Response of Asplenium nidus to Drought Stress and Identification of Drought Tolerance Genes

To explore how responds to drought stress, and to mine drought-responsive genes for , we conducted a pot experiment in the IOT smart greenhouse. We measured a series of physiological and biochemical indexes for drought-treated plants, and analyzed the expression of drought-responsive genes in by RT-qPCR. The results show that the is a species with drought tolerance. inhibits plant photosynthesis and reduces life activities by limiting stomatal opening to adapt to drought. To resist drought stress, the changes the osmotic potential by increasing the proline content to maintain normal metabolic activities and prevents the damage of active oxygen by increasing the enzyme activities of SOD and POD. Based on the analysis of the relative expression levels of genes, and may be drought-resistant genes in . This study lays the foundation for in-depth research on drought tolerance mechanisms and drought-resistant gene mining of
