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, […]

REVIEW In vitro propagation of bamboo species (Plant Cell Tissu Organ Cult) ($)

Bamboos are economically important plants, with versatile applications including use in construction, paper, textiles and food production and bioenergy uses among others. Traditional methods of plant propagation are revealed to be challenging in this plant. First, bamboo propagation through seeds could be problematic, due to short seed viability, massive consumption by small animals and genetic […]

Transcriptomic analysis of wound xylem formation in Pinus canariensis (BMC Plant Biol.)

Woody plants, given their usually long life span, typically must face during their life several injuries that could take as long as several years to heal.  In their work, Chano et al. use microarray analysis and RT-PCR to analyze the transcriptome changes that occurs during wood formation after a trauma in the conifer Pinus canariensis. Their results […]
