Due to the variation in production technologies and process parameters, CNFs exhibit characteristic crystallinity and surface chemistry, leading to different quality and performance of the final product. This review delves into the diverse aspects of CNFs, including their sources, pretreatment approaches, and production techniques, aiming to provide a better understanding of the production-structure-functionality-application correlations, thus making it possible to more efficiently utilize biomass and their CNFs.

However, an efficient method for protoplast production remains a challenge for many economically important dicotyledonous vegetables, including lettuce (<i>Lactuca sativa</i> L.). Herein, a protocol was optimized for efficient protoplast production from various tissues (leaf and shoot apex) of different lettuce subtypes (romaine, loose-leaf, and semiheading lettuces) by optimizing the major factors affecting protoplast yielding. The optimized protocol yields protoplasts up to 2.0 × 10⁷/g (fresh weight, FW) with viability more than 85%, which is 3–10 times higher than those previously reported. This optimized protocol was also found to be applicable to other dicotyledonous plants (bok choy (<i>Brassica parachinensis</i>), celery cabbage (<i>Brassica pekinensis</i>), and <i>Arabidopsis thaliana</i>) for efficient protoplast production from leaves and shoot apexes. Moreover, an optimized poly(ethylene glycol)-mediated transient expression system (TES), using lettuce shoot apex protoplasts generated via the aforementioned protocol, exhibited high transfection efficiency exceeding 80%. This was further evidenced by the elevated expression levels and subcellular localization of four representative plasma membrane transporters: AAP2, ABCG22, ALMT10, and OATP.

Traditional molluscicides harm nontarget organisms and endanger ecosystems. Environmentally friendly molluscicides that ensure safety for humans and animals and promote sustainable agriculture are urgently needed. This study is the first to explore the fumigant toxicity, contact toxicity, and repellent effects of four monoterpenoids (geraniol, citral, geranyl nitrile, and citronellal) against <i>Philomycus bilineatus</i>. Compared to metaldehyde, monoterpenoids exhibited stronger contact toxicity, leading to rapid slug elimination (within 4 h), while metaldehyde caused death in slugs over a longer period of 48 h. Among the monoterpenoids, citral has weaker contact toxicity compared with the other three compounds, and geranyl nitrile (GN) and citronellal have stronger fumigant toxicity than the other two compounds. In terms of repellence and antifeeding effects, citral has the weakest toxicity. GN and citronellal stand out with excellent molluscidal activity (LC₅₀ values of 0.10 and 0.14 g/L, respectively). The computational results based on the density functional theory (DFT) indicate that appropriate energy gaps, electrophilicity indices, and molecular softness correlate with the high molluscidal activity of monoterpenoids. From the computational results of this study, GN and citronellal, which have a moderate energy gap (approximately 0.200 eV), show the best effectiveness in controlling the slugs. In addition, unlike metaldehydes, which have a long half-life and limited biodegradability, these monoterpenoids have low toxicity and are easily degradable in the environment, making them more environmentally friendly.

Selenium (Se) deficiency affects approximately 1 billion people worldwide, and agronomic biofortification of food crops using inorganic Se fertilizers or Se nanoparticles (SeNPs) has emerged as a potential solution. However, to ensure food safety, it is critical to assess whether nonbioavailable or toxic Se species are formed when SeNPs are introduced into plants. In this study, pot experiments with rice plants (<i>Oryza sativa</i> L.) were conducted to evaluate the effects of foliar applications of selenite (Se(IV)) and SeNPs on Se uptake, translocation, and speciation. Plant growth, chemical, and biochemical parameters were evaluated. Selenium accumulation and speciation were determined using inductively coupled plasma mass spectrometry (ICP-MS) and high-performance liquid chromatography coupled with ICP-MS (HPLC-ICP-MS). The results demonstrated that SeNP treatment did not adversely affect plant growth, grain yield, and oxidative stress or significantly increase the inorganic Se content in rice grains. From a nutritional perspective, grains biofortified with SeNPs had the potential to meet 100% of the recommended daily Se intake. Meanwhile, Se(IV) was more efficient for grain biofortification but increased the concentration of inorganic Se in rice grains by 141% compared to the control group. Regardless of the Se species applied, rice fertilization increased the proportion of selenomethionine while it reduced selenocysteine in grains. The treatment with SeNPs did not compromise the nutritional quality of rice grains but increased As content from 175 to 210 μg kg^–1, which remains below the maximum allowable limit of 350 μg kg^–1 for husked rice. The foliar application of SeNPs enables the production of Se-enriched rice with Se levels controlled within a safe range for human consumption and without significantly altering inorganic Se concentrations.
