The work could have multiple applications in the sector agronómico and abaratar in the future the cost of the seeds

This mechanism is new since the tolerance to estreses like the aging always had associated to another hormone, the acid abscísico, that regulates defences based in proteins and small protective molecules, in place to promote the growth of structures as it does the giberelina.

The study has developed in plants it model Arabidopsis thaliana, a species that presents big advantages for the investigation in molecular biology. The researchers tracked half million of seeds, that corresponded to 100.000 lines of Arabidopsis mutated. “Finally, in the study analyse four mutants and check the incidence on the longevity of the seeds of the plant when entering him the sobrexpresión of the gene ATHB25”, aims the professor of investigation of the CSIC Ramón Serrano.

The researchers of the centre work now in improving the longevity of different species of interest agronómico, between them the tomato or the wheat.

“In the past cultivated a lot of species of distinct plants, but have lost many of them, since what prevails today are the criteria of performance. To guarantee the conservation of species created the Banks of Germoplasma, although these require to regenerate periodically the seeds. With this strategy could expand the terms of regeneration”, stands out Bueso. While, in the case of the agriculturalists, Serrano explains that “when increasing the useful life of the seeds, would reduce the cost derived of his purchase”.
