Brazilian Archives of Biology and Technology, 2007 Microsporogenesis was analyzed in an interspecific hybrid between an artificially tetraploidized sexual accession of Brachiaria ruziziensis (2n=4x=36) and a natural apomictic tetraploid accession of B. decumbens.

Evolutionary Applications, Volume 19, Issue 3, March 2026.ABSTRACT Information on climate‐associated phenotypic variation is essential for sourcing seed that matches restoration site conditions. Spatially explicit seed transfer models can effectively deliver this information. However, standard modeling approaches often do not provide flexibility for practical considerations and may not capture highly complex ...

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1866-1884, March 2026.ABSTRACT Aegilops geniculata Roth is a tetraploid (MgMgUgUg; 2n = 4x = 28) wild relative of wheat and a valuable source of genetic diversity for improving agronomic traits. We present a high‐quality homoeolog‐resolved assembly and annotation of the Ae.

Differences in the genetic structure of citrus triploid hybrids recovered from 2x X 2x and 4x X 2x sexual hybridizations [PDF]
, 2015 Citrus triploid hybrids can be recovered by 2x X 2x hybridisations as a consequence of the formation of 2n gametes or by interploid hybridisation. Most of the 4x parents used in our program are doubled-diploid (DD), also known as autotetraploid.

Exploring the genetic diversity of the IPK Medicago germplasm collection using GBS
Plant Biology, Volume 28, Issue 2, Page 345-358, March 2026.Genotyping‐by‐sequencing of 1234 accessions from the Medicago collection of the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) revealed broad genetic diversity across 40 species, providing one of the first genus‐wide insights into relationships between both cultivated and wild species of Medicago.

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Widespread aeolian loess‐paleosol and red clay sediments on the Chinese Loess Plateau (CLP) provide a globally unique terrestrial archive of Neogene–Quaternary climate. However, the timing and associated mechanisms of red clay to loess‐paleosol shift remain debated.

Geographical parthenogenesis, genome size variation and pollen production in the arctic-alpine species Hieracium alpinum [PDF]
, 2018 Hieracium alpinum L. (Asteraceae) is an arctic-alpine species distributed throughout Europe with both diploid and triploid cytotypes. We determined the ploidy levels of plants from 23 populations from Austria, Bosnia and Herzegovina, Finland, Italy ...
