Multi‐Level Approaches for Assessing Molecular and Physiological Traits of Drought and Heat Stress Tolerance in Plant Reproductive Development

Physiologia Plantarum, Volume 178, Issue 1, January/February 2026.
ABSTRACT Abiotic stress, particularly heat and drought, significantly impacts plant reproductive development, threatening crop productivity and food security. Understanding stress tolerance mechanisms requires a multi‐level approach that integrates physiological, biochemical, and molecular traits in different experimental settings. This review explores

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 ...

The carnivorous rainbow plant Byblis filifolia Planch. secretes digestive enzymes in response to prey capture independently of jasmonates

Plant Biology, Volume 27, Issue 4, Page 549-557, June 2025.
Secretion of digestive enzymes in response to prey capture in carnivorous plants with sticky traps is regulated by jasmonates in Drosera capensis but differently by unknown factor in Byblis filifolia. Abstract Carnivorous plants from the order Caryophyllales co‐opted plant phytohormones from a group of jasmonates to regulate digestive enzyme activity ...

Normal microspore production after cell fusion in Brachiaria jubata (Gramineae)

Genetics and Molecular Biology, 2003
Cytogenetic studies were carried out on 22 accessions of Brachiaria jubata from the Embrapa Beef Cattle Brachiaria collection. One accession was diploid (2n = 2x = 18) and the remaining 21 were tetraploid (2n = 4x = 36). Among five tetraploid accessions,
