ARF19 acts as a transient auxin response enhancer during root gravitropism
{{output}}
Root gravitropism is regulated by an auxin gradient, causing the root to reorient downwards with gravity. Transcriptional activator auxin response factors (ARFs), such as ARF5, ARF6, ARF7, ARF8, and ARF19, play key roles in auxin signaling in seedling root tis... ...
