Building on our decade-long evolutionary research on Lord Howe Island (LHI), the student will use this emerging model system to disentangle the genomic underpinning of sympatric speciation in plants. Uniquely, we have identified a pair of closely related palm species that have evolved on the minute LHI by adapting to different soil types. One of the species, Howea forsteriana
, evolved on calcareous soils deposited by the sea one million years ago, which lead to water, salt and metal stresses whilst affecting flowering phenologies. Thus, the Howea
palms of LHI represent an invaluable system to disentangle how species in general, and plants in particular, have evolved to cope with environmental stresses, and how soil chemistry and microbes can drive evolution and adaptation to soil stressors. Because the scenario of speciation in Howea
palms involves flowering time displacement in response to adaptation to drought, salt and other soil stressors, and because the genes involved in these mechanisms are expected within specific genomic islands, we propose a comparative genomic approach to disentangle stress tolerance in crop palms (African oil palm, coconut palm). (i) The student will look at the underlying genomics of the species split, and identify genomic islands and loci likely involved in speciation and stress tolerance. (ii) S/he will attempt to validate candidate genes, e.g. attempting to transfer Howea
genes across Howea
species, and/or into oil palms, the latter having a generation time much more tractable for such functional confirmation experiments. (iii) Finally, the student will apply this knowledge to evaluate whether similar genes are in operation for stress tolerance in crop palms (oil/coconut). This will involve field trials in Africa in partnership with collaborators in Ivory Coast and Ghana CASE partner the National Botanic Gardens of Wales will provide the ideal platform for outreach and public engagement with this research.
