Light spectrum modulates stress and defense gene expression in potato (Solanum tuberosum L.) shoot tips during post-cryopreservation recovery.

ABSTRACT: Light intensity and spectral quality are two important factors that affect the cryopreservation success of plant germplasm. In a previous study, we found that light emitting diodes (LEDs) with 90% red and 10% blue (RB) light have a positive effect on potato (Solanum tuberosum L.) shoot tip recovery during post-cryopreservation regeneration. In the present study, transcriptome profiles of non-cryopreserved (-) and cryopreserved (+) potato shoot tips exposed to RB, cool white fluorescent tubes (CW) and full darkness (D) were compared. Results indicated that light spectrum significantly affects transcript numbers in post-cryopreserved samples resulting in 3,284 differentially expressed genes of recovering shoot tips exposed to CW, RB and D. Gene ontology (GO) enrichment analysis revealed that
