Plant roots sense soil compaction through restricted ethylene diffusion

Science, 2021
Ethylene aplenty signals soil compaction It's tough to drive a spade through compacted soil, and plant roots seem to have the same problem when growing in compacted ground. Pandey et al.

Cadmium-induced ethylene production and responses in Arabidopsis thaliana rely on ACS2 and ACS6 gene expression [PDF]

, 2014
Background: Anthropogenic activities cause metal pollution worldwide. Plants can absorb and accumulate these metals through their root system, inducing stress as a result of excess metal concentrations inside the plant.

Synthesis of difluoromethylated allenes through trifunctionalization of 1,3-enynes

Nature Communications, 2020
Fluorinated or fluoroalkylated allenes are versatile building blocks for medicinal and material chemistry. Here, the authors show a regioselective trifunctionalization of 1,3-enynes proceeding through double C-F bond formation and concomitant ...

Asymmetric radical carboesterification of dienes

Nature Communications, 2021
Stereocontrol of C–O bond formation from a carbon-based radical is very difficult due to the rapid inversion of the carbon radical. Here the authors present a method to form chiral esters from conjugated dienes with copper and chiral PyBox ligands ...

Role of ethylene on various ripening pathways and on the development of sensory quality of Charentais cantaloupe melons [PDF]

, 2002
Charentais melons (Cucumis melo L., var cantalupensis Naud.) in which ethylene biosynthesis has been suppressed by an antisense ACC oxidase gene have been used to better understand the role of ethylene in the regulation of the ripening process of ...

Easy access to medium-sized lactones through metal carbene migratory insertion enabled 1,4-palladium shift

Nature Communications, 2020
Transannular construction of medium-sized lactones is entropically unfavoured. Herein, the authors describe a strategy for valuable medium-sized lactone synthesis from available benzaldehydes by selective C-H bond functionalization via palladium carbene ...
