A single evolutionary innovation drives the deep evolution of symbiotic N2-fixation in angiosperms [PDF]

open access: yes, 2014
Symbiotic associations occur in every habitat on earth, but we know very little about their evolutionary histories. Current models of trait evolution cannot adequately reconstruct the deep history of symbiotic innovation, because they assume homogenous ...

Molecular phylogenetics of Limonium and related genera (Plumbaginaceae): biogeographical and systematic implications [PDF]

open access: yes, 2005
Phylogenetic relationships within Limonium (Plumbaginaceae) are evaluated using sequence data from three plastid regions (rbcL, the trnL intron, and the trnL-trnF intergenic spacer).

A nitrogénkötő szimbiózis génjeinek evolúciós és funkcionális vizsgálata Medicago truncatula modellnövényen [PDF]

open access: yes, 2018
Soil nutrient availability is a major limiting factor in plant growth and productivity at many areas under agricultural cultivation. An evolutionary answer to this demand is the symbiotic association of plants with soil microbes that provide valuable ...

Pollinator Diversity and Foraging Dynamics on Monsoon Crop of Cucurbits in a Traditional Landscape of South Indian West Coast [PDF]

open access: yes, 2017
Studies on insect pollinator ecology and dynamics are very rarely carried out in traditional Indian agriculture landscapes. Indiscriminate landscape changes in the rural areas and tendencies towards crop monocultures can have significant effects on ...

Phylogenetics of Flowering Plants Based on Combined Analysis of Plastid atpB and rbcL Gene Sequences [PDF]

open access: yes, 2017
Following (1) the large-scale molecular phylogeny of seed plants based on plastid rbcL gene sequences (published in 1993 by Chase et al., Ann. Missouri Bot. Gard.

Genome characteristics of facultatively symbiotic Frankia sp. strains reflect host range and host plant biogeography [PDF]

open access: yes, 2007
Soil bacteria that also form mutualistic symbioses in plants encounter two major levels of selection. One occurs during adaptation to and survival in soil, and the other occurs in concert with host plant speciation and adaptation. Actinobacteria from the

Morphology and angiosperm systematics in the molecular era [PDF]

open access: yes, 2018
Several ways in which morphology is used in systematic and evolutionary research in angiosperms are shown and illustrated with examples: 1) searches for special structural similarities, which can be used to find hints for hitherto unrecognized ...

Synorganisation without organ fusion in the flowers of Geranium robertianum (Geraniaceae) and its not so trivial obdiplostemony [PDF]

open access: yes, 2017
Background and Aims Synorganisation of floral organs, an important means in angiosperm flower evolution, is mostly realized by congenital or post-genital organ fusion.
