Heslop-Harrison JS. 2017. Morphology, adaptation and speciation. Annals of Botany 120(7): 621-624. https://doi.org/10.1093/aob/mcx130The study of plant evolution and development in a phylogenetic context has accelerated research advances in both areas over the last decade. The addition of a robust phylogeny for plant taxa based on DNA as well as morphology has given a strong context for this research. Genetics…

Annals of Botany 120(2): 183-194. https://doi.org/10.1093/aob/mcx079 (Free access). Polyploidy, defined as whole genome duplication, is present in almost all lineages of higher plants, with multiple rounds of polyploidy occurring in most extant species. This Annals…

Domestication, polyploidy and genomics of crops and weeds PAGXXV
Plant and Animal Genome Conference in San Diego #PAGXXV each January is the chance to join 3500 people working in genomics. I presented a talk on the molecular cytogenetics group’s work, starting with consideration of early stages of crop domestication, and then thinking about how we can make agriculture more sustainable. I also considered weeds,…
Haploid callus from a diploid Musa accession for genome analysis

Haploid and doubled haploid plants are of considerable value in genetic studies, genomics and plant breeding, allowing characterization and exploitation of genes where only one allele is present. Inbred banana…

The origin of saffron: Crocus sativus
Our research projects are studying the origins and diversity in several polyploid crops: banana, wheats, Brassica, Panicum millets, Nicotiana and the saffron crocus, Crocus sativus. The spice saffron is the stigmas of the flowers, and widely appreciated in Indian and Mediterranean cooking. Saffron crocus is a sterile triploid, with 2n=3x=24 chromosomes – that is, 3…
