Climate change and crop resilience: harnessing metabolomics for predicting stress tolerance

New Phytologist, EarlyView.
Summarised methodology for metabolite biomarker discovery and genomic targets selection for those metabolites to predict high‐throughput phenotypic and agronomic traits of interest for direct uptake in breeding programmes. Summary Global warming is driving climate change to levels not experienced since the advent of agriculture, primarily due to ...

The Coevolution of RuBisCO, Photorespiration, and Carbon Concentrating Mechanisms in Higher Plants

Frontiers in Plant Science, 2021
Ribulose-1,5-bisphosphate (RuBP) carboxylase/oxygenase (RuBisCO) is the carbon-fixing enzyme present in most photosynthetic organisms, converting CO2 into organic matter.

C4 photosynthetic anatomy is associated with higher leaf hydraulic conductance and capacitance in Alloteropsis semialata

New Phytologist, EarlyView.
Bulk leaf capacitance (Cbulk) in relation to bundle sheath area (BSA) and leaf dimensions in Alloteropsis semialata plants differing in photosynthetic type (C3, C3–C4 or C4) and ploidy level (2x, 6x or 12x). Summary The evolution of C4 photosynthesis requires biochemical innovations to be coordinated with anatomical modifications.

Toward eradication of B-vitamin deficiencies : considerations for crop biofortification [PDF]

, 2018
'Hidden hunger' involves insufficient intake of micronutrients and is estimated to affect over two billion people on a global scale. Malnutrition of vitamins and minerals is known to cause an alarming number of casualties, even in the developed world ...

Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

Plant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

A synthetic glycolate metabolism bypass in rice chloroplasts increases photosynthesis and yield

Crop Journal
Photorespiration consumes photosynthetically fixed carbon and reduces yields by 20%–50% in C3 crops. In an attempt to increase photosynthetic efficiency in rice by bypassing the carbon-consuming process of photorespiration, a photorespiratory bypass ...

Photosynthesis and Photorespiration in Algae [PDF]

Plant Physiology, 1977
The CO(2) exchange of several species of fresh water and marine algae was measured in the laboratory to determine whether photorespiration occurs in these organisms. The algae were positioned as thin layers on filter paper and the CO(2) exchange determined in an open gas exchange system.

Rubisco evolution in C4 eudicots: an analysis of Amaranthaceae sensu lato [PDF]

, 2015
BACKGROUND Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) catalyses the key reaction in the photosynthetic assimilation of CO₂. In C₄ plants CO₂ is supplied to Rubisco by an auxiliary CO₂-concentrating pathway that helps to maximize the ...

Contextualized Metabolic Modelling Revealed Factors Affecting Isoflavone Accumulation in Soybean Seeds

Plant, Cell &Environment, EarlyView.
ABSTRACT Isoflavones, secondary metabolites with numerous health benefits, are predominantly found in legume seeds, especially soybean; however, their contents in domesticated soybean seeds are highly variable. Wild soybeans are known for higher seed isoflavone contents than cultivars. Here we used experimental and modelling approaches on wild soybean (

Intracellular position of mitochondria and chloroplasts in bundle sheath and mesophyll cells of C3 grasses in relation to photorespiratory CO2 loss

Plant Production Science, 2016
In C3 plants, photosynthetic efficiency is reduced by photorespiration. A part of CO2 fixed during photosynthesis in chloroplasts is lost from mitochondria during photorespiration by decarboxylation of glycine by glycine decarboxylase (GDC).
