Oregon Wolfe barley genetic stocks – Research and teaching tools for next generation scientists

open access: yesJournal 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.

open access: yesNew 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 ...

Effects of endogamy on microsporogenesis in popcorn (Zea mays L.) [PDF]

open access: yesCrop Breeding and Applied Biotechnology, 2007
Inbred lines are necessary for the development of popcorn hybrids. Genes for several traits, among them thoserelated to the meiotic process, approach homozygosis during inbreeding. The purpose of this paper was to evaluate themeiotic stability of popcorn

Genome‐wide association study identifies QTL and candidate genes for grain size and weight in a Triticum turgidum collection

open access: yesThe 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 ...

Interspecific somatic hybrids between Solanum bulbocastanum and S. tuberosum and their haploidization for potato breeding

open access: yesBiologia Plantarum, 2012
Protoplast fusion between incongruent Solanum bulbocastanum and S. tuberosum haploids was accomplished to produce hybrids combining elite traits from both parents. We identified 11 somatic hybrids out of 42 regenerants analyzed through ISSR markers. Some

Patterns and Drivers of Pollen Temperature Tolerance

open access: yesPlant, Cell &Environment, Volume 48, Issue 2, Page 1366-1379, February 2025.
ABSTRACT Pollen, a pivotal stage in the plant reproductive cycle, is highly sensitive to temperature fluctuations, impacting seed quality and quantity. While the importance of understanding pollen temperature limits (Tmin, Topt, Tmax – collectively PTLs) is recognized, a comprehensive synthesis of underlying drivers is lacking.

The role of spherosome-like vesicles in formation of cytomictic channels between tobacco microsporocytes

open access: yesBiologia Plantarum, 2013
The formation of cytomictic channels (CCs) during the tobacco microsporogenesis has been analyzed by microscopy and cytochemical methods. Starting from the pachytene stage, CCs were formed between microsporocytes with involvement of specific organelles ...

Impacts of higher daytime temperatures on viable pollen and fruit production in common Cerrado tree Byrsonima pachyphylla (Malpighiaceae)

open access: yesBiotropica, Volume 56, Issue 5, September 2024.
Temperatures in the Brazilian Cerrado—an important, complex, and biodiverse savannah ecosystem–are increasing, potentially impacting many aspects of plant development and function, including sexual reproduction, which is thought to be particularly sensitive to temperature stress.

Chemical mutagenesis in head cabbage (Brassica oleracea var.capitata L.): III effect of ethyl methane sulphonate on mycosporogenesis and pollen fertility [PDF]

open access: yesSelekcija i Semenarstvo, 2006
The aim of present investigation was to study the effect of different ethyl methane sulfonate (EMS) concentrations (0.5, 0.6 and 0.7%) on microsporogenesis and on the expression of pollen fertility in M1 plants, obtained from treated cabbage seeds ...
