Primary hybrid zone formation in Tephroseris helenitis (Asteraceae), following postglacial range expansion along the central Northern Alps

Distinguishing between secondary versus primary hybrid zone formation remains a challenging task as, for instance, the time window in which these historical (vicariant) versus contemporary (environmental‐selective) processes are distinguishable may

Plant speciation in the Namib Desert: origin of a widespread derivative species from a narrow endemic

Autor: Joseph J. Milton, Matthias Affenzeller, Richard J. Abbott, Hans P. Comes

BackgroundParapatric (or ‘budding’) speciation is increasingly recognized as an important phenomenon in plant evolution but its role in extreme (e.g. desert) environments is poorly documented.AimsTo test this speciation model in a hypothesized si

Publikováno v: Journal of Plant Physiology. 208:115-127

Autophagy is regarded as crucial intracellular process in plant development but also in intracellular stress response. It is known to be controlled by the energy level of the cell and consequently can be triggered by energy deprivation. In this study

Cell death upon H2O2induction in the unicellular green algaMicrasterias

Autor: Matthias Affenzeller, Ursula Lütz-Meindl, Anza Darehshouri

Publikováno v: Plant Biology. 10:732-745

In the present study, we investigated whether the unicellular green alga Micrasterias denticulata is capable of executing programmed cell death (PCD) upon experimental induction, and which morphological, molecular and physiological hallmarks characte

Plant secondary metabolism significantly contributes to defensive measures against adverse abiotic and biotic cues. To investigate stress-induced, transcriptional alterations of underlying effector gene families, which encode enzymes acting consecuti
