The genera Boechera (A. Löve et D. Löve) and Arabidopsis, the latter containing the model
plant Arabidopsis thaliana, belong to the same clade within the Brassicaceae family …

Gametophytic apomixis is a common form of asexual reproduction in plants. Virtually all
gametophytic apomicts are polyploids, and some view polyploidy as a prerequisite for the …

• Premise of the study: The evolution of asexual seed production (apomixis) from sexual
relatives is a great enigma of plant biology. The genus Boechera is ideal for studying …

Background and aims In the Brassicaceae family, apomictic development is characteristic of
the genus Boechera. Hybridization, polyploidy and environmental adaptation that arose …

Apomixis is a difficult-to-analyse trait with a complex molecular basis and a substantive
effect on the biology of a species. Thus, apomixis is an interesting characteristic for …

Traditionally, tetraploid Paspalum notatum was considered an obligate or a facultative
apomict according to cytoembryological analyses. The degree of facultativeness was usually …

This article describes the complete microsporogenesis and pollen formation in cassava
(Manihot esculenta Crantz) at the various developmental stages (pollen mother cell …

In this study, we determined the structure of DNA methyltransferase (DNMT) genes in
apomict and sexual Boechera species and investigated the expression levels during seed …

Apomictic plants (reproducing via asexual seeds), unlike sexual individuals, avoid meiosis
and egg cell fertilization. Consequently, apomixis is very important for fixing maternal …

Sexual polyploidization has both a theoretical as well as an applied significance.
Morphological screening for large pollen grains and shape of pollen produced by the …
