The present invention relates to plant biotechnology and specifically to a method for genetically transformingwith-mediated transformation system. It comprisesfor producing homologous and heterologous recombinant products including oil and protein products and assessing and screening the efficacy of plant transformation. Also disclosed are transgenicplants, seeds as well as cells, cell-lines and tissue of

The invention is related to a method and a DNA construct for controlling transgene segregation in a sexually reproducing multicellular organism (SRMO), especially in such SRMOs which are susceptible of interbreeding with their cultured or wild-type relatives. The method and construct allows the farmer to reuse the transgenic crop without risk for escape of the transgene into the environment. The DNA construct is a recoverable block of function (RBF) system comprising at least one blocking construct (BC), and at least one means for recovering the blocked functions. The BC has a capacity of blocking at least one molecular or physiological function essential for the development and/or reproductive cycle of the SRMO. The BC is closely linked to the transgene of intereset (TGI). The blocked function is recoverable by an external treatment or intervention, which is optionally combined with one or more recovering constructs (RC). Different types of RBFs, including single, full, delayed, double, multiple and reversed delayed RBF are disclosed.

The present invention relates to plant biotechnology and specifically to a novel transformation protocol for obtaining transgenic turnip rape plants with Agrobacterium mediated transformation. In the protocol an internode section of the inflorescence carrying stem of mature turnip rape is used as explant.

Provided are transgenic plants with resistance to viral infection polynucleotides and methods for conferring such resistance, and methods for producing the transgenic plants. Plants transformed with a nucleotide sequence encoding a P1 protein of potato virus Y result in plants having increased resistance to infection by potato virus Y.
