Skipping sex: A nonrecombinant genomic assemblage of complementary reproductive modules
BioEssays, Volume 43, Issue 1, January 2021., 2021 Asexuality arises through developmental alterations with apparently unrelated origins. We show the occurrence of asexual animals and plants have a common genetic and developmental basis on a single nonrecombinant assemblage of genomic elements altering complementary reproductive modules.

Harnessing wild relatives of pearl millet for germplasm enhancement: Challenges and opportunities
Crop Science, Volume 61, Issue 1, Page 177-200, January/February 2021., 2021 Abstract Pearl millet [Pennisetum glaucum (L.) R. Br.] is one of the world's hardiest warm‐season cereal crop and is cultivated mainly in the semi‐arid tropics of Asia and Africa for food, feed, fodder, and brewing. It is mainly cultivated for its gluten‐free grains with high content and better quality of nutrients.

Evolution of the apomixis transmitting chromosome in
BMC Evolutionary Biology, 2011 Background Apomixis is an intriguing trait in plants that results in maternal clones through seed reproduction. Apomixis is an elusive, but potentially revolutionary, trait for plant breeding and hybrid seed production.

Chromosomal Evolution and Apomixis in the Cruciferous Tribe Boechereae
Frontiers in Plant Science, 2020 The mustard family (Brassicaceae) comprises several dozen monophyletic clades usually ranked as tribes. The tribe Boechereae plays a prominent role in plant research due to the incidence of apomixis and its close relationship to Arabidopsis.

A Core AFLP Map of Aposporic Tetraploid \u3cem\u3ePaspalum Notatum\u3c/em\u3e (Bahiagrass) [PDF]
, 2023 Paspalum notatum (Bahiagrass) is a perennial rhizomatous species that reproduces by aposporous apomixis. Tetraploid races (2n=4x=40) are widely distributed from Central to South America and constitute one of the most valuable natural forage grasses for ...

Gametophyte and sporophyte of tree ferns in vitro culture
Acta Societatis Botanicorum Poloniae, 2011 Experiments had been carried out on gametophytes and very young fronds of sporophytes with application of Murashige and Skoog (1962) medium. The paper described the results of 15 years in vitro experiments on 16 species of tree ferns belonging to various

BMC Genomics, 2021 Background Apomixis, an asexual mode of plant reproduction, is a genetically heritable trait evolutionarily related to sexuality, which enables the fixation of heterozygous genetic combinations through the development of maternal seeds.

Biological Reviews, Volume 95, Issue 5, Page 1442-1466, October 2020., 2020 ABSTRACT Although most plants produce all of their fruits (seeds) aboveground, amphicarpic species produce fruits (seeds) both above‐ and belowground. Our primary aims were to determine the number of reported amphicarpic species and their taxonomic, geographic, life form and phylogenetic distribution, to evaluate differences in the life history of ...

Embryological studies on Fragaria x ananassa Duch. after pollination by three species of Potentilla
Acta Societatis Botanicorum Poloniae, 2014 Embryological studies were carried out after pollinating four female varieties of Fragaria ananassa Duch. (Freja, Sonja, Mieze Schindler, Reine des Precoce) with three species of Poteiatilla (P. geoides, P. rupestris, P. fruticosa).
