Summary: Casuarina equisetifolia is widely used for agroforestry plantations for various purposes. This study established an efficient regeneration system using stem segment explants, optimizing callus induction and regeneration processes. Genetic transformation protocol using Agrobacterium tumefaciens was also optimized, leading to improved transformation efficiency to obtain transgenic plants in about 4 months. The findings will pave the way for further genetic manipulation and functional genomics of C. equisetifolia.

Summary: This study presents an optimized transformation system that improves the infection and genetic transformation frequency of immature maize embryos mediated by Agrobacterium tumefaciens. The use of LaCl3 pretreatment enhances the infection frequency, increases the proportion of positive callus, yields more positive regenerated plantlets, and significantly increases the transformation frequency from 8.40% to 17.60%.

Summary: This study established a transformation system for Tripterygium wilfordii through optimizing the concentrations and combinations of growth regulators. Genetic transformation of T. wilfordii was achieved using Agrobacterium tumefaciens and overexpression of the miltiradiene synthase gene (TwMS) resulted in increased triptolide content. This efficient genetic transformation provides a useful tool for future genetic engineering studies on T. wilfordii.

Summary: Developing an efficient transformation system is crucial for genetically engineering recalcitrant crops, especially trees. In this study, we present a stable plant transformation method for citrus genetic engineering using Agrobacterium tumefaciens. The methodology has been optimized for fourteen citrus varieties and includes infection, co-cultivation, selection, and culture media conditions. The transformation efficiency can reach 11%, and transgenic plants can be obtained in as early as six months, depending on the variety. The incorporation of helper virulence genes and antioxidants improves the transformation efficiency of specific recalcitrant cultivars.

Summary: The study aimed to develop a precise method for analyzing Withanone (WN) in rat plasma, and investigate its in-vitro ADME behavior. Results showed that WN exhibited stability and high permeability in simulated gastric and intestinal environments, with high plasma protein binding. CYP phenotyping indicated extensive metabolism by CYP 3A4 and 1A2, though it did not potently inhibit any CYP isoenzymes in rat and human liver microsomes. The findings suggest that WN could be a promising phytochemical for neurological disorders based on its pharmacokinetics and pharmacodynamics.
