Summary: This study reports a fossilized flower bud specimen, Archaebuda lingyuanensis, from the Early Cretaceous in China. It is the first recorded flower bud from this period, indicating that early angiosperm flowers had the ability to protect their internal parts and attract insects for pollination. This discovery is important for understanding the reproductive strategies of early angiosperms.

Summary: Comparing cellular features in microsporogenesis across taxa may provide insights into the evolution of meiosis in plants. It has been observed that bidirectional cytokinesis occurs in basal angiosperm species, but not in eudicots and monocots, suggesting it is a common feature in some basal angiosperms.

Summary: Although diverse fossil angiosperms have been reported from the Early Cretaceous, their documentation is limited due to poor preservation and limited technologies. In this study, we applied paraffin sectioning and microscopy techniques to document a new fossil reproductive organ, Xilinia gen. nov., from Inner Mongolia, China. The morphological characteristics of Xilinia indicate a transitional stage in plant evolution that is not present in extant plants.

Summary: Angiosperms, also known as flowering plants, are the most important group for humans due to their high diversity, adaptability, and wide distribution. The origin and early history of angiosperms have been debated among paleobotanists. However, the recent discovery of Qingganninginfructus, a new species of angiosperms from the Middle Jurassic, challenges previous theories and updates our understanding of the origin and early history of angiosperms.

Summary: The study tested the flower shape preferences of two native Australian bees and found that they demonstrated similar preferences to honeybees, indicating that flower shape preference may be a deep-rooted evolutionary occurrence in bees. This research provides valuable insights into the foraging strategies and preferences of non-eusocial bees, potentially contributing to the understanding of flower-pollinator co-evolution.

Summary: This study reports the discovery of fossil flowers of the mallow family (Malvaceae) from the Cenozoic sediments in Asia for the first time. The fossil flowers, identified as a new species named Bombax asiatica Hazra, Bera et Khan sp. nov, provide important evidence about the past diversity and paleobiogeography of the mallow family in the Indian Cenozoic. This finding also suggests the presence of a tropical climate in Jharkhand, eastern India, during the time of deposition.

Summary: The study investigates how the orbits of galaxies in clusters relate to the prominence of the central galaxies. Systems with larger magnitude gap between the two brightest members tend to have radial galaxy orbits, while those with smaller magnitude gap exhibit isotropic or mildly radial galaxy orbits.

Summary: The origin of angiosperms remains controversial, with some families originating in the Jurassic and supporting rapid diversification in the Cretaceous, as indicated by both molecular and fossil record analyses.

Summary: This study analyzes the large-scale structure around 16 fossil systems and finds that they are mainly located close to filaments rather than nodes. Fossil systems at higher redshifts are found in denser regions, while those with larger magnitude gaps are found in less dense environments.

Summary: Morphological diversity is an important but often neglected aspect of biodiversity, crucial for understanding evolutionary processes, ecological interactions, and biodiversity conservation. A study on angiosperm order Ericales found a latitudinal gradient of floral disparity, with the disparity decoupled from species richness. The study highlights the relevance of biodiversity parameters beyond species richness and underscores the importance of species interactions, particularly in tropical regions.

Summary: Two leaf forms from the Late Cretaceous in the Bohemian Cretaceous Basin in Central Europe are described. The new genus and species Ascarinophyllum pecinovense is characterized by its unique serrate margins and stomatal structure. The leaf is compared to similar foliage from the Early and Late Cretaceous, as well as extant basal angiosperms. Another leaf form, Todziaphyllum saportanum, is revised and compared to morphologically similar Cretaceous angiosperm foliage.

Summary: The fossil record of insect and mite galls on land plants demonstrates a rich history of evolution with periods of extinction and prosperity. From ancient times to the present, the diversity and distribution of galls have evolved continuously, influenced by environmental changes and interactions between fauna and flora.

Summary: The Neotropical plant Syngonium hastiferum is usually pollinated by plant bugs rather than beetles, which is different from its beetle-pollinated relatives. The plant has several distinctive floral traits and emits a unique scent that attracts the plant bug pollinators.

Summary: This study presents a chromosome-level genome assembly of the soursop, providing essential genomic resources for breeders and evolutionary researchers. The genome has low heterozygosity, high repeat sequence content, and annotation of a significant number of protein-coding genes. Population size reconstruction reveals a gradual contraction over time, indicating a potential correlation with Cenozoic climate changes.
