Transfer cells in Horneophyton lignieri illuminate the origin of vascular tissues in land plants

open access: yesNew Phytologist, Volume 249, Issue 6, Page 3149-3164, March 2026.
Summary Recent fossil discoveries and advances in plant phylogeny have renewed debate about the most recent common ancestor (MRCA) of land plants and the evolution of its fundamental organs and tissues. We re‐investigate the vascular system of Horneophyton lignieri, an exceptionally preserved Rhynie Chert fossil central to understanding early plant ...

A Fossil Record of Spores before Sporophytes

open access: yesDiversity
Because their resistant, sporopolleninous walls preserve a record of morphogenetic change during spore formation, fossil cryptospores provide a direct physical record of the evolution of sporogenesis during the algal–plant transition.

Spleen as an Alternative Tissue for Estimating Tetracapsuloides bryosalmonae Load, Prevalence and Its Relationship With Proliferative Kidney Disease in Brown Trout

open access: yesJournal of Fish Diseases, Volume 49, Issue 1, January 2026.
ABSTRACT Accurate pathogen detection is essential in fish health management and disease prevention. Pathogens often target different host tissues, and monitoring alternative target organs can provide important insights into disease progression. We evaluated the spleen as an alternative to the kidney for estimating the load and prevalence of the ...

The WOPR Protein Ros1 Is a Master Regulator of Sporogenesis and Late Effector Gene Expression in the Maize Pathogen Ustilago maydis.

open access: yesPLoS Pathogens, 2016
The biotrophic basidiomycete fungus Ustilago maydis causes smut disease in maize. Hallmarks of the disease are large tumors that develop on all aerial parts of the host in which dark pigmented teliospores are formed.

Comparative insights into molecular pathways influencing germline development in early‐divergent angiosperms

open access: yesThe Plant Journal, Volume 125, Issue 2, January 2026.
SUMMARY The molecular and genetic mechanisms regulating female germline development remain largely unknown in basal and early‐divergent angiosperms. This contrasts with recent progress in model eudicots such as Arabidopsis thaliana and monocots, such as rice, barley, and maize. In this study, we investigate the genetic pathway governing female germline

Supplementary notes to the biology of Cordyceps entomorrhiza (Dicks. ex Fr.) Link and the morphology of its conidial stages

open access: yesActa Mycologica, 2014
Cordyceps entomorrhiza develops on the larvae, pupae and adults on the ground beetles Carabus spp. (Coleoptera, Carabidae) and on the bugs (Heteroptera, Nabidae) ot the genera Himacerus Wolff et Nabis Latr. There are two forms of the conidial sporulation

A Review of the Control of Coccidiosis in Poultry Using Natural Additives, Focusing on Gut Health and Immunity

open access: yesAdvances in Agriculture, Volume 2026, Issue 1, 2026.
Coccidiosis is one of the most common diseases in the poultry industry worldwide (especially in broilers aged 3–6 weeks), causing significant economic losses to poultry farmers and governments every year. Conventional methods (anticoccidial chemical compounds) for the coccidiosis debarment and control always present challenges and disadvantages, such ...

Mutante espontâneo de Bacillus licheniformis bloqueado no estágio I da esporogênese, possuidor de metabolismo respiratório aumentado A spontaneous mutant of Bacillus licheniformis with increased respiratory metabolism, blocked in stage I of sporogenesis

open access: yesMemorias do Instituto Oswaldo Cruz, 1976
Um mutante espontâneo de Bacillus licheniformis, derivado da amostra esporogênica 2390, foi estudado com vistas ao reconhecimento do estágio da evolução para esporo em que o mesmo se encontrava bloqueado.

Impact of Hanks Kinase‐Dependent Phosphorylation of CodY on the Physiology and Virulence in Bacillus cereus

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
CodY is a global regulator whose phosphorylation at serine 215 by PrkC/YbdM alters its DNA binding, thereby modulating gene expression and impacting motility, biofilm formation, cytotoxicity, and pathogenicity in Bacillus cereus, suggesting a conserved regulatory mechanism in Firmicutes ABSTRACT CodY acts as a key regulatory protein involved in ...
