One of the basic components of a medium influencing somatic embryogenesis of cereals from immature embryos is the type of auxin. According to some researchers, phytohormones can also play an important role during Agrobacterium-mediated transformation. In this first part of research, the influence of three types of auxins used alone or in combination of two(More)
Globodera rostochiensis and Globodera pallida are parasitic root cyst nematodes of potato (PCN), which significantly reduce yield and quality. The genetics and available molecular markers should make resistance to nematodes an excellent candidate for marker assisted selection. The study presents results of testing the suitability of known molecular markers(More)
Transgenic plants of triticale cv. Wanad were obtained after transformation using three combinations of strain/vectors. Two of them were hypervirulent Agrobacterium tumefaciens strains (AGL1 and EHA101) with vectors containing bar under maize ubiquitin 1 promoter (pDM805), and both hpt under p35S and nptII under pnos (pGAH). The third one was a regular(More)
Agrobacterium tumefaciens is a very useful vector to transfer foreign genes into dicotyledonous cells. Monocotyledonous, especially cereals, were considered outside the host range of the bacteria. The main, alternative technique of transformation developed for them was delivery of naked DNA (e.g. microprojectile bombardment, electroporation of protoplasts).(More)
Three combinations of Agrobacterium tumefaciens strains and vectors were used in the transformation of selected Polish wheat cultivars. The combinations were: two hypervirulent strains, AGL1, containing the pDM805 binary plasmid, and EHA101, containing pGAH; and the common Agro strain LBA4404, harboring the super-binary pTOK233 vector. pDM805 contained bar(More)
The possibility of combining novel monitoring techniques and precision spraying for crop protection in the future is discussed. A generic model for an innovative crop protection system has been used as a framework. This system will be able to monitor the entire cropping system and identify the presence of relevant pests, diseases and weeds online, and will(More)
