New database catalogues plants that soak up contamination

Hyperaccumulators are unusual plants that can absorb much larger amounts of metal compounds in their leaves and stems than normal plants, and they are very useful for cleaning up contaminated land.

Genome of wheat ancestor sequenced 

In the study, published Nov. 15 in the journal Nature, researchers applied a combination of advanced technologies to generate a reference-quality genome sequence for Ae. tauschii, which is highly adaptable and tolerant of diseases. It is also the primary source of genes for the bread-making properties of wheat flour.

Light green plants save nitrogen without sacrificing photosynthetic efficiency

Scientists designed plants with light green leaves with hopes of allowing more light to penetrate the crop canopy and increase overall light use efficiency and yield. This strategy was tested in a recent modeling study that found leaves with reduced chlorophyll content do not actually improve canopy-level photosynthesis, but instead, conserve a significant amount of nitrogen that the plant might be able to reinvest to improve light use efficiency and increase yield.

The secret lives of ancient land plants

Researchers have unraveled the genome of the common liverwort -- Marchantia polymorpha -- gaining new insight into how the modest land plants evolved.

Transcription: Shedding light on alternative promoter selection

In Arabidopsis thaliana, in response to light, phytochromes induce the selection of alternative promoters, which can modulate the localization of encoded proteins.

Uncovering essential enzymes for plant growth during nitrogen starvation 

Researchers in Japan have now found that two enzymes involved in lipid biosynthesis called PAH1 and PAH2 are essential for plant growth during nitrogen starvation.

Water world 

Researchers at Washington University in St. Louis have traced the paths of three water channels in an ancient photosynthetic organism to provide the first comprehensive, experimental study of how that organism uses and regulates water to create energy.

Regulation of ethylene-responsive SlWRKYs involved in color change during tomato fruit ripening

Study provides comprehensive molecular evidence that WRKY TFs function in fruit ripening, particularly in color change, and are linked to the intricate regulatory network of other ripening regulators.

Drought-resistant plant genes could accelerate evolution of water-use efficient crops

Scientists at the Department of Energy's Oak Ridge National Laboratory have identified a common set of genes that enable different drought-resistant plants to survive in semi-arid conditions, which could play a significant role in bioengineering and creating energy crops that are tolerant to water deficits.
