A new asymmetric photocyclization-reduction cascade employing readily available aminochalcones has been developed. The reaction sequence has been achieved by unifying photochemistry and asymmetric Brønsted acid catalysis and involves photocyclization followed by Brønsted acid catalyzed enantioselective hydrogenation in batch and flow.

Introduction: Surgical gastric fundoplication is an effective treatment option for gastroesophageal reflux disease. In contrast to acid suppression, fundoplication nearly abolishes all types of reflux, acid and nonacid. However, in some cases lasting side effects of the procedure may overshadow its positive effects.

The mini-cutting physiological condition is vital for the rooting process. For accurate interpretation, considering all mini-cutting responses in an experiment is necessary to identify significant rooting-biomarkers. The study investigates rooting-biomarkers during vegetative propagation, focusing on Ilex paraguariensis (yerba mate) clones of contrasting mini-cutting rooting performance as a case study (i.

Translation initiation, which involves numerous protein factors and coordinated control steps, represents the most complicated process during eukaryotic translation. However, the roles of eukaryotic translation initiation factor (eIF) in filamentous fungi are not well clarified. In this study, we investigated the function of eIF2Bα in Aspergillus oryzae, an industrially important filamentous fungus.

AtbZIP69 overexpression in wheat significantly enhanced drought and low nitrogen tolerance by modulating ABA synthesis, antioxidant activity, nitrogen allocation, and transporter gene expression, boosting yield. In this study, we generated wheat plants with improved low nitrogen (LN) and drought tolerance by introducing AtbZIP69, a gene encoding a basic leucine zipper domain transcription factor, into the wheat cultivar Shi 4056. AtbZIP69 localized to the nucleus and activated transcription.
