Finding the sweet spot: An exploration of environmental factors to optimize Ulva carbohydrate content and composition

open access: yesJournal of Phycology, EarlyView.
Abstract Green macroalgae from the Ulva genus are rich in polysaccharides of interest, including ulvan, starch, and cellulose. However, their content and structure are impacted by environmental factors, which poses challenges for industrial applications, especially in the context of climate change.

The host range paradox of Meloidogyne incognita: a physiological and transcriptomic analysis of nine susceptible interactions across six plant orders

open access: yesNew Phytologist, EarlyView.
Phylogenetic distance of host does not explain phenotypic differences of Meloidogyne incognita parasitism at 25 dpi. Summary The plant–parasitic nematode Meloidogyne incognita is the pathogen with the broadest host range among all known biotrophic interactions.

A Century of Understanding and Harnessing Heterosis

open access: yesPlant Breeding, EarlyView.
ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Observations on the Burrow Structures and Larval Behavior of Ephoron shigae (Takahashi, 1924) (Ephemeroptera: Polymitarcyidae) in River Sediments

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT The larvae of the mayfly Ephoron shigae (Takahashi, 1924) (Ephemeroptera: Polymitarcyidae) inhabit distinctive U‐shaped burrows in river and lake sediments, yet their ecology remains poorly documented. Using newly developed mechatronic technology, we obtained continuous observations that revealed new aspects of larval behavior.

Identification of apomixis in the Kentucky bluegrass (Poa pratensis L.) using auxin test

open access: yesActa Societatis Botanicorum Poloniae, 2012
The effect of auxin treatment on the formation of apomictic – endospermless grains in Poa pratensis was investigated in the study. Four Polish cultivars: Skiz, Eska 46, Alicja, Ani as well as six breeding lines: POB 13, SK-W-33, SKW-15, SKW-35A, SK-W-35A

Parental species and hybrid descendants of Bacillus (Insecta Phasmatodea) show different patterns of highly amplified, colocalized ribosomal and telomeric sequences

open access: yesThe European Zoological Journal, 2020
We investigated by dual-color fluorescence in situ hybridization (FISH) with 28S ribosomal and (TTAGG)n telomeric probes all species of the circum-Mediterranean genus Bacillus encompassing bisexual and parthenogenetic taxa, namely the three parental ...

Aphid Resistance in Pulse Crops: Sources, Mechanisms, Genetics and Breeding

open access: yesLegume Science, Volume 8, Issue 4, December 2026.
ABSTRACT Aphids are major pests of pulse crops, causing damage through phloem sap feeding and virus transmission. In this context, resistant varieties are central components of sustainable aphid management. This review synthesizes current knowledge on resistance sources, phenotyping strategies, resistance mechanisms, genetic control and breeding ...
