MYC2 Differentially Modulates Diverse Jasmonate-Dependent Functions in Arabidopsis[W]
TLDR
It is found that MYC2 negatively regulates Trp and Trp-derived secondary metabolism such as indole glucosinolate biosynthesis during JA signaling and positively regulates JA-mediated resistance to insect pests, and tolerance to oxidative stress, possibly via enhanced ascorbate redox cycling and flavonoid biosynthesis.
Biofumigation and Enhanced Biodegradation: Opportunity and Challenge in Soilborne Pest and Disease Management
TLDR
Despite this success, biofumigation is not seen as being sufficiently powerful or practical in implementation to be an alternative to methyl bromide on a broad scale and misdirection in that regard could be counterproductive to more appropriately targeted further development.
Traits and selection strategies to improve root systems and water uptake in water-limited wheat crops.
TLDR
It is proposed that wheat varieties with a deeper root system, a redistribution of branch root density from the surface to depth, and with greater radial hydraulic conductivity at depth would have higher yields in rainfed systems where crops rely on deep water for grain fill.
Impact of subsoil water use on wheat yield
TLDR
It is demonstrated that relatively small amounts of subsoil water can be highly valuable to grain yield and 3 times that typically expected for total seasonal water use, and twice that previously estimated for total post-anthesis water use in a similar environment.
Break crops and rotations for wheat
TLDR
This review quantifies the yield increase, based on >900 comparisons of wheat growing after a break crop with wheat after wheat, to provide a basis for the decision to grow continuous cereal crops, strategic rotations or tactically selected break crops.
Beyond conservation agriculture
TLDR
A rigorous, context-sensitive approach based on Systems Agronomy is proposed to analyze and explore sustainable intensification options, including the potential of Conservation Agriculture, and suggest pragmatic adoption on larger mechanized farms, and limited uptake by smallholder farmers in developing countries.
Biofumigation potential of brassicas
TLDR
Investigation of in vitro toxicity of six ITCs to the mycelial growth of five cereal root pathogens suggests there is significant scope to enhance the biofumigation potential of brassicas by selecting those which produce large quantities of GSL precursors to the most toxic I TCs for the target organism.
