Understanding plant resilience by putting photosynthesis and photorespiration in the metabolic context. [PDF]

Planta
MAIN CONCLUSION: Photorespiration is a dynamic metabolic process that contributes to energy balance, stress resilience, and nutrient flux, warranting its integration into genome-scale models to enhance plant productivity and climate adaptation. ABSTRACT:

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Physiological Roles of Flavodiiron Proteins and Photorespiration in the Liverwort Marchantia polymorpha

Frontiers in Plant Science, 2021
Against the potential risk in oxygenic photosynthesis, that is, the generation of reactive oxygen species, photosynthetic electron transport needs to be regulated in response to environmental fluctuations. One of the most important regulations is keeping

Improved primary production and gross respiration measurements using the H218O technique with membrane inlet mass spectrometry and introduction of a small volume–uniform irradiance incubation chamber

Journal of Phycology, EarlyView.
Abstract An improvement in the H218O technique for phytoplankton gross primary productivity (GPP), net primary productivity (NPP), and gross respiration (GR) is described that reduces cost, labor, and time over the traditional isotope ratio mass spectrometer (IRMS) method.

Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

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 ...

Drought and oxidative load in the leaves of C3 plants: a predominant role for photorespiration?

, 2002
Although active oxygen species are produced at high rates in both the chloroplasts and peroxisomes of the leaves Of C-3 plants, most attention has focused on the potentially damaging consequences of enhanced chloroplastic production in stress conditions ...

Growth Temperature Alters the Thermal Sensitivity of Mesophyll Conductance in Wild and Cultivated Tomato

Plant, Cell &Environment, EarlyView.
ABSTRACT Mesophyll conductance (gm) is a key component of internal CO2 diffusion and can limit photosynthesis in C3 leaves. Temperature responses of gm are commonly treated as intrinsic properties of the leaf, yet it remains unclear whether they acclimate to growth conditions. Here, we tested whether growth temperature alters the thermal sensitivity of
