Genome resources for underutilised legume crops: genome sizes, genome skimming and marker development.
Underutilised crops suffer from under-investigation relative to more mainstream crops, but often possess improved stress tolerance and/or nutrition, making them potentially important for breeding programmes in the context of climate change and an expanding human population. Developing basic genome resources for underutilised crops may therefore catalyse analyses to facilitate their... -

First Whole Genome Sequence and Flow Cytometry Genome Size Data for the Lichen-Forming Fungus Ramalina farinacea (Ascomycota).
Lichen-forming fungi are a diverse and ecologically important group of obligate mutualistic symbionts. Due to difficulties with maintaining them in culture and their extremely slow growth, lichenologists are increasingly opting for metagenomic sequencing followed by symbiont genome separation using bioinformatic pipelines. However, without knowing the true genome size of the...Llewellyn, Theo ; Mian, Sahr ; Hill, Rowena ; Leitch, Ilia J ; Gaya, Ester
