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

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 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.

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

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 ...

A procedure for Dex-induced gene transactivation in Arabidopsis ovules
Background Elucidating the genetic and molecular control of plant reproduction often requires the deployment of functional approaches based on reverse or forward genetic screens.

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 ...
