Evolution of the apomixis transmitting chromosome in Pennisetum

open access: yesBMC 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.

Harnessing wild relatives of pearl millet for germplasm enhancement: Challenges and opportunities

open access: yesCrop 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.

Chromosomal Evolution and Apomixis in the Cruciferous Tribe Boechereae

open access: yesFrontiers 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.

Micro- and megagametogenesis in Cichorium intybus L.: succes sive stages and some symptoms of apospory

open access: yesActa Societatis Botanicorum Poloniae, 2014
In Cichorium intybus L., the mode of reproduction could be at the same time sexual and apomicbic. This could explain the contradictions existing in the interpretation of the heritaibidity of the characters in this species.

A Plant-Specific TGS1 Homolog Influences Gametophyte Development in Sexual Tetraploid Paspalum notatum Ovules

open access: yesFrontiers in Plant Science, 2019
Aposporous apomictic plants form clonal maternal seeds by inducing the emergence of non-reduced (2n) embryo sacs in the ovule nucellus and the development of embryos by parthenogenesis.

On the cytology of apogamy and apospory.—II. Preliminary note on apospory [PDF]

open access: yesProceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1905
Abstract Apospory is the direct vegetative process which leads from the sporophyte to the gametophyte without the intervention of spores. This phenomenon has for a long time been known to occur in mosses and ferns, and several writers have described its morphological characters, but its cytological history has hitherto remained ...

Apospory in Ferns [PDF]

open access: yesNature, 1884
MY note in NATURE (p. 151) on the remarkable mode of reproduction in ferns discovered by Mr. Druery has brought me two friendly communications, both of which deserve a few words.

Establishment of Apomixis in Diploid F2 Hybrids and Inheritance of Apospory From F1 to F2 Hybrids of the Ranunculus auricomus Complex

open access: yesFrontiers in Plant Science, 2018
Hybridization and polyploidization play important roles in plant evolution but it is still not fully clarified how these evolutionary forces contribute to the establishment of apomicts.

High-Resolution Linkage Map With Allele Dosage Allows the Identification of Regions Governing Complex Traits and Apospory in Guinea Grass (Megathyrsus maximus)

open access: yesFrontiers in Plant Science, 2020
Forage grasses are mainly used in animal feed to fatten cattle and dairy herds, and guinea grass (Megathyrsus maximus) is considered one of the most productive of the tropical forage crops that reproduce by seeds.
