The complex polyploid genome architecture of sugarcane - Nature
Abstract Sugarcane, the world’s most harvested crop by tonnage, has shaped global history, trade and geopolitics, and is currently responsible for 80% of sugar production worldwide1. While traditional sugarcane breeding methods have effectively generated cultivars adapted to new environments and pathogens, sugar yield improvements have recently plateaued2.
Neighbourhood species richness and drought‐tolerance traits modulate tree growth and δ13C responses to drought
INTRODUCTION The world's forests are experiencing widespread mortality events because of climate extremes like droughts (Hartmann et al. 2022). Such climate extremes are predicted to increase in frequency and intensity with climate change in many regions (IPCC 2022), threatening multiple ecosystem services that forests provide, including their capacity to mitigate climate change through carbon sequestration and storage (Anderegg et al. 2020).

Redox-Neutral Organometallic Elementary Steps at Bismuth: Catalytic Synthesis of Aryl Sulfonyl Fluorides
Organic molecules bearing a sulfonyl fluoride group (R–SO2F) have gained interest in both the fields of chemistry and biology, due to their balanced reactivity and stability under physiological conditions. Among many other applications, these functionalities have found promising applications as covalent protein inhibitors and biological probes. (1,2) However, the common synthetic methods to obtain such compounds mainly relied on the Cl/F exchange from the parent sulfonyl chloride.
SuFExable polymers with helical structures derived from thionyl tetrafluoride - Nature Chemistry
Abstract Sulfur(vi) fluoride exchange (SuFEx) is a category of click chemistry that enables covalent linking of modular units through sulfur(vi) connective hubs. The efficiency of SuFEx and the stability of the resulting bonds have led to polymer chemistry applications. Now, we report the SuFEx click chemistry synthesis of several structurally diverse SOF4-derived copolymers based on the polymerization of bis(iminosulfur oxydifluorides) and bis(aryl silyl ethers).
“Close-to-Release”: Spontaneous Bioorthogonal Uncaging Resulting from Ring-Closing Metathesis
Bioorthogonal chemistry provides tools to scrutinize and modulate biological processes. Bertozzi pioneered the field by capitalizing on the Staudinger ligation, (1) which paved the way to numerous bioorthogonal ligations. (2) The possibility of triggering organic reactions in vivo provides tools for targeted therapy. (3) Such reactions occur with high selectivity and turnover numbers (TONs) and proceed with fast kinetics under high dilution.
A New Portal to SuFEx Click Chemistry: A Stable Fluorosulfuryl Imidazolium Salt Emerging as an “F−SO2+” Donor of Unprecedented Reactivity, Selectivity, and Scope
AbstractA fluorosulfuryl imidazolium salt delivers an “F?SO2+” group to phenols and amines with phenomenal efficiency. In their Communication (DOI: 10.1002/anie.201712429), K.?B. Sharpless, J. Dong, and co-workers present the practical, mole-scale synthesis of this stable, powerful reagent that provides clickable RNHSO2F, dramatically expands the scope of SuFEx products, and constitutes a complementary alternative to SO2F2 gas delivery.
