Analysis of chromosomal rearrangements after replication restart

, 2014
Impediments to DNA replication are known to induce gross chromosomal rearrangements (GCRs) and copy-number variations (CNVs). GCRs and CNVs underlie human genomic disorders and are a feature of cancer. During cancer development, environmental factors and

An assessment of chromosomal rearrangements in neopolyploids of Lilium hybrids

, 2010
Two types of newly induced polyploids (neopolyploids) of Lilium hybrids were monitored for the occurrence of chromosomal rearrangements through genomic in situ hybridization (GISH) technique.

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment

The Anatomical Record, EarlyView.
Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Male reproductive system in stenopodidean shrimps: Unveiling basal reproductive traits in shrimp‐like Pleocyemata (Stenopodidae and Spongicolidae)

The Anatomical Record, EarlyView.
Abstract Stenopodidea represents one of the basal lineages within Pleocyemata, yet the male reproductive system (MRS) of this group remains poorly understood, with limited information available regarding its morphology and function. This study provides the first detailed description of the MRS in four stenopodidean shrimp species from two families ...

Structural rearrangements as a recurrent pathogenic mechanism for SETBP1 haploinsufficiency

Human Genomics
Chromosomal structural rearrangements consist of anomalies in genomic architecture that may or may not be associated with genetic material gain and loss.

Bridging micro and macroevolution: insights from chromosomal dynamics in plants

Frontiers in Plant Science
Understanding the relationship between macro- and microevolutionary processes and their delimitation remains a challenge. This review focuses on the role of chromosomal rearrangements in plant population differentiation and lineage diversification ...

Chromothripsis and beyond: rapid genome evolution from complex chromosomal rearrangements

Genes & Development, 2013
Recent genome sequencing studies have identified several classes of complex genomic rearrangements that appear to be derived from a single catastrophic event rather than numerous incremental steps. In this review, Zhang et al.

The Genetic Of Mental Retardation [PDF]

, 2005
Mental retardation is a common problem with major implications for a nation’s health, education and community services. The causes of mental retardation have been found to have a definite etiological basis, which may be biochemical, chromosomal ...

Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak

Animal Research and One Health, EarlyView.
Genetic diversity, adaptation, wild introgression, and coat color mutation of golden yak from two populations on the Qinghai‐Xizang Plateau. ABSTRACT The golden yak lives on the Qinghai‐Xizang Plateau with a golden coat and adapts to high altitudes and strong ultraviolet environment. The golden coat is a prominent phenotype in many domesticated species,

Comparative Chromosome Painting Clarifies the Intraspecific Chromosomal Variation in Two Ctenomys Species (Rodentia: Ctenomyidae)

Animals
Background: Ctenomys is a subterranean rodent genus known for exhibiting the highest levels of chromosome variation, both among species (2n = 10 to 70) and within species.
