Scientists on Twitter: Preaching to the choir or singing from the rooftops?

Science communication is as old as science itself, reaching even best-selling levels with some extraordinary examples such as “On the Origin of Species” by Charles Darwin or “A Brief History of Time: From the Big Bang to Black Holes” by Stephen Hawking. Currently, and thanks to social media, communication including science communication is incredibly accelerated. […]

Opinion: Non-mycorrhizal Plants: The exceptions that prove the rule (TIPS)

Most vascular plants establish in their roots a multifunctional symbiosis with arbuscular mycorrhizal (AM) fungi.  Among the 29% that do not host AM fungi are 66-92%  of the members of the Brassicaceae family, including some major crops (broccoli, oilseed rape) as well as the model plant Arabidopsis thaliana.  Although Arabidopsis is considered a non-host, conditional […]

Insight: The impact of domestication and crop improvement on arbuscular mycorrhizal symbiosis in cereals (New Phytol)

Cereals, such as rice, maize, wheat and sorghum are the nutritional base for many human societies, accounting for over 50% of the global caloric intake. Therefore, sustainability of (cereal) agriculture and quality of the cereals consumed is a great concern. This has led to an increasing interest into the potential benefit of arbuscular mycorrhizal (AM) […]

Impact of genetically engineered maize on agronomic, environmental and toxicological traits (Sci. Rep.)

The question of the relative risks and benefits of genetically engineered (GE) maize is still in the middle of a heated debate, despite the widespread cultivation of GE crops (12% of the global crop-land) and long standing commercialization (since 1996).  Pellegrino et al. report a meta-analysis of the existing data on the GE maize related […]

Review: The pivotal role of ethylene in plant growth (Trends Plant Sci)

Phytohormones, their ratios and gradients, regulate plant development to allow them to adapt to environment changes.  Ethylene, one such hormone, is produced in response to a multitude of stresses: biotic, osmotic, flooding, drought or even shading by neighbors. Dubois et al. report in this review how ethylene specifically regulates plant growth, mainly focussing in leaves. […]

REVIEW Cryobiotechnology of apple (Malus spp.) (Plant Cell Rep.) ($)

Apple  (Malus spp.) is an economically important tree that faces, like other crops cultured in temperate regions, remarkable challenges due to climate change such as abiotic (drought and salinity) and biotic (fungi, bacteria and aphids) stresses. For that, there is increasing need to preserve Malus genetic resources (wild and commercial varieties) with potentially valuable genes […]

Transcriptome mapping of tomato fruit development and ripening (Nature Comms)

Tomato (Solanum lycopersicum) is today the main model to study fleshy fruit development. Until now, most tomato growth and ripening studies are focused on a single tissue, the pericarp, and do not take into consideration the development of internal tissues. Shinozaki et al. provide an extensive spatiotemporal transcriptome analysis, with 24,660 unique genes detected, of […]

NEWS Germany vs Elsevier: universities win temporary journal access after refusing to pay fees (Nature)

During 2017, a consortium of 200 German research institutions was in conversations with the publishing group Elsevier to achieve a collective deal for full online access to Elsevier journals. This deal would have granted them access to about 2.500 journals for half the market price.  After they could not reach an agreement by December 2017, […]
