Towards a better monitoring of seed ageing under ex situ seed conservation

摘要: Long-term conservation of 7.4 million ex situ seed accessions held in agricultural genebanks and botanic gardens worldwide is a challenging mission for human food security ecosystem services. Recent advances biology genomics may have opened new opportunities effective management germplasm under long-term storage. Here, we review the current development tools assessing ageing research genomics, with focus on exploring their potential as better monitoring ageing. Seed found to be associated changes reflected reactive oxygen species mitochondria-triggered programmed cell deaths, expression antioxidative genes DNA protein repair genes, chromosome telomere lengths, epigenetic regulation related (microRNA methylation) altered organelle nuclear genomes. Among these changes, signals from mitochondrial genomes show most promise use predict Non-destructive non-invasive analyses stored seeds through calorimetry or imaging techniques are also promising. It clear that into developing advanced supplement traditional germination tests will fruitful germplasm.
