Notulae Botanicae Horti Agrobotanici Cluj-NapocaIn this study, the mating system of the endangered aquatic fern Ceratopteris thalictroides in China was investigated using microsatellite markers. The estimates of the multilocus outcrossing rate (tm) and single-locus outcrossing rate (ts) were high at ...

Outcrossing rate of safflower (Carthamus tinctorius L.) genotypes under the agro climatic conditions of Northern Germany [PDF]
, 2008 Safflower oil is considered to be one of the highest quality vegetable oils for human nutrition, containing up to 90% linoleic acid. The cultivation of safflower would enlarge the number of species to increase biodiversity and widen crop rotation.

Local-scale patterns of genetic variability, outcrossing, and spatial structure in natural stands of Arabidopsis thaliana [PDF]
, 2015 As Arabidopsis thaliana is increasingly employed in evolutionary and ecological studies, it is essential to understand patterns of natural genetic variation and the forces that shape them.

Annals of Neurology, EarlyView.Objective Myotonic dystrophy type 1 (DM1) is a highly variable, multisystemic genetic disorder caused by a CTG repeat expansion in the 3′ untranslated region of DMPK. Toxicity is exerted by repeat‐containing DMPK transcripts that sequester muscleblind‐like (MBNL) proteins and lead to deleterious yet predictable changes in alternative splicing.

Agriculture, 2018 Male sterility enabled commercialization of heterosis in rice but low seed set remains a constraint on hybrid dissemination. We evaluated 216 F6 maintainer lines for agronomic and floral characteristics in augmented design and selected 15 maintainer ...

Nordic Journal of Botany, EarlyView.Pollen limitation, a decrease in seed production due to insufficient pollen receipt, may influence plant demography and the evolution of sexual systems. Its empirical estimation of pollen supplementation of some of the flowers on an individual is well known to be prone to overestimation due to potential resource reallocation among the individual's ...

Assessing the genetic structure of Oryza glumaepatula populations with isozyme markers
Brazilian Archives of Biology and Technology, 2008 To assess the genetic diversity and genetic structure parameters, nine populations of Oryza glumaepatula from the Amazon biome, four from the Pantanal biome, and one collected at Rio Xingu, Mato Grosso, totaling 14 populations and 333 individuals were ...

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales
Nordic Journal of Botany, EarlyView.Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Genetics and Molecular Biology, 2004 The mating system and genetic diversity were studied in a natural population of Myracrodruon urundeuva originating from 30 open-pollinated trees at the Paulo de Faria Ecological Station, SP, Brazil. The progenies were planted on the Teaching and Research
