Underground Signals: The Ecological Power of Root Volatiles

Advanced Science, EarlyView.
Root volatiles mediate rhizosphere chemical communication, shaping interactions among plants, microbes, herbivores, and natural enemies. Their production, transport, and perception underpin ecological adaptation, multitrophic interactions, and plant resilience, offering opportunities for sustainable crop protection, resilient agroecosystems, and ...

The Correlation of the Presence and Expression Levels of cry Genes with the Insecticidal Activities against Plutella xylostella for Bacillus thuringiensis Strains

Toxins, 2014
The use of Bacillus thuringiensis (Bt) strains with high insecticidal activity is essential for the preparation of bioinsecticide. In this study, for 60 Bt strains isolated in Taiwan, their genotypes and the correlation of some cry genes as well as the ...

Calcium‐Mechanochemistry Enabled Ketone Synthesis From Organic Iodides and Carboxylic Acids

Advanced Science, EarlyView.
Mechanochemically generated organocalcium species display unusual chemoselectivity toward carboxylates, enabling direct ketone synthesis without overaddition. Ball milling activates commercial calcium metal under ambient, solvent‐minimized conditions, providing a broad substrate scope, high functional‐group tolerance, and a practical one‐step ...

The pyrethrins and related compounds. Part XXXVIII. Optimisation of insecticidal activity in 3-[(alkoxyimino)methyl]-4-fluorobenzyl esters

, 1995
Optimisation of activity in 3-[(alkoxyimino)methylbenzyl] esters has been investigated by introducing an alpha-cyano group and a fluorine atom in position 4 of the benzylic moiety in conjunction with varying the length and nature of the side chain.
