Experimental Evolution Reveals Interplay between Sch9 and Polyploid Stability in Yeast. [PDF]
Polyploidization has crucial impacts on the evolution of different eukaryotic lineages including fungi, plants and animals. Recent genome data suggest that, for many polyploidization events, all duplicated chromosomes are maintained and genome ...

Parthenocarpy and Self-Incompatibility in Mandarins
Citrus reproductive biology is complex. One of its characteristic features is parthenocarpy that enables seedless fruit production. Citrus parthenocarpy and self-incompatibility knowledge is only partial and sometimes discrepant.

ABSTRACT Genomic tools for traceability of wood products offer a powerful tool to support sustainable forestry, fight illegal logging, and improve conservation efforts. Traditional identification methods (e.g., wood anatomy, spectroscopy) are limited in resolution or scope, but genomic approaches can infer both species identity and geographic origin ...

Caspase 2 in mitotic catastrophe: The terminator of aneuploid and tetraploid cells
Mitotic catastrophe is an oncosuppressive mechanism that targets cells experiencing defective mitoses via the activation of specific cell cycle checkpoints, regulated cell death pathways and/or cell senescence.

Induction of gynogenesis by heterogenous sperm and cold shock treatment in Epinephelus fuscoguttatus
Gynogenesis is a chromosome set manipulation technique to accelerate inbred lines used for genomics analysis and genetic breeding. Groupers are hermaphroditic fish whereby they sexually mature as females and subsequently change sex to male. Production of

ABSTRACT Doubled haploid (DH) technology has been widely adopted in maize (Zea mays L.) breeding programs due to its ability to reduce breeding cycle time and optimize costs. Early ploidy identification is essential for maximizing the efficiency of DH production, particularly prior to chromosome doubling.

Ploidy analysis among Citrus mutants using leaf meristematic tissue
A promising method for preparing metaphase spread for counting the number of chromosomes from the emerging shoot tissue is described in this report. In the present study, we adopted enzymatic digestion of shoot tips to analyse the chromosome number. The

Unraveling the Molecular Mechanisms Underlying Spontaneous Multipolar Mitosis Through CIN‐seq
Multipolar mitosis, a hallmark of chromosomal instability (CIN), drives tumor heterogeneity but is challenging to study in live cells. Using CIN‐seq, a single‐cell multiomics method, we profiled rare CIN events and identified mechanisms associated with viable multipolar mitosis, including PTEN attenuation, Rho GTPase‐driven cytokinesis failure, and ...

TOP1α, UPF1, and TTG2 regulate seed size in a parental dosage-dependent manner.
Cues of maternal and paternal origins interact to control seed development, and the underlying molecular mechanisms are still far from clear. Here, we show that TOPOISOMERASE Iα (TOP1α), UP-FRAMESHIFT SUPPRESSOR 1 (UPF1), and TRANSPARENT TESTA GLABRA2 ...

Whole genome duplication (WGD) is a dramatic evolutionary event generating many new genes and which may play a role in survival through mass extinctions. Paddlefish and sturgeon are sister lineages that both show genomic evidence for ancient WGD.
