Oregon Wolfe barley genetic stocks – Research and teaching tools for next generation scientists
Journal of Plant Registrations, Volume 19, Issue 3, September/December 2025.Abstract The Oregon Wolfe Barley (OWB) mapping population (Reg. no. MP‐4, NSL 554937 MAP) is a resource for genetics research and instruction. The OWBs are a set of doubled haploid barley (Hordeum vulgare L.) lines developed at Oregon State University from the F1 of a cross between Dr. Robert Wolfe's dominant and recessive marker stocks.

Dynamic patterns of repeats and retrotransposons in the centromeres of Humulus lupulus L.
New Phytologist, Volume 247, Issue 6, Page 2766-2780, September 2025.Summary The centromere has a conserved function across eukaryotes; however, the associated DNA sequences exhibit remarkable diversity in both size and structure. In plants, some species possess well‐defined centromeres dominated by tandem satellite repeats and centromeric retrotransposons, while others have centromeric regions composed almost entirely ...

Microsporogenesis and pollen formation in cassava
Biologia Plantarum, 2011 This article describes the complete microsporogenesis and pollen formation in cassava (Manihot esculenta Crantz) at the various developmental stages (pollen mother cell, meiosis, tetrads, early free spore, mid uninucleate, late uninucleate, binucleate ...

The Plant Genome, Volume 18, Issue 1, March 2025.Abstract Wheat breeders are constantly looking for genes and alleles that increase grain yield. One key strategy is finding new genetic resources in the wild and domesticated gene pools of related species with genes affecting grain size. This study explored a natural population of Triticum turgidum (L.) phenotyped for grain weight and size‐related ...

Cytoplasniic differentiation during microsporogenesis in higher plants
Acta Societatis Botanicorum Poloniae, 2014 Conspicuous cytoplasmic dedifferentiation in the pollen mother cells takes place early in the meiotic prophase of many plants. This event involves the removal of much of the cytoplasmic RNA.
