Systematics of the southern African genus Ixia (Iridaceae). 1. The I. rapunculoides complex

open access: yesBothalia: African Biodiversity & Conservation, 2008
Field and laboratory investigation of the six varieties of Ixia rapunculoides Delile (recognized in the current revisions and flora accounts of this southern African genus of some 65 species) show that a revised taxonomy better reflects the biology of ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Pepila Weise: Taxonomic identity of the genus and revision of the megalopoides species-group, and description of two new species from Australia (Coleoptera: Chrysomelidae: Alticinae)

open access: yesEuropean Journal of Entomology, 2003
In this paper some taxonomic observations on the Australian flea beetle genus Pepila Weise, 1923 are reported. The following species are transferred to the genus Pepila and lectotypes for them designated: Chaetocnema carinata Baly, 1877; Plectroscelis ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Pleopeltis (Polypodiaceae), a redefinition of the genus and nomenclatural novelties

open access: yesBotan‪ical Sciences, 2014
Recent evidence from morphological, cytological, and gene sequencing studies has provided much additional evidence that the genus Pleopeltis (Polypodiaceae) requires redefinition to include other polypod genera and species with peltate scales on the ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
