Transcriptional analysis of exogenous Spd-mediated relief mechanism of tomato tolerance to low iron stress.

Taking 'micro Tom' tomato as the test material, the water culture method was used to simulate the low iron environment, and Exogenous Spd was sprayed on the leaves as the regulatory substance to study the molecular response mechanism of Tomato Seedlings under low iron stress, which provided a theoretical basis for the regulation of tomato low iron tolerance based on Exogenous Spd.
