CO mesophyll conductance regulated by light: a review.

Light quality and intensity regulate plant mesophyll conductance, which has played an essential role in photosynthesis by controlling leaf structural and biochemical properties. Mesophyll conductance (g), a crucial physiological factor influencing the photosynthetic rate of leaves, is used to describe the resistance of CO from the sub-stomatal cavity into the chloroplast up to the carboxylation site. Leaf structural and biochemical components, as well as external environmental factors such as light, temperature, and water, all impact g.

Palladium-Catalyzed Oxidative Three-Component Coupling of Anthranilamides with Isocyanides and Arylboronic Acids: Access to 2,3-Disubstituted Quinazolinones.

A novel palladium-catalyzed oxidative three-component coupling of easily accessible N-substituted anthranilamides with isocyanides and arylboronic acids is achieved. This protocol offers an alternative approach toward 2,3-disubstituted quinazolinones with a wide substrate scope and good functional group tolerance.

Cu-Mediated Stereoselective [4+2] Annulation between N-Hydroxybenzimidoyl Cyanide and Norbornene.

A Cu-mediated stereoselective [4+2] annulation between N-hydroxybenzimidoyl cyanides and norbornene (NBE) has been developed for the synthesis of 4 H-1,2-oxazin-4-ones. The reaction proceeds through sequentially forming C-O/C-C bonds. The advantage of this reaction includes high stereoselectivity, excellent yields, as well as simple and mild reaction conditions.

[Screening and structure analysis of the aptamer target to Escherichia coli tolC protein].

Objective: To screen and characterize the aptamer of Escherichia coli outer member protein tolC.

Methods: By using the recombinant E.coli outer member protein tolC for the screening target, oligonucleotides which were capable of specifically binding to the protein were screened from a random oligonucleotide library through the stematic evolution of ligand by exponential enrichment (SELEX) technique.
