An increasing rate of endoreduplication results in cells with greater DNA content and, subsequently, increased gene expression and greater sink capacity for the developing seed.
Our study indicates that the main differences, beside the teosinte fruitcase and its absence in maize, might lay in the process of endoreduplication in endosperm," Dermastia said.
Diepoxybutane (DEB) test remains the classical "gold standard" test for diagnosis involving the detection of chromosomal breaks, gaps, rearrangements, radials, exchange, and endoreduplications
in peripheral blood cells following culturing with clastogenic agents such as DEB or mitomycin-C [9,10].
In relation to numerical CAs, only metaphases with a loss or gain of one or two chromosomes and endoreduplications were considered.
Pesticides may be able to induce a new S phase in the cell cycle and bypass mitosis, explaining the finding of endoreduplications only in the exposed group.
