Other claims from this paper (9)
- Observation GRG177 had significantly greater seed weight and seed volume than the control germplasm GRD328.
- Observation GRG177 had a larger silique surface area than GRD328.
- Observation GRG177 had higher yield per plant than GRD328.
- Observation GRG177 showed a notable reduction in silique number per plant and seed number per silique.
- Observation GRG177 had significantly higher zeatin riboside content in the early stage of seed development.
- Observation IAA and ABA levels were significantly up-regulated in the late stage of seed development in GRG177.
- Mechanism Paraffin-section anatomy confirmed that enhanced cell division in the early stage and improved cell expansion in the later stage underpin high TSW formation.
- Observation BSA-seq mapped four TSW-related QTLs.
- Observation BSA-seq screened 13 candidate genes involved in IAA, ZR and ABA signaling pathways.
