Multiple origins and nrDNA internal transcribed spacer homeologue evolution in the Glycine tomentella (Leguminosae) allopolyploid complex.
Despite the importance of polyploidy in the evolution of plants, patterns of molecular evolution and genomic interactions following polyploidy are not well understood. Nuclear ribosomal DNA is particularly complex with respect to these genomic interactions. The composition of nrDNA tandem arrays is influenced by intra- and interlocus concerted evolution and their expression is characterized by ...
متن کاملMultiple origins of BBCC allopolyploid species in the rice genus (Oryza)
In the rice genus (Oryza), about one half of the species are allopolyploids. These species are not only important resources for rice breeding but also provide a unique opportunity for studying evolution of polyploid species. In the present study, we sequenced four biparentally inherited nuclear loci and three maternally inherited chloroplast fragments from all diploid and tetraploid species wit...
متن کاملAutogamy and allogamy in genus Lathyrus
Introduction In Tunisia the genus Lathyrus is represented by 15 native species , distributed essentially in marginal environments in the north of the country. Many of them are of considerable agronomic interest as forage (L. ochrus and L. articulatus) and as human food (L. cicera and L. sativus). These species are under utilised and in the past little effort has been made to expand the selectio...
متن کاملIsolated history of the coastal plant Lathyrus japonicus (Leguminosae) in Lake Biwa, an ancient freshwater lake
BACKGROUND AND AIMS Lake Biwa is one of the world's few ancient lakes. Formed ∼4 million years ago, the lake harbours many coastal species that commonly inhabit seashores. The beach pea Lathyrus japonicus is a typical coastal species of this freshwater lake, but its inland populations are faced with the threat of extinction. Here, we investigated the phylogeographical and population structures ...
