A Century of Understanding and Harnessing Heterosis

open access: yesPlant Breeding, EarlyView.
ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Induced artificial androgenesis in common tench, Tinca tinca (L.), using common carp and common bream eggs

open access: yesItalian Journal of Animal Science, 2014
This study presents artificial induction using tench eggs, Tinca tinca (L.), of androgenetic origin. The oocytes taken from common bream, Abramis brama (L.) and common carp, Cyprinus carpio L.

Effects of Antimitotic Agents, Temperature and Immersion Time on Chromosome Doubling Efficiency in Supersweet Corn (Zea mays L. var. saccharata)

open access: yesPlant Breeding, EarlyView.
ABSTRACT Doubled haploid technology accelerates the development of fully homozygous maize lines compared with conventional selfing. However, specific protocols for supersweet corn (Zea mays L. var. saccharata), particularly regarding immersion time in antimitotic solutions and temperature during chromosome doubling, remain poorly defined.

Genomic Selection for Haploid Induction Rate in Tropical Maize (Zea mays L.) Haploid Inducer Populations: Insights From Heterotic Pools and Recurrent Selection Cycles

open access: yesPlant Breeding, EarlyView.
ABSTRACT Doubled‐haploid (DH) technology based on in vivo haploid induction has become an effective strategy for accelerating maize breeding. However, improving haploid inducer populations remains challenging because accurate estimation of haploid induction rate (HIR) requires labour‐intensive phenotypic validation, while putative HIR estimates are ...

Critical Windows of Air Pollution Exposure During Spermatogenesis and Intrauterine Insemination Outcomes

open access: yesPaediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Male preconception health remains a critically under‐addressed area of family planning. While research suggests air pollution may harm semen quality, downstream impacts on pregnancy, particularly for more vulnerable infertility treatment populations, are understudied.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Maternal Haploid Induction Through Egg Cell‐Specific Endopeptidases in Brassica napus: A Step Forward Towards Hybrid Fixation

open access: yesFood and Energy Security
Hybrid fixation is an emerging breeding tool that eliminates the need to purchase costly hybrid seeds on an annual basis. However, this technique is limited to Arabidopsis, rice, and soybean with a severe issue of seed setting.

Application of chosen factors in the wide crossing method for the production of oat doubled haploids

open access: yesOpen Life Sciences, 2015
Oat (Avena sativa L.) has recently gained importance due to the discovery of a variety of health benefits and new opportunities of use. There is no efficient protocol for the production of oat doubled haploid (DH) lines.

Advancing Thermotolerance in Beans: Integrating Physiology, Genomics, and Breeding for Climate Adaptation

open access: yesLegume Science, Volume 8, Issue 3, September 2026.
ABSTRACT Rising global temperatures increasingly threaten bean production and the food security of millions of people who depend on these protein‐rich legumes. Heat stress during the reproductive stages induces pollen sterility, flower abscission, and disruptions in source–sink relationships, resulting in yield losses of 30%–40% or more when critical ...

Optical mapping reveals a higher level of large‐scale structural variants in a family with paternally transmitted myotonic dystrophy and independent Parkinson's disease

open access: yesThe Journal of Pathology, Volume 270, Issue 1, Page 83-97, September 2026.
Abstract Myotonic dystrophy type 1 (DM1) is a clinically challenging multisystem neuromuscular hereditary disorder, with generational increase in severity and earlier age at onset. It is caused by an unstable cytosine‐thymine‐guanine repeat expansion at the DMPK locus, accompanied by associated genetic and epigenetic modifications.
