Leaf transcriptome differences between diploid and tetraploid bahiagrass
The Plant Genome, Volume 19, Issue 1, March 2026.Abstract Polyploid individuals of the subtropical forage grass Paspalum notatum Flüggé (bahiagrass) exhibit distinct phenotypes, including apomixis, enhanced vigor, gigas effects, and increased stress tolerance. While apomixis‐based breeding programs supported by molecular tools have improved agronomic traits such as growth habit, forage dry matter ...

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1712-1724, March 2026.ABSTRACT Induction of apomixis, or clonal reproduction through seed, could economise commercial hybrid seed production and enable smallholder farmers to save and sow hybrid seed. Here, we demonstrate the synthetic induction of apomixis in two sorghum hybrids and show that the clonal hybrid seed can be maintained across multiple seed generations.

Transcriptome analysis of the Arabidopsis megaspore mother cell uncovers the importance of RNA helicases for plant germline development. [PDF]
PLoS Biology, 2011 Germ line specification is a crucial step in the life cycle of all organisms. For sexual plant reproduction, the megaspore mother cell (MMC) is of crucial importance: it marks the first cell of the plant "germline" lineage that gets committed to undergo ...

Engineering meiotic recombination pathways in rice
Plant Biotechnology Journal, Volume 17, Issue 11, Page 2062-2077, November 2019., 2019 Summary In the last 15 years, outstanding progress has been made in understanding the function of meiotic genes in the model dicot and monocot plants Arabidopsis and rice (Oryza sativa L.), respectively. This knowledge allowed to modulate meiotic recombination in Arabidopsis and, more recently, in rice. For instance, the overall frequency of crossovers

Inheritance of Apospory in Bahiagrass, Paspalum Notatum
Hereditas, 2004 Previous studies on the inheritance of aposporous apomixis in bahiagrass showed a wide range of segregation ratios in crosses involving sexual and aposporous apomictic plants. The F1 progenies were classified through a visual progeny test carried out on few F2 plants.

Bangiales (Rhodophyta) in New Zealand: current state of knowledge and future directions
New Zealand Journal of Botany, Volume 63, Issue 5, Page 2245-2263, December 2025.ABSTRACT Members of the red algal order Bangiales are morphologically simple, with the gametophyte generation consisting of either filaments or blades, and the sporophyte generation consisting of microscopic uniseriate branched filaments. An ancient lineage, the order is distributed worldwide.

PLANTS, PEOPLE, PLANET, Volume 1, Issue 4, Page 375-386, October 2019., 2019 Wild, perennial, herbaceous plant species have the capacity to provide both agricultural products and ecological services, such as soil stability and efficient absorption, over multiple years. Although perennial, herbaceous species are common in nature, these species were rarely domesticated.
