Morphological characterization and reproductive aspects in genetic variability studies of forage peanut

open access: yesScientia Agricola, 2003
Morphological characterization and the study of reproductive behavior are important procedures to identify desirable traits of progenitors to be included in breeding programs. Morphological descriptors and the reproductive behavior of parental accessions

The search for the best airborne pollen monitoring locations

open access: yes
In Europe a quarter of the adult population and a third of all children suffer from allergenic airborne pollen thereby decreasing the quality of life. In order to ease the pollen induced symptoms mitigation measures can be applied.

Watermelon genotype‐independent transformation via direct organogenesis from the cotyledon base

open access: yesJournal of Integrative Plant Biology, EarlyView.
Inducing adventitious buds from the base of watermelon cotyledon through direct organogenesis resulted in a watermelon genetic transformation system that overcomes regeneration barriers and genotype limitations.

Natural and anthropogenic forest fires recorded in the Holocene pollen record from a Jinchuan peat bog, northeastern China [PDF]

open access: yes, 2008
Pollen and charcoal particles from a Jinchuan peat (northeastern China) were examined to investigate the fire origin and interaction between climate, vegetation, fire and human activity during the Holocene.

Smart double‐screening system of propagating male‐sterile lines for maize hybrid seed production

open access: yesJournal of Integrative Plant Biology, EarlyView.
The Seed and Seedling Marker Method double‐screening system for maize hybrid seed production integrates Ms45‐mediated fertility restoration, Mn1/Sh1‐RNAi‐based seed selection, and Lc‐based seedling selection. It thus enables efficient, high‐purity propagation of male‐sterile lines by combining fertility maintenance with sequential visual selection at ...

A robust biotechnology induces artificial genomic duplication via transient RNAi‐mediated suppression of OSD1 in rice

open access: yesJournal of Integrative Plant Biology, EarlyView.
Plant Polyploidization via Gene Interference, a robust technology for inducing polyploidy in various rice accessions, uses transient RNAi‐mediated suppression of OSD1 to induce genomic duplication. Two strategies were used to directly induce fertile autotetraploid plants in the first generation, thereby substantially shortening the breeding cycle ...

Linking variation in genome size to cyst size in chrysophytes

open access: yesJournal of Phycology, EarlyView.
Abstract Genome size varies tremendously across eukaryotes, which often contain far more DNA than expected from their biological complexity. To explain this paradox, selection‐based hypotheses propose that genome size evolves through selection acting on life‐history traits correlated with the phenotypic effects, independent of its genic content.

Ecology and evolution of sterols in pollen and wild bees

open access: yes
Bees are reliant on flowers for their dietary intake of protein and fats. This includes sterols which act as essential membrane components and hormone precursors in insects.

Nanoparticles in Periodontology and Implant Dentistry: From Mechanisms to Clinical Applications

open access: yesJournal of Periodontal Research, EarlyView.
Nanotechnology holds significant promise in improving dental care, yet there is a need for more reliable clinical studies to validate its effectiveness and safety. ABSTRACT Recent advances in nanotechnology are reshaping the landscape of periodontology and implant dentistry, particularly through the application of nanoparticles (NPs).

The MexMAGIC population reveals the genetic architecture of traits exhibiting clinal variation in Mexican native maize

open access: yesNew Phytologist, EarlyView.
The MexMAGIC population mixes native maize varieties from across Mexico to study functional genetic diversity. Summary Defining the genetic basis of local adaptation is a key goal of evolutionary biology and crop improvement. Theory predicts that when selective pressures follow differences in the environment, a cline will be established.
