The proposed hypothesis is based on numerous factsThe first of these facts is the effect of colchicine on the phenotypic ratio in an agamospermous progeny. 9,10 This was manifested, for example, in the fact that the processing of sugar beet plants AbstractThere is an attempt to explain some evolutionary processes in plants such as saltatory changes on the base of multidimensionality of plant inherited information coding. According to the suggested hypothesis, inherited information is coded by not only a nucleotide sequence but also by chromosome differential endoreduplication. It is supposed that chromosomes compete among each other for the contact with the nuclear membrane, but a change in the endoreduplication degree of various chromosome sites can result in a change of competition ability for the contact with a nuclear membrane. A simultaneous increase of chromosome endoreduplication degree of many sites can lead to an increase of nuclear membrane surface and to a change in chromosome competitive interrelations and, respectively, to a change of activity of many genes. Phenotypicaly it may manifest itself as a saltatory change of many traits.Citation: Levites EV. A new look at the mechanisms of salutatory changes in living organisms.
