gravitropism mutant向重力性突变体
negative gravitropism负向重力性
Plant Gravitropism植物向重力性
Lateral root development and gravitropism are regulated by polar auxin transport (PAT), and auxin efflux inhibitors (AEI) inhibit LR growth and tropism.
生长素极性运输 (polar auxin transport, PAT) 对侧根发生和根尖向地性起着重要的调节作用，添加外源生长素极性运输抑制剂不仅抑制了侧根发生，同时还使根尖丧失了向地性。
