The 'Salmon' system of wheat comprises three isogenic alloplasmic lines with either zygotic (aS) or autonomous, fertilisation-independent (cS kS) embryo development. While the initiation of embryogenesis from the isolated sexual egg cell de...
Analysis of gene expression during flowering in apomeiotic mutants of Medicago spp.: cloning of ESTs and candidate genes for 2n eggs [0.03%]
蒺藜属无配子植物开花过程中基因表达分析：ESTs克隆及无配子合子候选基因的鉴定

Mutants showing features of apomixis have been documented in alfalfa (Medicago sativa L.), a natural outcrossing sexual species. A differential display of mRNAs that combines cDNA-AFLP markers and bulked segregant analysis was carried out w...
Strategies for isolating mutants in Hieracium with dysfunctional apomixis [0.03%]
用于分离功能异常的节节草的孤雌生殖突变体的方法
R Bicknell,E Podivinsky,A Catanach et al.
R Bicknell et al.
Species in the genus Hieracium subgenus Pilosella form asexual seed by the mechanism of apospory. We have reported previously that the capacity to be apomictic is inherited in these plants as a dominant trait at a single locus. The level of...
Tripsacum dactyloides (Poaceae): a natural model system to study parthenogenesis [0.03%]

Diplosporous apomeiosis, formation of unreduced embryo sacs primarily of the Antennaria type, followed by parthenogenetic embryo development and pseudogamy (fertilization of the central cell) describe gametophytic apomixis within the Tripsa...
Apospory and parthenogenesis may be uncoupled in Poa pratensis: a cytological investigation [0.03%]
羊茅中的无孢子生殖和孤雌生殖可以解偶联：细胞学研究

E Albertini et al.
Despite the potential that apomixis has for agriculture, there is little information regarding the genetic control of its functional components. We carried out a cytohistological investigation on an F1 segregating population of Poa pratensi...
Direct evidence of pseudogamy in apomictic Brachiaria brizantha (Poaceae) [0.03%]

Brachiaria brizantha is a forage grass that has several apomictic accessions. B. brizantha cv. Marandu is a natural tetraploid aposporous apomict widely cultivated in Brazil. Pseudogamy was detected in this species by observation that seed ...
Apomixis and sexuality in Paspalum simplex: characterization of the mode of reproduction in segregating progenies by different methods [0.03%]
Paspalum simplex的无融合生殖和有性生殖：通过不同方法鉴定分离后代的繁殖方式
M E Cáceres,F Matzk,A Busti et al.
M E Cáceres et al.
Segregating progenies of crosses between sexual and apomictic genotypes of Paspalum simplex were analysed for the formation of meiotic versus aposporous embryo sacs, zygotic versus parthenogenetic embryos, and autonomous versus pseudogamous...
Reproductive development in apomictic populations of Arabis holboellii (Brassicaceae) [0.03%]
无融合生殖群体中的阿拉伯芥居群的繁殖和发育研究

T N Naumova et al.
Megasporogenesis, megagametogenesis and seed formation were analyzed cytologically in populations of Arabis holboellii originating from North America (Colorado) and Greenland. The Colorado population contained only triploid plants, while th...
Autonomous endosperm development in flowering plants: how to overcome the imprinting problem? [0.03%]
被子植物胚乳的自主发育：如何克服印迹问题？

R Vinkenoog
In the vast majority of sexually reproducing flowering plants, a ratio of 2 maternally derived genomes to 1 paternally derived genome (2m:1p) is essential for normal endosperm development, and therefore ultimately for seed development. Even...
