Other claims from this paper (13)
- Intervention effect Cell division and elongation were inhibited in the apical hypocotyl and epicotyl after 2,4-D treatment.
- Intervention effect Cell elongation was inhibited 0.5-2 cm below the cotyledons.
- Intervention effect Radial enlargement was enhanced 0.5-2 cm below the cotyledons.
- Observation Fully elongated hypocotyl cells had slight radial expansion.
- Observation Cell divisions for lateral root formation began in the basal hypocotyl within 12 hours.
- Observation Cell divisions for lateral roots began in swollen zone B by 36 hours.
- Intervention effect 2,4-D blocked nucleic acid and protein synthesis in the apical hypocotyl zone.
- Observation Nucleic acid and protein synthesis resumed before growth recovered.
- Intervention effect After 2,4-D, RNA synthesis preceded DNA and protein synthesis elsewhere in the hypocotyl.
- Mechanism RNA synthesis increased the RNA/DNA ratio.
- Intervention effect 2,4-D preferentially induced r-RNA synthesis.
- Observation Newly synthesized RNA had normal base composition and size distribution.
- Mechanism The authors associated herbicidal action with renewed synthesis and subsequent tissue proliferation and death.
