Summary: The effects of orbital forcing on the East Asian summer monsoon after the mid-Pleistocene transition are controversial. A study based on the 613C values of land snail shells provides a record of the past 470 k.y., which suggests that the EASM is dominated by a 100 k.y. cycle with higher values during glacials. The study also reveals that precipitation remained at an interglacial level following the end of the MIS 11 super-interglacial climate in the Northern Hemisphere.

Summary: The study examines the factors contributing to the deglacial Atlantic mid-depth delta C-13 change, finding that the increased remineralization due to the weakened AMOC plays a dominant role in the decrease of delta C-13. The surface end-members should be used in diagnosing mechanisms of delta C-13 changes, as their remineralization is more critical than that along the transport pathway to the deep ocean.

Summary: Monsoonal changes in particulate organic matter (POM) and its isotopic signatures were studied in the central Arabian Sea during August 2017 and 2018. Higher wind speed and jet-induced wind stress curl with low sea surface temperature and higher nutrients were observed in 2018 compared to 2017. The region to the north of the atmospheric jet exhibited shallower Mixed Layers Depths (MLDs) and higher POM contents, while the molar ratio between particulate organic carbon (POC) and nitrogen (PN) was very close to the Redfield ratio.

Summary: Carbon isotope fingerprinting using multivariate analysis has been applied in ecological studies to measure essential amino acids. This study evaluated the consistency in isotopic fingerprints among nearshore primary producers and identified the biochemical mechanisms driving these patterns. The results showed a high consistency in isotopic fingerprints of marine algae across space and time, with kelps and rhodophytes exhibiting distinct patterns. Taxonomy and site locality were found to be important determinants of individual amino acid delta C-13 values.

Summary: This study presents a phylogenetic analysis of diverse Euploca spp. using plastid and nuclear DNA. The results reveal multiple parallel evolution of complex features in Euploca and a significant presence of C-4 species within the genus. However, no C-4 species were found outside Euploca. Additionally, the study identifies C-3 species and species with intermediate carbon fixation pathways among the tested Euploca spp.

Summary: Observations of marine particulate organic carbon stable isotope ratios are crucial for understanding carbon cycling, but the interpretation is complicated by phytoplankton photosynthesis. By collecting and homogenizing a large dataset, insights into the temporal and spatial distribution of marine δ C-13(POC) can be gained, revealing varying trends across different ocean basins.

Summary: The study evaluated the interactive effects of temperature, pH, and nutrients on photosynthetic performance in a calcareous tropical macroalga. The highest values of gross photosynthesis were found at the highest temperature, pH, and nutrient enrichment levels. The absorption of bicarbonate was assessed through carbon stable isotope content and inhibitors assays, confirming the algae's use of both CO2 and HCO3- forms of carbon.

Summary: The study reveals the different impacts of tree-ring cellulose delta C-13 and delta O-18 in teak trees under different seasons and meteorological conditions. Additionally, the tree-ring chronology is related to rainfall and relative humidity. These findings contribute to a better understanding of the growth of tropical broadleaf trees under changing climates.

Summary: Driven by transmembrane electrochemical ion gradients, F-type ATP synthases are the primary source of ATP across all domains of life. The ATP synthase in thylakoid membranes of photosynthetic organisms has unique features, such as a larger rotor ring and a redox-regulated switch that inhibits ATP hydrolysis activity in the dark. Recent insights into the structure and mechanism of photosynthesis-involved ATP synthases are reviewed, along with exploration of the cellular physiological consequences of these adaptations in both short and long time scales.

Summary: This study investigated the isotopic signature of phytoplankton-derived POM along a north-south gradient in the western Indian shelf waters, showing differences in POM sources, growth rates, and community composition in different regions. The southern waters, influenced by upwelling, exhibited higher biological productivity, while the northern waters were characterized by oligotrophic conditions with lower nutrient concentrations.

Summary: The stable carbon isotope composition, expressed as delta C-13, in plant tissues provides valuable information about photosynthetic pathways. CAM plants utilize a more efficient form of photosynthesis compared to C-3 plants, resulting in less negative delta C-13 values. While past studies have shown bimodal distribution in CAM plant lineages, some exceptions exist. The continuum between CAM and C-3 photosynthesis cautioned against the usage of a delta C-13 threshold in macroevolutionary studies, urging for lineage-specific reconstructions rather than a unifying model of CAM evolution.

Summary: Seasonal drought is a common occurrence in Yunnan province, imposing a limitation on the growth of Pinus yunnanensis and Pinus armandii due to the scarcity of water. This study aimed to investigate the water use efficiency (WUE) of these two species. The results showed that both species exhibited higher WUE and larger delta C-13 values compared to typical subtropical species. P. armandii displayed a more conservative water use strategy with higher WUE than P. yunnanensis. Temperature and precipitation were identified as the dominant factors affecting WUE, with temperature having a greater impact on P. yunnanensis in middle-aged forests. The selection of subtropical tree species with high WUE is crucial for maintaining forest benefits under water-limited conditions.

Summary: This study investigated the antifibrotic effect of protein kinase C (PKC) in myofibroblasts and its involvement in Hippo pathway activation. The results show that PKC delta exerts an antifibrotic effect by inhibiting the Hippo pathway in hepatic stellate cells (HSCs). PKC delta and YAP can be potential therapeutic targets for fibrotic diseases.

Summary: The study examined the pollen morphology of 40 specimens of 15 species belonging to eight genera in the subfamily Salicornioideae of the Chenopodiaceae family, and found distinct pantopolyporate features. Despite extreme uniformity in pollen morphology, there is good evidence supporting currently known phylogenetic relationships and generic delimitations within the subfamily. Significant differences in pollen characters among populations of Halostachys belangeriana and Halocnemum strobilaceum may indicate genetic diversity or polyploidy in different populations.

Summary: By using a specific promoter to drive the transcriptional activator and a DNAse dead Cas9 (dCas9) activation module, the development of chloroplasts in rice bundle sheath cells can be enhanced. The results demonstrate that single gRNA expression is sufficient to regulate the transactivation of photosynthesis-associated genes.
