Cyanotypic frequencies in adjacent and mixed populations of Trifolium occidentale Coombe and Trifolium repens L. are regulated by different mechanisms.
The cyanogenic polymorphism in Trifolium repens is caused by the variation in two genes, the interaction of which produces four distinct cyanotypes. Along the Atlantic coasts of Bretagne, T. repens is sometimes found in populations mixed with the related species Trifolium occidentale, although the latter species usually occurs only in a narrow fringe along the coast, whereas T. repens is a more...
متن کاملRecurrent gene deletions and the evolution of adaptive cyanogenesis polymorphisms in white clover (Trifolium repens L.).
Understanding the molecular evolution of genes that underlie intraspecific polymorphisms can provide insights into the process of adaptive evolution. For adaptive polymorphisms characterized by gene presence/absence (P/A) variation, underlying loci commonly show signatures of long-term balancing selection, with gene-presence and gene-absence alleles maintained as two divergent lineages. We exam...
متن کاملNatural antisense transcripts of Trifolium repens dehydrins
Dehydrins (group 2 LEA proteins) tend to accumulate late in embryogenesis and in response to stress leading to cell dehydration (e.g., drought, low temperature, and salinity). The expression pattern of group 2 LEA genes is frequently associated with higher tolerance of crop plants to abiotic stresses such as cold and drought. All dehydrins have at least one conserved, lysine-rich 15-amino acid ...
متن کاملNatural antisense transcripts of Trifolium repens dehydrins
The recently described complex nature of some dehydrin-coding sequences in Trifolium repens could explain the considerable variability among transcripts originating from a single gene.1 For some of the sequences the existence of natural antisense transcripts (NAT s), which could form sense-antisense (SAS) pairs, was predicted. The present study demonstrates that cis-natural antisense transcript...
متن کاملA developmentally based categorization of branching in Trifolium repens L.: influence of nodal roots.
This study describes the successive stages of development of branches from axillary buds in fully rooted plants of Trifolium repens grown in near optimal conditions, and the way in which this developmental pathway differs when nodal root formation is prevented as plants grow out from a rooted base. Cuttings of a single genotype were established in a glasshouse with nodal root systems on the two...
