Antiviral mechanism in plant stem cells discovered [Full subscriber]

Plant stem cells and their newly differentiated daughter cells in the shoot apical meristem (SAM) provide cells for all aboveground organs during postembryonic development. This tissue is free from viral invasion. Researchers at the University of Science and Technology of China (USTC) have offered new insights into this incredible ability.

Bioengineering plants to turn them into biofactories for new molecules [Full subscriber]

Plants can produce a wide range of molecules, many of which help them fight off harmful pests and pathogens. Biologists have harnessed this ability to produce many molecules important for human health — aspirin and the antimalarial drug artemisinin, for example, are derived from plants. Now, researchers at the Joint BioEnergy Institute (JBEI) and Stanford University have designed and engineered new synthetic metabolic pathways to create new-to-nature biopesticides with novel anti-fungal activity.

Genes from baker’s yeast help plants tolerate contaminated soils [Registered]

Most plant species, including crops, cannot tolerate the toxic effects of soil pollutants, which dramatically impair their growth and development. Researchers at the Instituto Gulbenkian de Ciencia (IGC; Portugal) have discovered two genes in baker’s yeast that are capable of increasing plant resistance to a broad range of contaminants. This could allow plants and crops to thrive despite soil pollution.

Breakthrough in understanding aging in plants [Registered]

Researchers at Tohoku University have identified a previously uncharacterized type of autophagy, during which an autophagic process termed chlorophagy removes collapsed chloroplasts in plant leaves. The findings could lead to new methods for controlling the aging of plants.

Study finds carbon-hungry plants impede growth rate of atmospheric CO2 [Registered]

New findings suggest the rate at which CO2 is accumulating in the atmosphere has plateaued in recent years because Earth’s vegetation is grabbing more carbon from the air than in […]

Mechanism behind plants capitulating to environmental stress identified [Registered]

Researchers at the Kobe University Graduate School of Agricultural Science have identified the reaction in which harmful reactive oxygen species are created during photosynthesis, and along with it the mechanism behind plant withering. This discovery could help to ensure stable food supplies by cultivating plants that can are able to withstand environmental stresses.
