Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?
Plant, Cell &Environment, EarlyView.ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Future climate CO2 levels mitigate stress in plants: increased defense or decreased challenge?
Frontiers in Plant Science, 2016 Elevated atmospheric CO2 can stimulate plant growth by providing additional C (fertilization effect), and is observed to mitigate abiotic stress impact.

Plant, Cell &Environment, EarlyView.ABSTRACT Glutathione, including reduced glutathione (GSH) and oxidized glutathione (GSSG), is the major non‐protein thiol‐based redox buffer. There are diurnal rhythms in total glutathione level and in this work, we investigate whether these oscillations might be indicative of circadian regulation of total glutathione homeostasis.

The Intracellular Distribution of Folate Derivatives in Pea Leaves
Pteridines, 2003 After hydrolysis of polyglutamate derivatives, leaf extracts of pea (Pisum sativum L.) seedlings were examined for individual folates using high Performance liquid chromatography and microbiological assays employing Lactobacillus rhamnosus and ...

Plant, Cell &Environment, EarlyView.ABSTRACT We studied near‐instantaneous temperature responses of light‐saturated photosynthesis (Asat) and the operating efficiency of photosystem II (ΦPSII) in relation to acclimation of photosynthetic biochemistry to temperature at the timescale of 1–8 days. We grew two closely related Brassica oleracea L.

Plasticity in metabolism underpins local responses to nitrogen in Arabidopsis thaliana populations
Plant Direct, 2019 Nitrogen (N) is central for plant growth, and metabolic plasticity can provide a strategy to respond to changing N availability. We showed that two local A.

Plant, Cell &Environment, EarlyView.ABSTRACT Improving photosynthesis is proposed as a means of enhancing crop productivity. To assess whether simultaneous increases in light use‐efficiency and carbon assimilation are additive, we investigated the impact of elevated CO2 on the performance of a transgenic soybean line engineered for faster relaxation of photoprotection by overexpression ...

Plant, Cell &Environment, EarlyView.ABSTRACT Global warming and increasing water scarcity pose major challenges to agriculture, emphasising the need to translate stress‐biology insights into the development of drought‐resilient cultivars. In this study, we evaluated a panel of six diverse sorghum (Sorghum bicolour) accessions grown under field‐imposed drought conditions in central ...

A cytosolic glyoxylate shunt complements the canonical photorespiratory pathway in Arabidopsis
Nature CommunicationsPhotorespiration functions in part to support photosynthetic performance, especially under stress such as high light, yet the underlying mechanisms are poorly understood.
