Mammalian phosphodiesterase inhibitors increase cAMP levels and enhance plant cell reprogramming toward embryogenesis across diverse species.
- Why it matters: Low efficiency of somatic embryogenesis limits plant breeding and biotechnology applications, and understanding signaling mechanisms like cAMP could improve this process.
- What they did: Four PDE inhibitors were tested in three embryogenesis systems from Brassica napus, Hordeum vulgare, and Quercus suber, showing increased embryogenic reprogramming and gene expression linked to embryogenesis.
- The result: PDE inhibition elevated cAMP levels and key embryogenesis regulator expression, suggesting cAMP signaling as a conserved factor in embryogenic induction and potential for improving plant regeneration protocols.
