Scientific Reports, 2017 Annual gross primary productivity (GPP) varies considerably due to climate-induced changes in plant phenology and physiology. However, the relative importance of plant phenology and physiology on annual GPP variation is not clear.

Frontiers in Plant Science, 2014 Calcium (Ca2+) is a second messenger involved in many plant signalling processes. Biotic and abiotic stimuli induce Ca2+ signals within plant cells, which, when decoded, enable these cells to adapt in response to environmental stresses. Multiple examples

Two dominant boreal conifers use contrasting mechanisms to reactivate photosynthesis in the spring
Nature Communications, 2020 Boreal conifers regulate photosynthesis to maximize seasonal growth while limiting damage due to light and cold stress. Here Yang et al. show that two major conifer species achieve this via different means as Scots pine, but not Norway spruce, activates ...

Sphagnum physiology in the context of changing climate: emergent influences of genomics, modelling and host-microbiome interactions on understanding ecosystem function. [PDF]
, 2014 Peatlands harbour more than one-third of terrestrial carbon leading to the argument that the bryophytes, as major components of peatland ecosystems, store more organic carbon in soils than any other collective plant taxa. Plants of the genus Sphagnum are

Pediatric Blood &Cancer, EarlyView.ABSTRACT Bone tumours present significant challenges for affected patients, as multimodal therapy often leads to prolonged physical limitations. This is particularly critical during childhood and adolescence, as it can negatively impact physiological development and psychosocial resilience.

Combined genetic, genomic and physiological approaches to characterize flowering in Fragaria [W324] [PDF]
, 2015 Flowering is a key event for production of seeds or fruits. To date, studies of this process were mainly focused on the molecular mechanisms involved in the control of flowering until now.

Redox regulation of PEP activity during seedling establishment in Arabidopsis thaliana
Nature Communications, 2018 The plastid-encoded RNA polymerase PEP is regulated according to plastid redox state. Here, the authors show that the redox-regulated PRIN2 protein is reduced to monomeric form in a thiol-dependent manner in response to light and that PRIN2 monomers are ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Solving the woolly mammoth conundrum: amino acid 15N-enrichment suggests a distinct forage or habitat [PDF]
, 2015 Understanding woolly mammoth ecology is key to understanding Pleistocene community dynamics and evaluating the roles of human hunting and climate change in late Quaternary megafaunal extinctions. Previous isotopic studies of mammoths’ diet and physiology

Strigolactones initiate the formation of haustorium-like structures in Castilleja
iScienceSummary: Strigolactones serve as germination signals for several root-parasitic plant species within the Orobanchaceae family. Yet, their role in the life cycle of the facultatively parasitic genus Castilleja has remained elusive.
