Adaptation to high ethanol reveals complex evolutionary pathways [PDF]

open access: yes, 2015
Tolerance to high levels of ethanol is an ecologically and industrially relevant phenotype of microbes, but the molecular mechanisms underlying this complex trait remain largely unknown.

The evolution of haploidy and diploidy [PDF]

open access: yesCurrent Biology, 2008
It is remarkable that one of the most fundamental features of an organism — its ploidy level — is so variable among taxa, with life cycles running the entire gamut from complete haploid dominance to complete diploid dominance. Theoretical studies have clarified many important genetic advantages to haploidy (for example, lower mutation load, more rapid ...

A century of theories of balancing selection

open access: yesBiological Reviews, Volume 101, Issue 2, Page 804-825, April 2026.
ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

First case of near haploid philadelphia negative B-Cell acute lymphoblastic leukaemia relapsing as acute myeloid leukemia following allogeneic hematopoietic stem cell transplantation

open access: yesLeukemia Research Reports, 2020
Herein we present a female patient aged 61 with Philadelphia negative acute lymphoblastic leukaemia demonstrating near haploid karyotype and abnormal TP53 expression at diagnosis, who relapsed with lineage switch as Acute Monocytic Leukemia post ...

Doubled haploid ramets via embryogenesis of haploid tissue cultures [PDF]

open access: yes, 2010
Tissue culture in the oil palm business is generally concerned with the multiplication (clonal production) of dura, pisifera and tenera palms. These are all normal diploids (2n=2x=36).

Genome Sequence and Population Genomic Analysis of Cronartium quercuum f.sp. fusiforme

open access: yesForest Pathology, Volume 56, Issue 1, February 2026.
ABSTRACT Fusiform rust, caused by Cronartium quercuum f. sp. fusiforme (Cqf), is the most severe disease of planted southern pines in the south‐eastern United States. Despite the critical role pathogen genomics play in disease outcomes, the population structure and genetic variability of Cqf remain poorly characterised.

Derivation of Mouse Haploid Trophoblast Stem Cells

open access: yesCell Reports, 2019
Summary: Trophoblast stem (TS) cells are increasingly used as a model system for studying placentation and placental disorders. However, practical limitations of genetic manipulation have posed challenges for genetic analysis using TS cells.

Genetic Gains in Durum Wheat (Triticum turgidum ssp. durum) Across the Globe: Yield, Quality and Adapting for Variable Weather Patterns

open access: yesPlant Breeding, Volume 145, Issue 1, Page 142-165, February 2026.
ABSTRACT Durum wheat (Triticum turgidum ssp. durum [Desf.] Husnot) is cultivated globally and used to produce pasta, couscous, bulgur and other semolina products. With the growing world population and increasing food demand, it is pertinent to understand past trends in global food production to shape future endeavours.
