Plant-associated microbiome plays important role in maintaining overall health of the host plant. Xanthium strumarium displaying resilience to various environmental fluctuations may harbor some bacterial isolates which can help this plant to grow worldwide. The present study aims to isolate endophytic and rhizospheric bacteria from X.

Biomolecular condensation has emerged as an important mechanism to control various cellular processes through the formation of membraneless organelles. Fluorescent protein tags have been extensively used to study the formation and the properties of condensates and , but there is evidence that tags may perturb the condensation properties of proteins. In this study, we carefully assess the effects of protein tags on the yeast DEAD-box ATPase Dhh1, a central regulator of processing bodies (P-bodies), which are biomolecular condensates involved in mRNA metabolism.

An unusual clathrate-type meroterpenoid isoatlantinone A (1), two new steroids acrocalysterols E (2) and F (3), together with fifteen known compounds (4-18) were separated from a plant-associated fungus Penicillium fellutanum. Their structures and absolute configurations were established based on spectroscopic data (NMR and HRESIMS), electronic circular dichroism (ECD) and modified Mosher's method. Notably, compound 1 represents an unusual highly oxygenated meroterpenoid derivative with a unique caged bioxatetracyclo-[6.

Quorum sensing controls numerous processes ranging from the production of virulence factors to biofilm formation. Biofilms, communities of bacteria that are attached to one another and/or a surface, are common in nature, and when they form, they can produce a quorum of bacteria. One model system to study biofilms is the bacterium , which forms a biofilm that promotes the colonization of its symbiotic host.

Paediatric relapse/refractory T-cell acute lymphoblastic leukaemia (T-ALL) is notoriously difficult to treat. This group of heavily pre-treated patients needs effective agents that can rapidly control the disease while not having significant toxicity. Homoharringtonine (HHT) has been widely used in children with acute myeloid leukaemia, but there is little information on T-ALL.
