Summary: Pyrenacantha volubilis was found to produce camptothecin, a high-value anti-cancer compound, in green root cultures when grown in half strength Murashige and Skoog liquid media supplemented with indole-3-acetic acid and indole-3-butyric acid. The production of camptothecin was further increased by adjusting the concentration of ammonium nitrate and sucrose, as well as by adding yeast extract and salicylic acid.

Summary: In this study, the effects of different light qualities on Cunninghamia lanceolata seedlings were investigated, showing significant impacts on seedling growth and development. Red light and far-red light were found to promote height increment, while blue light was unfavorable for root growth. Different light qualities also had varying effects on leaf area enlargement, root growth, axillary bud number, and stem elongation in the seedlings. Manipulating light quality and wavelength in controlled environments may enhance forest production efficiency and quality.

Summary: This study investigated the effects of different plant-growth regulators and concentrations on the culture of persimmon stems, induction of leaf callus, differentiation of adventitious shoots, and rooting culture. The optimal formula for inducing axillary buds and leaf callus was identified, and an efficient regeneration system for shoots and rooting of persimmon was developed. These findings provide theoretical support for the rapid and excellent growth of persimmon, care of factory saplings, and molecular breeding.

Summary: The study implemented a multilayer perceptron model of artificial neural network and connected it to a multi-objective genetic algorithm to optimize the disinfection process of Pistacia vera L. seeds, achieving 100% disinfection efficiency and as low as 7.1% phytotoxicity. Results indicated different effects of treating with different concentrations of mercury chloride, hydrogen peroxide, and sodium hypochlorite for varying lengths of time.

Summary: By optimizing the culture medium, plant growth regulators, explant developmental stage, inoculation mode, and genotype, the efficiency of adventitious shoot regeneration in Broussonetia papyrifera root explants can be significantly improved. The best regeneration conditions include specific hormone concentrations in the culture medium. Moreover, the transplant survival rate is also high.

Summary: The aim of this study was to conduct in vitro clonal micropropagation of mature mastic trees (Pistacia lentiscus L.). The study investigated browning problems in culture media, different sampling periods, and the success of genotypes. The findings suggest that the method of micrografting shoot tips onto rooted wild genotype explants may be the most reasonable method for commercial micropropagation of mastic trees.

Summary: The study suggests that 3,4-benzopyrene may act as an auxin-like substance, positively influencing adventitious root differentiation in Triarrherca sacchariflora in vitro culture seedlings. While lower concentrations had a significant positive effect, higher dosages showed inhibitory effects. This research is the first to investigate the effects of 3,4-benzopyrene on the plant endogenous signal substances involved in regulating plant growth and development, shedding light on its role in phytoremediation of PAHs.

Summary: This study investigates the antibacterial effects of liquid discharge cold plasma (LDCP) on Enterococcus faecalis (E. faecalis) planktonic cultures and root canal biofilms. The results show that LDCP treatment has a significant antibacterial effect on both planktonic E. faecalis and biofilms, surpassing the efficacy of 0.2% chlorhexidine treatment. This work suggests the potential application of liquid discharge plasma devices in root canal treatment.

Summary: Two rapid screening methods, sand culture and in vitro, were used to evaluate the response of asparagus seedlings to F. oxysporum f. sp. asparagi. Different root morphological parameters were evaluated and correlated with symptomatology and expression of defense-related genes. The results showed that in sand culture, the Foa1-inoculated cultivars did not show any disease symptoms until 7 dpi, while in vitro, the cultivars showed high susceptibility and significant induction of defense-related genes at 5 dpi.
