DETECTION OF SPONTANEOUS MUTAGENESIS CAUSED BY MOBILE GENETIC ELEMENTS RELATED TO THE CLASS OF TRANSPOSONS OF GERM CELLS AND BREEDING OF THE SOLANACEAE CROPS

Abstract

In Solanaceae crops the spontaneous mutagenesis caused by mobile genetic elements referred by authors to the class of the transposones of germ cells (ТGC) was found. Mutagenic activity of TGC was sown on the examples of monogenic point mutations of the gene of color tomato fruits epidermis: y + _y _y +.The transposition of TGS in chromosome «switches on – switches off» the y-gene changing its allele status. Detected in Solanaceae crops TGC is differed from founded out earlier controlling elements causing only chimeric somatic spotting.Application of the TGS-mutants can accelerate the breeding process. Using the spontaneous mutagenesis allowed to develop six varieties.
