Summary: This study investigated plastome variations in eight species representing four genera of the Amyridoideae subfamily and Melicope, demonstrating structural variations at the borders of the plastomes in these genera and potential genetic markers. Phylogenomic analyses identified Phellodendron, Tetradium, Toddalia, and Zanthoxylum as close relatives grouped as 'proto-Rutaceae', with specific relationships between the genera and further insights into the evolutionary history provided by plastomes data.

Summary: This study conducted taxonomic and phylogenetic analyses on the genus Polyporus and its related genera, and studied the divergence times and evolutionary relationships using conserved regions of DNA fragments. The results showed that the species of Polyporus and its related genera can be divided into six different clades. Additionally, three new species of Polyporus and seven new species of Picipes were discovered.

Summary: The Eriostemon-Phebalium clade is a group of Rutaceae plants with approximately 200 species distributed in Australia, New Caledonia, New Hebrides, New Zealand, and New Guinea. While DNA sequence analyses confirm the monophyletic nature of the group, the taxonomy within the clade remains uncertain. This study explores the potential of seed morphological traits for species identification and highlights their usefulness in systematic research.

Summary: Microglia, originating from mesoderm, play key roles in the development, homeostasis, and innate immunity of the central nervous system (CNS). Their diverse morphological characteristics are closely related to their wide range of functions. However, our knowledge of the morphophysiological attributes and interactions with neurons of microglia is limited. Exploring the correlation between microglial shape and function is a current challenge and opportunity.

Summary: The pollen morphology of Clerodendrum, including 26 taxa and one species of Volkameria from China, was investigated using a scanning electron microscope. The results showed that Clerodendrum pollen grains are monads, radiosymmetric, and tricolpate, with five different types based on exine sculpturing. The study supported the close relationship between Clerodendrum and several genera in the Lamiaceae family, and suggested that traditional classification based on inflorescence and leaf characters is not accurate. This investigation contributes novel data for the classification of Clerodendrum based on pollen morphology.

Summary: This study demonstrates how the similarity in diving fronts unifies the slamming force across different diving animals and humans. By measuring the hydrodynamic forces exerted on the body during diving, the researchers evaluate the risk of muscle or bone injuries for divers at different diving heights and provide insights into the evolutionary driver for animal morphology.

Summary: Yellow seed coat in rapeseed is a desirable trait and understanding the genetic mechanism behind it can improve the quality of this oilseed crop. Through transcriptome profiling, differentially expressed genes related to seed development were identified and enriched in processes like carbohydrate and lipid metabolism, photosynthesis, and embryo development. Furthermore, candidate genes involved in seed coat color were discovered and 25 transcription factors were identified to potentially regulate the synthesis of flavonoids and phenylpropanoids, thus influencing seed color formation. These findings provide valuable insights into candidate gene function in seed development and lay the foundation for further research on the yellow-seeded trait in rapeseed.

Summary: The diversity of reproductive mechanisms in bony fishes, especially scorpaenoid fishes, is associated with ovarian structures. This study investigates the ovarian morphology of different rockfish species using histology and identifies microscopic features related to egg production. The findings suggest that these species have continuous oogenesis with multiple oocyte deposition and shed eggs more than once during the spawning season, supporting the hypothesis of indeterminate fecundity. The study also highlights the intermediate stages between oviparity and viviparity in some species of the Scorpenoidei suborder.

Summary: Larvae of Dermestidae Megatominae possess modified setae, called hastisetae, which serve as the primary defense against predators and are important contaminants of stored products and environments. Exposure to hastisetae can cause allergic reactions in humans. The study aims to increase knowledge about hastisetae, explore their diversity and morphology, and propose potential implications for the systematics of skin beetles.

Summary: A series of Ga-MFI zeolites were synthesized using a seed-assisted strategy without additional organic template. The synthesis parameters were investigated to understand the framework fabrication, morphology evolution, and gallium incorporation. The cost of tetrapropylammonium hydroxide (TPA+) was significantly reduced through the use of Si/Ga seed. Crystallization temperature and pre-aging conditions played key roles, and the addition of mineralizer and surfactant controlled morphology and gallium concentration.

Summary: A typical angiosperm flower has four whorls of organs, but not all flowers follow this rule. The male flower of Sarcobatus baileyi, for example, only has a single stamen. These unusual flowers are often underdocumented. To study the male reproductive organ of S. baileyi, we used Micro-CT, SEM, and paraffin sectioning techniques. Our findings showed that the male inflorescence of S. baileyi is more similar to the cone of conifers, with male flowers lacking perianth and being protected by peltate indusium-like shields. We also compared it with the female cone of Cupressus sempervirens to understand the evolutionary logic behind this rare male inflorescence.
