AMC is expressed in the pollen and all cells of the mature female gametophyte Boisson-Dernier et al. It can not only quickly identify mutated chromosomes, but also distinguish male and female phenotypes 6 Montgomery and M. A novel class of MYB factors controls sperm-cell formation in plants.

Murase, K. This system relies on crossing and fertilization to obtain progeny and, thus, the plants are not self-propagating like apomicts.

Sexual dimorphism arises from genetic differences between male and female cells, and from systemic hormonal differences 123. Flies that died during the experiment were excluded in the analysis. Representative images are shown from experiments that were repeated three times.

Plant J. Finally, meiosis occurs, and a haploid bread mold germinates and grows spore-producing sporangia. GEM contains an altered centromere-specific histone H3 gene that enables paternal genome elimination after fertilization.

First, the female gametophyte plays a role in the imprinting of specific genes so that one parental allele is transcribed and the other is silenced during seed development. Recombination, which is the production of variations in gene combinations, occurs at fertilization, so bringing together new combinations of alleles.
