| Study Title | Metabolic changes in seeds of malting barley produced under drought or elevated temperature |
| Study Type | Barley seed phenotyping and GC-MS based metabolomic analysis |
| Study Summary | Plants of a “Hana-type” landrace (B1) were taller, flowered earlier and produced heavier, larger and more vigorous seeds that resisted ageing longer compared to a semi-dwarf breeding line (B2). Drought significantly reduced seed yield in both genotypes, and elevated temperature reduced seed size. Genotype B2 showed partial thermodormancy that was alleviated by drought and elevated temperature, in line with lower abundance of the TF ABI5, a key regulator of seed dormancy and vigour. Metabolite profiling revealed clear differences between the embryos of B1 and B2. Drought, but not elevated temperature, affected the metabolism of amino acids, organic acids, osmolytes and nitrogen assimilation, in the seeds of both genotypes. |
