FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Plagiothecium lucidum (Hook. f. & Wils.) Paris in tropical Africa
, 2000 Plagiothecium lucidum (Hook. f. & Wils.) Paris is confirmed as a new addition to the bryoflora of tropical Africa on the basis of two collections from the Bale Mountains in Ethiopia. The type material of Isopterygium integrifolium Bartr.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

, 1993 Central Africa was one of the first regions in the tropics, if not the first, for which a checklist of mosses was compiled. In 1940, Demaret published the "Prodrome des Bryophytes du Congo Belge et du Ruanda-Urundi", followed by a supplement in 1946.

Environmental and host plant effects on taxonomic and phylogenetic diversity of root fungal endophytes [PDF]
Nearly all plants are colonized by fungal endophytes, and a growing body of work shows that both environment and host species shape plant-associated fungal communities.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

, 1993 Neckera submacrocarpa may be recognized by the numerous paraphyllia to ca. 2 mm long, and distally rugose perichaetial leaves. According to De Sloover (1977), it occurs in montane forests and Senecio heaths between 2 400 and 3 650 m. The present material

Biophysical approaches for studying viral entry
FEBS Letters, EarlyView.Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

How many species in the Southern Ocean? Towards a dynamic inventory of the Antarctic marine species
, 2011 The IPY sister-projects CAML and SCAR-MarBIN provided a timely opportunity, a strong collaborative framework and an appropriate momentum to attempt assessing the "Known, Unknown and Unknowable" of Antarctic marine biodiversity.
