Cytological analysis of mixoploidy of cell populations in apozygotic offsprings of haplid plants in sugar beets

Фактори експериментальної еволюції організмів, 2013
The goal of the paper was a cytological analysis of cells populations in the haploids plants of sugar beets. Methods. A primary selection of haploids seedlings from apozygotic seed samplings was made by the morpholological charfcters.

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

Plant 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 ...

Genome‐Wide Association Study Elucidates the Genetic Architecture of Manganese Tolerance in Brassica napus

Plant, Cell &Environment, EarlyView.
ABSTRACT Brassica napus (canola) is a significant contributor to the world's oil production and is cultivated across continents, yet acidic soils with aluminium (Al3+) and manganese (Mn2+) toxicities limit its production. The genetic determinants underlying natural variation for acidic soil tolerance in canola are unknown and need to be determined ...

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

Paediatric 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.

Through the Sands of Time: Evolutionary History and Systematics of the Awl‐Headed Snakes (Colubridae: Lytorhynchus) in the Saharo‐Sindian Region

Zoologica Scripta, EarlyView.
ABSTRACT The psammophilous colubrid genus Lytorhynchus is widely distributed in the deserts of the Saharo‐Sindian region and adjacent areas. The taxonomy of the genus and the number of recognised species have remained unstable since the last taxonomic revision in 1970, with differing views on the taxonomic status of L. gaddi and L. kennedyi.

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

Experimental 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 ...

Preliminary study documents variable accuracy and inclusion among biology instructor gender/sex definitions

Natural Sciences Education, Volume 55, Issue 2, December 2026.
Abstract Society generally presents sex inaccurately as a binary variable based on one or few trait(s), causing myriad issues, including the pursuit of reductionist biology experiments, the creation of laws that limit the rights of women, people with queer genders, and intersex folks, and greater student endorsement of gender stereotypes in ...

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

Legume 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 ...
