The Developmental Mechanism of the Root System of Cultivated Terrestrial Watercress.

ABSTRACT: A well-developed root system is crucial for the rapid growth, asexual reproduction, and adaptation to the drought environments of the watercress. After analyzing the transcriptome of the watercress root system, we found that a high concentration of auxin is key to its adaptation to dry conditions. For the first time, we obtained DR5::EGFP watercress, which revealed the dynamic distribution of auxin in watercress root development under drought conditions. Via the application of naphthylphthalamic acid (NPA), 4-biphenylboronic acid (BBO), ethylene (ETH), abscisic acid (ABA), and other factors, we confirmed that auxin has a significant impact on the root development of watercress. Finally, we verified the role of auxin in root development using 35S::NoYUC8 watercress and showed
