BMC Genomics, 2020 Background Paspalum notatum exhibits both sexual and apomictic cytotypes and, thus, is considered a good model for studies of apomixis because it facilitates comparative approaches. In this work, transcriptome sequencing was used to compare contrasting P.

Analysis of variation for apomictic reproduction in diploid Paspalum rufum [PDF]
, 2014 Background and Aims: The diploid cytotype of Paspalum rufum (Poaceae) reproduces sexually and is self-sterile; however, recurrent autopolyploidization through 2n + n fertilization and the ability for reproduction via apomixis have been documented in one ...

Nordic Journal of Botany, EarlyView.Road verges can be important habitats for vascular plant communities and the organisms that, in turn, depend on them. However, the plant diversity in Swedish road verges is threatened by the invasive perennial plant Lupinus polyphyllus Lindl. Therefore, this study aimed to investigate the effects of L.

New Phytologist, EarlyView.Summary The Arctic is experiencing some of the world's most rapid changes in climate. Arctic plant flowering time responses to climate change are understudied. Globally, conflicting evidence exists on whether flowering time responses to temperature are evolutionarily conserved.

Apomixis in hawkweed: Mendel's experimental nemesis [PDF]
Journal of Experimental Botany, 2011 Mendel used hawkweeds and other plants to verify the laws of inheritance he discovered using Pisum. Trait segregation was not evident in hawkweeds because many form seeds asexually by apomixis. Meiosis does not occur during female gametophyte formation and the mitotically formed embryo sacs do not require fertilization for seed development.

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?
New Phytologist, EarlyView.Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.

Biological control of Rubus alceifolius (Rosaceae) in La Réunion Island (Indian Ocean): from investigations of the plant to the release of the biocontrol agent Cibdela janthina (Argidae) [PDF]
, 2011 The giant bramble (Rubus alceifolius Poir.: Rosaceae), native to Southeast Asia, is one of the most invasive plants in La Réunion. A ten year research program was launched in 1997 with three components: i) genetic diversity, ii) development strategy, and

Variation and geographical distribution of ploidy levels in Pennisetum section Brevivalvula (Poaceae) in Burkina Faso, Benin and southern Niger [PDF]
, 1995 #Pennisetum$ sect. #Brevivalvula$ is a species complex characterized by polyploidy and apoximis. Ploidy level was assessed by DAPI-flow cytometry for 304 plants of the section, originating from Burkina Faso, Benin and southern Niger.
