Abstract
This invention discloses a *Pseudomonas* strain that controls citrus canker and promotes plant growth, along with its applications. *Pseudomonas* sp. CR1201 was deposited on January 17, 2024, at the Guangdong Provincial Microbial Culture Collection Center (GDMCC), with accession number GDMCC No.: 64290. The *Pseudomonas* strain disclosed in this invention is a new species in this genus, capable of effectively antagonizing *Xcc*, the causal agent of citrus canker, and promoting plant growth by producing siderophores and the plant growth hormone IAA. Therefore, *Pseudomonas* CR1201 disclosed in this invention can be used to prepare microbial preparations for controlling citrus canker, and also has significant application potential in microbial agents and biofertilizers for promoting plant growth and development.
