Guard cell photorespiration controls stomata behavior and development

New Phytologist, EarlyView.
Summary Photorespiration is traditionally viewed as a limitation to photosynthetic efficiency. However, it is mandatory for safeguarding the Calvin–Benson–Bassham cycle from inhibitory byproducts through Rubisco‐mediated oxidative misfire and is tightly integrated with primary metabolism.

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 ...

OsMT2b Regulates Pollen Development and ROS Homeostasis in a Photoperiod‐Dependent Manner

Plant Biotechnology Journal, EarlyView.
ABSTRACT Reactive oxygen species (ROS) are signalling molecules that promote programmed cell death in animal and plant systems. However, their role in rice (Oryza sativa L.) anther development is unclear. In this study, we show that lower transcript levels of the metallothionein gene OsMT2b in japonica rice plants obtained by RNA interference (RNAi ...

Ecophysiological traits of grasses: resolving the effects of photosynthetic pathway and phylogeny [PDF]

, 2009
C4 photosynthesis is an important example of convergent evolution in plants, having arisen in eudicots, monocots and diatoms. Comparisons between such diverse groups are confounded by phylogenetic and ecological differences, so that only broad ...

The C2H2‐GGAT Regulatory Module Fine‐Tunes Glutamate Homeostasis to Improve Fruit Flavour and Enhance Disease Resistance in Peach

Plant Biotechnology Journal, EarlyView.
ABSTRACT Free amino acids (FAAs) play a fundamental role in determining fruit quality and stress adaptation, yet their genetic regulation remains poorly understood. Through an integrated approach combining metabolomic and sensory analyses of 120 peach (Prunus persica) hybrids, we identified glutamate as a key metabolite linking FAA content to umami ...

Evolution of Photorespiratory Glycolate Oxidase among Archaeplastida

Plants, 2020
Photorespiration has been shown to be essential for all oxygenic phototrophs in the present-day oxygen-containing atmosphere. The strong similarity of the photorespiratory cycle in cyanobacteria and plants led to the hypothesis that oxygenic ...

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.

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 ...

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 (

Oxygen Requirement and Inhibition of C4 Photosynthesis . An Analysis of C4 Plants Deficient in the C3 and C4 Cycles [PDF]

, 1998
The basis for O2 sensitivity of C4 photosynthesis was evaluated using a C4-cycle-limited mutant of Amaranthus edulis (a phosphoenolpyruvate carboxylase-deficient mutant), and a C3-cycle-limited transformant of Flaveria bidentis (an antisense ribulose-1,5-
