Characterization of three GLOBOSA-like MADS-box genes from maize: evidence for ancient paralogy in one class of floral homeotic B-function genes of grasses.
TLDR
Cloned cDNAs of three different GLO-like genes from maize, a distant relative of rice within the Poaceae family, indicate that one of these genes, named ZMM16, is orthologous to OSMADS2, and that the other two, ZMM18 and ZMM29, are probably orthologously toOSMADS4, which occurred probably after the split of the lineages that resulted in extant Liliaceae and Poaceae.

Maize MADS-Box Genes Galore
TLDR
The genes reported here are a rich ressource for further studies on the evolutionary dynamics of a complex gene family, the developmental genetics of maize, and a rational crop design employing developmental control genes as tools. Expand
Lessons learned from microsatellite development for nonmodel organisms using 454 pyrosequencing
TLDR
It is shown that depending on the species, a different amount of 454 pyrosequencing data might be required for successful identification of a sufficient number of microsatellite markers for ecological genetic studies. Expand
Quantifying dispersal and establishment limitation in a population of an epiphytic lichen.
TLDR
This study exemplifies that care has to be taken to adequately separate the effects of dispersal limitation from a limitation of establishment and demonstrated substantial dispersal from other than local sources. Expand
Population genetics of lichen-forming fungi – a review

  • 3 August 2010
TLDR
The literature available on the genetic structure of lichen fungi is reviewed to show general trends, and some fascinating examples are discussed, and directions for future research are pointed out. Expand
Lichen diversity in temperate montane forests is influenced by forest structure more than climate
Although the effect of forest management on lichens in temperate forests has been widely examined, little is known about the influence of management-related factors on their biodiversity relative toExpand
Conservation strategies for lichens: insights from population biology
TLDR
The population biology of selected lichens is reviewed, highlighting the link between landscape and lichen population dynamics and suggest strategies to efficiently protect lichen species and develop priorities for species conservation approaches. Expand
Identity and genetic structure of the photobiont of the epiphytic lichen Ramalina menziesii on three oak species in southern California.
TLDR
The goals were to identify the photobiont species and assess its genetic structure, and hypothesize that R. menziesii is locally adapted to the phorophyte species through habitat specialization in the algal partner of the symbiosis. Expand
Variogram Analysis of the Spatial Genetic Structure of Continuous Populations Using Multilocus Microsatellite Data
TLDR
Variogram-based analysis not only avoids bias due to the underestimation of population variance in the presence of spatial autocorrelation, but also provides estimates of population genetic diversity and the degree and extent of spatial genetic structure accounting for autoc orrelation. Expand
Epiphytic macrolichen communities along regional gradients in northern Norway
Abstract Question: What are the relative influences of human impact, macroclimate, geographic location and habitat related environmental differences on species composition of boreal epiphyticExpand
