Recognizing the importance of the field, and the growing interest in such data, the Annals of Botany Company sponsored the first ‘Angiosperm Genome Size Workshop and Discussion Meeting’ (probably the first international meeting devoted exclusively to this specialized topic), hosted at the Royal Botanic Gardens, Kew in Se… More than 50 plant genomes have been published over the past 13 years [5], which provides an unprecedented opportunity to explore the mechanisms of plant genome bloating versus purging, and the mechanisms that govern the architecture of plant genomes. Genome size diversity and its impact on the evolution of land plants. Angiosperms are unique among land plant lineages in the occurrence of key genes in the RNA-Directed DNA Methylation (RdDM) pathway. I lead a team of Kew scientists investigating character evolution in plants. The Plant DNA C-values Database currently contains data for 5150 different plant species. Â.

THE PLANT DNA C-VALUES DATABASE We conduct research aimed at identifying and understanding (i) how different plant traits interact and evolve to generate the diversity of plant life, and (ii) how key characters influence, or are influenced by, global environmental change. Ma, L., Hatlen, A., Kelly, L.J., Becher, H., Wang, W., Kovarik, A.R., Leitch, I.J., Leitch, A.R. This diversity is seen at many levels including: This project aims to document and understand the origin, consequence and evolutionary significance of this striking genome diversity across land plants, and its impact in determining how, where and when a plant lives and responds to environmental change. However, despite our realisation of the substantial implications of this genomic diversity for the biology of the plants, little is known about the underlying mechanisms that promote changes at the genomic levels and the evolutionary and ecological consequences over time. Collating new data into … The particular characters currently under study range across all levels of plant organization from the genomic to the whole plant level. Plants are remarkable in the diverse ways in which they organise, accumulate and express the DNA comprising their genomes. Conserving some of the world’s rarest, endangered and useful tree and shrub species as well as conducting vital tree conservation research in order to retain a significant resource for humanity.
