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

Medicago LINC complexes function in nuclear morphology, nuclear movement, and root nodule symbiosis 1[OPEN] [PDF]

open access: yes, 2018
Nuclear movement is involved in cellular and developmental processes across eukaryotic life, often driven by Linker of Nucleoskeleton and Cytoskeleton (LINC) complexes, which bridge the nuclear envelope (NE) via the interaction of Klarsicht/ ANC-1/Syne-1

Quantification of mycorrhizal limitation in beech spread [PDF]

open access: yes, 2012
Establishment of Nothofagus spp. into grasslands can be limited by a lack of ectomycorrhizal inoculum, but the degree of mycorrhizal inoculum limitation and how far mycorrhizal inoculum spreads from forest edges has not been quantified.

Shifting body weight-fecundity relationship in a capital breeder : maternal effects on egg numbers of the autumnal moth under field conditions [PDF]

open access: yes, 2013
In the literature, various environmental factors are described as being capable of influencing the reproductive output of insect females irrespective of their body size. Still, female body size or weight is widely used as a proxy for fecundity.

Floral structure and systematics in four orders of rosids, including a broad survey of floral mucilage cells [PDF]

open access: yes, 2018
Phylogenetic studies have greatly impacted upon the circumscription of taxa within the rosid clade, resulting in novel relationships at all systematic levels. In many cases the floral structure of these taxa has never been compared, and in some families,
