Other claims from this paper (8)
- Intervention effect Cr(VI) treatment decreased rice PME activity.
- Intervention effect Pro application increased PME activity.
- Intervention effect Pro promoted transcription of several PME-related genes.
- Association OsPME7 had one of the highest positive expression variation factors between Cr(VI) and Pro plus Cr(VI).
- Association OsPME9 had one of the highest positive expression variation factors between Cr(VI) and Pro plus Cr(VI).
- Intervention effect Pro significantly increased pectin content in chromium-stressed rice.
- Intervention effect Proline increased chromium concentration in rice roots compared with Cr(VI) alone.
- Mechanism The authors infer that proline increases cell-wall Cr(VI) adsorption through PME activity and pectin content.
