We investigated whether cluster formation by noninvasive cells can be explained by a global attractive potential. Indices quantifying the persistence of migration in experimental conditions were compared to the same indexes computed from simulations with a density-based cellular automaton. The results indicate that the attractive potential hypothesis must(More)
One of the major limitations to plant growth and yield in acidic soils is the prevalence of soluble aluminum ions (Al(3+)) in the soil solution, which can irreversible damage the root apex cells. Nonetheless, many Al-tolerant species overcome Al toxicity and are well-adapted to acidic soils, being able to complete their life cycle under such stressful(More)
The objective of this study was to quantify the molecular diversity and to determine the genetic relationships among Secale spp. and among cultivars of Secale cereale using RAPDs, ISSRs and sequence analysis of six exons of ScMATE1 gene. Thirteen ryes (cultivated and wild) were genotyped using 21 RAPD and 16 ISSR primers. A total of 435 markers (242 RAPDs(More)
Endocrine disrupting compounds (EDCs) are capable of interfering with the endocrine system and are increasingly widespread in the aquatic environments. In the present study, zebrafish (Danio rerio) embryos and larvae were used to assess how EDCs may interfere with embryogenesis. Therefore, zebrafish embryos were exposed to 17α-ethinylestradiol (EE2: 0.4, 2,(More)
