Summary: Three types of glandular trichomes are developed on the flowers and leaves of Millingtonia hortensis, each with specific ultrastructural traits. These trichomes contain different chemical substances and play distinct roles in attracting pollinators and protecting vegetative shoots. GC-MS analysis identified seventeen compounds in the internal pool of metabolites, including alcohols, terpenes, and benzenoids.

Summary: This study focused on the chloroplast genome of Campsis grandiflora, a plant belonging to the Bignoniaceae family. The complete chloroplast genome of C. grandiflora was analyzed, annotated, and compared with other species in the same family. The study provided insights into the structure and gene content of the chloroplast genome, and supported the phylogenetic relationship between C. grandiflora and genus Incarvillea within Bignoniaceae. The findings of this study have important implications for species identification and biological research.

Summary: Pollination syndromes are stereotyped floral characteristics associated with specific pollinators, such as bees and birds. The trumpet creeper species Campsis radicans, typically assigned to hummingbird-pollination syndrome, was found to have bees as the primary pollinators in certain populations. This highlights the importance of floral phenotypes in facilitating pollination by different functional groups.

Summary: By analyzing 166 distribution records and 11 climate and terrain variables, this study predicted the potential distribution of Campsis grandiflora under climate change and identified the dominant climate variables affecting its geographical distribution, which are temperature, precipitation, and altitude. The results showed that under future climate change scenarios, suitable habitat will increase and unsuitable habitat will decrease.

Summary: The surface of pollen grains is strengthened by components produced by tapetum cells, which are regulated by the GASSHO receptor-like kinase pathway. The pathway is controlled by sulfated peptides and requires the action of subtilases. Three types of cells coordinate to deposit pollen wall through molecular dialogue.

Summary: In this study, we conducted transcriptome analysis to understand the regulatory mechanism for anther dehiscence in rice. Through functional classification, we identified hormone signaling and transcriptional regulation pathways as important factors in anther dehiscence and anther wall development. These findings provide valuable insights into the molecular mechanisms of anther dehiscence and anther wall development in rice for future research.

Summary: The integrity of pollen wall structures is crucial for pollen development and maturity in rice. In this study, a male-sterile mutant pwa1 with defective pollen wall structure and sterile pollen was characterized. The gene LOC_Os01g55094, encoding a coiled-coil domain-containing protein, was identified as PWA1. PWA1 interacted with the transcription factor TIP2 and played a role in regulating the formation of pollen wall and mature pollen in rice.

Summary: This study investigated efficient pH and dissolved CO2 conditions for indoor and outdoor cultivation of the BX1.5 strain of Parachlorella sp., a green alga that can produce valuable lipids and extracellular polysaccharides. The results showed that the BX1.5 strain can thrive in a wide range of initial pH and can produce valuable lipids under both indoor and outdoor culture conditions when supplied with 2.0% dissolved CO2. The acidic BG11 medium was found to effectively increase the biomass of extracellular polysaccharides during short-term outdoor cultivation.

Summary: Microalgae can mitigate the effects of environmental pollution by conserving carbon footprint and generating green energy. This study focused on the Cd-tolerant algal strain Scenedesmus sp. IITRIND2 and investigated the molecular mechanisms underlying Cd tolerance and carbon flux channelization for enhanced lipid/EPS production. The study revealed metabolic rewiring and the activation of defense networks in the algal cells, resulting in the production of biodiesel quality lipids and soluble EPS. These findings provide insight into the potential of algal-based biorefinery approaches for Cd remediation and sustainable production.

Summary: The green alga Parachlorella sp. BX1.5 has been found to produce a novel acidic rhamnan of high molecular mass, which shows thickening and resistance to environmental stress conditions when added to mayonnaise. This suggests its potential application as a thickener or food additive with improved oil-off properties.

Summary: This study examines the physiological changes in fatty acids (FA) and carbohydrate (CHO) composition in Calamoceras marsupus larvae and leaf litter exposed to copper and uranium. The results show that metal exposure affects the FA and CHO content in leaf litter and larvae specimens, as well as the CHO composition in microorganisms and detritivores.

Summary: Introducing cationic lipids and using pH-responsive polysaccharides with intrinsic adjuvant function can improve the cellular association of liposomes with dendritic cells and increase cytokine production. These liposomes can promote tumor suppression by improving intra-tumoral immunosuppression and inducing antigen-specific cellular immunity.

Summary: In this study, fish oil microencapsulation was achieved using salt-soluble fish muscle protein, kappa-carrageenan, and a fish protein hydrolysate as wall materials. The drying method significantly affected the water solubility, drying yield, and rheological properties of the resulting powders. The interaction between fish muscle protein and/or fish hydrolysate with kappa-carrageenan led to the formation of protein-polysaccharide interactions, which were disrupted by the presence of fish oil. The spray-drying method produced smaller particles compared to heat-drying. Both methods resulted in high entrapment of fish oil, with the heat-dried sample showing lower water resistance, higher viscosity, and lower lipid oxidation.
