Aircraft engines release CO2 into the atmosphere, but particles produced from aircraft emissions can also affect climate through aerosol production that leads to cloud formation. Moore et al. examined how incorporating plant-based biofuels (Camelina oil) affected the production of aerosols. They found…

Cell walls are complex mixtures of cellulose microfibrils, proteins and other materials. Their mechanical properties can be measured and modeled, but it is not always simple to translate these measurements to changes at the molecular level. Zhang et al. used atomic force microscopy to provide an unprecedented…

A pair of Breakthrough Technology papers in Plant Physiology discusses new tools to identify hydroxyproline-rich glycoproteins and insights into their evolution. Hydroxyproline-rich glycoproteins (HRGPs) are repeat-rich cell wall proteins that have been described as falling into three large families:…

Rubisco, the fundamental enzyme required for photosynthetic carbon fixation, is susceptible to inactivation by the inhibitory binding of various metabolites. Rubisco activases (Rca’s) are enzymes that remodel Rubisco and facilitate the elimination of the inhibitor. All photosynthetic organisms have…

When the uptake of CO2 (A) is plotted against absorbed irradiance (I), at low I there is a noticeable bend that occurs around the light compensation point (I where CO2 release due to mitochondrial respiration is balanced by CO2 uptake by photosynthesis). When the slopes of both parts of the curve are…

Jatropha curcas is a perennial woody plant with high seed oil content that has potential to be used in biofuel production.  However, there is limited knowledge about the biology of seed oil production in Jatropha spp.  Sun. et al., used a genetic approach to identify a J. curcas QTL that controls seed…

Eucalypts are fast-growing trees increasingly exploited for pulp, paper, bioenergy and other wood-based products. Using genetics tools and a network-based data integration (NBDI) approach, Mizrachi et al. explore a segregating Eucalyptus hybrid population for genes and pathways underlying biomass / bioenergy…

Our way of life depends on the chemical manufacture of thousands of products. Some of these can be produced through biomanufacturing, which may involve starting with a biological starting material, or using an enzyme or organism as catalyst. Advances in synthetic biology, metabolic engineering and genomics…
