Some aspects of chromosome organization in higher plants
This investigation demonstrated that: GISH provided the direct prove that two natural triploid viviparous onions Ljutika from Croatian coast and Pran from Cashmire have the same origin of triparental genome organisation. Oaks of different geographic origin and taxonomy have very similar DNA content, karyotypes, heterochromatin distribution and identical number/position of rDNA loci. Some of the genome differences between Q. robur and Q. suber correspond to repetitive dispersed DNA sequences related to retrotransposons. Both pesticides (2, 4-D) and/or plant tissue culture conditions induce chromosome changes in plant cells that is in agreement with their mutagenic activity in mammalian cells. The study made on Arabidopsis suggests the existence of a mechanism by which plants can remove active retrotransposons and thus decrease their content in a direct manner.
