Efeitos de meios de cultura na formação de calos a partir de anteras de aspargo (Asparagus officinalis L.) Effects of the culture media on the calli formation from Asparagus officinalis L. anthers

Acta Botânica Brasílica, 1995
Técnicas auxiliares, como a cultura de anteras, possibilitam melhor eficiência na obtenção de novos genótipos de aspargo. Neste trabalho, foram utilizadas anteras contendo grãos de pólen, no estágio uninucleado, dos híbridos 56x22-8 e 47x22-8, em meio MS,

The mitochondrial DNA copy number and ovary‐related reproductive disorders: A bidirectional two‐sample Mendelian randomization study

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 112-120, April 2025.
Abstract Objective In the present study, a bidirectional two‐sample Mendelian randomization approach was utilized to explore potential causal relationships between mitochondrial DNA copy number (mtDNA‐CN) and ovary‐related reproductive disorders (ORRDs), including ovarian dysfunction, ovarian cyst, polycystic ovary syndrome (PCOS), premature ovarian ...

Polymorphic STRs represent unique genetic signals beyond SNPs associated with climate adaptation in Marchantia polymorpha

iMetaOmics, EarlyView.
Natural populations of Marchantia polymorpha sampled across contrasting climatic regions show clear geographic differentiation between Europe and Japan based on polymorphic short tandem repeat (STR) variation. Genome‐wide association (GWAS) analyses identified pSTR loci whose repeat‐length variation tracks temperature‐related WorldClim variables.

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

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 ...

Meiosis in haploid yeast [PDF]

Proceedings of the National Academy of Sciences, 1982
Haploid yeast cells normally contain either the MAT a or MAT α mating-type allele and cannot undergo meiosis and spore formation. If both mating-type alleles are present as a consequence of chromosome III disomy ( MAT

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.

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

Insect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.
