Genomic analysis of plant chromosomes based on meiotic pairing [PDF]
Biotemas, 2007 This review presents the principles and applications of classical genomic analysis, with emphasis on plant breeding. The main mathematical models used to estimate the preferential chromosome pairing in diploid or polyploid, interspecific or intergenera ...

Comparative Cytogenetics, 2014 Dioecy is relatively rare among plant species, and distinguishable sex chromosomes have been reported in few dioecious species. The multiple sex chromosome system (XX/XY1Y2) of Humulus japonicus Siebold et Zuccarini, 1846 differs from that of other ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated. Procedure We

Organisation of the plant genome in chromosomes [PDF]
The Plant Journal, 2011 SummaryThe plant genome is organized into chromosomes that provide the structure for the genetic linkage groups and allow faithful replication, transcription and transmission of the hereditary information. Genome sizes in plants are remarkably diverse, with a 2350‐fold range from 63 to 149 000 Mb, divided into n = 2 to n = approximately 600 chromosomes.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Quantum dots – a versatile tool in plant science?
Journal of Nanobiotechnology, 2006 An optically stable, novel class of fluorophores (quantum dots) for in situ hybridisation analysis was tested to investigate their signal stability and intensity in plant chromosome analyses.

The evolution of mini-chromosomes in the fungal genus Colletotrichum
mBio, 2023 Anthracnose diseases caused by Colletotrichum species are among the most common fungal diseases. These symptoms typically manifest as dark, sunken lesions on leaves, stems, and fruit. In China, mango anthracnose seriously affects fruit yield and quality.

Comparative Genomics of Plant Chromosomes [PDF]
The Plant Cell, 2000 Comparative genomics, the study of similarities and differences in structure and function of the hereditary information in different taxa, uses molecular tools to investigate notions that far preceded the discovery that DNA was the hereditary molecule.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
