Dataset belowing to Cultivating resilience: harnessing pyoverdine-producing Pseudomonas to contrast iron deficiency in cucumber plants

This improvement was observed with bacterial inoculation or pyoverdine application alongside an insoluble Fe source (ferrihydrite). Overall, the results suggest the beneficial impact of Pseudomonas RMC4 inoculation in alleviating symptoms of Fe deficiency. Future studies will investigate bacterial application under field conditions to assess its potential in reducing the need for synthetic Fe chelates in crop production.

In the present work, the efficiency of Pseudomonas RMC4 to mitigate Fe-deficiency symptoms of cucumber plants under hydroponic conditions was evaluated. The following determinations were performed: SPAD index, plant biomass, root morphology, ferric-chelate reductase activity, gene expression, and ionomic analysis. The results suggest that Pseudomonas RMC4 could help cucumber plants to reduce Fe-deficiency symptoms through plant development and improve the plant´s inherent mechanisms for Fe uptake, although, Pseudomonas RMC4 does not completely solve the Fe defficiency problem.
