The use of Target activation-induced cytidine deaminase (Target-AID) base-editing technology with the CRISPR-Cas 9 system fused with activation-induced cytidine deaminase (AID) resulted in the substitution of a cytidine with a thymine. In previous experiments focusing on a single target gene, this system has been reported to work in several plant species, including tomato (Solanum lycopersicum L.). In this research, we used Target-AID technology to target multiple genes related to carotenoid accumulation in tomato. We selected 3 genes, SlDDB1, SlDET1 and SlCYC-B, for their roles in carotenoid accumulation. Among 12 edited T lines, we obtained 10 independent T lines carrying nucleotide substitutions in the three targeted genes, with several allelic versions for each targeted gene. The two edited lines showed significant differences in carotenoid accumulation. These results demonstrate that Target-AID technology is a highly efficient tool for targeting multiple genes with several allelic versions.

Phthalates are synthetic compounds, well-known plasticizers, with numerous applications and reported to have adverse effects on all living organisms residing in terrestrial and aquatic environments. In this study, the rice (Oryza sativa) seedlings were exposed to di-butyl phthalate (DBP) exogenously for 7 days, with varying concentrations of 0, 200, 400, 800, and 1600 mg/L, to explore the toxicological, physiological, and biochemical consequences by measuring various parameters such as pigment, lipid, and HO (hydrogen peroxide) contents. The biochemical analysis of seedlings showed that the pigments, lipids, and HO concentrations were altered abnormally.

Chunhua loquat is a novel cultivar that effectively avoids frost damage. However, the quality characteristics of loquats are limited, and the effects of forchlorfenuron application on loquat fruit quality and bioactive substance accumulation remain unclear. In this study, forchlorfenuron was applied at concentrations of 0 (control), 10, 20, 30, and 40 mg/L to the fruit at 24 and 38 days after bloom.

Background: Spotted scat, a marine aquaculture fish, has variable body color development stages during their ontogenesis. However, the regulatory mechanism of body color patterns formation was poorly understood. Thyroid hormones (TH) function as an important endocrine factor in regulating metamorphosis.

Background: Basella alba L. (Malabar spinach) is a widely consumed leafy vegetable, well known for its nutritional and therapeutic properties. These properties arise from the availability of essential nutrients, phytochemicals, and antioxidant potential, which may vary depending on environmental factors induced by the geographical location.

This study investigated the effects of non-thermal atmospheric plasma (NTAP) treatment on the growth, chemical composition, and biological activity of geranium (Pelargonium graveolens L'Herit) leaves. NTAP was applied at a frequency of 13.56 MHz, exposure time of 15 s, discharge temperature of 25 °C, and power levels (T1 = 50, T2 = 80, and T3 = 120 W).
