Occurrence of Ploidy Variation in Camellia ×vernalis

: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type

abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...

Ecogeography of ploidy variation in cultivated potato (Solanum sect. Petota).

UNLABELLED PREMISE OF THE STUDY The taxonomy of cultivated potatoes has been highly controversial, with estimates of species numbers ranging from 3 to 17. Ploidy level has been one of the most important taxonomic characters to recognize cultivated potato species, containing diploid (2n = 2x = 24), triploid (2n = 3x = 36), tetraploid (2n = 4x = 48), and pentaploid (2n = 5x = 60) cultivars. We...

Ploidy variation in multinucleate cells changes under stress

Ploidy variation is found in contexts as diverse as solid tumors, drug resistance in fungal infection, and normal development. Altering chromosome or genome copy number supports adaptation to fluctuating environments but is also associated with fitness defects attributed to protein imbalances. Both aneuploidy and polyploidy can arise from multinucleate states after failed cytokinesis or cell fu...

Diurnal variation in occurrence of strokes.

The time of onset of a completed stroke was recorded in 707 patients. Of the 554 cerebral infarctions 40% occurred between midnight and 6 a.m. Onset at night was, if anything, less common among the 153 cases of cerebral hemorrhage.
