Diversity and dynamics of plant genome size: An example of polysomaty from a cytogenetic study of Tahitian vanilla (Vanilla ×tahitensis, Orchidaceae)

Abstract

Genome irregularities may be transmitted not only during vegetative propagation but also by sexual reproduction in Vanilla. However, there must be a complex regulation of genome size and organization between the aneuploidy in somatic tissues and subsequently euploid gametic tissue. This is a novel example of polysomaty with developmentally regulated partial endoreplication.
