Brazilian Archives of Biology and Technology, 2006 This work studied the morphology and post-seminal development of seeds of Tillandsia gardneri Lindl., T. streptocarpa Baker, and T. stricta Sol. ex Sims (Bromeliaceae) from the "Campos Gerais", State of Paraná, Southern Brazil. The seeds (ca. 2.0 mm long)

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Seed morphology and germination of Ensete ventricosum (Musaceae)
, 2013 Ensete ventricosuni is a drought-tolerant, multipurpose crop that has been cultivated in Ethiopia since ancient times. Traditional propagation is vegetative: each of hundreds of existing landraces is a clone.

Seed certification and maize, rice, and cowpea productivity in Nigeria
, 2023 Despite the potential importance of seed quality to agricultural productivity growth, many governments in sub-Saharan Africa lack the capacity to expand quality assurance systems even where there is expressed interest.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Modelling stem cell differentiation related processes—A practical overview for biologists
FEBS Letters, EarlyView.Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Securing access to seed: social relations and sorghum seed exchange in eastern Ethiopia [PDF]
, 2008 Access to seed is crucial for farming, though few studies investigate household-level access in the informal ‘farmer seed systems’ which still supply most seed in poor countries.
