Other claims from this paper (12)
- Mechanism Auxin biosynthesis, transport and optimal levels are necessary for tomato root gravitropic growth.
- Intervention effect Exogenous auxin diminished tomato root gravitropic response.
- Intervention effect Auxin biosynthesis inhibitors diminished tomato root gravitropic response.
- Intervention effect An auxin transport inhibitor produced a robust agravitropic response.
- Mechanism Auxin regulates gravity perception through positive regulation and feedback control of starch accumulation.
- Intervention effect Exogenous NAA heightened starch synthesis.
- Intervention effect Exogenous yucasin dampened tomato root starch synthesis.
- Observation Cultivated cherry tomato Aisheng roots showed a slow gravitropic response, supported by time-series bending analysis.
- Observation After 36 h of gravity stimulation, tomato roots had 2770 differentially expressed genes.
- Observation After 3 h of gravity stimulation, only 58 differentially expressed genes were detected.
- Observation GO and KEGG analysis highlighted auxin response, starch and sugar metabolism, and cell wall modification as major regulatory pathways.
- Mechanism Auxin controls gravitropic bending through expression regulation of cell wall modification genes.
