Identification of suitable reference genes for studying gene expression in cucumber plants subjected to abiotic stress and growth regulators
M. Migocka,A. Papierniak +1 more
TL;DR: The authors of this study assume that the novel cucumber reference genes determined will enable better normalization and quantification of transcript levels in future expression studies on cucumber plants.
Book ChapterDOI
Cucumber: Cucumis sativus L.
TL;DR: The use of this vegetable is highlighted and its cytology, genetics, germplasm resources, and reproductive biology are reviewed and techniques applicable to the improvement of cucumber are described.

Balancing selection in species with separate sexes: insights from fisher's geometric model
Tim Connallon,Andrew G. Clark +1 more
TL;DR: It is shown that balancing selection is common under biologically plausible conditions and that sex differences in selection or sex-by-genotype effects of mutations can each increase opportunities for balancing selection.

Next‐generation sequencing, FISH mapping and synteny‐based modeling reveal mechanisms of decreasing dysploidy in Cucumis
Luming Yang,Dal-Hoe Koo,Da-Wei Li,Da-Wei Li,Tao Zhang,Jiming Jiang,Feishi Luan,Susanne S. Renner,Elizabeth Henaff,Walter Sanseverino,Jordi Garcia-Mas,Josep M. Casacuberta,Douglas Senalik,Douglas Senalik,Philipp W. Simon,Philipp W. Simon,Jinfeng Chen,Yiqun Weng,Yiqun Weng +18 more
TL;DR: A fine-scale understanding of the mechanisms of dysploid chromosome reduction that has not been achieved previously is allowed to be achieved.
Journal ArticleDOI
Centromere repositioning in cucurbit species: Implication of the genomic impact from centromere activation and inactivation
TL;DR: Both centromere activation and inactivation in cucurbit species were associated with a gain/loss of a large amount of pericentromeric heterochromatin.

Über die Ubiquität der SAT-chromosomen bei den Blütenpflanzen
TL;DR: Nachdem 1873, 1875 and 1882 SCHNEIDER, STRASBVRGER, BtiTSCHLI and FLEMMING die kleinen bei den Kernteilungen auftretenden St~bchen gefunden hatten, beobachtete S. NAWASCHIN 1912 bei zwei untersuchten Arten einiger Chromosomen kleine K5rperchen,

Cytological and Phylogenetic Studies in the Cucurbitaceae
TL;DR: The results of an experimental study of the fertility relations involving 4 genera and 8 species of the Cucurbitaceae indicate that species crossing is comparatively rare and not at all in accord with popular beliefs.

A Technic for Differential Staining of Nucleoli and Chromosomes
C. S. Semmens,P. N. Bhaduri +1 more
TL;DR: A procedure is described which enables a stain to be definitely located in the substance of the nucleolus, with magenta chromatin and well defined green nucleoli.
