[EN] Background: For in vitro culture of plant and animal cells, one of the critical steps is to adjust the initial cell density. A typical example of this is isolated microspore culture, where specific cell densities ...

[EN] The aim of this project is to develop an analysis protocol for the study of growth dynamics of bacterial populations. This method will allow to identify and quantify the subpopulations that differentiate in the culture. ...

Induction of secondary embryogenesis on transformed androgenic microspore-derived embryos (MDEs) is a convenient approach to avoid chimerism and hemizygosis for the introduced transgene. In this work, we improved two aspects ...

[ES] El cáncer no es únicamente un proceso celular intrínseco que afecta a las células neoplásicas impulsado por una serie de errores genéticos y epigenéticos, sino que también depende de cambios en su entorno. El microambiente ...

[EN] Silverleaf nightshade (Solanum elaeagnifolium Cav.) is a drought tolerant invasive weed native to the New World. Despite its interest for common eggplant (S. melongena L.) breeding, up to now no success has been ...

[EN] Although it is widely accepted that osmolality and ion fluxes are the main factors triggering sperm motility in fish, a complex universal mechanism for sperm motility activation does not exist in fish, and studies of ...

Survival of polyploids in nature depends on several factors, including competition from diploid relatives and increased genetic diversity. Unlike other reported Centaurea polyploid complexes, diploid Centaurea aspera ...

[EN] The role of potassium from the seminal plasma and/or the activation media was examined by selectively removing from this media, and by testing the use of channel inhibitors and a K-ionophore. Sperm motility was measured ...

[EN] The role of seminal plasma sodium and activation media sodium on sperm motility was examined by selectively removing the element from these two media, in European eel sperm. Sperm size (sperm head area) was also ...
