Photosynthetic manipulation provides new opportunities for enhancing crop yield. However, understanding and quantifying the importance of individual multiple manipulations on seasonal biomass growth yield performance target crops across variable production environments is limited. Using a state-of-the-art cross-scale model in APSIM platform we predicted impact altering photosynthesis enzyme-limited (Ac ) electron transport-limited (Aj rates, dynamics canopy photosynthesis, growth, formation...
The symbiosome membrane (SM) is a physical barrier between the host plant and nitrogen-fixing bacteria in legume:rhizobia symbiosis, represents regulated interface for movement of solutes symbionts that under control. primary nutrient exchange across SM transport carbon energy source from to bacteroid fixed nitrogen. At biochemical level two channels have been implicated nitrogen uniporter transports monovalent dicarboxylate ions has characterized would carbon. aquaporin NOD26 may provide...
Legumes form a symbiosis with rhizobia in which the plant provides an energy source to bacteria that it uses fix atmospheric nitrogen. This nitrogen is provided legume plant, allowing grow without addition of fertilizer. As part symbiosis, infected cells new root organ, nodule, are surrounded by plant-derived membrane, symbiosome becomes interface between symbionts. Fractions containing membrane (SM) and material from lumen (peribacteroid space or PBS) were isolated soybean nodules analyzed...
The partial pressure of CO 2 at the sites carboxylation within chloroplasts depends on conductance to diffusion from intercellular airspace carboxylation, termed mesophyll ( g m ). We investigated how varies with leaf age and through a tobacco Nicotiana tabacum ) canopy by combining gas exchange carbon isotope measurements using tunable diode laser spectroscopy. combined these anatomical characterization leaves. assimilation rate, A , decreased as leaves aged moved lower in were linearly...
In plants with C3 photosynthesis, increasing the diffusion conductance for CO2 from substomatal cavity to chloroplast stroma (mesophyll conductance) can improve efficiencies of both assimilation and photosynthetic water use. pathway stroma, plasmalemma envelope membranes impose a considerable barrier diffusion, limiting efficiency. an attempt membrane permeability CO2, increase photosynthesis in tobacco, we generated transgenic lines Nicotiana tabacum L. cv Petite Havana carrying either...
Legumes are generally considered to be more responsive elevated CO
The Colorado potato beetle (CPB) is one of the most adaptable insect pests to both plant toxins and synthetic insecticides. Resistance in CPB reported for over 50 classes insecticides, mechanisms insecticide-resistance include enhanced detoxification enzymes, ABC transporters target site mutations. Adaptation insecticides also associated with changes behaviour, energy metabolism other physiological processes seemingly unrelated resistance but partially explained through genomic analyses. In...
Abstract Photosynthetic manipulation provides new opportunities for enhancing crop yield. However, understanding and quantifying effectively how the seasonal growth yield dynamics of target crops might be affected over a wide range environments is limited. Using state-of-the-art cross-scale model we predicted crop-level impacts broad list promising photosynthesis strategies C 3 wheat 4 sorghum. The targets have varying effects on enzyme-limited ( A c ) electron transport-limited j rates...
