Apomixis is desirable in agriculture as a reproductive strategy for cloning plants by seeds.
Because embryos derive from the parthenogenic development of apomeiotic egg cells …

Nuclear DNA amount, determined by the flow cytometry method, in diploids, natural and
synthetic allopolyploids, and natural and synthetic autopolyploids of the tribe Triticeae …

Recent molecular studies in the genera Aegilops and Triticum showed that
allopolyploidization (interspecific or intergeneric hybridization followed by chromosome …

Main conclusion Opposing changes in the abundance of satellite DNA and long terminal
repeat (LTR) retroelements are the main contributors to the variation in genome size and …

It is generally accepted that polyploids have downsized basic genomes rather than additive
values with respect to their related diploids. Changes in genome size have been reported in …

New entities in the allopolyploid Dilatata complex of Paspalum are formally described and
illustrated. Three sexual tetraploids formerly subsumed under Paspalum dilatatum are …

Peanut is an allotetraploid (2 n= 2 x= 40, AABB) of recent origin. Arachis duranensis and A.

The Dilatata group of Paspalum includes species and biotypes native to temperate South
America. Among them, five sexual allotetraploids (x= 10) share the same IIJJ genome …

Paspalum dilatatum Poir. and its related species are warm-season grasses native to the
grasslands of temperate South America. The group comprises several sexual tetraploid …

Species of section Arachis with x= 10 are important for peanut breeding and have been
organized in five different genomes (A, B, D, F and K). The few available estimates of the …
