The merging of distinct genomes, allopolyploidization, is a widespread phenomenon in plants. It generates adaptive potential through increased genetic diversity, but examples demonstrating its exploitation remain scarce. White clover (Trifolium repens) ubiquitous temperate allotetraploid forage crop derived from two European diploid progenitors confined to extreme coastal or alpine habitats. We sequenced and assembled the genomes transcriptomes this species complex gain insight into genesis...

Image-based phenotype data with high temporal resolution offers advantages over end-point measurements in plant quantitative genetics experiments, because growth dynamics can be assessed and analysed for genotype-phenotype association. Recently, network-based camera systems have been deployed as customizable, low-cost phenotyping solutions. Here, we implemented a large, automated image-capture system based on distributed computing using 180 networked Raspberry Pi units that could...

Abstract Allotetraploid white clover ( Trifolium repens ) formed during the last glaciation through hybridisation of two European diploid progenitors from restricted niches: one coastal, other alpine. Here, we examine which hybridisation‐derived molecular events may have underpinned clover's postglacial niche expansion. We compared transcriptomic frost responses clovers (an inbred line and an alpine‐adapted ecotype), extant descendants its progenitor species a resynthesised neopolyploid to...

Based on an initial collecting of database sequences from the gap junction protein gene family (also called connexin genes) in a few teleosts, naming these appeared variable. The reasons could be (i) that structure this is variable across or (ii) unfortunate naming. Rather clear rules for genes fish and mammals have been outlined by nomenclature committees, including orthologous ohnologous genes. We therefore analyzed teleosts more detail. covered range divergence times (eel, Atlantic...

Here, we examine which hybridisation-derived molecular events may have underpinned clover’s post-glacial niche expansion. We compared transcriptomic frost responses clovers (inbred line and an alpine-adapted ecotype), extant descendants its progenitor species a resynthesised neopolyploid to identify genes that were...

Abstract Background The influence of farming on plant, animal and microbial biodiversity has been carefully studied much debated. Here, we compare an isolate-based study 196 Rhizobium strains to amplicon-based MAUI-seq analysis rhizobia from 17,000 white clover root nodules. We use these data investigate the soil properties, geographic distance, field management nodule populations. Results Overall, there was good agreement between two approaches precise allele frequency estimates large-scale...

Abstract White clover is an agriculturally important forage legume grown throughout temperate regions as a mixed clover-grass crop. It typically cultivated with low nitrogen input, making yield dependent on fixation by rhizobia in root nodules. Here, we investigate the effects of and rhizobium genetic variation monitoring plant growth quantifying dry matter 704 combinations 145 169 genotypes. We find no significant effect variation. In contrast, can predict based few white markers strongly...
