Imaging of Molecular and Developmental Responses to Abiotic Stresses in Reproductive Tissues

Physiologia Plantarum, Volume 178, Issue 1, January/February 2026.
ABSTRACT Abiotic stresses, such as drought, salinity, and extreme temperatures, have profound effects on plant reproduction, often leading to reduced fertility and yield. Reproduction in plants involves complex interactions between diverse cells, necessitating spatiotemporal resolution to understand how stress impacts each component of this intricate ...

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

Biologia 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 ...

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 ...
