Summary: This study investigated the sex-specific mating patterns and phenotypic selection on floral traits in Aconitum gymnandrum. The results showed that relative fitness increased with increasing mate number, especially for male function. The patterns of phenotypic selection on floral traits tended to be similar, with better support for selection through female fitness components. There was directional selection on larger flower number, larger flowers, and more negative nectar gradients within inflorescences. These findings shed new light on the effect of sexual selection on the evolution of floral traits.

Summary: Botrytis allii and B. cinerea are important seed-transmitted pathogens of onion. This study analyzed the chemical compositions of fir, pine, and thyme essential oils and their effects on onion seed health. The oils reduced seed infestation but also led to decreased germination and vigour. Further studies are needed to optimize onion seed treatment conditions.

Summary: Flower organ development is crucial for plant life, but onion CMS exhibits abnormal floral organ development. MADS-box transcription factors play an important role in flower development. In this study, we cloned five MADS-box transcription factors from onion flowers and analyzed their expression patterns. The results revealed that the formation of CMS onion is associated with the down-regulation of AcDEF, AcPI, and AcAG gene expression, up-regulation of AcSEP3 gene expression, and showed no correlation with AcFUL gene expression. This work lays the foundation for further investigation of the molecular mechanism of onion flower development and CMS onion male sterility.

Summary: The Neotropical orchid genus Sarcoglottis, with approximately 40 species emitting strong floral scents, relies on nectar-seeking orchid bees such as Eulaema atleticana and E. niveofasciata for pollination. The floral scent of Sarcoglottis acaulis signals the presence of nectar, attracting the bees despite not triggering stereotyped scent-gathering behavior. This self-compatible plant depends on pollinators to increase fruit set, with attributes like low nectar amount and steady-state flowering contributing to its high fruit set.

Summary: The experiment revealed that Cs-137 and Am-243 mainly accumulated in the roots of onion under hydroponic conditions, with the edible parts being relatively protected. Exposure to 243Am significantly reduced the number, length, and total surface area of onion roots. On the other hand, under the influence of Cs-137, the dry matter content in roots decreased, with an increase in the hydration level of root tissues.

Summary: Cytoplasmic male-sterility (CMS) is used for producing F-1 hybrid seeds in onions, with the gene Ms known to restore male-fertility of CMS. A single locus designated as Ms2 was found to control male-fertility restoration. RNA-seq identified reduced transcription levels of CMS-associated gene orf725 in male-fertile individuals with the Ms2 genotype.

Summary: Water scarcity has become a major issue in Morocco and other Mediterranean countries, especially in 2022. This study evaluated the use of hydrogels in onion cultivation in Meknes, Morocco, and found that the type and dose of hydrogel, as well as the level of water supply, significantly affected plant growth. The results showed that Huminsorb((R)) Polyacrylate produced the best outcomes, increasing yield by 11 t/ha compared to the control treatment without hydrogel. Furthermore, combining hydrogel application with 50% water stress saved 208 mm of water while producing similar yields to the control treatment.

Summary: Understanding the effects of water incorporation on the physicochemical properties of eutectic solvents is crucial for their application in various fields. This study demonstrates that the timing of water addition plays a significant role in influencing the conductivity, density, refraction index, and thermal stability of a fructose-citric acid-water-based deep eutectic solvent. Dilution water has a more noticeable impact on these properties, while structural water has a more pronounced effect on fluorescence intensity. The findings suggest that controlling the moment of water addition can be a strategy to shape the properties of eutectic solvents for analytical, pharmaceutical, and industrial applications.

Summary: Bioactive functional coatings, which reduce postharvest fruit losses and provide health benefits, have gained attention. This study optimized a bioactive coating based on Natural Deep Eutectic Solvents (NADES) and Larrea divaricata extract for managing postharvest diseases caused by Monilinia fructicola. The NADES composition was optimized using a Simplex Lattice design and response surface methodology, while the bioactive coating composition was optimized using a D-optimal mixture-mixture design. The optimal biocoating exhibited 72% in vitro antimicrobial activity against M. fructicola and had a smooth and uniform surface due to the NADES plasticizer.
