Gene turnover in the common ancestor of all C4 grasses

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Effect of Propylparaben on In Vitro Maturation of Porcine Oocytes and Embryo Development

Environmental Toxicology, EarlyView.
ABSTRACT Parabens are synthetic chemicals that, due to their antibacterial and fungicidal effects, are widely used as preservatives in food, cosmetics, and personal care products, such as shampoos, hair conditioners, body creams, soaps, deodorants, makeup, wet wipes, lotions, female hygiene products, and vaginal lubricants. Several years ago, they were

Genomic evidence for intraspecific hybridization in a clonal and extremely halotolerant yeast

BMC Genomics, 2018
Background The black yeast Hortaea werneckii (Dothideomycetes, Ascomycota) is one of the most extremely halotolerant fungi, capable of growth at NaCl concentrations close to saturation. Although dothideomycetous fungi are typically haploid, the reference

Yeast Knockout Strain Collection: Driving Functional Genomics, Biotechnological Applications and Human Disease Research

Yeast, EarlyView.
ABSTRACT The knockout strain collection of Saccharomyces cerevisiae has served as a valuable resource for functional genomics and yeast‐based biotechnology studies. A comprehensive single‐gene knockout strain collection, covering nearly all non‐essential genes, together with complementary mutant collections for essential genes, including temperature ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Captive Breeding of the Chinese Alligator Reduces Inbreeding but Increases Genetic Load

Integrative Zoology, EarlyView.
Captive breeding of the Chinese alligator successfully reduced genomic inbreeding but increased the burden of deleterious mutations. Genomic analyses indicate that managing both genetic diversity and genetic load is essential for the long‐term conservation of this critically endangered species.

A Robust Framework for Maize Elite Line Genome Editing Through Enhanced HI-Edit via LbCas12a Activity Optimization. [PDF]

Plant Biotechnol J
ABSTRACT Haploid induction coupled with genome editing (HI‐Edit) enables direct modification of commercial crop varieties, bypassing the need for trait introgression or direct transformation of elite lines with CRISPR machinery. However, its widespread application has been constrained by low haploid editing rates (HER), the proportion of haploids ...

Tipping the Scales Using Cryopreservation: Modelling the Genetic Value and Management Potential of Integrated Cryopreservation for Threatened Ex‐Situ Pupfish Populations

Animal Conservation, EarlyView.
This graphical abstract depicts the number of additional fish that would be required to achieve 90% genetic diversity for endangered pupfish species housed in EAZA collections, with or without the use of cryopreserved material. ABSTRACT Zoos and aquaria must retain genetic diversity for the species they house if the populations are to remain viable ...

Sperm Head–Tail Coupling Apparatus Diversity and Common Themes Among Species

Andrology, EarlyView.
ABSTRACT Background A stable connection between the sperm head (containing the nucleus and acrosome) and tail (containing the axoneme, mitochondrial sheath, and periaxonemal structures) is critical for fertility. This connection is mediated by a series of nuclear, cytoplasmic, and centriole components that make up the head–tail coupling apparatus (HTCA)

Spatiotemporal Expression of ARRDC5 in Mammalian Spermatogenesis

Andrology, EarlyView.
ABSTRACT Background Spermiogenesis is the final phase of sperm development during which haploid round spermatids transform into specialized spermatozoa and occurs across distinct stages of sperm production in the seminiferous epithelium. Abnormalities in this process lead to malformations and an inability of sperm to fertilize eggs.
