Evaluation of Plant-Derived Promoters for Constitutive and Tissue-Specific Gene Expression in Potato.

Various plant-derived promoters can be used to regulate ectopic gene expression in potato. In the present study, four promoters derived from the potato genome have been characterized by the expression of identical cassettes carrying the fusion with the reporter β-glucuronidase () gene. The strengths of , , , and promoters were compared with the conventional constitutive CaMV promoter in various organs (leaves, stems, roots, and tubers) of greenhouse-grown plants.

A competence of embryo-derived tissues of tetraploid cultivated wheat species Triticum dicoccum and Triticum timopheevii for efficient and stable transgenesis mediated by particle inflow gun.

Background: The ability to engineer cereal crops by gene transfer technology is a powerful and informative tool for discovering and studying functions of genes controlling environmental adaptability and nutritional value. Tetraploid wheat species such as emmer wheat and Timopheevi wheat are the oldest cereal crops cultivated in various world areas long before the Christian era. Nowadays, these hulled wheat species are gaining new interest as donors for gene pools responsible for the improved grain yield and quality, tolerance for abiotic and biotic stress, resistance to pests and disease.

CRISPR Applications in Plant Virology: Virus Resistance and Beyond.

Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated genes (Cas) is a prokaryotic adaptive immune system which has been reprogrammed into a precise, simple, and efficient gene targeting technology. This emerging technology is revolutionizing various areas of life sciences, medicine, and biotechnology and has raised significant interest among plant biologists, both in basic science and in plant protection and breeding. In this review, we describe the basic principles of CRISPR/Cas systems, and how they can be deployed to model plants and crops for the control, monitoring, and study of the mechanistic aspects of plant virus infections.

Overexpression of Arabidopsis in Hexaploid Wheat ( L.) Alters Plant Development and Freezing Tolerance.

Jasmonates are plant hormones that are involved in the regulation of different aspects of plant life, wherein their functions and molecular mechanisms of action in wheat are still poorly studied. With the aim of gaining more insights into the role of jasmonic acid (JA) in wheat growth, development, and responses to environmental stresses, we have generated transgenic bread wheat plants overexpressing (), one of the key genes of the JA biosynthesis pathway. Analysis of transgenic plants showed that overexpression affects wheat development, including germination, growth, flowering time, senescence, and alters tolerance to environmental stresses.

Genetic transformation of einkorn (Triticum monococcum L. ssp. monococcum L.), a diploid cultivated wheat species.

Background: Domesticated einkorn (Triticum monococcum L.) is one of the oldest cultivated cereal crops in the world. Its small genome size (~ 5.

Protocol for efficient regulation of in vitro morphogenesis in einkorn (Triticum monococcum L.), a recalcitrant diploid wheat species.

Einkorn (Triticum monococcum L.) is A-genome diploid wheat that has a potential to become a useful model for understanding the biology and genomics in Triticeae. Unfortunately, the application of modern technologies such as genetic engineering, RNAi-based gene silencing and genome editing is not available for einkorn as there is no efficient in vitro tissue culture and plant regeneration system.
