
- Intervention effect Low phosphorus decreased the cross-sectional area of individual atrichoblasts by 40%.
- Intervention effect Low phosphorus increased the number of cortical cells in cross-section by 45%.
- Intervention effect Low phosphorus increased the number of trichoblast files from eight to 12.
- Mechanism Two-thirds of the increase in root hair density under low phosphorus was caused by a higher likelihood of trichoblasts forming hairs.
- Mechanism Changes in root anatomy under low phosphorus accounted for 33% of the increase in root hair density.
- Intervention effect Initial root hairs were not sensitive to phosphorus availability.
