Abstract
The present invention provides a sweet orange stomatal density regulating gene, belonging to the technical field of plant genetic engineering, wherein the sweet orange stomatal density regulating gene is named CsSDD1, and the cDNA nucleotide sequence of CsSDD1 is shown in SEQ ID NO.1. The gene can negatively regulate the stomatal density of citrus leaves, and the gene can improve the resistance of citrus plants to drought and citrus canker by reducing the stomatal density of the leaves. The present invention also provides a coding protein of the sweet orange stomatal density regulating gene and its application.
