Techniques based on the use of plant protoplasts are a convenient model for better understanding and observing developmental changes in the cells. The establishment of research tools based on protoplasts consists of many steps needed for optimization. Here, we describe the culture of morphogenic callus (MC)- and hypocotyl-derived protoplasts of common (Fagopyrum esculentum Moench) and Tartary (F. tataricum (L.) Gaertn.) buckwheat. Protoplasts embedding in agarose matrix and application of plant hormones, including phytosulfokine (PSK), enable the development of protoplast cultures and plant regeneration.

Sugarcane smut caused by is a global sugarcane disease, and studying its molecular pathogenesis is crucial for discovering new prevention and control targets. This study was based on the transcriptome sequencing data of two isolates with different pathogenicities ( and ) of the and screened out a gene encoding the Major Facility Superfamily (MFS) sugar transporter protein and named it . Knockout mutants ( and ) and complementary mutants ( and ) were obtained through polyethylene glycol (PEG)-mediated protoplast transformation technology.

Clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated protein 9 (Cas9)-assisted genome editing has been applied to several major edible agaricomycetes, enabling efficient gene targeting. This method is promising for rapid and efficient breeding to isolate high-value cultivars and overcome cultivation challenges. However, the integration of foreign DNA fragments during this process raises concerns regarding genetically modified organisms (GMOs) and their regulatory restrictions.

The potato family includes a highly diverse cultivar repertoire and has a high potential for nutritional yield improvement and refinement but must in line with other crops be adapted to biotic and abiotic stresses, for example, accelerated by climate change and environmental demands. The combination of pluripotency, high ploidy, and relative ease of protoplast isolation, transformation, and regeneration together with clonal propagation through tubers makes potato highly suitable for precise genetic engineering. Most potato varieties are tetraploid having a very high prevalence of length polymorphisms and small nucleotide polymorphisms between alleles, often complicating CRISPR-Cas editing designs and strategies.

The role of sterols in these processes was investigated by their extraction from the protoplast plasma membrane in the presence of the oligosaccharide - methyl-β-cyclodextrin (MβCD). Depletion of membrane sterols caused by MβCD treatment did not alter protoplast volume under isosmotic conditions; however, volumes changed significantly when protoplasts were exposed to osmotic stress.
