EyeChrom and CCDBcurator: Visualizing chromosome count data from plants

Visualizing count data regressions using rootograms

We show how the rootogram – a graphical tool associated with the work of J. W. Tukey and originally used for assessing goodness of fit of univariate distributions – can help to diagnose and treat issues such as overdispersion and/or excess zeros in regression models for count data. Two empirical illustrations, from ethology and from public health, are included. The former employs a negative bin...

COUSINIA PAPILLOSA, A NEW SPECIES FROM EASTERN IRAN, INCLUDING CHROMOSOME COUNT AND PALYNOLOGICAL STUDIES

Cousinia papillosa (Asteraceae) from eastern Iran is described and illustrated as a new species. Differences between the new species and its closest relative, C. meshhedensis, are discussed. A map showing the distribution of the two species is given. The scanning electron micrography of the pollen grains shows obvious differences between the two species especially in the sculpturing of exine. T...

Seevolution: visualizing chromosome evolution

SUMMARY Genome evolution underpins all of biology, yet its principles can be difficult to communicate to the non-specialist. To facilitate broader understanding of genome evolution, we have designed an interactive 3D environment that enables visualization of diverse genome evolution processes. The system can intuitively and interactively animate mutation histories involving genome rearrangement...

Mosaic and partial monosomy of chromosome 21 in a case with low platelets count

Background Monosomy is defined as the presence of only one chromosome instead of two in humans. Partial monosomy occurs when only a portion of the chromosome is present in a single copy, while the rest has two copies. It can occur in unbalanced translocations or deletions. Case report In this report, a 6 years old girl was presented who was referred to the Pediatric Dep, Shahid Sadoughi Ho...
