Tetraploid development in the mouse [PDF]

Developmental Dynamics, 2003
AbstractSpontaneous duplication of the mammalian genome occurs in approximately 1% of fertilizations. Although one or more whole genome duplications are believed to have influenced vertebrate evolution, polyploidy of contemporary mammals is generally incompatible with normal development and function of all but a few tissues.

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

Insect Science, EarlyView.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

Transcriptome Profiling to Dissect the Role of Genome Duplication on Graft Compatibility Mechanisms in Watermelon

Biology, 2022
Watermelon (Citrullus lanatus) is a popular crop worldwide. Compared to diploid seeded watermelon, triploid seedless watermelon cultivars are in great demand. Grafting in triploid and tetraploid watermelon produces few seedlings.

Integrated high‐resolution copy number and histomolecular analysis of diffuse hemispheric glioma, H3 G34‐mutant reveals universal TP53 abnormalities

Brain Pathology, EarlyView.
This integrated high‐resolution copy number and histomolecular analysis of diffuse hemispheric glioma, H3 G34‐mutant expands the spectrum of associated genetic changes and underscores the presence of universal TP53 abnormalities at copy number, sequence, and protein expression level, with frequent yet largely unrecognized TP53 copy‐neutral loss of ...

Preferential Homologous Chromosome Pairing in a Tetraploid Intergeneric Somatic Hybrid (Citrus reticulata + Poncirus trifoliata) Revealed by Molecular Marker Inheritance

Frontiers in Plant Science, 2018
The creation of intergeneric somatic hybrids between Citrus and Poncirus is an efficient approach for citrus rootstock breeding, offering the possibility of combining beneficial traits from both genera into novel rootstock lineages. These somatic hybrids

Callus Induction on True Shallot Seed Explant Using a Combination of BA and 2,4-D

Ilmu Pertanian (Agricultural Science), 2018
BA and 2,4-D combination were commonly used for in vitro culture of Shallot (Allium cepa L. var agregatum 2n = 2x = 16) to induce callus, but there was no information for callus induction on shallot seed (TSS) explant.
