Other claims from this paper (13)
- Association Auxin accumulation enhanced OsWOX10 expression.
- Mechanism Auxin accumulation promoted lateral root primordia into long thick L-type roots.
- Intervention effect Removing the coleoptile inhibited auxin accumulation at the incision.
- Intervention effect Blocking shoot-to-root auxin transport inhibited auxin accumulation.
- Intervention effect Removing the coleoptile abolished compensatory lateral root growth.
- Intervention effect Blocking auxin transport abolished compensatory lateral root growth.
- Observation OsPIN1b, OsPIN1c, and OsPIN9 were expressed in root vasculature and epidermis.
- Mechanism The three PIN proteins redundantly control shoot-to-root auxin transport and root tip auxin distribution.
- Intervention effect Triple PIN knockout caused severe growth inhibition and loss of gravitropism.
- Intervention effect Triple PIN knockout diminished cutting induced auxin accumulation and compensatory lateral root growth.
- Intervention effect Knockout of one or two PIN genes had little effect.
- Association Weakened compensatory lateral root growth hindered plant growth and nutrient absorption after cutting.
- Mechanism Jasmonic acid, reactive oxygen species, and cytosolic calcium signaling were not involved in compensatory lateral root growth.
