AI Article Synopsis
- The study utilized electroporation in a soybean protoplast system to create cell lines with foreign genes.
- The research involved introducing selected and unselected marker genes, either linked on one plasmid or on separate plasmids.
- The results indicated a 50% cotransformation rate for linked genes and a 18%-27% rate for independent plasmids, with consistent rates among different gene pairs.
Article Abstract
Through the use of electroporation and a soybean (Glycine max L.) protoplast system, we generated stably transformed cell lines expressing a number of foreign genes (neomycin phosphotransferase,β-glucuronidase, chloramphenicol acetyl transferase, and phosphinothricin acetyl transferase). Selected and unselected marker genes were cointroduced either linked on a single plasmid or as separate plasmids. Calli expressing multiple genes were recovered, and Cotransformation frequencies were established for both cases. Our results show a 50% cotransformation frequency in the case of linked genes. In situations in which two genes are introduced on independent plasmids, cotransformation frequencies are 18%-27%. Similar rates of cotransformation were observed among various marker pairs.

Doubled haploid (DH) technology provides an effective way to generate homozygous genetic and breeding materials over a short period of time. We produced three types of homozygous gene-edited mutants (, , and ) by CRISPR/Cas9 in durum wheat. PCR restriction enzymes and sequencing confirmed that the editing efficiency was up to 53.

CRISPR/Cas9 systems are commonly used for plant genome editing; however, the generation of homozygous mutant lines in remains challenging. Here, we present a CRISPR/Cas9-based protocol that allows the efficient generation of mutants. Gene editing was performed for the LysM receptor kinase gene and two major facilitator superfamily transporter genes.

GRF-GIF chimeric proteins from multiple source species enhance in vitro regeneration in both wild and cultivated lettuce. In addition, they enhance regeneration in multiple types of lettuce including butterheads, romaines, and crispheads. The ability of plants to regenerate in vitro has been exploited for use in tissue culture systems for plant propagation, plant transformation, and genome editing.
