A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Progestogen supplementation to prevent miscarriage: Evidence and controversies

International Journal of Gynecology &Obstetrics, Volume 174, Issue 1, Page 44-49, July 2026.
Abstract Progesterone plays a key role in the establishment and maintenance of pregnancy and its deficiency has been associated with early pregnancy loss. Progestogen supplementation has therefore been widely investigated as a preventive strategy against miscarriage, particularly in women with recurrent pregnancy loss or threatened miscarriage or after

Reticulate allopolyploidy and subsequent dysploidy drive evolution and diversification in the cotton family

Nature Communications
Polyploidy and subsequent post-polyploid diploidization (PPD) are key drivers of plant genome evolution, yet their contributions to evolutionary success remain debated.

Ecological and evolutionary implications of hybridization, polyploidy and apomixis in angiosperms

Botan‪ical Sciences
Hybridization, polyploidy, and apomixis are related to the diversification of angiosperms, generating complex taxonomic relationships between species. Despite the differences in the frequencies of these phenomena, apomixis, the asexual seed production ...

Integrated high‐resolution copy number and histomolecular analysis of diffuse hemispheric glioma, H3 G34‐mutant reveals universal TP53 abnormalities

Brain Pathology, Volume 36, Issue 4, July 2026.
This integrated high‐resolution copy number and histomolecular analysis of diffuse hemispheric glioma, H3 G34‐mutant expands the spectrum of associated genetic changes and underscores the presence of universal TP53 abnormalities at copy number, sequence, and protein expression level, with frequent yet largely unrecognized TP53 copy‐neutral loss of ...

Functional Characterisation of HAIRPLUS (NtHAP) Genes Involved in Trichome Development and Specialised Metabolism of Tobacco

Plant Biotechnology Journal, Volume 24, Issue 7, Page 4640-4655, July 2026.
ABSTRACT Plant glandular trichomes are specialised epidermal structures capable of synthesising, storing and secreting numerous varieties of secondary metabolites in different classes and are central to plant defence and the biosynthesis of high‐value metabolites.

Polyploidy in vertebrate ancestry: Ohno and beyond

, 2004
Over 30 years ago, Susumu Ohno proposed that two rounds of polyploidy occurred early in vertebrate evolution. We re-examine this proposal using three recent lines of evidence.

Hybridization, polyploidy, and evolutionary transitions between monoecy and dioecy in Bryonia (Cucurbitaceae) [PDF]

, 2008
Correns’s 1903 (Berichte der Deutschen Botanischen Gesellschaft 21: 133 – 147) crosses between a monoecious and a dioecious species of Bryonia revealed the simple Mendelian inheritance of dioecy and provided the first instance of an XY sex determination ...

Cells Dynamically Adapt Their Nuclear Volumes and Proliferation Rates During Single to Multicellular Transitions

Advanced Science, Volume 13, Issue 31, 4 June 2026.
It is currently not well understood how cells regulate basic properties, e.g., volume and mechanics within dense multicellular environments like tumors. Here, we show that different cell types of cancer and also normal cells largely decrease their nuclear and cellular volumes in emerging cell clusters and that this is partly driven by cell cycle shifts.
