Subgenome Dominance in Allotetraploid Actinidia valvata Regulates RNA m6A Modification for Waterlogging Tolerance

open access: yesAdvanced Science, EarlyView.
The waterlogging tolerance of allotetraploid Actinidia valvata is inherited from one of its diploid progenitors, which leads to subgenome expression dominance, mediated by complex mechanisms including altered chromatin accessibility and DNA methylation.

Overcoming Challenges in Small‐Ring Transfer: Direct Decarboxylative Hydroalkylation of Alkenes via Iron‐Thiol Catalysis

open access: yesAngewandte Chemie, EarlyView.
Herein, we present a catalytic approach for the direct decarboxylation of challenging CF3‐cyclopropyl and cyclobutyl carboxylic acids using cooperative iron‐thiol catalysis. This strategy enables the efficient generation of valuable radicals that can be incorporated into activated and unactivated alkenes, offering access to elusive chemical space ...
