Ecological Entomology, EarlyView.Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

, 2006 Regulatory transcription factors (rTFs), which bind specific DNA sequences in the regulatory regions of genes and subsequently activate or repress transcription, play a central role in programming genomic expression. The number of rTFs in a species might

Septin-dependent compartmentalization of the endoplasmic reticulum during yeast polarized growth [PDF]
, 2005 Polarized cells frequently use diffusion barriers to separate plasma membrane domains. It is unknown whether diffusion barriers also compartmentalize intracellular organelles.

The sorting nexin Snx21 promotes flotillin‐mediated endocytosis
The FEBS Journal, EarlyView.In this study, we describe a novel function of the previously uncharacterized Snx21 protein as a specific positive regulator of flotillin‐mediated endocytic trafficking. Snx21 is recruited to endosomal membranes via binding to PI(3)P, and it colocalizes with flotillins on the surface of late endosomes.

A Plant-Derived Antifungal Agent, Poacic Acid, Inhibits Germination and Tube Growth of Lily Pollen
PlantsPoacic acid is a novel natural antifungal agent. It inhibits the growth of fungal cells, including budding yeast Saccharomyces cerevisiae, by inhibiting the synthesis of β-1,3-glucan, which is a major component of the fungal cell wall.

Single Cell Isolation Using Optical Tweezers
Micromachines, 2018 Optical tweezers offer a non-contact method for selecting single cells and translocating them from one microenvironment to another. We have characterized the optical tweezing of yeast S. cerevisiae and can manipulate single cells at 0.41 ± 0.06 mm/

The FEBS Journal, EarlyView.Chromosomal DNA double‐strand breaks (DSBs) are repaired by homologous recombination and nonhomologous end joining (NHEJ). Recent work has additionally established theta‐mediated end‐joining (TMEJ) as a mechanism for DSB joining. Cells lacking NHEJ and TMEJ can repair DSBs in a homology‐dependent manner.

The role of AgRax1p, AgRax2p, AgBud7p and AgBud10p in mycelial development of the filamentous fungus "Ashbya gossypii" [PDF]
, 2005 Polarized growth is essential for hyphal and mycelial morphogenesis. The diversity of fungal morphology and development raises many questions considering the mechanism involved in selection of new polar growth sites. Landmark events of fungal growth

The FEBS Journal, EarlyView.This review summarizes recent structures of the UBR4 complex, a giant E4 ubiquitin ligase which recognizes proteins with pre‐existing ubiquitin modifications and marks them for degradation. The UBR4 complex uses a large arena lined with substrate interaction modules to select features on ubiquitinated substrates, such as the presence of N‐degrons or ...

Ploidy‐dependent modulation of DNA replication kinetics in Xenopus
The FEBS Journal, EarlyView.Using an interspecies replication system with Xenopus frog species of different ploidy levels, we investigated how DNA replication adapts to polyploidization. While replication was slower in tetraploid than in diploid nuclei, dodecaploid nuclei unexpectedly replicated faster than tetraploid nuclei. Our findings show that increasing genome size does not
