Identification and genetic analysis of the APOSPORY locus in Hypericum perforatum L. [PDF]

open access: yes, 2010
Der Induktion der Apomixis (Samenbildung ohne Befruchtung) in Kulturpflanzen stellt einen lang gehegten Ziel der Züchtungsforschung dar, da es die Fixierung der Heterozygotie ermöglichen würde.

Transcriptome Analysis of Differentially Expressed Genes at Pre-Meiotic Developmental Stage in Pennisetum Hybrids with Contrasting Modes of Reproduction [PDF]

open access: yes, 2020
Apomixis is an asexual reproduction through seeds where embryo develops without meiosis and fertilization. It is widely distributed throughout plant kingdom, but is more prevalent in families like Asteraceae, Rosaceae and Poaceae (Carman, 1997).

Apomixis: an enigma with potential applications [PDF]

open access: yes, 2005
Apomixis has been the focus of research in plant sciences in recent years with lot of scope for crop improvement. It results in clonal progeny without fertilization, having maternal genetic constitution.

Ploidy Dependent Expression of Apomixis Components in Guinea Grass (\u3cem\u3ePanicum maximum\u3c/em\u3e Jacq.) [PDF]

open access: yes, 2020
Apomixis is an asexual method of reproduction through seeds. The potential of apomixis has been envisaged as “asexual revolution” by virtue of its capacity to fix hybrid vigour, a much desirable feature in breeding of agricultural crops.

Pharmacologically Induced Meiosis Apomeiosis Interconversions in Boechera, Arabidopsis and Vigna

open access: yes, 2018
Apomixis is a clonal propagation method that produces offspring identical to the mother plant. With this feature, superior traits could be maintained over generations. However, our knowledge about apomixis is limited. In this study, we analyzed several apomictic Boechera embryologically to learn the details of apomixis.

Effects of Plant Stress on Facultative Apomixis in Boechera (Brassicaceae) [PDF]

open access: yes, 2015
In flowering plants, apomixis is asexual reproduction by seeds. Apomixis allows the production of offspring with the same genetic characteristics as the mother plant. Fertilization is not required.

Gametophyte interaction and sexual reproduction: how plants make a zygote [PDF]

open access: yes, 2005
The evolutionary success of higher plants relies on a very short gametophytic phase, which underlies the sexual reproduction cycle. Sexual plant reproduction takes place in special organs of the flower: pollen, the male gametophyte, is released from the ...

Seeds of doubt: Mendel’s choice of Hieracium to study inheritance, a case of right plant, wrong trait [PDF]

open access: yes, 2016
KEY MESSAGE: In this review, we explore Gregor Mendel’s hybridization experiments with Hieracium , update current knowledge on apomictic reproduction and describe approaches now being used to develop true-breeding hybrid crops.

Diploid gametes in maize by mutation of A-Type cyclins: a step towards apomeiosis and synthetic apomixis

open access: yes
AbstractHybrid crops are agriculturally desirable due to heterosis but are costly or difficult to produce. Synthetic apomixis, clonal reproduction through seed, offers the ability to fix hybrid vigor. Two components are needed to achieve this goal: the formation of diploid gametes identical to the maternal parent through apomeiosis, and the induction ...

From a Phenotype to Transcriptomics Apomixis Initiation in the genus Boechera [PDF]

open access: yes, 2009
The North American genus Boechera provides a highly polymorphic source of natural variation for studies on the regulation of apomictic development (asexual reproduction via seed).
