Divisispiculimermis mirus n. gen., n. sp., a mermithid parasitizing larvae of Chironomus sp. in the Cajón o Grande Stream, Córdoba, Argentina, is described. The new genus differs from all other mermithid genera in having paired spicules which are separated and divided into proximal and distal sectors. The other diagnostic characters of the genus are medium size, nematodes with the cuticle appea...

In 2012, cancer genomics saw the addition of a new phrase to its lexicon: kataegis, Greek for thunderstorm and an apt description for the discovery of localized regions of hypermutation that were revealed when numerous breast cancer genomes were sequenced in a landmark study in Cell. Michael Stratton from the Wellcome Trust Sanger Institute, UK, and fellow co-authors of the study speculated tha...

Weeds not only cause yield and quality losses in cultivated plants but also hinder harvesting. To effectively reduce these negative effects, it's crucial to identify the weed species choose most appropriate control method. Conducting regular surveys areas where crops are grown is essential for this purpose. This study was carried out determine types, densities, frequency of occurrence barley, w...

Allopolyploidization (hybridization and whole-genome duplication) is a common phenomenon in plant evolution with immediate saltational effects on genome structure and gene expression. New technologies have allowed rapid progress over the past decade in our understanding of the consequences of allopolyploidy. A major question, raised by early pioneer of this field Leslie Gottlieb, concerned the ...

Polyploidy, or whole genome duplication, has played a major role in the evolution of many eukaryotic lineages. Although the prevalence of polyploidy in plants is well documented, the molecular and cytological consequences are understood largely from newly formed polyploids (neopolyploids) that have been grown experimentally. Classical cytological and molecular cytogenetic studies both have show...
