CIRCADIAN CLOCK ASSOCIATED 1 modulates drought‐induced acid and sugar accumulation in citrus fruit
INTRODUCTION The acid and sugar levels forming the main flavor of fruit are influenced by various factors, including cultivar, cultivation techniques, and environmental change. In citrus production, drought occurring at the fruit enlargement stage promotes citrate accumulation in fruit, while it happening at the fruit maturity stage enhances sugar accumulation (Ma et al., 2023, 2024).

Comparison of the Climatic Characteristics of Ozone Valley Over the Tibetan Plateau and the Rocky Mountains
1 Introduction One of the most important trace gas species in Earth's atmosphere is ozone, which could absorb most of UV-B (280–315 nm) and all of UV-C (100–280 nm). Although ozone only takes a very small proportion of the air mass, the variation of ozone can affect both the atmospheric temperature and circulation (Li et al., 2023; Qi et al., 2022).

Ligand-enabled palladium-catalysed enantioselective synthesis of α-quaternary amino and glycolic acids derivatives - Nature Synthesis
Abstract α-Quaternary amino and glycolic acids have found application in many biologically relevant compounds and pharmaceuticals. For example, α-quaternary amino acids can act as modifiers of peptide conformation, compared with natural amino acids. Although there are numerous enantioselective methods for the synthesis of α-quaternary amino and glycolic acids through α-alkylation, α-arylation routes are challenging.
