Karyotype, ploidy, and gene dosage [PDF]

WormBook, 2005
The normal karyotype of Caenorhabditis elegans, with its five pairs of autosomes and single pair of X chromosomes, is described. General features of chromosomes and global differences between different chromosomal regions are discussed. Abnormal karyotypes, including duplications, deficiencies, inversions, translocations and chromosome fusions are ...

CHROMOSOMES OF TWO OLYRA L. SPECIES FROM MISIONES, ARGENTINA (POACEAE, BAMBUSOIDEAE, OLYREAE) [PDF]

BAG. Journal of Basic and Applied Genetics, 2022
The subfamily Bambusoideae comprises three monophyletic tribes, Arundinarieae, Bambuseae and Olyreae. Here we report the gametic number and the chromosomal meiotic behavior of two species belonging to the herbaceous tribe Olyreae, Olyra latifolia and ...

Dynamic genome plasticity during unisexual reproduction in the human fungal pathogen Cryptococcus deneoformans.

PLoS Genetics, 2021
Genome copy number variation occurs during each mitotic and meiotic cycle and it is crucial for organisms to maintain their natural ploidy. Defects in ploidy transitions can lead to chromosome instability, which is a hallmark of cancer.

Fingerprint Analysis of Volatile Flavor Compounds in Crassostrea gigas of Different Ploidy and Gender under High-Temperature Incubation

Molecules, 2023
In this study, diploid, triploid, and tetraploid Crassostrea gigas samples were subjected to gas chromatography and ion mobility (GC-IMS) to identify and analyze volatile compounds and flavor fingerprints under conditions of high-temperature incubation ...

Comparative Study on Pollen Viability of Camellia oleifera at Four Ploidy Levels

Agronomy, 2022
Oil tea (Camellia oleifera Abel.) is one of the most important woody edible oil tree species in China, with intraspecific polyploid. In order to study the variation in pollen size and vigor of C. oleifera at ploidy level, four ploidy covers a total of 32

Differential Requirement for the Cell Wall Integrity Sensor Wsc1p in Diploids Versus Haploids

Journal of Fungi, 2021
The primary role of the Cell Wall Integrity Pathway (CWI) in Saccharomyces cerevisiae is monitoring the state of the cell wall in response to general life cycle stresses (growth and mating) and imposed stresses (temperature changes and chemicals). Of the

Estimation of Genome Size in the Endemic Species Reseda pentagyna and the Locally Rare Species Reseda lutea Using comparative Analyses of Flow Cytometry and K-Mer Approaches

Plants, 2021
Genome size is one of the fundamental cytogenetic features of a species, which is critical for the design and initiation of any genome sequencing projects and can provide essential insights in studying taxonomy, cytogenetics, phylogenesis, and ...
