Cytoembryological aspects of reduced seed setting in Ranunculus ficaria L. subsp. bulbifer (Marsden-Jones) Lawalrée

open access: yesActa Societatis Botanicorum Poloniae, 2014
Highly disturbed micro- and macro-sporogenesis in R. ficaria L. subsp. bulbifer gives rise to cytologically and genetically unbalanced reproductive cells. In plants from different papulatians, pollen degenerates in various percentages.

The role of plant hormones on the reproductive success of red and brown algae

open access: yesFrontiers in Plant Science, 2022
Seaweeds or macroalgae are important primary producers that serve as a habitat for functioning ecosystems. A sustainable production of macroalgae has been maintained by a diverse range of life cycles.

The phase change in ferns

open access: yesActa Societatis Botanicorum Poloniae, 2014
It is argued that the phasic alternation of sporophyte and gametophyte in ferns involves changing gene activation during oogenesis and sporogenesis respectively.

Deciphering the soybean root rot pathogen Phytophthora sojae: Signaling pathways, transcriptional regulation, and effector biology

open access: yesNew Plant Protection, Volume 3, Issue 2, June 2026.
This review highlights how Phytophthora sojae utilizes unconventional lineage‐specific signaling networks, including unique G protein‐coupled receptor fusions, expanded kinases, and rapidly evolving effectors, to infect soybeans. Understanding these divergent molecular paradigms reveals critical vulnerabilities in this destructive pathogen, offering ...

Rapid Clearance of Tetracapsuloides bryosalmonae Spores by Freshwater Sponge Ephydatia muelleri: Potential Implications for Controlling Proliferative Kidney Disease in Salmonids

open access: yesJournal of Fish Diseases, Volume 49, Issue 6, June 2026.
ABSTRACT Host–parasite interactions are influenced by both abiotic and biotic factors. While abiotic drivers, particularly temperature, have received considerable attention in recent years due to global climate change, the role of biotic factors remains comparatively underexplored.

VPS13 has an important role in female germline development in Arabidopsis

open access: yesThe Plant Journal, Volume 126, Issue 3, May 2026.
SUMMARY The female germline precursor cell, known as the megaspore mother cell (MMC), differentiates and develops within the ovule through a complex genetic network, including post‐transcriptional and translational regulation mediated by miRNA. A key player in restricting MMC development to a single cell within the nucellus is the AUXIN RESPONSE FACTOR
