| 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. |

| Project Title: | Germination physiology |
| Project Summary: | Seeds are the major component of feed and food and the majority of crops are produced from seeds. This means that as the world population increases so does the demand for seed. Sub-optimal seed performance can lead to major economic losses and food supply shortages and this is set to be aggravated by climate change as abiotic constraints negatively impact seed quality. Our aim is to decrypt the central mechanisms that mediate germination while exploring their potential in applications to enhance seed performance. In particular, we seek to understand how seeds interpret and respond to environmental variations pre- and post-harvest. We apply a multidisciplinary approach using molecular genetics, multi-omics, statistical learning, bioinformatics, biochemistry, histology and physiology to study seeds from a wide range of species such as oilseed crops (e.g. camelina, cabbage), legumes (e.g. bean, lentil), cereals (e.g barley, maize) and vegetable crops (e.g. tomato and lettuce). Nonetheless, the majority of our fundamental research focuses on the genetic model Arabidopsis. |
